Will We Ever Prove String Theory?
String Theory, Astronomy and podcast with Cumrun Vafa
The Joy of Why, Hosted by Janna Levin and Steven Strogatz
About
Cumrun Vafa discusses the gap between string theory's mathematical possibilities and experimental tests. The conversation considers the landscape of candidate universes, the swampland programme for ruling out inconsistent possibilities, dimensional constraints and the role of cosmological observations in seeking predictions relevant to our Universe.
