Urs Schreiber: The Emergence of the Super Point from Nothing
Published 1 year ago
Description
In this episode Urs Schreiber explains how higher category theory can generate physical structures—from the empty set to fermions and even 11‑dimensional supergravity—by treating mathematics as the structure of structure. The discussion weaves philosophy, topology, and gauge theory to show how “something” can emerge from “nothing.”
