Ep 121AaS! 121: Is String Theory Worth It? (Part 7: A Correspondence from a Dear Friend)

How did String Theory get started? What has made the idea so popular over the decades? Can we ever truly have a theory of quantum gravity? What is supersymmetry, the landscape, and the AdS/CFT Correspondence? What do holograms have to do with this? How many dimensions do we live in? Why does String Theory have such a hard time making predictions? How are we supposed to judge a theory that isn't done yet? It's a non-stop String Theory bonanza as I discuss these questions and more in today's Ask a Spaceman!
