Witten shares the remarkable history of how a failed model for nuclear physics became a leading candidate for a Theory of Everything. He discusses the Superstring Revolutions, the role of extra dimensions, supersymmetry, and dualities, and how recent advances like holography and quantum gravity are reshaping the field. At the same time, he candidly addresses the challenges the theory faces today — from the vast “landscape” of possible universes to the lack of direct experimental confirmation.

Whether you’re a physics student, a curious thinker, or someone who just loves great science storytelling, this episode offers a rare opportunity to hear from one of the field’s deepest thinkers as he reflects on where we’ve been — and where we might be going.
