Episode Details

Prof. Jim Al-Khalili is a theoretical physicist, author, and public broadcaster who holds a chair in physics at the University of Surrey. Known for his BBC documentaries and popular science books, including On Time and The World According to Physics, his work spans quantum mechanics, nuclear reaction theory, and the fundamental nature of space-time.  

Jim and I discuss the divide between psychological "manifest time" and the laws of physics. Jim explains general relativity, gravitational time dilation, and the astrophysics behind Interstellar, before tackling the mathematical conflict between general relativity and quantum mechanics. Jim breaks down quantum entanglement, Bell’s Inequality, and competing models of reality-from the Copenhagen view to the Many-Worlds interpretation. Finally, we discuss how AI systems are formalizing complex mathematical theorems and processing deep-space data to decode dark matter and dark energy.
