Brian Cox: Why black holes could hold the secret to time and space | Full Interview

“Could black holes be the key to a quantum theory of gravity, a deeper theory of how reality, of how space and time works?” Subscribe to Big Think on YouTube ► https://www.youtube.com/channel/UCvQECJukTDE2i6aCoMnS-Vg?sub_confirmation=1 Up next, Brian Cox: The quantum roots of reality ► https://www.youtube.com/watch?v=kO41iURud9c&pp=0gcJCY0JAYcqIYzv Black holes are forcing us to rethink everything we know about the very foundations and limits of physics. These mysterious objects challenge our understanding of time, space, and information. In this full interview from 2023, Physicist Brian Cox explains why black holes aren’t just theoretical endpoints, but could lead us to a deeper understanding of reality altogether. What happens to information that falls into a black hole? Can space and time emerge from something more fundamental? And why did Einstein, Hawking, and generations of physicists struggle with the idea that these objects could even exist? 00:00:00 Black holes and the edge of physics 00:01:44 Hawking’s work 00:02:47 Historical roots 00:13:18 The “end of time” inside black holes 00:20:26 The black hole information paradox 00:24:31 Black holes and quantum computing 00:26:04 Supermassive black holes and galaxy formation 00:52:37 Alien life and the Fermi paradox 00:56:10 Rare Earth hypothesis 01:00:30 Von Neumann probes 01:02:13 The Dark Forest Hypothesis 01:06:32 The Great Filter 01:09:09 Earth’s near-destruction 01:10:11 The Great Silence 01:14:38 Preserving intelligence Read the video transcript ► https://bigthink.com/series/full-interview/brian-cox-black-holes/?utm_source=youtube&utm_medium=video&utm_campaign=youtube_description Check out our other videos from Brian Cox’s 2023 interview: Brian Cox on how black holes could unlock the mysteries of our universe ► https://www.youtube.com/watch?v=pGsbEd6w7PI Brian Cox on quantum computing and black hole physics ► https://www.youtube.com/watch?v=laGXRs9Ce70 Why haven’t we found aliens?

He is now Professor of Particle Physics at the University of Manchester, The Royal Society Professor for Public Engagement in Science and a Fellow of the Royal Society. Brian is widely recognized as the foremost communicator for all things scientific, having presented a number of highly acclaimed science programs for the BBC watched by billions internationally including ‘Adventures in Space and Time’ (2021), ‘Universe’ (2021), ‘The Planets’ (2018), ‘Forces of Nature’ (2016), ‘Human Universe’ (2014), ‘Wonders of Life’ (2012), ‘Wonders of the Universe’ (2011) and ‘Wonders of the Solar System’ (2010). As an author, Brian has also sold over a million books worldwide including ‘Black Holes’, ‘Universal: A Guide to the Cosmos’, ‘Quantum Universe’ and ‘Why Does E=mc2?’ with co-author Professor Jeffrey Forshaw. He has set several world records for his sell-out live tours, including his most recent tour Horizons which has taken in venues across the globe.
