Why Protons Stay Together in the Nucleus | The Role of Mesons Explained
Curious about why protons don't repel each other in the nucleus despite having the same positive charge? It's all due to the strong nuclear force and the vital role of mesons! Mesons are the particles that mediate this force, acting like glue to keep protons and neutrons tightly bound in the nucleus. Discover how mesons work and why they are essential for the stability of atomic nuclei.

00:00I will never look at an atom the same way after learning this.
00:03How do protons, all positively charged, stick together in the nucleus?
00:08Protons are positively charged, which means they should repel each other, right?
00:12So why do they stay together in the nucleus?
00:15The answer?
00:17Nuclear force.
00:18This is one of the four fundamental forces of nature.
00:21It's incredibly powerful but acts only over tiny, tiny distances.
00:26Enter mesons, our unsung heroes.
00:29These are particles that act like glue between protons and neutrons.
00:33Mesons exchange between these particles,
00:36creating a strong attraction that overcomes the repulsive electromagnetic force.
00:41Imagine mesons as tiny messengers, zipping back and forth,
00:44keeping everything stuck together.
00:46Without them, the positively charged protons would repel each other
00:50and the nucleus would fall apart.
00:52This nuclear force, thanks to mesons,
00:54is what holds the core of every atom in the universe.
