"Revising the Universe's Age Debate"

Explore the fascinating world of cosmology in our latest video as we delve into the Hubble constant and its implications for the age of the universe! Since the Big Bang, the universe has been expanding, but recent research led by Tamara Davis from the University of Queensland challenges long-held beliefs about this expansion rate. Discover how the Hubble parameter, once thought to be fixed, is now understood to change over time, potentially making the universe around 2 billion years younger than previously estimated.

We break down the significance of Hubble's law, which states that galaxies are receding from each other at speeds proportional to their distances, and discuss the latest findings from gravitational lensing studies. These groundbreaking results, involving collaboration from researchers across the globe, suggest a recalibrated Hubble parameter of 82 ± 8 km s Mpc, indicating a universe that may be only 11.8 billion years old.

Join us as we unpack the implications of these findings on our understanding of cosmic history and the universe's expansion. Don't miss out on this intriguing exploration of modern cosmology, the Hubble constant, and the mysteries of the universe!
