Stephon Alexander: The Autodidactic Universe Learns Its Own Laws
1 tim 34 min•19 januari 2022
Stephon Alexander joins Curt to explore the Autodidactic Universe, matrix models versus string theory, and Chern‑Simons gravity, while debating evolutionary cosmology, anomalies, and practical advice for self‑studying advanced physics.
0:00 Introduction
4:46 BTS banter and framing the conversation
6:05 The Autodidactic Universe
18:54 BMN vs BFSS (type IIA String Theory)
26:45 Lee Smolin's evolutionary model of the universe as black hole spawn
29:06 Matrix models linked to particles rather than laws
30:36 Explaining D‑branes and their dimensionality
36:02 When watching TOE, it's okay to be confused
36:55 Chern‑Simons Gravity
49:03 Anomaly Cancellations
51:43 Klein Gordon equation and renormalization
55:55 What is a Theory of Everything? Conditions?
59:15 Story about Curt's brother's "genius"
1:02:40 Doubting your own mathematical abilities
1:06:02 Advice for learners in 20s‑40s studying String Theory
1:10:24 Brian Keating is no friend to Stephon (kidding)
1:11:08 How does learning math / physics change with age?
1:15:14 Anomalies and purposeful mistakes leading to insights
1:18:02 No Go theorems (and AdS / CFT correspondence)
1:23:26 Why does the Graviton have Spin 2?
1:25:41 Gems in Geometric Unity
1:29:12 Opinion on Stephen Wolfram's theory / project
1:31:05 Future plans for TOE: Geometric Algebra and Categorical Unification
