Professor Brian Greene reveals the biggest questions science still can’t answer, whether we’re living in a simulation, why AI may deserve human rights, and what happens at the end of the universe!

Professor Brian Greene is a theoretical physicist, mathematician, and Professor of Physics and Mathematics at Columbia University, where he also directs the Center for Theoretical Physics. He is a leading researcher in string theory, the co-founder of the World Science Festival, and the bestselling author of several books, including ‘Until the End of Time: Mind, Matter, and Our Search for Meaning in an Evolving Universe’.

He explains: ◼ Why most physicists believe time travel into the future is already possible ◼ Why he believes humans don't actually have free will ◼ How string theory could reveal what everything in the universe is really made of ◼ Why the "Pale Blue Dot" changes how you see your own life and problems ◼ Why the search for meaning may matter more than finding the answer itself
