Theory of Everything Controversies: Livestream
Summary
This episode features a panel discussion with astrophysicist Brian Keating, Eric Weinstein, Sabina Hossenfelder, and Lee Smolin regarding the stalled progress in finding a theory of everything. The guests debate the failures of string theory and grand unification, arguing that the community has lost focus on testable predictions and the fundamental inconsistencies between quantum mechanics and gravity.
