Did you know that the Big Bang isn't actually the beginning of our Universe, but simply the current limit of our knowledge?

In this new episode, Christophe Pauly welcomes theoretical physicist and cosmologist Jean-Philippe Uzan for a breathtaking journey to the frontiers of physics. From the mysteries of the origins of the cosmos to fascinating theories about infinity, discover how scientists are trying to decipher our reality without falling into the trap of science fiction.

Is there an exact copy of yourself in a parallel universe? How did Albert Einstein's theory of relativity revolutionize our understanding of time and gravity? What traces could primordial gravitational waves reveal about what existed "before" the Big Bang? Delve into the grand history of cosmology and understand why abandoning scientific experimentation in favor of pure theory could endanger science.
