“Could black holes be the key to a quantum theory of gravity, a deeper theory of how reality, of how space and time works?”

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?

About Brian Cox:
Brian Cox obtained a first class honors degree in physics from the University of Manchester in 1995 and in 1998 a Ph.D. in High Energy Particle Physics at the DESY laboratory in Hamburg. 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.
