Each week, Jim al-Khalili invites a leading scientist to tell us about their life and work. He’ll talk to Nobel laureates as well as the next generation of beautiful minds to find out what inspires and motivates them and what their discoveries might do for us.
Jim enters the multiverse with Astronomer Royal Martin Rees. He’s worked on the big bang, black holes and the formation of galaxies but wants to know if there’s life elsewhere.
