According to Cox, black holes are intriguing because they challenge the compatibility of quantum theory and general relativity, creating a fundamental clash in our understanding of nature. Unifying these two pillars of physics is a major goal for theoretical physicists, and black holes are crucial in this pursuit. He also delves into the characteristics of black holes, describing the event horizon as a boundary between the external universe and the interior of the black hole. In conclusion, he says, black holes play a pivotal role in our understanding of the universe, pushing scientists to explore the nature of space, time, and the fundamental laws of physics. They offer a glimpse into something deeply hidden, potentially leading to a profound shift in our comprehension of reality.

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.
