Leonard Susskind: The Crisis in String Theory Runs Even Deeper

Leonard Susskind: The Crisis in String Theory Runs Even Deeper

Leonard Susskind joins us to discuss why the crisis in string theory is deeper than most realize, examining its conceptual limits and the search for a more complete quantum gravity framework. We explore the history of the theory, recent critiques, and possible paths forward.- 00:00 - IntroSPONSORS:- The Economist: 20% off discount. https://www.economist.com/toeRESOURCES:- New Substack!
