The Emergence of the Super Point from Nothing

Theories of Everything with Curt Jaimungal

I'm back, baby. I've been away traveling for podcasts and am excited to bring you new ones with Michael Levin, William Hahn, Robin Hanson, and Emily Riehl, coming up shortly. They're already recorded. I've been recovering from a terrible flu but pushed through it to bring you today's episode with Urs Schreiber. This one is quite mind-blowing. It's quite hairy mathematics, something called higher category theory, and how using this math (which examines the structure of structure) allows one manner of finding "something" from "nothing." Here, "nothing" means the empty set, and "something" is defined as fermions and even 11D supergravity. It's the first time this material has been presented in this manner. Enjoy.
