00:00:00Everything started with a minor change on our planet.

00:00:04First of all, people noticed that the moon had become brighter

00:00:08and a little bigger.

00:00:10But no one paid attention to it.

00:00:12It affected the tides all over the world,

00:00:14so that the water submerged the beaches,

00:00:17but it was not a tragedy.

00:00:19Many fish came closer to the shore.

00:00:21People started to find giant squid,

00:00:24cod and other creatures close to the coast,

00:00:27while they usually lived in the dark depths.

00:00:30New and stranger things happened every day.

00:00:33Birds no longer fly south in winter.

00:00:36They gather in huge swarms

00:00:38that fly around cities without a precise goal.

00:00:41The moon helped them to orient themselves in nature,

00:00:43but now they can no longer know in which direction to fly.

00:00:47From the seas,

00:00:48the ship's captains notice that the compasses are now unstable.

00:00:52The arrow points in different directions

00:00:54since the magnetic poles of the Earth have changed.

00:00:57People realize that the moon has begun to approach it

00:01:00for an unknown reason.

00:01:02The gravity of the moon affects that of our planet.

00:01:05This leads to changes in the climate,

00:01:08in the behavior of all living beings

00:01:10and in the magnetic field.

00:01:12Now it rains in the driest places

00:01:14and it's hot in the coldest lands.

00:01:17This hurts the ecosystems of the whole planet.

00:01:20People who live near forests

00:01:22often hear wolves howling

00:01:24because the moon drives these animals crazy.

00:01:27The Earth's natural satellite

00:01:29never ceases to grow

00:01:30and illuminates the night in a much brighter way.

00:01:33Nothing irremediable has happened yet.

00:01:36People still don't panic

00:01:37because they don't want to believe that the end is coming.

00:01:40But one day, the moon reaches a critical point.

00:01:44You walk down the street listening to music

00:01:46and at that moment, someone bumps into you.

00:01:49Well, this guy may be late for work.

00:01:52You keep walking

00:01:53and a passing girl bumps into your shoulder.

00:01:56Sorry, sorry, she says.

00:01:58Then she leaves.

00:02:00You could read fear in her eyes.

00:02:02You look in front of you

00:02:03and see people running in your direction.

00:02:05You finally take off your headphones

00:02:07and you hear screams and sirens.

00:02:09People leave their cars and run away.

00:02:12Hundreds of seagulls fly in the sky.

00:02:15You hear a strange noise among all this noise.

00:02:18It seems to be...

00:02:20water!

00:02:21How is this possible?

00:02:22You are in the city center, a few kilometers from the coast.

00:02:26But you don't have time to think.

00:02:28You notice that a huge wave floods the streets

00:02:31and heads straight for you.

00:02:33You run into a building and climb to the 10th floor.

00:02:37From here, you observe the water submerging the city.

00:02:40The powerful torrent carries all the cars,

00:02:42the buildings on one floor,

00:02:44and the trees on its road.

00:02:46There is a shark fin and other fish in the water.

00:02:49The fields hide in the houses and on the roofs.

00:02:52The whole city quickly plunges into a state of disaster.

00:02:56The television works in the building where you hide.

00:02:59You learn that floods occur all over the world.

00:03:02Massive tsunamis cover coastal cities.

00:03:05In some places,

00:03:06the waves reach the height of a 30-story building.

00:03:10Many cities have been torn off the map.

00:03:13The moon is too close to the earth

00:03:15and massive floods are just the beginning.

00:03:18The moon orbits around the earth

00:03:20and helps to keep our blue house on its axis.

00:03:23The moon ensures the stability of the climate

00:03:25and helps living organisms to develop.

00:03:28But now, this balance is broken.

00:03:31The moon approaches and alters the gravity of our planet.

00:03:35The moon just has to tilt slightly to the side

00:03:37to cause massive floods all over the world.

00:03:41Imagine that you hold a glass of round water,

00:03:43you see how the liquid moves from one side to the other.

00:03:46It's the same thing that's happening now with the oceans.

00:03:50But the moon doesn't just get close to us.

00:03:53It orbits around the planet and gets closer to every revolution.

00:03:57It constantly causes natural disasters

00:03:59in different parts of the earth.

00:04:01Now, the ocean floods one side

00:04:03and a few hours later, another.

00:04:06You see all the water coming back from the streets to the shore.

00:04:09It's possible that the ocean will flood the city again by the end of the day.

00:04:13Wait, it looks like the end of the day is already here.

00:04:16You notice that the sky has become dark.

00:04:19It's strange because it's only 3 p.m.

00:04:21The moon influences the rotation speed of the earth

00:04:24and makes the day go by faster.

00:04:26It now covers almost the entire sky

00:04:28and brilliantly illuminates our planet.

00:04:31You can see the huge lunar craters.

00:04:33It's so close that you can see it even when the sun is shining.

00:04:37In some places, the moon even hides the entire sun.

00:04:41The water leaves the streets and everyone goes out.

00:04:44That's when an earthquake starts.

00:04:47The road cracks and the houses collapse.

00:04:50There are landslides in the street itself.

00:04:52The tectonic plates move all over the planet.

00:04:55Imagine two magnetic balls that are getting closer to each other.

00:04:59One of the balls is the moon and the other is the core of the earth.

00:05:03In your opinion, what will happen to what is above the core?

00:05:07This represents hundreds of thousands of kilometers of our earth's crust.

00:05:12And now everything is moving.

00:05:15Destructive cracks appear all over the world.

00:05:18The highest mountains on the planet collapse and turn into a pile of stones.

00:05:23The seabed cracks and releases magma from underground depths.

00:05:27Volcanoes wake up and spit out their incandescent lava.

00:05:31Volcanic ash clouds cover the sky, hiding the sun and the moon.

00:05:37But the scariest thing is yet to come.

00:05:40The collision is inevitable.

00:05:42The moon spins around the planet like a ball in a forensic game with a hole in the center.

00:05:47This force leads to the formation of clouds all over the planet.

00:05:51The storm rumbles now, but in five minutes it will snow.

00:05:55Then the night comes and it starts to rain.

00:05:59Water droplets are made up of mud and volcanic ash.

00:06:02It is difficult for people to breathe without a gas mask.

00:06:05Atmospheric pressure is constantly changing.

00:06:08Some people have severe migraines and others have painful joints.

00:06:12But you don't have time to dawdle on this.

00:06:15Humanity must find a way to escape this collision.

00:06:18A new gravitational order will appear when the moon crashes on the earth.

00:06:23The continents will change shape.

00:06:25They will combine into one gigantic piece of earth,

00:06:28or will divide into a hundred smaller ones.

00:06:31The energy of the collision could burn all the oxygen in the atmosphere

00:06:35and make the whole planet lifeless.

00:06:38There is also no point in hiding underground because of all these deep earthquakes.

00:06:43People decide to spend their last moments with their loved ones and their families.

00:06:47The moon is getting closer and closer.

00:06:49It is now at the same distance as the International Space Station is from us.

00:06:54The moon darkens the sky.

00:06:56Many cities are in the dark because of the waves.

00:06:59Tsunamis of several kilometers high crash against the ground.

00:07:03Millions of tons of magma come into contact with the ocean.

00:07:07Billions of liters of water evaporate.

00:07:10Humidity rises in the air, mixes with ash

00:07:13and spreads on the planet in the form of a giant cumulus.

00:07:17You have finally accepted the fateful fate of our planet.

00:07:21But something strange happens to the moon at that moment.

00:07:25You notice that giant cracks appear on it.

00:07:28The moon slowly begins to split into two parts

00:07:32and this one is divided into hundreds of large pieces.

00:07:35It is collapsing.

00:07:37The earth no longer has natural satellites.

00:07:40It's just a bunch of giant space rocks.

00:07:43But why is this happening?

00:07:45There is a space around our planet called the limit of rock.

00:07:49At this place, the gravity of the earth acts stronger than that of the moon.

00:07:54This means that the forces that hold the moon together

00:07:57are weaker than those that tear it apart.

00:08:00People applaud.

00:08:02The limit of rock has saved our planet and the moon will not hit us.

00:08:06It is fragmented into millions of splinters and forms a ring around our globe.

00:08:11The earth now looks like Saturn.

00:08:14A belt of moon rocks surrounds us.

00:08:17Huge pieces destroy everything in their path,

00:08:20including space debris.

00:08:22Satellites no longer work.

00:08:24Humanity loses its means of communication and navigation.

00:08:27People will have to use paper maps again.

00:08:30Before these events, the moon maintained the orbit of our planet at a certain angle.

00:08:35Now the axis is inclined differently.

00:08:38One hemisphere approaches the sun and the other plunges into the shadow.

00:08:42In the end, the Antarctic can turn into arid deserts

00:08:45and the equator of the planet can be covered with ice.

00:08:48Winter and summer can last for years.

00:08:51The remains of the moon float around the earth,

00:08:54but some of them fall on our planet.

00:08:56Moon meteor showers destroy our cities and create giant craters.

00:09:01And all these events lead to the massive extinction of life on earth.

00:09:06It would take hundreds of thousands of years to adapt to this new world.

00:09:11Humans could live in the great void.

00:09:13The only difference being, well, everything that makes us what we are.

00:09:17We always talk about living on other planets

00:09:20and how it would be possible to adapt to it.

00:09:23But theoretically, we could already live on board a space station.

00:09:28However, in such a case, life would evolve in a completely different way.

00:09:32All this because we should get rid of the atmosphere.

00:09:36What should we humans do to adapt to life in the great void?

00:09:40Dougal Dixon developed a concept in his book

00:09:43about creatures known as vacu-morphs,

00:09:46created to survive in space.

00:09:48They are a bit like humans, but not really.

00:09:51First of all, in space, without any ambient air,

00:09:54everything is a matter of pressure.

00:09:56There is something called atmospheric pressure.

00:09:59In simple terms, how much does the atmosphere weigh on our shoulders

00:10:03and how heavy can it be?

00:10:05Most humans are used to living near the sea level,

00:10:09where there is a lot of air pressure around us.

00:10:11But in space, there is none.

00:10:14It would be exhausting for our bodies.

00:10:16Astronauts wear suits to withstand these drastic changes.

00:10:20Which means, most likely,

00:10:23that we should develop a rigid shell to protect our internal organs,

00:10:27such as robots, scarabs,

00:10:29or some marine animals capable of supporting different levels of depth.

00:10:33Having such a shell also helps to regulate the movement of molecules

00:10:37entering and leaving the body.

00:10:39This unique being from Dixon's books,

00:10:41the Homo Caelestis,

00:10:43has characteristics similar to that of crustaceans.

00:10:46You can see that it has this armor that we mentioned.

00:10:50It is designed to resist the challenges of life in orbit and in the space vacuum.

00:10:54It breathes with three lungs,

00:10:56has trapezoidal limbs to cling to spaceships,

00:10:59and sealed eyes to protect them from difficult conditions.

00:11:02These little creatures also need unique organs

00:11:05to deal with oxygen and waste.

00:11:07However, they cannot reproduce.

00:11:10Despite their incredible adaptability,

00:11:13vacuomorphs are sterile and have a limited lifespan.

00:11:17We know from movies that the extra-atmospheric space is quite frightening.

00:11:21There is a glacial cold,

00:11:23there are dangerous radiations,

00:11:25and no air at all.

00:11:26If you find yourself there,

00:11:28your blood boils or freezes instantly.

00:11:30But, despite all this,

00:11:32humans could theoretically survive in the extra-atmospheric space for a while.

00:11:37Imagine that you are suddenly ejected from your spaceship.

00:11:41In the movies, this means being immediately sent to Patras.

00:11:46But in reality,

00:11:47the thing is not as instantaneous as the screen makes it seem.

00:11:51Scientists have conducted debatable experiments in the past

00:11:55and have had a few accidents with human beings.

00:11:58Once, an astronaut found himself

00:12:00whose space suit had accidentally been depressurized.

00:12:04He lost consciousness,

00:12:06but fortunately, he was fine after the repressurization,

00:12:09although he lost his sense of taste for a while.

00:12:13In any case,

00:12:14it would seem that you could really survive a few minutes in the space vacuum.

00:12:19But it is not a very pleasant experience.

00:12:22When you find yourself in space without a suit,

00:12:25this pressure causes the air to expand in your lungs,

00:12:28which is really harmful if you hold your breath.

00:12:32In less than a minute,

00:12:33you will faint due to lack of oxygen.

00:12:35It only takes a few seconds for everything to become dark.

00:12:39However,

00:12:40there are forms of life that can perfectly resist in space.

00:12:45Researchers have discovered tiny creatures,

00:12:48called extremophiles,

00:12:50capable of withstanding all this.

00:12:52These are the most fearful survivors of nature.

00:12:55These microbes can resist insane conditions,

00:12:58such as ice cold,

00:12:59lack of air,

00:13:00and an overabundance of radiation.

00:13:02Recently,

00:13:03we sought to discover how this special bacterium

00:13:06managed in space.

00:13:08Scientists sent it to the International Space Station

00:13:11and left it outside for a whole year.

00:13:14When they examined it later,

00:13:16they discovered something amazing.

00:13:18The bacterium had not changed much in appearance,

00:13:21but had the same products of small structure,

00:13:23called vesicles,

00:13:25of external membrane,

00:13:27to protect itself.

00:13:28It turns out that this bacterium has a superpower.

00:13:31It can repair its DNA

00:13:33and fight harmful molecules

00:13:35that could damage it.

00:13:37It also changes the way it uses its energy

00:13:40to adapt to life in space.

00:13:42This could help us learn more

00:13:45about how life can exist outside our planet.

00:13:48The experiment was called

00:13:50the TANPOPO mission.

00:13:52Bacteria adapt incredibly well.

00:13:54Thus,

00:13:55we discovered that they could float in space

00:13:58for years.

00:13:59These tiny organisms can regroup in a pack,

00:14:02like small self-protective communities.

00:14:05They can thus survive

00:14:06in the difficult conditions of extra-atmospheric space.

00:14:09During a fascinating experiment,

00:14:11researchers placed particularly resistant bacteria

00:14:14outside the International Space Station.

00:14:17These bacteria were contained in small spheres,

00:14:20each as thick as five sheets of paper.

00:14:23The result is that they stayed there,

00:14:25unharmed,

00:14:26for three long years.

00:14:28Their external layers acted like shields,

00:14:31protecting the interior of all these space hazards.

00:14:34This discovery suggests that groups of bacteria

00:14:37could travel through space between planets.

00:14:40This concept is called the Panspermia,

00:14:43which essentially means the propagation of life

00:14:46throughout the entire universe.

00:14:48In other words,

00:14:49space travel could accidentally bring life

00:14:52to other planets.

00:14:53Thus,

00:14:54if we discovered a form of microbial life on Mars,

00:14:57for example,

00:14:58it could mean that it came from space.

00:15:01All this suggests that some microbes

00:15:03could survive in space.

00:15:05However,

00:15:06with more complex creatures,

00:15:08like animals,

00:15:09things get complicated.

00:15:10The most important factor in maintaining life

00:15:13is energy.

00:15:14Everything else is good to take,

00:15:15but without energy,

00:15:16we would go nowhere.

00:15:17Life also needs many chemical compounds

00:15:20mixed with the liquid state for a long time

00:15:22and in a certain space to exist.

00:15:24If there is not enough pressure,

00:15:26the liquid evaporates,

00:15:27and the space vacuum

00:15:29means that there is none.

00:15:32It would be possible for life to evolve

00:15:34inside an asteroid

00:15:35or a moon devoid of atmosphere.

00:15:37The adaptation of life to space is possible.

00:15:40Theoretically,

00:15:41these living beings in space

00:15:43could be made up of gas,

00:15:45animated clouds floating here and there.

00:15:47They could also be made up of pure energy,

00:15:50invisible,

00:15:51but capable of communicating

00:15:52through their energy levels.

00:15:54Or they could be giants

00:15:56with their own atmosphere,

00:15:58like our planet,

00:15:59with smaller creatures living on it.

00:16:02But all this is extremely improbable.

00:16:04The chances that life evolves

00:16:06in extra-atmospheric space by itself

00:16:08are therefore extremely small.

00:16:10Now,

00:16:11imagine if instead of space,

00:16:13we were talking about a planet

00:16:14with only a hard and breathless layer around it.

00:16:17Surprisingly,

00:16:18even if there is no air on the planet,

00:16:20there is always a chance

00:16:21that life can develop there.

00:16:23At least,

00:16:24if we find some traces of water there.

00:16:26Deeply under the surface,

00:16:28there could be rivers heated

00:16:30by special events

00:16:31that spit out minerals.

00:16:33Life could start there,

00:16:34far from the surface,

00:16:36where it would be safe from dehydration.

00:16:39Breathing is only one way to obtain energy,

00:16:42but there are other options.

00:16:44The light of the sun, for example.

00:16:46Think of the surface of the moon.

00:16:48There is no air there,

00:16:49but we could still use solar energy

00:16:52to survive there.

00:16:53However,

00:16:54we are deeply underground.

00:16:56With a limited access to sunlight,

00:16:59these creatures should evolve

00:17:01in an ingenious way

00:17:02to exploit alternative energy sources.

00:17:05Some could have photosynthetic capacities there,

00:17:08using special pigments

00:17:10to exploit even the smallest trace of light

00:17:13filtering through the crust of the planet.

00:17:16Others could all form symbiotic relations

00:17:19with certain bacteria

00:17:20capable of helping them to receive energy

00:17:22from the minerals

00:17:23and organic compounds present in the rivers.

00:17:26Deeply under the surface of the planet,

00:17:29rivers are not just water sources.

00:17:31They are rich in essential nutrients for life.

00:17:34These rivers cross vast underground networks,

00:17:37creating pockets of habitable environments

00:17:39where life can thrive.

00:17:41Such creatures could feed on solid minerals

00:17:44and develop shells

00:17:45to keep their interior moist.

00:17:47They should develop unique biological characteristics

00:17:50to survive in these difficult environments.

00:17:53For example,

00:17:54some species could develop a form of bioluminescence

00:17:57to locate themselves in these dark underground tunnels.

00:18:00Others could develop sensory organs

00:18:03capable of detecting subtle changes in the environment.

00:18:06Helping them locate the sources of nutrients

00:18:09and avoid danger.

00:18:11We can't stop them.

00:18:12These ecosystems would rely

00:18:14on a delicate balance of nutrient recycling.

00:18:17Microorganisms would decompose organic matter

00:18:20and release essential nutrients into the rivers.

00:18:23This, in turn, could help plants to grow.

00:18:27And plants could serve as food

00:18:29to larger creatures, and so on.

00:18:32And then,

00:18:33Who knows what could happen over the millennia?

00:18:36As the Earth's crust moves and cracks over time,

00:18:40exposing these underground kingdoms to new challenges,

00:18:43creatures adapt and evolve in response.

00:18:47In any case,

00:18:48what we have learned is that

00:18:50life is much more adaptable

00:18:52than we thought before.

00:18:54It could even survive in extremely harsh conditions.

00:18:58We may not know

00:19:00what kind of life we will discover on other planets,

00:19:03but we should not be surprised

00:19:05if we find it in the strangest and most unexpected places.

00:19:12Day 1

00:19:14A small but powerful earthquake

00:19:16shakes the city of Naples, Italy.

00:19:18Information channels report the event.

00:19:20Experts think that the Vesuvius,

00:19:22the stratovolcano of the Gulf of Naples,

00:19:24will soon explode.

00:19:26But when?

00:19:27It has already experienced many eruptions in the past.

00:19:30In fact, this is how it took shape.

00:19:32It is made up of several layers of hard lava,

00:19:34sandstone and ash.

00:19:36The last eruption of the Vesuvius took place in 1944,

00:19:40but a major explosion occurred there,

00:19:42nearly 2,000 years ago.

00:19:43It engulfed the Roman cities of Pompeii and Herculaneum

00:19:46and decimated the surrounding areas.

00:19:49Today, 3 million people live less than 30 km from the volcano,

00:19:52and 600,000 live in the danger zone.

00:19:55Large eruptions occur every few thousand years,

00:19:58usually after long periods of calm.

00:20:00And the problem is that the Vesuvius is late for its next eruption.

00:20:04But this time, the volcano is monitored by the Vesuvius Observatory.

00:20:07It has seismic stations,

00:20:09special GPS networks and satellite radars.

00:20:12To help it measure the movements of the ground,

00:20:14it also has special equipment

00:20:16to test the chemical products contained in the gases

00:20:18coming from the volcano.

00:20:20All this helps experts determine

00:20:22whether the volcano is about to explode.

00:20:24For now, the magma is more than 10 km from the surface.

00:20:28Things seemed safe yesterday,

00:20:30but now they are about to worsen.

00:20:33Day 3.

00:20:34Another earthquake occurs,

00:20:36with a magnitude of 3 on the Richter scale.

00:20:38All the equipment installed near the volcano goes out.

00:20:41The magma is rising.

00:20:43It is not yet at the surface,

00:20:45but the Vesuvius is clearly agitated.

00:20:47The other two earthquakes follow in the afternoon.

00:20:49They don't look like ordinary earthquakes,

00:20:52and geologists can see the difference in their seismographs.

00:20:55Volcanic earthquakes are 4 to 5 times smaller on the Richter scale.

00:20:59Now, the experts are certain.

00:21:02It is a matter of a few days or weeks

00:21:04before the volcano erupts.

00:21:06Some volcanoes can be agitated for months,

00:21:08even years before they explode,

00:21:10but this is not the case with the Vesuvius.

00:21:12Day 4.

00:21:14The ground begins to crack,

00:21:16as if a giant creature was trapped in the earth's crust

00:21:19and desperately trying to get out to get some air.

00:21:22Steam escapes small cracks in the ground.

00:21:25Some areas are hotter than others.

00:21:27If you went there, you would feel like you were entering a furnace,

00:21:30and you would have trouble breathing.

00:21:32Some sheep got too close to the mountain

00:21:34and fainted.

00:21:36When the farmer found them, he almost collapsed too.

00:21:39Not because of the heat, but because of the gases.

00:21:41Carbon dioxide and hydrogen sulfide are released into the air.

00:21:45The entire area around the volcano smells like rotten eggs,

00:21:48and the number of animals in the forest now stands apart.

00:21:51The nearby trees have been absorbing these gases from the ground for days,

00:21:54and they are starting to burn.

00:21:56The levels of carbon dioxide in the region are rising rapidly,

00:21:59and all detectors emit a constant sound signal.

00:22:02Day 6.

00:22:04The tremors are getting more and more frequent.

00:22:07Experts from the Vesuvius Observatory,

00:22:09which monitors the volcano,

00:22:11say that the tremors come from the magma that is pushed up.

00:22:14A few hours later, the National Emergency Alert is triggered.

00:22:17Thousands of people have about 15 days before the eruption of the volcano

00:22:20and must evacuate their homes.

00:22:22The 600,000 people in the danger zone

00:22:24start packing their bags and leave by car and truck.

00:22:27It's chaos everywhere.

00:22:29But in all this mess, some people remain motionless.

00:22:33They look around them, trying to understand what's really going on.

00:22:36Some take pictures of their homes.

00:22:38Others spread all this chaos on social media.

00:22:41But the elderly are just outside,

00:22:43looking at their homes one last time.

00:22:45They hope that all this is just a false alert.

00:22:48It has already happened, but who can really know?

00:22:51Day 7.

00:22:53It was a white night.

00:22:55Many residents have already left.

00:22:57Some kind people from other cities

00:22:59enter the region to help the residents evacuate more quickly.

00:23:03There is a huge traffic jam, but everyone was expecting it.

00:23:06That's why the evacuation started early.

00:23:08Ferries, trains and buses

00:23:10have canceled their services to help the evacuees.

00:23:13They all work according to a precise schedule

00:23:15to make sure that everyone leaves safely, without any delay.

00:23:19Some people refuse to leave,

00:23:21but their neighbors end up convincing them.

00:23:23It will take 7 days to evacuate everyone.

00:23:26And these people will disperse in other regions of the country,

00:23:29and not just in the neighboring regions.

00:23:32Day 10.

00:23:34More than half of the residents have now left the red zone.

00:23:37After all this chaos, silence reigns.

00:23:40It is interrupted by the disturbing noises of the tremors.

00:23:43Animals are also evacuated.

00:23:45Many people are now trying to escape as much as possible from the forest.

00:23:50Day 16.

00:23:52The 25 cities that were in danger have now been evacuated.

00:23:55The red zone is empty, but the tremors are getting stronger

00:23:58as if the volcano was a tiny minute ready to explode.

00:24:01White smoke rises from the great opening at the top of the mountain

00:24:04and the winds on the side.

00:24:06The melting rock moves towards the surface

00:24:08and the gases under pressure form bubbles,

00:24:10like the ones we see when we boil food.

00:24:13Suddenly, we hear some loud explosions, then an explosion.

00:24:16It is loud enough to be heard thousands of kilometers away

00:24:19and the shock wave is felt throughout Italy.

00:24:22The volcanic rock is projected into the air.

00:24:24A thick black cloud in the shape of a mushroom forms and spreads in the sky.

00:24:28The birds leave their nests and fly away in gigantic clouds.

00:24:31The red lava is burning, now spilling from the volcano like a fountain.

00:24:35As it flows down, it annihilates everything in its path.

00:24:38Then there is a slide of volcanic soil.

00:24:41A part of the mountain in the shape of a cone detaches

00:24:43and millions of tons of earth and rocks detach from the side of the volcano and collapse.

00:24:48The lava spreads over the slopes and slowly slides towards the forest and agricultural land.

00:24:52The panache of ash, sandstone and other types of rock

00:24:55has risen so high in the sky that people can see it from Rome.

00:24:58Finally, the tower of debris begins to fall back on the earth.

00:25:02First come the ashes, then pieces of rock.

00:25:05The ash in the atmosphere is so dense that it is difficult to breathe.

00:25:08The lava spreads slowly in the region and hits all the trees.

00:25:11All the neighboring cities are enveloped in smoke and plunged into darkness.

00:25:15The buildings collapse and all around a mixture of burning toxic gas and rocks

00:25:19moves faster than a car.

00:25:21Other rocks and more volcanic ash fall to kilometers from the volcano,

00:25:25hitting cars and destroying roofs.

00:25:28The sky is completely black because the lava continues to arrive.

00:25:31The neighboring cities are gradually submerged under the melting rock.

00:25:35Some of the lava even reaches the sea.

00:25:38A gigantic white steam covers the shore where it falls and the magma becomes black.

00:25:42Now a strange neon blue fire appears on the slopes of the Vésuve.

00:25:46This fire is caused by the combustion of sulfuric gas.

00:25:49It escapes at high pressure from the cracks on the surface of the volcano.

00:25:52When they come in contact with the air, they ignite.

00:25:55These blue flames can reach five meters high in the air.

00:25:58Now all flights nearby are canceled and many planes have to change routes

00:26:02to reach their destination.

00:26:04Since the national alert, no plane has been allowed to fly over the volcano.

00:26:08The clouds of volcanic ash can damage the jet engines and other plane components.

00:26:13The water is now contaminated by currents of volcanic ash and smells incredibly bad.

00:26:18In a short time, this magma has made entire cities disappear.

00:26:22Only the roofs of the largest buildings are visible.

00:26:24After the big explosive eruption, there are smaller and quieter ones.

00:26:28At this stage, no one still knows if the volcano has stopped erupting

00:26:32and no one can approach the area.

00:26:35Ten years later.

00:26:37Most parts of the red zone are now hidden under hardened lava, but still hot.

00:26:41Including the former site of Pompeii.

00:26:43Some people have begun to forget what happened.

00:26:46Others have started their new lives elsewhere.

00:26:48And some don't even want to think about what happened to their old house.

00:26:51But several of them count the days they have left before they can go home.

00:26:56100 years later.

00:26:58You walk in what seems to be a vague field of volcanic ash.

00:27:01You suddenly realize that you are standing on the roof of the city of your great-grandparents.

00:27:05Everything is now submerged under a thick layer of hardened lava.

00:27:09But below all this, everything is still intact.

00:27:13Completely frozen in time.

00:27:16It's a beautiful day for a boat ride in the swamp.

00:27:20If there weren't enough mosquitoes, the day would be perfect.

00:27:23But for some unknown reason, the mosquitoes continue to grow as you plunge into the swamp.

00:27:29At first, they were tiny insects, almost invisible.

00:27:32And they can now be the size of your thumb.

00:27:35You can hear their growl when they pass in front of you.

00:27:38You plunge deeper to find out why they are so big.

00:27:42Finally, you see a large swarm of mosquitoes, the size of your hand, swarming.

00:27:47They notice you and start flying towards you.

00:27:50You grab a branch and start whipping the air to crush them.

00:27:53You run to your boat and try to escape.

00:27:56But they follow you and some manage to land on you.

00:27:59You crush them.

00:28:00But others, the size of basketball balls, come out of nowhere.

00:28:04You start your boat and return at full speed to the mainland.

00:28:08When you arrive, you see everyone running away, panicking because of the giant mosquitoes.

00:28:13Some of them are as massive as big dogs.

00:28:16People take refuge under the picnic tables, while others run to their cars and start running.

00:28:22You get off your boat and run to the nearest supermarket, at the same time as dozens of people.

00:28:28Employees lock the doors.

00:28:30But through the large windows, you can see the mosquitoes multiplying.

00:28:34They are getting bigger and bigger.

00:28:36There is even one as big as a car, passing by.

00:28:39It is so heavy that it landed on an empty car and crushed it.

00:28:43People crowd at the back of the store.

00:28:45You try to calm everyone down and tell them not to make any noise.

00:28:49The mosquitoes land on the window sill and block the natural light.

00:28:53It starts to get dark inside.

00:28:55Someone increases the volume of the television to broadcast the latest news.

00:29:00Mosquitoes spread all over the continent, destroying natural resources and invading cities.

00:29:06People are invited to stay inside until further notice.

00:29:10Mosquitoes notice that there are people in the store.

00:29:13So they try to force their way in.

00:29:15A mosquito the size of a car flies into the sky, unaware of what is happening below.

00:29:20Everyone hears the noise coming from the back of the store.

00:29:23Employees realize that they have not locked the door.

00:29:27A big mosquito comes in and turns everything upside down.

00:29:30Everyone runs in all directions, panicking, throwing objects at it at random.

00:29:34Some people take a fire extinguisher and wait until it flies away to the back of the store.

00:29:39Employees lock the door and the barricade so that nothing can enter.

00:29:44Everyone waits nervously.

00:29:46The television broadcasts a live report on the giant mosquitoes that fly everywhere.

00:29:51A helicopter is forced to land because the mosquitoes fly furiously in the sky.

00:29:56Everyone shivers hearing the noise of other mosquitoes buzzing near the back door.

00:30:02Hours go by and other mosquitoes keep coming.

00:30:06There is no one outside.

00:30:08And a large part of urban development and the park is destroyed or invaded by giant insects.

00:30:14Some people squint as they can while others sleep.

00:30:18A special bulletin interrupts the report and shows that there would be armored buses

00:30:23to take people near the picnic area on the highway.

00:30:26These buses will not go to the hot spot in the city center because it would be too dangerous.

00:30:31The only way to get on board is to be on the highway in two hours.

00:30:35Everyone is trying to call their loved ones,

00:30:37but the cell phone towers have been destroyed and no one can call anyone.

00:30:42The mosquito that introduced itself a moment ago destroyed the only fixed line that was present.

00:30:47People are arguing to know if they should stay or leave.

00:30:51Other insects cover the only clear areas of the sky until the sun disappears.

00:30:55People are divided into two groups, those who want to leave to take the bus and those who want to stay.

00:31:01Employees know a crossroad that can quickly lead to the highway.

00:31:05The only problem is that it will take about 20 minutes on foot because there are no more cars on the road.

00:31:11The path is delicate.

00:31:12First, you will have to escape through the main entrance and head towards the forest behind the boulders.

00:31:18From there, you will have to enter a building and then go down the sewers, which will lead to the lake next to the highway.

00:31:24The first group decides to leave.

00:31:26They prepare supplies for the escape.

00:31:29Every second, new mosquitoes arrive, darkening the sky.

00:31:33People equip themselves with everything they can find to protect themselves.

00:31:36Mosquitoes are attracted by the carbon dioxide that people exhale and they know that there is a source from the store.

00:31:44Once everyone is ready, the members of the expedition take torches of fortune and light them.

00:31:48They add a little alcohol to burn to keep the fire.

00:31:51You are part of the group that plans to escape.

00:31:54The doors open and everyone flees behind the boulders.

00:31:58Many mosquitoes try to attack you, but the smoke of the fire repels them.

00:32:02Every second, new mosquitoes invade the sky and the surroundings.

00:32:06Many people end up running into the store because they could not pass the boulders to reach our building.

00:32:13Finally, the rest of the group, including you, run towards the building.

00:32:16But it is locked and no one can knock on the door.

00:32:20Plan B is to break a window and crawl inside.

00:32:24You grab a stone and break the window closest to you.

00:32:28The only problem is that mosquitoes can follow you inside.

00:32:32So without any other option, you run to the basement of the building to find the entrance to the sewers.

00:32:38Phew, you found it and everyone goes down.

00:32:41No mosquitoes in sight, only rats.

00:32:44You plunge into the water of the sewers to your knees, but you should reach the river in a few minutes.

00:32:51The problem is that the sewers do not lead to the lake, but somewhere at the bottom of the sewers.

00:32:57You follow it anyway until you see what looks like an exit.

00:33:01So you go out and you find yourself near a collector where all the rejected waters lead next to the swamp.

00:33:07The only problem is that you are no longer next to the highway and time is running out.

00:33:11New mosquitoes invade the air, but they are not really interested in you.

00:33:16You notice creatures the size of cats floating on the water.

00:33:20They are mosquito babies or larvae and they come to you.

00:33:25You and everyone else swim to save your life until they arrive.

00:33:29The giant alpha mosquito flies into the air and dives to try to catch someone, but it fails.

00:33:36Everyone arrives at the thick swampy area where no giant mosquito can penetrate.

00:33:41You cover yourself with branches to protect yourself.

00:33:44There are 15 minutes left before the arrival of the armored bus.

00:33:47Since mosquitoes cannot enter, this will be the best place to hide in the meantime.

00:33:52Darkness falls and still no bus. It's been 3 hours and nothing.

00:33:57Mosquitoes are still buzzing and everyone feels uncomfortable under the thick bushes.

00:34:02After a while, you hear an engine and see lights flashing on the highway.

00:34:06Everyone gets up and runs to the bus.

00:34:09But you stop them so as not to attract the attention of the mosquitoes.

00:34:13You voluntarily carry yourself to sneak away and stop the bus.

00:34:16Then everyone else will be able to follow without drawing too much attention.

00:34:20You move a few branches, make some tree barks and crawl to the highway.

00:34:25You try to hold your breath so as not to make too much noise.

00:34:29You reach the edge of the road and shake your arms to stop the bus.

00:34:32It stops and the door opens.

00:34:34You tell the rest of the people to come and they join you.

00:34:38Everyone is inside and safe.

00:34:41A few mosquitoes notice you and start pecking the bus.

00:34:44But the armor is solid.

00:34:46The bus goes in search of other people along the road.

00:34:49And suddenly, a real colossus lands in front of him.

00:34:52The bus stops and you see a mosquito the size of a Boeing 747.

00:34:57He looks you straight in the eye.

00:34:59He prepares to attack.

00:35:01But the bus accelerates under his feet and leaves.

00:35:04The mosquito flies away and tries to catch up with the bus.

00:35:07But you enter a tunnel that leads to the other side of the mountain.

00:35:11After a few minutes, you arrive in an open area, without trees or buildings.

00:35:16The bus accelerates while dodging the obstacles on its way.

00:35:20Finally, you notice that you are near the supermarket where you took refuge.

00:35:25The bus opens the door so that everyone inside is taken to a safe area.

00:35:30Volunteers explain that the whole world is invaded by these giant creatures.

00:35:35By the way, you see a hybrid mosquito that has two heads and a tail of scorpions.

00:35:40It is as big as the Statue of Liberty and it is ready to attack.

00:35:44This causes the abnormal growth of these mosquitoes but also transforms them into hybrids and mutants.

00:35:50The day had started so well.

00:35:53Another completely crazy thing happened to me recently.

00:35:56It was a Sunday morning and I fried eggs for breakfast.

00:36:00But something was really wrong.

00:36:02I wasn't sure if it was the eggs or me.

00:36:05You've already tasted the eggs on the plate, haven't you?

00:36:07They normally taste like... the egg.

00:36:10But this time, in addition to the egg, I could taste the lemon, vanilla yogurt and even paper.

00:36:16And it's not as good as you might think.

00:36:18The yogurt is good in itself, but with the eggs, it's disgusting.

00:36:22Whatever the reason, I decided that it didn't bother me to have tea that day.

00:36:26But as soon as I tried, I spat it all out.

00:36:29What was that? A spoon of black pepper?

00:36:33I needed to drink water as soon as possible.

00:36:35I took a glass and, fortunately, it was just an ordinary glass of water.

00:36:39I tried to eat strawberries, but in addition to the normal taste of strawberries, they had a strong taste of pepper.

00:36:45Not the best combination, to be honest.

00:36:48It seemed that something had happened to all the food in the house.

00:36:51I also had an orange juice, so I drank a glass.

00:36:54Surprisingly, the taste was very good.

00:36:56Suddenly, I had a weird idea.

00:36:59Did I taste the colors?

00:37:01It was so crazy and strange that I needed to verify this theory immediately.

00:37:06I admit it, I licked the back of my cell phone.

00:37:10It really tasted like yogurt and vanilla.

00:37:13Just like the egg.

00:37:14So it was true.

00:37:15I could taste the colors that mingled with the original taste of each food and it was crazy.

00:37:21I wanted to go to the doctor, but even if this new superpower was weird, it was still a bit exciting.

00:37:27Also, I couldn't wait to know what the other flavors were.

00:37:31So I went to a supermarket and I bought a pack of felt.

00:37:35I got to the table, I opened the yellow one and I licked it.

00:37:39It tasted like lemon.

00:37:41So I licked each of them and I made a list.

00:37:44The pink had a strawberry taste, the red was chili, the orange was an orange.

00:37:49The blue was very bitter, the light blue was salty and the purple was blueberry.

00:37:54The black was black pepper, the beige was nutmeg, the gray was paper and the green had a taste of ... of vomit.

00:38:03Conclusion, I no longer eat green food from now on.

00:38:07I'm not particularly sad to be told.

00:38:10I only had one color left, brown.

00:38:13I was very reluctant to try, but I had to find a solution.

00:38:17To my great relief, it tasted like coffee.

00:38:20I don't like coffee, but it could be worse.

00:38:23I knew I had to go see my doctor, but I wanted to live with this superpower a little longer.

00:38:29It doesn't happen to you every day, you know.

00:38:31So I decided to go to the doctor the next day.

00:38:34And today, I had to learn to live with this ability.

00:38:37I had to avoid putting in my mouth everything that was black, gray, blue and green.

00:38:42Not only food, but also dishes and cutlery.

00:38:45And I had to find what foods I could eat, because I didn't like the strawberries that tasted like pepper.

00:38:51So I went to the store to buy transparent dishes.

00:38:54As I walked, I thought about my menu of the day.

00:38:57Orange juice, it goes.

00:38:59Strawberry yogurt, vanilla and lemon too.

00:39:02I could make a fruit salad with mango, raspberries and grapes, bananas and yogurt.

00:39:07But that's all I could find.

00:39:09By biting my lip, I realized it tasted like strawberries.

00:39:13In the store, it was quite easy to find a transparent bowl, but spoons and forks were a problem.

00:39:19I think I had to go to all the stores in the city before I could find my happiness.

00:39:23As soon as I got home, I cut all the fruits and I made a nice salad.

00:39:28I didn't eat much that morning, as you remember.

00:39:31Honestly, it was the best salad of all time.

00:39:35I saved money, since I didn't have to buy berries, oranges and lemons, but the taste was there.

00:39:41As I was tasting my meal, the phone rang.

00:39:44It was my grandmother, and she invited me to dinner that night.

00:39:47I tried to tell her that I couldn't come, but she didn't want to hear anything.

00:39:52Come on, grandmother, you know it's impossible to avoid a meal when they want to feed you.

00:39:58So she told me that she didn't want to hear any excuses and that I had to be at home at 6 p.m.

00:40:04This meant that I couldn't wait until the next day.

00:40:07I had to go to the doctor on the field and get rid of this superpower

00:40:11before my grandmother made me eat vomit and drink black pepper tea.

00:40:15I checked the time. I only had 20 minutes before my doctor left,

00:40:20and the medical center was several blocks away from home.

00:40:23I finished my salad and I ran out of the apartment.

00:40:26I got to the clinic five minutes before the office closed,

00:40:29and I asked my doctor if he could see me because I had an emergency.

00:40:33To my great relief, he agreed.

00:40:36When I explained to him that I could taste the colors,

00:40:39he looked at me with a perplexed look and probably thought it was a stupid joke.

00:40:44So I told him the whole story.

00:40:46The fake dish for breakfast and how I bought and tasted all the markers,

00:40:51that purple was a blueberry and green was not like an apple as he might have thought.

00:40:55I spent hours trying to find a transparent spoon and fork.

00:40:59To be honest, in my head it sounded better and made a lot more sense.

00:41:04The doctor was quiet and a little suspicious.

00:41:07He took my temperature, my blood pressure and looked into my mouth.

00:41:11So you ate markers, he said with a smile.

00:41:14Oops, I guess my tongue was the color of a rainbow.

00:41:18It doesn't seem really normal for an adult.

00:41:21The doctor obviously didn't believe me,

00:41:23so he just let me go by recommending me a good night's sleep.

00:41:27I guess I was stuck with that, and I had to go see my grandmother.

00:41:31Unfortunately, there was no way she could give me strawberry yogurt for dinner.

00:41:36I went home to get my new blankets,

00:41:39at least not to have the taste of paper when I ate with my grandmother's gray metal fork.

00:41:44I still had a few hours, so I did some research on Google,

00:41:48but I still couldn't find a solution.

00:41:50I thought I might be able to get rid of it by drinking,

00:41:53so I put 4 liters of water in it, but it didn't help.

00:41:57So I went to my grandmother's, dragging my feet.

00:42:00I couldn't give a rabbit to my grandmother.

00:42:02She was so happy to see me,

00:42:04and told me that she had prepared my favorite broccoli pancakes,

00:42:07especially for me.

00:42:09Yes, maybe yesterday they had been my favorites,

00:42:12but that was definitely no longer the case today.

00:42:16I tried to tell her that I wasn't hungry,

00:42:18and that I could just drink a little orange juice,

00:42:21but of course she didn't want to know anything.

00:42:24She gave me a plate with 5 pancakes and a cup of black tea.

00:42:28Suddenly, I had an idea to get rid of at least the taste of pepper

00:42:32by putting a piece of lemon in the tea.

00:42:34It would turn brown.

00:42:36So it would be a coffee tea instead of a pepper tea.

00:42:39I was lucky, my grandmother had lemon,

00:42:41so the tea problem was solved.

00:42:43But the worst was the pancakes,

00:42:45and my grandmother looked at me very enthusiastic and happy.

00:42:48I had to eat.

00:42:50I tried to control my facial expression,

00:42:52and to look super happy,

00:42:54as if I was eating the best food on the planet,

00:42:57even if it was the most horrible meal of my life.

00:43:00And yes, I drank a lot of my coffee tea.

00:43:03Finally, 3 cups.

00:43:05But when I finished and thanked my grandmother,

00:43:08she was so happy that I understood that having eaten vomit was worth it.

00:43:12It turned out that my grandmother had a vanilla yogurt,

00:43:15so I ate everything she had to get rid of the taste

00:43:18that I still had in my mouth after the pancakes.

00:43:21On my way home, biting my lip to the strawberry,

00:43:24I was thinking.

00:43:25I had to find a plan to get rid of this ability.

00:43:28But I couldn't think of anything,

00:43:30so as soon as I got home,

00:43:32I fell asleep, even if it was only 9 p.m.

00:43:35I slept for 11 hours,

00:43:37and the next morning, I made a fruit salad with yogurt.

00:43:40Once again.

00:43:41I guess that from that moment on,

00:43:43it was going to be the meal of the rest of my life.

00:43:46I was eating it with my transparent fork,

00:43:48and I was watching a TV show

00:43:50when I suddenly realized

00:43:52that I couldn't perceive the taste of the lemon

00:43:55and no orange either.

00:43:57I bit my lip,

00:43:58and it had no taste anymore.

00:44:00With trembling hands,

00:44:01I opened the fridge to take my strawberries.

00:44:04I ate one,

00:44:05and it tasted like a normal strawberry.

00:44:07No pepper.

00:44:08Everything was back to normal,

00:44:10as if nothing had happened.

00:44:12But I swear that it happened.

00:44:14Really.

00:44:17You spent all your life doing research on microorganisms.

00:44:20In recent years, you have created a device

00:44:22that can make you reptile.

00:44:24And finally, it is ready.

00:44:25At first, you wish to shrink yourself to the size of an inch

00:44:27to be able to see some microbes with the naked eye.

00:44:29And then, after several experiments,

00:44:31you hope to shrink yourself to the size of a bacterium.

00:44:34To make the experiment safer,

00:44:36you put on a special suit,

00:44:38which looks like a space suit.

00:44:40It is equipped with a survival system.

00:44:43You direct a beam of the device towards yourself.

00:44:46The beam must modify your mass and your volume.

00:44:49To return to the previous state,

00:44:50you must stand on a round platform

00:44:52the size of a hockey stick.

00:44:54You place it near your feet

00:44:56to be able to easily climb on it when you are smaller.

00:44:58You press the button and activate the machine.

00:45:01Oops, there is a problem.

00:45:03The device makes a mistake

00:45:04and shrinks you not to the size of an inch,

00:45:06but to a size a thousand times smaller,

00:45:08directly to the size of a bacterium.

00:45:10Damn, you realize

00:45:12when a fly as big as a plane

00:45:14passes in front of you during shrinkage.

00:45:16You become so small that the hairs of the carpet

00:45:18on which you found yourself

00:45:20seem to have the size of a huge tree.

00:45:22Do not panic.

00:45:24You must find the pallet, hold on to it

00:45:26and you will find your normal size.

00:45:28It was just next to your feet,

00:45:30only one centimeter away.

00:45:32Wait, but what is a centimeter now?

00:45:34When a thousand specimens of your size

00:45:36can stand on the tip of a human hair.

00:45:38You decide to climb

00:45:40a hair of the carpet

00:45:42to see where the pallet is.

00:45:44You can not even see the ceiling of the laboratory.

00:45:46The room is blurry because of its huge size.

00:45:48You are surrounded by thousands of bacteria.

00:45:50They are very different in size and color.

00:45:52But you can identify

00:45:54three main forms.

00:45:56Round bacteria that look like spheres

00:45:58are cocci.

00:46:00They can merge with each other

00:46:02and increase in size.

00:46:04There are also cylindrical bacteria

00:46:06in the form of capsules,

00:46:08resembling sausages or bananas.

00:46:10These are bacteria called spirals.

00:46:12At the end of their body

00:46:14they have a cilium resembling a hair.

00:46:16Bacteria are essential

00:46:18for our planet.

00:46:20They help produce oxygen

00:46:22and absorb carbon dioxide.

00:46:24They purify water and air,

00:46:26digest food in our stomach

00:46:28and improve our immune system.

00:46:30They crawl on the ground,

00:46:32everywhere on the carpet.

00:46:34You start climbing on the hair.

00:46:36On your way, you meet cocci

00:46:38that look like huge potatoes,

00:46:40spirals like spaghetti.

00:46:42After a few hours,

00:46:44you have finally reached the top of the hair.

00:46:46For you, it was a long time,

00:46:48but in reality, only a few minutes have passed.

00:46:50The smaller you are,

00:46:52the slower time goes by.

00:46:54Do you remember how difficult it is

00:46:56to see your movements in slow motion?

00:46:58Looking around you,

00:47:00you see an infinite forest of hair.

00:47:02In the distance, you can see the silhouette

00:47:04of a large flat mountain top.

00:47:06It seems bigger than Everest.

00:47:08Great, now you have to get there alive.

00:47:10Suddenly, a huge bacteria

00:47:12attacks you from below.

00:47:14These are several bacteria together.

00:47:16They look like a lot of sausages.

00:47:18To escape,

00:47:20you jump down.

00:47:22You weigh so little that falling from any height

00:47:24is dangerous.

00:47:26You run through the dense forest.

00:47:28You notice that almost all the bacteria

00:47:30are heading towards you.

00:47:32Most of them eat organic materials

00:47:34such as glucose or glucose.

00:47:36And right now, bad luck,

00:47:38you are the biggest source of glucose in the area.

00:47:40Smaller microbes stick to your legs,

00:47:42arms and face.

00:47:44You shake them and you fall.

00:47:46Several basils, joined together,

00:47:48approach, but then a round object

00:47:50with spikes the size of a football ball

00:47:52You see a lot of these balls

00:47:54and you realize that they are viruses.

00:47:56Microorganisms

00:47:58that cannot live without bacteria.

00:48:00To reproduce, they must infect

00:48:02a living being.

00:48:04Viruses have penetrated a bacteria.

00:48:06The other bacteria that followed you

00:48:08are also attacked.

00:48:10You see a gigantic bacteria that looks like

00:48:12a plane without wings.

00:48:14It's a type of cocci.

00:48:16Several big balls attached to each other

00:48:18and about to eat it.

00:48:20You see a small spicy football ball

00:48:22that penetrates its body.

00:48:24The bacteria shivers and freezes.

00:48:26After a while, a hole appears in it

00:48:28and hundreds of thousands of viruses fly away.

00:48:30They are everywhere and look for a new host.

00:48:32Spicy balls fly towards you

00:48:34at high speed.

00:48:36You catch a piece of plush

00:48:38and swing it like a baseball bat.

00:48:40You fight the viruses one by one.

00:48:42Your bat ends up breaking and you run away.

00:48:44You seem to be safe now.

00:48:46You enter a huge field.

00:48:48There is nothing here but bacteria.

00:48:50You realize that it's a little stain

00:48:52on the carpet that you accidentally burned

00:48:54a few months ago.

00:48:56There are a billion microbes here

00:48:58and they multiply at a crazy rate.

00:49:00A bacteria increases in size and divides into two.

00:49:02After a few minutes,

00:49:04these two bacteria grow and also divide.

00:49:06They are now in the number of four.

00:49:08The colony of bacteria

00:49:10grows exponentially.

00:49:12With such a fast rate of reproduction,

00:49:14a single bacteria can create a progeny

00:49:16weighing about one ton in 24 hours.

00:49:18After five days,

00:49:20the bacteria will be able to fill

00:49:22all the seas and all the oceans.

00:49:24Fortunately, the speed at which they divide

00:49:26is equal to the speed of their destruction.

00:49:28Dryness, a ray of light,

00:49:30a high temperature,

00:49:32humidity, all these phenomena

00:49:34control the population of microbes.

00:49:36But in ideal conditions for them,

00:49:38the bacteria could take over the whole world.

00:49:40You would make your way

00:49:42in a field of microorganisms.

00:49:44The large bacteria consume the small ones.

00:49:46They multiply and are destroyed.

00:49:48It's a boiling sea of life.

00:49:50You feel that your foot is stuck.

00:49:52You walked on something sticky.

00:49:54Just below,

00:49:56a large spherical bacteria crawls out of the ground.

00:49:58It is connected to other bacteria

00:50:00and has no precise shape.

00:50:02It looks like a pulsing biomass without shape.

00:50:04The thing clings to your body.

00:50:06It envelops you.

00:50:08You feel like you're being absorbed by hot ice.

00:50:10The bacteria compresses your chest.

00:50:12It is now difficult for you to breathe

00:50:14and move.

00:50:16At that moment, something that looks like a metal screw

00:50:18plunges into the bacteria.

00:50:20A large diamond then erupts.

00:50:22After that,

00:50:24several thin smooth legs

00:50:26resembling curved needles

00:50:28also enter inside.

00:50:30All these details come together

00:50:32and transform into a strange creature

00:50:34inside the microbe.

00:50:36A diamond is fixed to one end of the screw

00:50:38and the needles' legs cling.

00:50:40All of them enter the body of the jelly.

00:50:42They connect together

00:50:44and form an army of robots.

00:50:46All these creatures come out of a small hole in the bacteria

00:50:48and put the microbe in pieces.

00:50:50You escape and find yourself in chaos.

00:50:52The little robot with a diamond

00:50:54instead of the head

00:50:56is called a bacteriophage.

00:50:58Despite their appearance, they are created by nature

00:51:00and not artificially.

00:51:02The goal of bacteriophages is to attack

00:51:04and destroy the bacteria inside.

00:51:06This is how they reproduce.

00:51:08These creatures are everywhere around us

00:51:10and control the population of microorganisms.

00:51:12When the bacteria

00:51:14multiply inside the human body,

00:51:16they leave decomposing waste.

00:51:18This waste is harmful to the body

00:51:20and must therefore be fought.

00:51:22Sometimes doctors use bacteriophages

00:51:24to help them get rid of bad microbes.

00:51:26They only attack the bacteria.

00:51:28And now,

00:51:30you see hundreds of billions of bacteriophages

00:51:32destroying billions of bacteria.

00:51:34The moving diamonds jump on the bacteria,

00:51:36plunge their heads

00:51:38and release the genetic code.

00:51:40Separate parts come together

00:51:42in new bacteriophages.

00:51:44You continue your journey

00:51:46and take some diamonds with you, just in case.

00:51:48The journey is long, but after a few weeks,

00:51:50you finally reach the palace.

00:51:52In the normal course of time,

00:51:54it takes an hour.

00:51:56You are exhausted and there is still a long way to go

00:51:58to reach the top.

00:52:00The palace is so high that you can't see the top.

00:52:02You can't sleep because you could

00:52:04wake up inside a microbe.

00:52:06There are still a lot of bacteriophages in the area,

00:52:08but you don't want to take any risks.

00:52:10A deafening noise

00:52:12shakes the air.

00:52:14It's like a plane turbine

00:52:16spinning right next to your ear.

00:52:18You open your eyes.

00:52:20A creature the size of a city

00:52:22lands on the carpet from the sky.

00:52:24It beats wings and makes this noise.

00:52:26The wings create a hurricane.

00:52:28You grab the hairs of the carpet

00:52:30to avoid being carried away by the wind.

00:52:32One of its legs looks like a big skyscraper.

00:52:34You realize that it's a fly.

00:52:36It's your chance to reach the palace.

00:52:38Big orange eyes

00:52:40divided into thousands of segments

00:52:42look like two planets.

00:52:44You climb on the tip of the fly's leg.

00:52:46The insect flies away

00:52:48and you hang on tight.

00:52:50The carpet moves away more and more.

00:52:52From up there, you see the top of the palace.

00:52:54It is so wide that you can't see the round edge.

00:52:56You let go of the fly and you fall.

00:52:58In the air, you meet millions of bacteria.

00:53:00Finally, you land on the solid surface of the palace.

00:53:02The device activates

00:53:04and you go back to your normal size.

00:53:06You were very lucky.

00:53:10You fly first class to Rome.

00:53:12Holidays, tourist visits,

00:53:14everything is going well.

00:53:16Then the pilot speaks.

00:53:18Your attention, please.

00:53:20This is the commander on board.

00:53:22The ground below us has frozen.

00:53:24We can't land.

00:53:26Everyone panics.

00:53:28The security belt signal is on.

00:53:30But no one seems to care.

00:53:32People are agitated in all directions.

00:53:34The hostesses and stewards

00:53:36try to calm everyone down

00:53:38but they are intimidated and ignored.

00:53:40Food flies everywhere.

00:53:42People empty their luggage

00:53:44frantically to find

00:53:46we don't know what.

00:53:48You look out the window

00:53:50and you see buildings falling like dominoes.

00:53:52The roads begin to look like spaghetti.

00:53:54The sea is projected into the ground.

00:53:56The mountains in the distance also collapse

00:53:58causing huge landslides.

00:54:00It really looks like ice cream.

00:54:02Your phone starts to go crazy

00:54:04with notifications of special bulletins.

00:54:06This phenomenon happens all over the world.

00:54:08But it is not a tremor of giant earth or other.

00:54:10Earth's crust has lost its hardness

00:54:12and has become soft

00:54:14like a birthday cake.

00:54:16The earth has many layers

00:54:18stacked on top of each other.

00:54:20The inner core, the outer core,

00:54:22the mantle and the crust.

00:54:24The latter is the upper layer

00:54:26on which we walk.

00:54:28When the mantle moves a little too much,

00:54:30the crust begins to move.

00:54:32This is what happens

00:54:34during an earthquake.

00:54:36The earth's crust has about 7 massive plates

00:54:38and a lot of smaller plates.

00:54:40Now they are all separated

00:54:42into millions of pieces

00:54:44as if the world were a giant cradle.

00:54:46The Eiffel Tower,

00:54:48the pyramids of Egypt,

00:54:50the Great Wall of China,

00:54:52the bridges,

00:54:54all these structures collapse.

00:54:56Years later,

00:54:58you and the rest of humanity

00:55:00are adapted to the new unstable surface of the earth.

00:55:02Your daily life now consists

00:55:04of wearing special shoes

00:55:06to help you keep your balance

00:55:08wherever you go.

00:55:10Say goodbye to high heels and sneakers.

00:55:12These boots are equipped with a special device

00:55:14that keeps you on the ground,

00:55:16a bit like a gecko climbing a wall.

00:55:18Sleeping in constant motion

00:55:20is normal,

00:55:22but it is much less comfortable

00:55:24than sleeping on a water bed.

00:55:26Imagine waking up in the middle of the night

00:55:28to have a glass of milk

00:55:30and the ground moving.

00:55:32You would fall 20 times

00:55:34before getting to the kitchen.

00:55:36Going down the stairs

00:55:38would be like a slide.

00:55:40Houses built with concrete no longer exist.

00:55:42A kind of giant bubble

00:55:44is now used as a house.

00:55:46Thanks to a special technology,

00:55:48the bubble can be stabilized

00:55:50so that it does not shake all the time.

00:55:52The foundations under your house

00:55:54oscillate with the wavy road

00:55:56so that it does not collapse.

00:55:58People rely a lot on drone technology

00:56:00to deliver food,

00:56:02supplies or the latest mobile phone.

00:56:04In fact, the entire sky

00:56:06is regularly filled with drones

00:56:08going from one place to another.

00:56:10Sports have been deeply reviewed.

00:56:12Basketball players are now

00:56:14equipped with helmets and body protection

00:56:16to avoid injury when they fall,

00:56:18which is often the case.

00:56:20Trying to dribble on a soft surface

00:56:22is almost impossible.

00:56:24A sport that survives very well

00:56:26is ice hockey,

00:56:28as well as all ice sports,

00:56:30speed skating, artistic skating, etc.

00:56:32As long as the ice is thick enough,

00:56:34no matter what happens below.

00:56:36Almost everyone relies on these bubbles

00:56:38to do anything or go anywhere.

00:56:40They can be compared to giant hamster balls

00:56:42floating on a shallow lake.

00:56:44Humans have adapted

00:56:46and no longer feel the pain of transport.

00:56:48The new economy is still based

00:56:50on trade and transport,

00:56:52but now it is mainly done

00:56:54with boats.

00:56:56There are no more big trucks on the road

00:56:58and there are no more roads.

00:57:00Helicopters have become very popular,

00:57:02but their landing can be quite dangerous.

00:57:04Everywhere in the world,

00:57:06lands float and drift.

00:57:08Before, it took millions of years,

00:57:10now it takes a few years.

00:57:12Imagine that you live in Melbourne, Australia,

00:57:14but your city is only a few months away

00:57:16from South America,

00:57:18a bit like a giant cruise ship.

00:57:20All over the planet, millions of animals

00:57:22used to migrate over enormous distances

00:57:24to find water during the dry season.

00:57:26All this is over.

00:57:28Marine life and our flying friends

00:57:30have been relatively spared.

00:57:32As the ground is still moving,

00:57:34it is impossible for the huge herds of animals

00:57:36to stay together when they cross the land.

00:57:38They try to adapt,

00:57:40but it is difficult.

00:57:42The goats of the mountains

00:57:44had evolved to adapt to a mountainous environment,

00:57:46but now the whole world

00:57:48is only a soft and flat mass.

00:57:50After putting on your boots,

00:57:52you go to see friends in the park.

00:57:54All this inside a big bubble, of course.

00:57:56When the ground collapsed

00:57:58several years ago,

00:58:00many factories exploded

00:58:02and released a lot of chemical products

00:58:04into the atmosphere,

00:58:06so it is better to stay in its bubble.

00:58:08You get in your car in the shape of a hamster ball

00:58:10and you start.

00:58:12The ground is both bumpy and gelatinous,

00:58:14but you end up getting there.

00:58:16Have you ever tried to eat or drink

00:58:18on a tangy boat?

00:58:20The sailors are used to it,

00:58:22but for most of us,

00:58:24it is very complicated.

00:58:26Now, everyone is able to manipulate

00:58:28the hot soup without spilling a single drop.

00:58:30After lunch,

00:58:32your friends decide to go out

00:58:34and explore the land outside the giant bubble.

00:58:36At first, you refuse,

00:58:38but one way or another,

00:58:40you find yourself stuck in your personal bubble car

00:58:42heading out.

00:58:44You sneak through the security,

00:58:46find a place to hide the cars

00:58:48and go out.

00:58:50Your friends and you looked ridiculous

00:58:52with their specialized boots and gas masks.

00:58:54But for nothing in the world,

00:58:56you would not want to inhale all these toxic fumes.

00:58:58You go to the place where

00:59:00once was a big city.

00:59:02The area now looks like a science fiction movie set.

00:59:04Buildings stacked on top of each other

00:59:06with nature growing all around.

00:59:08The roads that used to exist

00:59:10have been broken down.

00:59:12You walk on bricks, concrete

00:59:14and broken asphalt.

00:59:16The statues are half buried in the ground.

00:59:18Far in front of you

00:59:20is an old abandoned airport.

00:59:22You have to be careful

00:59:24to everyone of your steps.

00:59:26The ground wiggles under your feet.

00:59:28No one has come here for years.

00:59:30As you head towards the heart of the city,

00:59:32huge blocks of concrete

00:59:34separate from a fallen building.

00:59:36You do your best to jump,

00:59:38but the ground is so unstable

00:59:40that you barely make it.

00:59:42Your friends and you finally find

00:59:44the way to the city center

00:59:46and this is where you notice

00:59:48that there is a lot of water around.

00:59:50When the buildings collapsed,

00:59:52they destroyed all the water and drainage systems.

00:59:54All the water from houses,

00:59:56companies, factories

00:59:58and hundreds of farms around

01:00:00With your gecko boots,

01:00:02your friends and you climb a building

01:00:04and reach the top.

01:00:06It looks like the lost city of Atlantis.

01:00:08The buildings look like the ruins

01:00:10of an abandoned civilization.

01:00:12One of your friends gets nervous.

01:00:14Maybe it's time to go back to the bubble city.

01:00:16But you think it's better

01:00:18to keep going.

01:00:20You find a piece of floating wood

01:00:22and you make a kind of improvised raft.

01:00:24You all get on board

01:00:26and paddle through the city.

01:00:28Under the surface,

01:00:30there is a whole new ecosystem

01:00:32of plants and underwater animals.

01:00:34And not far away,

01:00:36you spot a half-immersed ship wreck.

01:00:38One of your friends suggests

01:00:40that you go there to explore it.

01:00:42When you get on it,

01:00:44the water starts to shake.

01:00:46The ground under the ship is so fragile

01:00:48that any change in pressure

01:00:50makes it sink deeper.

01:00:52You get back on the raft

01:00:54and start paddling

01:00:56to get back to where you came from.

01:00:58But the ground is extremely unstable

01:01:00and the collapsed buildings start to move.

01:01:02It's like kayaking

01:01:04on a wild river.

01:01:06But it also rains concrete.

01:01:08Once you've managed to get back

01:01:10to the bubble car,

01:01:12you and your friends decide

01:01:14it's time to go back to the giant bubble.

01:01:16But as you start to move,

01:01:18you notice that everything seems

01:01:20completely different.

01:01:22The ground has moved so much

01:01:24that everything around you looks identical,

01:01:26as if you were stuck in a giant labyrinth.

01:01:28You drive for hours.

01:01:30Is the giant bubble close?

01:01:32It's impossible to say.

01:01:34Nowhere do you hear

01:01:36a loud rumble above you.

01:01:38You look up

01:01:40and see a helicopter flying in the air.

01:01:42It descends a rope ladder

01:01:44and everyone climbs on it.

01:01:46You were lucky this time.

01:01:48There is ice everywhere,

01:01:50as far as the eye can see.

01:01:52A white desert

01:01:54covers the entrance to your cave,

01:01:56the one where you live

01:01:58with the rest of your tribe.

01:02:00Everyone is gathered around a house

01:02:02to try to warm up,

01:02:04telling stories

01:02:06about the snowstorm of the other day.

01:02:08Some run around playing,

01:02:10throwing sticks,

01:02:12everything people did to have fun

01:02:14300,000 years ago.

01:02:16You are one of the first

01:02:18Homo sapiens to have walked on Earth.

01:02:20Others sleep

01:02:22or simply rest their eyes.

01:02:24All around the cave,

01:02:26you only hear growling stomachs.

01:02:28It looks like a wild animal

01:02:30that is roaring.

01:02:32You look through the mouth of the cave

01:02:34and you see that the storm has calmed down.

01:02:36It's time to take tools

01:02:38and get out in a group.

01:02:40In the wild,

01:02:42you find a few lakes

01:02:44covered in snow

01:02:46and plants that could be edible.

01:02:48But it's not enough

01:02:50to feed the whole tribe.

01:02:52It's the ice age

01:02:54and there is not much vegetation growing.

01:02:56One of your friends

01:02:58spots large footprints in the snow.

01:03:00The hunt is open.

01:03:02You are not able to identify the animal,

01:03:04but it should be enough

01:03:06to feed everyone for a few days.

01:03:08As you plunge

01:03:10into the snowy forest,

01:03:12you hear a growling behind you.

01:03:14You hope it's your stomach,

01:03:16but you take a look behind you

01:03:18and you suddenly faint.

01:03:20An ice age is a period

01:03:22during which large layers of ice

01:03:24cover everything,

01:03:26permanently changing the Earth.

01:03:28It is partly responsible for the elevation

01:03:30and lowering of sea levels

01:03:32as well as the current layout of the continents.

01:03:34Imagine thick and monstrous layers of ice

01:03:36spread over what is today

01:03:38Canada, Scandinavia,

01:03:40Russia and even South America.

01:03:42All this has led to a radical change

01:03:44in sea levels

01:03:46and a spectacular drop in temperatures

01:03:48around the world.

01:03:50And we are not talking about one single ice age.

01:03:52There have been several.

01:03:54Scientists say

01:03:56there have been five major ice ages

01:03:58throughout history,

01:04:00which have lasted millions of years.

01:04:02And we are in the middle of one of them right now.

01:04:04Relax, don't panic.

01:04:06That doesn't mean we're all going to sleep

01:04:08next to a campfire to try to warm up

01:04:10after spending the day

01:04:12looking for mammoths.

01:04:14And no, there will be no massive geological ice storm

01:04:16that will freeze everything in its path.

01:04:18Ice ages

01:04:20include warmer periods

01:04:22that go and come

01:04:24and last tens of thousands of years.

01:04:26In fact,

01:04:28billions of years ago,

01:04:30the Earth was a giant ball of lifeless snow.

01:04:32And the sun of the time

01:04:34was also just a pretty little ball

01:04:36of incandescent gas,

01:04:38without enough heat to melt all this ice.

01:04:40But as the sun became bigger

01:04:42and hotter,

01:04:44the Earth's ice slowly melted,

01:04:46creating the green and blue sphere

01:04:48we know today.

01:04:50We live in the Quaternary Ice Age,

01:04:52which has lasted for 2.6 million years.

01:04:54And it's not over.

01:04:56Some animals have thrived

01:04:58during this last ice age,

01:05:00such as whales and sharks.

01:05:02They have been at the top of the food chain

01:05:04for thousands of years.

01:05:06Below them are seals,

01:05:08some species of fish,

01:05:10otters,

01:05:12and even tiny planktons.

01:05:14And above, on the cold surface,

01:05:16mammals had to grow thick fur

01:05:18and hair to stay warm.

01:05:20The ancient mammoths, rhinoceros and bison,

01:05:22were known to have thick covers on them.

01:05:24They were superb.

01:05:26They were herbivores

01:05:28and ate small shrubs and grass

01:05:30they could find.

01:05:32Temperatures began to rise

01:05:34and most of these animals went extinct.

01:05:36Those that remained evolved

01:05:38to become elephants, hippos

01:05:40and current rhinoceros.

01:05:44You wake up from your sleep

01:05:46and find yourself facing a creature

01:05:48that looks a bit like a lynx of modern times,

01:05:50except that it is much

01:05:52bigger and hairier.

01:05:54It's a smilodon,

01:05:56an epic version of the saber-toothed tiger,

01:05:58with a mean look.

01:06:00It is about the same size

01:06:02as a male lion

01:06:04and has two front claws

01:06:06that make you think twice

01:06:08before leaving the cave.

01:06:10They look scary,

01:06:12but scientists think

01:06:14their bite was not as powerful

01:06:16as that of tigers or current lions.

01:06:18What made them tough

01:06:20was their giant forelegs

01:06:22that they used to tear down

01:06:24anyone who came to get them.

01:06:26They were even able

01:06:28to wake you up next to this kitten.

01:06:30They stare at you,

01:06:32ready to jump,

01:06:34but you and your friends

01:06:36stay calm and move back slowly.

01:06:38You have the great idea

01:06:40to throw a stone to distract it

01:06:42and then run.

01:06:44Nowadays, it is almost impossible

01:06:46for a human to escape a lion or a tiger,

01:06:48but humans of the time

01:06:50were much more in shape.

01:06:52Once the danger is over,

01:06:54everyone continues to look for food.

01:06:56But no one has found anything

01:06:58to bring back to the cave.

01:07:00Suddenly, you smell a burning smell.

01:07:02In the distance,

01:07:04you see a thin column of smoke

01:07:06rising in the sky.

01:07:08In another camp,

01:07:10your friends and you

01:07:12look at each other

01:07:14and approach the smoke

01:07:16with caution.

01:07:18Homo sapiens appeared

01:07:20about 200,000 to 300,000 years ago,

01:07:22but human history

01:07:24shows that some hominids already existed.

01:07:26They left their chimpanzee ancestors

01:07:28in the jungle

01:07:30and began to wander in their occupation.

01:07:32And this did not happen only once.

01:07:34Over the millions of years that followed,

01:07:36there were more than

01:07:3820 different human species.

01:07:40Some are our ancestors,

01:07:42others were the branches

01:07:44of a completely different branch.

01:07:46Some were very small,

01:07:48others better adapted to hot or cold weather.

01:07:50Before even realizing it,

01:07:52you see a group of Neanderthal men

01:07:54preparing meat

01:07:56and sharpening their tools.

01:07:58The Neanderthals were the first

01:08:00to migrate to Europe.

01:08:02Scientists think they were there

01:08:0440,000 to 400,000 years ago.

01:08:06They occupied all the areas

01:08:08between Europe and Asia,

01:08:10while Homo sapiens,

01:08:12that is, our ancestor,

01:08:14was still all the way down in Africa.

01:08:16You enter their camp

01:08:18and see their differences.

01:08:20They are hairy

01:08:22and look a little different.

01:08:24But there are similarities,

01:08:26like flat teeth for chewing and chewing,

01:08:28and voluminous skulls to shelter their big brains.

01:08:30They even wear clothes like you.

01:08:32According to archaeologists,

01:08:34they lived in shelters

01:08:36and made tools with stones,

01:08:38sticks and bones.

01:08:40They welcome you inside

01:08:42and give you an exclusive guided tour.

01:08:44You officially meet another human species.

01:08:46They take you to the bottom of their caves

01:08:48and show you some of their rough paintings.

01:08:50They were the first artists of their time.

01:08:52Many of their galleries

01:08:54still exist today,

01:08:56like the one found in Spain.

01:08:58You know their style,

01:09:00minimalist wax paintings,

01:09:02a large handprint.

01:09:04They also tried to make jewels.

01:09:06They made necklaces

01:09:08with eagle's and bird's feathers.

01:09:10They were also probably

01:09:12the first to exploit the power of fire.

01:09:14Did they discover it when a lightning struck a tree,

01:09:16or when one of them

01:09:18hit a stone on another stone

01:09:20creating a spark?

01:09:22No one really knows.

01:09:24But they were able to reproduce it

01:09:26and use it to warm up,

01:09:28cook food,

01:09:30see in the dark and protect themselves.

01:09:32After this great visit,

01:09:34you stay around the campfire to warm up.

01:09:36They even offer you some extra clothes

01:09:38for the return trip,

01:09:40mainly mammoth fur coats.

01:09:42If only you could talk to each other!

01:09:44It would be great!

01:09:46But night falls,

01:09:48and you have to go back to your tribe.

01:09:50You say goodbye,

01:09:52and thank them for teaching you

01:09:54how to draw a deer

01:09:56and for the food they gave you.

01:09:58The Ice Age was important

01:10:00for the development of modern Homo sapiens.

01:10:02Because of the extreme cold

01:10:04and other difficult conditions,

01:10:06they had to adapt to survive

01:10:08and show themselves as intelligent as innovative.

01:10:10They developed advanced tools

01:10:12and even used bone needles

01:10:14to sew warm clothes.

01:10:16They may have organized

01:10:18the very first fashion show.

01:10:20When the climate

01:10:22began to warm up,

01:10:24they developed agricultural techniques

01:10:26to ensure their subsistence

01:10:28and mainly settled

01:10:30near large stretches of water

01:10:32such as rivers or lakes,

01:10:34while others chose to be

01:10:36near seas and oceans.

01:10:38Fast forward a few hundred

01:10:40thousand years,

01:10:42and here we are.

01:10:44Here we go again.

01:10:46You jump out of your bed,

01:10:48prepare your bag for work

01:10:50while swallowing your coffee.

01:10:52Your alarm clock has forgotten to ring again,

01:10:54so you had to hurry

01:10:56all morning.

01:10:58When you are about to leave,

01:11:00you hear a scream coming from the outside.

01:11:02You rush into the street.

01:11:04Maybe someone needs help.

01:11:06But nothing seems abnormal to you.

01:11:08All you see is a woman looking upset

01:11:10who is frantically tapping her phone.

01:11:12She suddenly turns to you

01:11:14and says something about the battery,

01:11:16but she is so angry

01:11:18that it is difficult to understand.

01:11:20She may have missed an important call

01:11:22and needs a charger.

01:11:24You offer your help and go home

01:11:26in a hurry to bring her yours.

01:11:28When you unplug your phone,

01:11:30you notice that it no longer has a battery either.

01:11:32Weird, it should have been 100%

01:11:34charged all night.

01:11:36You think about your alarm clock that did not work

01:11:38and you wonder if there is a power outage

01:11:40in the neighborhood or something like that.

01:11:42You are even more worried

01:11:44when you check your laptop.

01:11:46It does not turn on either.

01:11:48How are you going to do your presentation at work today?

01:11:50Oops!

01:11:52You realize that the woman outside

01:11:54is probably still waiting for the charger.

01:11:56You rush outside again,

01:11:58but she's gone.

01:12:00The street now looks like a disaster movie set.

01:12:02She is full of angry pedestrians

01:12:04and confused.

01:12:06You manage to catch a few bits of conversation

01:12:08about electricity and batteries,

01:12:10and it is clear that something

01:12:12went very wrong.

01:12:14Your neighbor in front of you is on the ground

01:12:16holding his knee and rubbing his head,

01:12:18while his hoverboard

01:12:20is a few meters above the ground.

01:12:22It looks like he made a big fall.

01:12:24You wonder why everything is so bad

01:12:26for everyone.

01:12:28The man who usually delivers your newspaper

01:12:30stops his bike next to you.

01:12:32He is so angry that he barely manages

01:12:34to say a sentence.

01:12:36The battery of my bike is flat.

01:12:38I think I'm going to have to

01:12:40go up all these old streets now.

01:12:42A friend from work

01:12:44runs to you

01:12:46saying that his car has stopped.

01:12:48You try to help him,

01:12:50but no, the battery is really flat.

01:12:52It looks like everyone

01:12:54has the same problem,

01:12:56and the streets are completely deserted.

01:12:58You also try your car,

01:13:00but it does not work either.

01:13:02While you were immersed in your thoughts,

01:13:04thinking about how to continue

01:13:06your day without your car,

01:13:08a huge piece of metal falls from the sky

01:13:10and explodes into a thousand pieces.

01:13:12A drone.

01:13:14The street is engulfed by fire,

01:13:16so you and your friend

01:13:18run and take refuge inside.

01:13:20At least it looks like

01:13:22you no longer have to worry about

01:13:24going to work today.

01:13:26Your friend tells you

01:13:28that none of his electronic devices

01:13:30work, so you run to your house

01:13:32to check yours.

01:13:34You go to your bathroom

01:13:36and it's the washing machine.

01:13:38No.

01:13:40The toothbrush?

01:13:42No.

01:13:44And the great remote-controlled car

01:13:46you got for your 12th birthday?

01:13:48You look under the bed.

01:13:50Yes, the car is there.

01:13:52And a lot of dust too.

01:13:54You take out a bunch of garden lights.

01:13:56Hmm.

01:13:58What will the parties look like if they don't work?

01:14:00You feel uncomfortable

01:14:02thinking that the smoke detector

01:14:04won't work anymore.

01:14:06How will you know if one of your devices

01:14:08doesn't work and starts a fire?

01:14:10At least most of them won't work

01:14:12enough to start a fire now.

01:14:14It's time to check

01:14:16the most important thing,

01:14:18the television.

01:14:20You take the remote and, as expected, nothing.

01:14:22You wonder if there is at least a way

01:14:24to turn it on without the remote.

01:14:26After looking for the button for a while,

01:14:28you turn it on.

01:14:30You can't understand why only some things

01:14:32seem to work.

01:14:34The news channels all talk about the same thing.

01:14:36Apparently, all the batteries

01:14:38in the world have stopped working.

01:14:40This explains why the television

01:14:42works well.

01:14:44All the channels broadcast emergency news

01:14:46about chaotic traffic

01:14:48problems and people

01:14:50being rescued by their broken devices.

01:14:52You knock on your door

01:14:54and realize that the intercom

01:14:56doesn't ring anymore.

01:14:58Which is a good thing, by the way.

01:15:00Now you don't even need

01:15:02to pretend not to be home

01:15:04when this annoying neighbor comes to visit you.

01:15:06Speaking of neighbors,

01:15:08with a little luck, his guitar amplifier

01:15:10won't work anymore either.

01:15:12You may finally be able to have a good time on Saturday morning.

01:15:14Oh no,

01:15:16your new wireless headphones will be useless now.

01:15:18You still have to pay for them for a few months

01:15:20and you won't even be able to use them.

01:15:22Another of your friends,

01:15:24Ryan, is at the door.

01:15:26Fortunately, he's a little genius,

01:15:28so he may be able to help you

01:15:30understand what happened.

01:15:32It makes you a little scared when he tells you

01:15:34how bad things are going in the world.

01:15:36Batteries are very important

01:15:38for our society.

01:15:40Most of the technologies we use need them

01:15:42to work, but we rarely

01:15:44pay attention to them.

01:15:46Until our television remote

01:15:48stops working.

01:15:50Ryan begins to explain to you that the first battery

01:15:52was invented at the beginning of the 19th century.

01:15:54It stores the chemical energy

01:15:56which is converted into electricity

01:15:58that we use to power objects.

01:16:00You interrupt him.

01:16:02Why would you need to know that?

01:16:04How can you make your phone work again?

01:16:06He shakes his head.

01:16:08Apparently, scientists from all over the world

01:16:10are looking at the problem.

01:16:12But it seems that all the batteries

01:16:14have completely stopped working

01:16:16and they don't know why.

01:16:18The batteries we use

01:16:20most often are lithium-ion batteries,

01:16:22the ones we find in smartphones

01:16:24and laptops.

01:16:26They can be easily recharged

01:16:28and provide a fluid and reliable

01:16:30electricity supply.

01:16:32But not anymore.

01:16:34They're just pieces of useless metal.

01:16:36Rechargeable batteries are also useless.

01:16:38And now all the batteries have stopped working.

01:16:40There is no longer any way to store energy.

01:16:42Ryan seems frightened and broken.

01:16:44It seems that the world is heading

01:16:46back to the 19th century.

01:16:48You thought that everything was going to be fine.

01:16:50But you begin to understand

01:16:52how much the world is going to change

01:16:54without any way to store energy.

01:16:56You understand why Ryan

01:16:58seems so desperate

01:17:00and your face begins to pale.

01:17:02What are people going to do now?

01:17:04No connected watches, tablets,

01:17:06laptops, calculators.

01:17:08Will we have to memorize phone numbers

01:17:10or learn how many make 14 or 6?

01:17:12How will we know what time it is?

01:17:14Who will wake us up in the morning?

01:17:16At least without a smartphone,

01:17:18it will be much easier to go to bed early.

01:17:20Will people now have to get up

01:17:22from the couch every time

01:17:24they want to turn on their TV?

01:17:26Will they have to socialize without their phone

01:17:28when they are sitting in bars?

01:17:30It will no longer be possible to transport

01:17:32your computer and work on the move.

01:17:34You will no longer be able to write things

01:17:36on a Word document.

01:17:38You will have to get used to writing

01:17:40instead of typing.

01:17:42You have not seen a pen, paper since high school.

01:17:44Oh no!

01:17:46You will have to start reading books again.

01:17:48There will not be much else to do.

01:17:50Your e-reader is no longer an option.

01:17:52So you will have to consider

01:17:54buying real books.

01:17:56It could cost a lot.

01:17:58People will have to enjoy every moment

01:18:00because they will no longer be able

01:18:02to take pictures of anything.

01:18:04There will be no more scooters

01:18:06or electric cars.

01:18:08Electric cars will not be a great help either.

01:18:10Well, it's not as if you could afford one,

01:18:12but still, it was good to know

01:18:14that some people could afford one.

01:18:16What kind of cars

01:18:18will companies make now?

01:18:20Even boats have parts

01:18:22loaded on batteries,

01:18:24so they could also prove useless now.

01:18:26You may see the return

01:18:28of giant wooden galleons,

01:18:30like the ones pirates sailed on.

01:18:32And what about planes?

01:18:34Don't they need batteries too?

01:18:36It looks like this trip abroad

01:18:38will have to stay on your list for a long time.

01:18:40No more listening to music

01:18:42when you are in public transport.

01:18:44Are you going to have to

01:18:46talk to people now?

01:18:48What about social media?

01:18:50You will no longer be able to waste time

01:18:52scrolling through your feed.

01:18:54How will you be able to go to work again?

01:18:56Without a car, you will have to run

01:18:58miles every day and get up early.

01:19:00You leave yourself a note

01:19:02to see how to get a horse

01:19:04and a cart.

01:19:06And you will have to remember

01:19:08in which order they go.

01:19:10Think about it.

01:19:12Yes, today was the day

01:19:14the batteries went out.

01:19:16It's time to get new habits

01:19:18or revive some of those old habits

01:19:20forgotten for a long time.

01:19:22You spend eight minutes

01:19:24of each of your days in the shower.

01:19:26In any case, it's the average.

01:19:28That's about six months

01:19:30with about 11 bottles of shower gel

01:19:32or 30 soaps per year.

01:19:34You also use a volume of water

01:19:36that would be enough to water

01:19:38more than 98 football fields.

01:19:40Not wanting to waste so much time

01:19:42and money, you decide to stick to water

01:19:44and stop using cleaning products.

01:19:46However, you will continue

01:19:48to wash your hands with a basic soap

01:19:50to stay in good health.

01:19:52You do your research and you discover

01:19:54that 80% of all these bad bacteria

01:19:56that cause bad smells

01:19:58are caused by water.

01:20:00You don't believe it, but you put away your soap,

01:20:02your shower gel and your body milk

01:20:04and you go to bed.

01:20:06On the first day of the experiment,

01:20:08you wake up as usual, brush your teeth,

01:20:10soak yourself with nothing but water

01:20:12and put an organic deodorant.

01:20:14You just gained seven minutes

01:20:16and you used this time to enjoy a cup of coffee.

01:20:18You arrive at the office

01:20:20and ask your friend Sam to sniff you

01:20:22just to be sure.

01:20:24He looks at you like you're crazy.

01:20:26Sam doesn't notice any difference.

01:20:28Triumphant, you go home and repeat your shower

01:20:30without soap the next morning.

01:20:32Your hair is starting to get a little greasy

01:20:34because you washed it two days ago.

01:20:36You decide to give them one more day

01:20:38and gradually lengthen the intervals

01:20:40between washes.

01:20:42In the evening, you feel the temptation

01:20:44to catch a shower gel.

01:20:46You really want to take a cold shower,

01:20:48but you realize that you need higher temperatures

01:20:50to fight these bacteria.

01:20:52Day after day, you get used to these showers

01:20:54You go to bed and you see in your dreams

01:20:56the soap and body milk reaching out

01:20:58to you and begging you to find them.

01:21:00The third day of the experiment,

01:21:02you wash your hair

01:21:04only with water for the first time.

01:21:06Before doing it, you rub your scalp

01:21:08to spread the natural oils.

01:21:10Then you brush your hair in sections

01:21:12to pull the oils from the roots to the tips.

01:21:14You brush them well

01:21:16to get rid of knots

01:21:18and only then do you wash them in warm water.

01:21:20You let them dry

01:21:22until they look as clean as after a shampoo.

01:21:24The rest of your body doesn't look as clean.

01:21:26On the sixth day,

01:21:28you feel like your skin is greasy and dry at the same time.

01:21:30Your abandoned soap triumphs.

01:21:32You reach out to it

01:21:34on the verge of abandonment

01:21:36when suddenly your TV lights up on its own.

01:21:38It's an entire show on how to stay clean

01:21:40without using soap.

01:21:42We learn that the Romans of the first century

01:21:44used to immerse themselves for two hours

01:21:46in baths of different temperatures,

01:21:48scrub themselves and apply oils

01:21:50to feel clean.

01:21:52For the French aristocrats of the 17th century,

01:21:54changing shirts every day

01:21:56and putting water on their hands was enough.

01:21:58It's a bit of a question of psychology.

01:22:00You have to get used to your new sense of cleanliness.

01:22:02The smell of soap and shower gel

01:22:04used to be your smell of cleanliness.

01:22:06Now you have your own natural smell.

01:22:08And it doesn't matter

01:22:10if it's not vanilla or almond.

01:22:12You also learn

01:22:14that the absence of soap

01:22:16doesn't stop you from scrubbing.

01:22:18If you're happy to stay under running water,

01:22:20you won't make bacteria disappear.

01:22:22But you can use a toilet glove,

01:22:24a scrubbing sponge,

01:22:26a body brush or whatever suits you.

01:22:28When you scrub yourself,

01:22:30you remove the upper layer of skin cells

01:22:32that you no longer need.

01:22:34You tell yourself that you're cleaner than ever.

01:22:36You come out of the shower and after 15 minutes

01:22:38you feel that your skin is smooth and flawless.

01:22:40You also notice that your skin

01:22:42has this soft and creamy glow

01:22:44like in an ad for a body lotion.

01:22:46The chemical products in the soap

01:22:48are very dehydrating.

01:22:50They remove the protective oils from your skin.

01:22:52This disrupts the balance of oils

01:22:54in your fragile ecosystem

01:22:56and turns your skin into a dry and cracked desert.

01:22:58Water helps to restore this balance.

01:23:00You go to work

01:23:02and ask Sam if he noticed any changes in your smell.

01:23:04Once again, he doesn't really understand.

01:23:06So you explain your experience to him.

01:23:08He looks at you with approval

01:23:10and, surprisingly, also shares some knowledge about the subject.

01:23:12First of all,

01:23:14sanitation is important.

01:23:16If you work with dangerous chemicals

01:23:18in a farm, as a gardener or a construction worker,

01:23:20and you come into contact with dust,

01:23:22pollen and allergens,

01:23:24you have to take a shower every day

01:23:26and with soap.

01:23:28It's the same for athletes, personal coaches

01:23:30and fitness instructors.

01:23:32Unless you do one of these jobs,

01:23:34you can very well be content with water

01:23:36or not take a shower at all for days.

01:23:38In addition, you save a lot of energy

01:23:40when you drive

01:23:42and that's why people in the past

01:23:44needed to take a shower more often than you.

01:23:46Secondly, your genetic code

01:23:48also plays a role.

01:23:50Your sudoriparous glands could be more active

01:23:52than your neighbor's

01:23:54and you could be more likely to feel bad.

01:23:56Your colleague Julie hears the discussion

01:23:58and adds that the clothes you wear

01:24:00can also have an influence.

01:24:02Cotton lets your skin breathe better than polyester.

01:24:04It also lets enough moisture escape

01:24:06so that you don't feel bad.

01:24:08Julie also reveals her secret.

01:24:10She only takes showers with water

01:24:12for a month.

01:24:14She always wears a long-sleeved shirt

01:24:16and a pair of jeans at the office

01:24:18and she is perfectly fine.

01:24:20Her skin doesn't really get dirty.

01:24:22She also admits that she has feet

01:24:24that smell bad.

01:24:26As long as she wears shoes,

01:24:28like most people at the office,

01:24:30no one ever notices.

01:24:32It's been 7 days since you washed

01:24:34your hair with warm water.

01:24:36They are a little greasy or touched

01:24:38but they stay on your scalp.

01:24:40You re-train them to produce enough

01:24:42so that your hair doesn't get greasy

01:24:44as fast as before.

01:24:46You repeat the hair ritual with massage,

01:24:48pre-treatment, brushing

01:24:50and washing.

01:24:52You continue the experience

01:24:54and at the beginning of the third week

01:24:56you realize that you can perfectly live

01:24:58without soap or shampoo in the bathroom.

01:25:00You go to work, you see your friends

01:25:02and no one notices a difference.

01:25:04You learn to accept that your natural smell

01:25:06is not that of flowers

01:25:08but not that of dirty socks either.

01:25:10You also realize that the soap

01:25:12does not deodorize but leaves a thin

01:25:14layer of perfume.

01:25:16It makes you feel fresh and clean

01:25:18but then it relaunches the problem

01:25:20that it has just solved.

01:25:22Your hair feels better than ever.

01:25:24They are perfectly hydrated, soft

01:25:26and even voluminous.

01:25:28They feel fresh and look clean

01:25:30so that no one could say

01:25:32that you no longer use shampoo.

01:25:34They also dry faster

01:25:36and are easier to style.

01:25:38You save the money that was used

01:25:40to buy shampoo, soap, shower gels

01:25:42and body milk.

01:25:44And above all, you now have more time

01:25:46in the morning and before going to bed.

01:25:48You see that your skin is healthier than ever

01:25:50and you decide to give it

01:25:52soap breaks from time to time.

01:25:54If you stayed in this mode forever,

01:25:56you could have problems with the remaining

01:25:5820% of bacteria that cannot be eliminated

01:26:00only by water.

01:26:02The resistance is particularly strong

01:26:04in the warm and humid areas of your body.

01:26:06When you accept to use

01:26:08less water, you can try

01:26:10one of the alternatives to soap.

01:26:12You can make your own natural gum

01:26:14from the ingredients you have in the kitchen.

01:26:16Oat flakes, honey

01:26:18and natural yogurt mix well,

01:26:20as well as avocado oil, honey

01:26:22and sugar.

01:26:24You can't rub your face with it

01:26:26because the skin is more delicate.

01:26:28You can also try oil-based cleansers

01:26:30and old skin cells.

01:26:32They do not disturb the balance of oils

01:26:34when you put them on before taking a shower.

01:26:36Cinnamon and clove

01:26:38are both famous for their antibacterial properties.

01:26:40Their oils are therefore

01:26:42perfect for this.

01:26:44Honey is excellent for keeping your body

01:26:46healthy and preventing the growth

01:26:48of bacteria.

01:26:50You can use it as a natural cleanser

01:26:52with only one ingredient.

01:26:54Cider vinegar is also an excellent

01:26:56natural toning for the skin.

01:26:58If you want to use soap,

01:27:00choose the natural options.

01:27:02Check if it contains glycerin.

01:27:04It is a plant-based cleanser

01:27:06that retains all the useful moisture

01:27:08in Tapo's natural protective barrier.

01:27:10Carite butter and coconut butter

01:27:12are used in hypoallergenic soaps.

01:27:14Lemon, rose, lavender

01:27:16and cedar wood oils

01:27:18are often added to perfumed

01:27:20and healthy soaps.

01:27:22Coconut oil and almond oil

01:27:24are also excellent moisturizers.

01:27:28Do you see Jupiter over there in the distance?

01:27:30Yes, look how it floats in space

01:27:32among its friends, the planets.

01:27:34You see Mars, red, orange

01:27:36and Jupiter with its asteroid belt.

01:27:38Even the tiny Pluto is there.

01:27:40All these planets keep their distances

01:27:42between them,

01:27:44each evolving on its own orbit.

01:27:46They are not very sociable, you know,

01:27:48but it's a good thing.

01:27:50They would only be a nuisance

01:27:52if they got to hang out a little too close.

01:27:54But although they are not unique,

01:27:56Jupiter is the only planet with life

01:27:58that we know of.

01:28:00And we even know why.

01:28:02It's because it was lucky enough

01:28:04to appear at the best place

01:28:06in our solar system,

01:28:08in the golden loop area.

01:28:10Scientists say that the key ingredient

01:28:12of life is water.

01:28:14But there is water on Mercury.

01:28:16This planet has deposits of ice water

01:28:18at its poles south and north,

01:28:20but only because these places

01:28:22never see the light.

01:28:24Mercury is way too close to the Sun.

01:28:26Pluto also has a little water.

01:28:28Astronomers even think

01:28:30that the dwarf planet

01:28:32could be made up of 30% water.

01:28:34But it is frozen.

01:28:36Unlike Mercury,

01:28:38Pluto is too far from the Sun.

01:28:40That's why all its water

01:28:42is in the form of ice.

01:28:44But the Earth is floating in this perfect region

01:28:46called the habitable zone.

01:28:48It has the right temperature

01:28:50for the water to remain liquid

01:28:52and for it to flourish.

01:28:54But what would happen

01:28:56if the Earth was the only planet

01:28:58in the solar system?

01:29:00No more Mars, no more Jupiter,

01:29:02no more Mercury, no more Venus.

01:29:04Things could have happened

01:29:06a little differently

01:29:08from what we are used to.

01:29:10Do you remember this massive asteroid

01:29:12that hit the Earth

01:29:14about 66 million years ago?

01:29:16Yes, the bad rock.

01:29:18Well, without Jupiter

01:29:20some of them would be as big

01:29:22as the one that caused all this

01:29:24bad luck to the dinosaurs.

01:29:26These rocks would float in space

01:29:28without anything or anyone

01:29:30to stop them.

01:29:32And if the Earth was the only planet

01:29:34in the area,

01:29:36it would be their only pain reliever.

01:29:38But that's not all.

01:29:40Look at all this huge space

01:29:42that the Earth would have for itself.

01:29:44This means that our planet

01:29:46would have the opportunity

01:29:48to flourish.

01:29:50Let's suppose that the Earth

01:29:52starts to move away from the Sun.

01:29:54It would soon be too cold on the planet.

01:29:56Imagine a place where the Sun

01:29:58no longer shines, dark and cold,

01:30:00covered in ice and snow all year long.

01:30:02This is how our Earth would look

01:30:04if it moved away from the Sun.

01:30:06If this were to happen,

01:30:08our cities would look very different.

01:30:10For now, the Earth is full of life.

01:30:12Go to any park

01:30:14and you will see green trees

01:30:16and grass everywhere.

01:30:18There will be people walking,

01:30:20sitting on benches and enjoying the sun.

01:30:22You will certainly see someone

01:30:24playing football or frisbee.

01:30:26On the lawns of the park,

01:30:28people will relax on blankets

01:30:30while getting tanned.

01:30:32Some people will be reading,

01:30:34quiet and happy.

01:30:36But let's go back to space.

01:30:38Here is the Earth again.

01:30:40Our planet is still in its favorite place.

01:30:42That's why life is so beautiful.

01:30:44Wait a minute. Is it moving?

01:30:46Our planet has moved away from the Sun.

01:30:48Has that changed things on its surface?

01:30:50It seems a little bluer now.

01:30:52Over there,

01:30:54the golden California

01:30:56has become a little dull.

01:30:58It is even frankly dull and dark.

01:31:00A bit like everywhere else on Earth.

01:31:02New York is covered in ice.

01:31:04Even in the hottest places,

01:31:06temperatures are now below zero,

01:31:08including in places like the Bahamas.

01:31:10After a while,

01:31:12liquid water turns into ice.

01:31:14The oceans now look like

01:31:16huge ice skates.

01:31:18Except that there is no one to skate

01:31:20because the planet has become

01:31:22too cold to shelter life.

01:31:24What if, instead of moving away from the Sun,

01:31:26the Earth got closer,

01:31:28with people still on it?

01:31:30Wow! The temperatures would be

01:31:32delirious, far too high

01:31:34to be bearable.

01:31:36The climate would not stop warming up.

01:31:38Natural disasters would become more frequent.

01:31:40Hurricanes and floods

01:31:42would now be commonplace on Earth.

01:31:44And very soon,

01:31:46the planet would be too hot

01:31:48for people to live there.

01:31:50Particles from the Sun

01:31:52would pose a considerable threat.

01:31:54The atmosphere would no longer protect

01:31:56the Earth from solar radiation.

01:31:58This shield would be increasingly weak.

01:32:00There would be no more liquid water anywhere,

01:32:02perhaps only in underground deposits.

01:32:04The Earth would look a bit like Mars,

01:32:06all rocky and sterile.

01:32:08The Mississippi would dry up

01:32:10and we would find a huge canyon in its place.

01:32:12The oceans would also have

01:32:14all disappeared.

01:32:16At present, the Marianas Fault

01:32:18is the deepest known place on Earth.

01:32:20It is incredibly difficult

01:32:22to reach its bottom

01:32:24due to the immense pressure that reigns there.

01:32:26But if there was no more water,

01:32:28it would be quite possible to travel

01:32:30to this place.

01:32:32We would discover new secrets,

01:32:34provided, of course,

01:32:36the presence of people in this drought and this heat.

01:32:38In other words,

01:32:40if we explored the Earth

01:32:42after it got closer to the Sun,

01:32:44we would find it very different

01:32:46from what it is today.

01:32:48But what would happen

01:32:50if the Earth did not move at all

01:32:52and everything remained the same?

01:32:54The only difference is that

01:32:56there would be no other planets around us.

01:32:58This would change the way

01:33:00we explore space.

01:33:02Of course, there would still be

01:33:04space telescopes,

01:33:06but there would be no celestial body

01:33:08close enough for us to do expeditions.

01:33:10This would also affect our future.

01:33:12If we had no desire

01:33:14or possibility to go into space,

01:33:16we would invest in our planet.

01:33:18We would build air cities

01:33:20instead of looking for other planets to colonize.

01:33:22Today,

01:33:24if you have a telescope,

01:33:26you can see distant stars

01:33:28and other planets.

01:33:30The more efficient the telescope is,

01:33:32the more stars you can see.

01:33:34But if there were no other planets,

01:33:36looking at space would not be as captivating.

01:33:38The stars would still be visible

01:33:40and you could even see one or two meteoroids.

01:33:42And of course you would see the Moon,

01:33:44but that's about it.

01:33:46Space agencies would focus

01:33:48especially on Earth's safety,

01:33:50mainly because asteroids

01:33:52would become frequent visitors.

01:33:54To protect the planet,

01:33:56our scientists would have the task

01:33:58of finding ways to get rid of them.

01:34:00A huge laser beam

01:34:02could go as far as the Moon.

01:34:04Instead of building rockets

01:34:06to explore space,

01:34:08SpaceX and NASA

01:34:10would clean asteroids.

01:34:12Humans would not even think

01:34:14of trying to contact other civilizations.

01:34:16If there were no planets similar to Earth,

01:34:18they would consider it a useless effort.

01:34:20This means

01:34:22that no radio signal

01:34:24would be sent into space.

01:34:26In February 2008,

01:34:28the Beatles' song,

01:34:30Across the Universe,

01:34:32was broadcast in space.

01:34:34This was done to celebrate

01:34:36the 40th anniversary of the song

01:34:38and the 50th anniversary of NASA.

01:34:40In the 1970s,

01:34:42we sent another radio signal into space.

01:34:44It contained some basic information

01:34:46about humans and the solar system.

01:34:48But it was more of a technological

01:34:50turn of events than an attempt

01:34:52to contact any extraterrestrial friends.

01:34:54Without planets,

01:34:56the world of science fiction

01:34:58would change as well.

01:35:00There would be no more movies

01:35:02about exploring distant space.

01:35:04No spaceship and no rocket

01:35:06would appear on the big screen.

01:35:08And since there would be no expeditions

01:35:10to other planets,

01:35:12no robots would be sent into space

01:35:14to look for signs of life

01:35:16and explore new worlds,

01:35:18like what rovers are doing on Mars right now.

01:35:20People would focus more

01:35:22on their own planet.

01:35:24New technologies

01:35:26would allow us to dig

01:35:28much, much deeper,

01:35:30up to the Earth's crust

01:35:32and even further.

01:35:34A trip to the heart of the planet,

01:35:36you might say.

01:35:38Instead of astronauts,

01:35:40we would have underground explorers.

01:35:42They might be called the Terplorators.

01:35:44New drilling technologies

01:35:46would be invented

01:35:48to make the process more efficient.

01:35:50There would be new types of vehicles.

01:35:52We would be the explorers

01:35:54of the enormous underground pressure.

01:35:56By exploring the world

01:35:58under the Earth's surface,

01:36:00we would probably find

01:36:02absolutely new forms of life.

01:36:04They would be mysterious creatures

01:36:06that evolved to survive

01:36:08in the darkness

01:36:10at extreme temperatures

01:36:12with very little food.

01:36:14This would probably help us

01:36:16to better understand

01:36:18our beautiful planet.

01:36:20The weather is getting hotter and hotter.

01:36:22It's like going into an oven.

01:36:24And the sand is also extremely hot,

01:36:26to the point that your rubber shoes

01:36:28start to melt.

01:36:30The ocean has just turned into boiling lava.

01:36:32You start running towards the inside of the Earth

01:36:34and you see people running like crazy

01:36:36in all directions.

01:36:38In fact, the lava is made of molten rocks

01:36:40coming from the depths of the Earth.

01:36:42In the middle of our planet,

01:36:44at a distance equivalent to that

01:36:46separating New York from Philadelphia,

01:36:48the heat of the core melts the rocks

01:36:50in the same way that the sun melts the ice.

01:36:52When these rocks melt,

01:36:54their temperature can reach

01:36:56around 1,200 degrees Celsius.

01:36:58But don't worry,

01:37:00this only happens very far underground

01:37:02and only in certain specific areas,

01:37:04mainly around the Atlantic Ocean.

01:37:06And these molten rocks

01:37:08only escape the ground

01:37:10if the pressure is very high.

01:37:12Then they go back to the surface

01:37:14in the form of a bubbling orange liquid

01:37:16called lava,

01:37:18usually caused by a volcano.

01:37:20But for one reason or another,

01:37:22the entire ocean has now turned into lava.

01:37:24And even if from a very far distance

01:37:26it is a beautiful spectacle,

01:37:28it is extremely dangerous.

01:37:30First of all, you can say goodbye

01:37:32to the beautiful blue waves and sea currents.

01:37:34Unlike water, lava is very thick,

01:37:36closer to the texture of peanut butter.

01:37:38And the wind can't move it.

01:37:40But that also means

01:37:42that nothing can flow or swim there.

01:37:44So even if some oceanic creatures

01:37:46managed to resist the super high temperatures

01:37:48of the lava,

01:37:50they couldn't live inside.

01:37:52They would be immediately submerged

01:37:54or, depending on their density,

01:37:56they would float to the surface.

01:37:58So, our sea friends and other creatures

01:38:00living in the ocean

01:38:02will have to find another place to live

01:38:04if they don't want to disappear.

01:38:06In fact, the only animals on our planet

01:38:08that could survive the heat of the lava

01:38:10are tardigrades.

01:38:12These microscopic creatures

01:38:14can survive in any extreme environment.

01:38:16In glaciers, as in the hottest volcanoes.

01:38:18They can even survive in space

01:38:20subjected to cosmic rays.

01:38:22You run away from the beach

01:38:24with all the other inhabitants of the surroundings.

01:38:26The atmosphere thickens

01:38:28and you have trouble seeing around you.

01:38:30You say to yourself,

01:38:32I should have stayed at home.

01:38:34But your house is not really safe either.

01:38:36The heat released by all this lava

01:38:38is alone intolerable for miles.

01:38:40There are no houses on the seaside

01:38:42and no swimming pools.

01:38:44You will have to go as far as possible

01:38:46from the ocean.

01:38:48Most coastal cities

01:38:50will become instantly uninhabitable.

01:38:52Especially the areas that the ocean

01:38:54borders on more than one side.

01:38:56Places like Florida, California

01:38:58and Central America

01:39:00will no longer be livable at all.

01:39:02Not to mention the islands.

01:39:04Most will become so hot

01:39:06that no animal or plant will survive.

01:39:08And all this is now transformed into lava.

01:39:10There can be no snow anywhere on Earth

01:39:12because it is now

01:39:14an incandescent ball of lava.

01:39:16Temperatures will rise so much

01:39:18that even in the most remote places

01:39:20on the coast and the highest,

01:39:22it will be as hot as a day of heatwaves

01:39:24in a desert.

01:39:26While you continue to escape the ocean,

01:39:28you tell yourself that you may be dreaming.

01:39:30But you look at your skin, which is so red.

01:39:32Even if you run for miles,

01:39:34the heat will always catch up with you.

01:39:36The oil refineries and the ships

01:39:38in the middle of the oceans

01:39:40will also encounter some problems.

01:39:42Made of metal, they will simply turn red

01:39:44and melt in contact with the boiling lava.

01:39:46And even if they do not melt,

01:39:48it is better to hope that no one

01:39:50is on board.

01:39:52But in such a situation, a massive evacuation

01:39:54would take place.

01:39:56Meanwhile, in the North and South Pole,

01:39:58where the planet is the coldest,

01:40:00all the ice covering the ocean

01:40:02starts to melt instantly.

01:40:04It solidifies to form black and rocky

01:40:06terrestrial masses called igneous rocks,

01:40:08whose texture is often glassy.

01:40:10When this happens,

01:40:12huge clouds of vapor and acid gas

01:40:14are released into the air, filling the sky.

01:40:16Scientists call these clouds

01:40:18the lava mist.

01:40:20A bit like when you get out of your shower

01:40:22and all the heat released

01:40:24comes into contact with the outside cold air.

01:40:26Except that this mist would cover

01:40:28all the North and South Poles

01:40:30and would be super toxic.

01:40:32And this mist can go around the world

01:40:34with a strong enough wind

01:40:36and cover almost the entire northern hemisphere.

01:40:38It could also cover the southern part,

01:40:40namely New Zealand, Argentina,

01:40:42South Africa and Australia.

01:40:44Crossing this gas by plane

01:40:46is certainly not a good idea.

01:40:48The heat emitted by the lava

01:40:50would cause significant damage to the fuselage

01:40:52and affect all the electronics of the aircraft.

01:40:54It's a good thing you found

01:40:56your oxygen tank.

01:40:58The air is barely breathable at this stage.

01:41:00You drive towards your car

01:41:02and drive away as fast as you can.

01:41:04But even your car has been damaged.

01:41:06You go to the countryside

01:41:08where the atmosphere has not yet been affected

01:41:10by the lava.

01:41:12But even here, the temperatures are rising.

01:41:14The river you used to see

01:41:16during your weekly hikes

01:41:18has dried up.

01:41:20The flora around you is losing its lush green.

01:41:22The animals have migrated to a milder climate.

01:41:24The rivers,

01:41:26as they throw themselves into the ocean,

01:41:28will be filled with rocks

01:41:30that will become glassy

01:41:32in contact with the lava,

01:41:34creating permanent natural dams.

01:41:36The rest of the water inside the land,

01:41:38like in swamps and lakes,

01:41:40will eventually evaporate over time.

01:41:42With the rise in temperatures

01:41:44and the absence of precipitation,

01:41:46the water will disappear from our planet.

01:41:48The enormous mass of water in the oceans

01:41:50plays a major role in the creation

01:41:52of clouds and precipitation.

01:41:54Without water in the atmosphere,

01:41:56the world would be nothing

01:41:58but a vast arid wasteland.

01:42:00The nights would be hot,

01:42:02and the days, even hotter.

01:42:04However, the lava will eventually cool

01:42:06in contact with the fresh air.

01:42:08So, quite quickly,

01:42:10a thin layer of black crust

01:42:12will form on the surface

01:42:14and gradually thicken over the years.

01:42:16The thicker the lava,

01:42:18the more time it takes

01:42:20to cool completely inside.

01:42:22All this will still be super hot,

01:42:24which is why many islands

01:42:26have formed.

01:42:28Like the Hawaiian Islands, for example.

01:42:30They are entirely made up of lava

01:42:32from underwater eruptions

01:42:34that dried for hundreds of thousands of years.

01:42:36Layers and layers

01:42:38of solidified lava

01:42:40have accumulated under the ocean

01:42:42until they float to the surface,

01:42:44forming islands and even mountains.

01:42:46At this very moment,

01:42:48a new terrestrial mass in Hawaii

01:42:50is being formed by an active volcano.

01:42:52I think we'll find a new island

01:42:54in about 10,000 years.

01:42:56But for the moment,

01:42:58the beautiful blue ocean

01:43:00has turned into a reddish,

01:43:02vaporous mud,

01:43:04which will soon become

01:43:06a black and compact desert.

01:43:08But don't think you can easily

01:43:10walk on this ocean.

01:43:12It could take hundreds of years

01:43:14for it to completely cool

01:43:16and turn into solid rock.

01:43:18In the meantime,

01:43:20some of the lava

01:43:22would have fallen into boiling lava.

01:43:24Some regions would even take

01:43:26thousands of years

01:43:28to solidify completely.

01:43:30The Mariana Trench,

01:43:32the deepest region of the ocean,

01:43:34is 13 km deep.

01:43:36It would take at least 5,000 years

01:43:38for the corresponding amount

01:43:40of lava to completely cool.

01:43:42There are many lava planets.

01:43:44A recently discovered planet,

01:43:46K2-141b,

01:43:48has a diameter of 2 m,

01:43:50and even more rocky.

01:43:52Yes, this planet is so hot

01:43:54that it evaporates rocks

01:43:56and makes them rain.

01:43:58Don't forget that this planet

01:44:00is much closer to the Sun

01:44:02than ours.

01:44:04Maybe these oceans

01:44:06suddenly turned into lava one day.

01:44:08Travel to the future.

01:44:10Yes, humans have managed

01:44:12to colonize Mars and the Moon.

01:44:14The end has been won

01:44:16Soon, our planet,

01:44:18I mean our planets,

01:44:20will have to face a new threat.

01:44:22The Moon too.

01:44:24Researchers have discovered that in 150 years,

01:44:26the Sun will explode

01:44:28and destroy our entire solar system.

01:44:30Damn!

01:44:32We have enough time to build

01:44:34a fleet of huge spaceships

01:44:36and evacuate everyone.

01:44:38But we don't know how to jump

01:44:40into hyperspace.

01:44:42It's been a long time since we were able

01:44:44to fly.

01:44:46The nearest livable planet

01:44:48is several million years away.

01:44:50No choice.

01:44:52All of humanity

01:44:54is embarked on huge spaceships

01:44:56and the endless journey begins.

01:44:58Several decades pass.

01:45:00We leave the solar system

01:45:02and witness the explosion of the Sun.

01:45:04There is no more light.

01:45:06Just a few small stars in the distance.

01:45:08From black to infinity

01:45:10all around.

01:45:12All ships are in automatic pilot

01:45:14and nothing can divert their trajectory.

01:45:16Even if everyone

01:45:18on board disappears,

01:45:20the ship would still reach its destination.

01:45:22On the one hand, it's positive

01:45:24because humans will be able to survive

01:45:26for millions of years.

01:45:28On the other hand,

01:45:30after all this time spent in space,

01:45:32they will be totally different.

01:45:34The passengers of the ships

01:45:36that will arrive on the new planet

01:45:38will become informed pulsating biomass

01:45:40placed in metal exoskeletons.

01:45:42That's why.

01:45:44In space,

01:45:46water and muscles become more fragile.

01:45:48There is no gravity

01:45:50and therefore no pressure is exerted

01:45:52on the body,

01:45:54which prevents it from functioning properly.

01:45:56ISS astronauts also do

01:45:58a lot of exercise

01:46:00to not lose their muscles.

01:46:02Let's go back to our story.

01:46:04There are gyms and machines

01:46:06that simulate gravity on each ship.

01:46:08To save energy,

01:46:10they are only run a few hours a day.

01:46:12Unfortunately,

01:46:14exercising is not enough.

01:46:16After 100 years,

01:46:18water becomes so fragile

01:46:20that any movement,

01:46:22even a little intense,

01:46:24can cause injuries.

01:46:26Another 100 years,

01:46:28and we can no longer stand up.

01:46:30But it's not just because of the fragile water.

01:46:32After all these years

01:46:34in weightlessness,

01:46:36gravity has already changed a lot.

01:46:38One of the big problems

01:46:40is that passengers lose the sense of balance.

01:46:42When they try to get up,

01:46:44they fall.

01:46:46The captains of the ships

01:46:48dismantled the gravity machines.

01:46:50They didn't work anyway.

01:46:52Little by little,

01:46:54all the sports equipment

01:46:56was recovered and transformed

01:46:58into spare parts for the ship.

01:47:00The lack of gravity

01:47:02not only weakened the passengers,

01:47:04but the ship needed gravity

01:47:06to stay stable.

01:47:08Without gravity,

01:47:10the vertebral discs spread out.

01:47:12Humans began to look like inflatable toys.

01:47:14All passengers were given

01:47:16mechanical arms and legs.

01:47:18They were put on and off they went.

01:47:20They tinkered with the engine,

01:47:22cleaned the rooms,

01:47:24evacuated debris in space,

01:47:26lifted an object.

01:47:28All this is impossible

01:47:30without mechanical arms and legs.

01:47:32Fortunately,

01:47:34mechanical combinations

01:47:36are becoming more and more efficient.

01:47:38Since the explosion of the sun,

01:47:40humans' sight has improved a lot.

01:47:42In ships,

01:47:44an artificial light

01:47:46that spreads vitamin D

01:47:48replaces sunlight.

01:47:50The general lack of light

01:47:52dilates the pupils of passengers.

01:47:54After a few hundred years,

01:47:56their sight really starts to decline.

01:47:58But this problem is solved

01:48:00by artificial lenses

01:48:02that accentuate light

01:48:04and prevent them from becoming completely blind.

01:48:06Ships are disinfected every day

01:48:08to prevent the multiplication

01:48:10of bacteria and microbes.

01:48:12This also means that

01:48:14the immune system of humans

01:48:16no longer has any disease to fight.

01:48:18Very soon,

01:48:20it will no longer be able to protect itself

01:48:22and a simple rum could be fatal to it.

01:48:24For now,

01:48:26no germs are detected on board.

01:48:28But what happened on the way?

01:48:30On the ship,

01:48:32there are millions of plants

01:48:34growing in special greenhouse

01:48:36thanks to water and ultraviolet light.

01:48:38The plants produce oxygen

01:48:40that is distributed throughout the ship.

01:48:42Of course,

01:48:44this is not enough for millions of people,

01:48:46but it is still a little souvenir.

01:48:48By living on spaceships,

01:48:50passengers have adapted

01:48:52and have almost stopped breathing.

01:48:54The lungs have practically disappeared

01:48:56and humans

01:48:58find other ways to assimilate oxygen.

01:49:00By water,

01:49:02by liquid oxygen tanks.

01:49:04The species is totally transformed.

01:49:06But everything is not negative.

01:49:08Genetic engineering

01:49:10makes huge progress every year.

01:49:12Real survival combinations are created.

01:49:14They give strength and speed,

01:49:16allow you to move, see,

01:49:18hear and even speak.

01:49:20Passenger voices have become so weak

01:49:22that they can only whisper.

01:49:24Fortunately,

01:49:26in the combinations, there is a microphone and amplifiers.

01:49:28Food is over.

01:49:30There are only special liquids.

01:49:32Anyway,

01:49:34the human stomach can no longer digest anything

01:49:36after all these years in space.

01:49:38A little snack for the road?

01:49:40Out of the question.

01:49:42At first,

01:49:44there were several types of space food.

01:49:46But as time went on,

01:49:48passengers forgot the taste of things.

01:49:50They stopped flavoring liquids

01:49:52and the taste buds

01:49:54stopped working.

01:49:56They lost the sense of taste.

01:49:58For some,

01:50:00this life is unbearable.

01:50:02But they still have a choice.

01:50:04They can lock themselves

01:50:06in a cryogenization capsule

01:50:08for millions of years.

01:50:10All you have to do is

01:50:12defrost when you arrive.

01:50:14But it is very risky to stay frozen

01:50:16for so long.

01:50:18It is possible that a meteor

01:50:20will hit the ship or worse.

01:50:22Passengers

01:50:24try another approach.

01:50:26They download their consciousness

01:50:28on a computer.

01:50:30It is safer and requires less energy.

01:50:32This way, when you wake up,

01:50:34you just have to move the data of your consciousness

01:50:36in a new modified human combination.

01:50:38Some people decide

01:50:40to stay awake and lead a normal life.

01:50:42Thousands of years pass

01:50:44and then millions.

01:50:46Humans are really different now.

01:50:48All their limbs are artificial

01:50:50and their exoskeletons

01:50:52are controlled by thought.

01:50:54Over time, the arms, the neck,

01:50:56the legs and the spine

01:50:58have become smaller and smaller.

01:51:00The bones crumble

01:51:02and end up dissolving.

01:51:04The eyes, nose and mouth

01:51:06disappear.

01:51:08The brain is no longer protected by the skull.

01:51:10It is just surrounded by skin.

01:51:12All that remains is thought.

01:51:14Humans are now

01:51:16powerful, ultra-powerful robots

01:51:18controlled by a small palpitating bag

01:51:20filled with brains.

01:51:22Humans have been leaving Earth

01:51:24for several million years.

01:51:26All passengers have forgotten

01:51:28that their species was born on a planet

01:51:30where there was gravity.

01:51:32The history of life on Earth

01:51:34has become a myth, a legend.

01:51:36Most of the humans on board

01:51:38think that ships are their only

01:51:40possible place of life

01:51:42and that they have never lived elsewhere.

01:51:44But when humans finally arrive

01:51:46at their destination,

01:51:48no one really wants to get on board

01:51:50or explore.

01:51:52Life on a new unknown planet

01:51:54is not very practical with its space suits.

01:51:56Gravity, air, bacteria

01:51:58and germs will take

01:52:00several billion years

01:52:02for humanity to evolve

01:52:04and get used to its new conditions.

01:52:06Fortunately, there is technology.

01:52:08At this stage, all humans are downloaded

01:52:10in new robot suits.

01:52:12Passengers can choose

01:52:14to land and make this planet

01:52:16their new home or stay there

01:52:18and live aboard the ship.

01:52:20Those who choose not to land

01:52:22leave to explore the meanders of space

01:52:24in search of new worlds.

01:52:26The others have to adapt

01:52:28to the new living conditions.

01:52:30It is very different from life on Earth.

01:52:32There is a different air density,

01:52:34different weather conditions

01:52:36and new strange chemical elements.

01:52:38It will take millions of years

01:52:40for these brain robots

01:52:42to transform.

01:52:44One day, the descendants of these humans

01:52:46will want to know their origins.

01:52:48They will build a ship

01:52:50that will allow them to travel

01:52:52in space-time.

01:52:54Their search will lead them

01:52:56to the Earth of now.

01:52:58It may seem crazy,

01:53:00but imagine that tomorrow

01:53:02someone lands in your garden

01:53:04and that it is one of your descendants

01:53:06from the future.

01:53:08Maybe they will find new planets

01:53:10on which they will decide to live.

01:53:12Their bodies will also adapt

01:53:14and transform.

01:53:16In millions of years,

01:53:18the universe will be inhabited

01:53:20by amazing creatures

01:53:22who will all have one thing in common.

01:53:24Originally, they were all humans.

01:53:26Originally.
