Today we explore a problem that has haunted theoretical physicists for decades and remains a topic of active debate do black holes destroy information? A key precept in quantum theory is that information should be conserved, yet anything that falls into a black hole is seemingly obliterated. How can we reconcile our theories of gravity with that of the quantum world? And could the answer transform the way we look at the Universe...

Written & presented by Prof. David Kipping. Special thanks to Prof Janna Levin for fact checking and for her wonderful book that inspired this video, "Black Hole Survival Guide" https://a.co/d/eqqP6z1
