Roger Penrose: Why Quantum Mechanics Needs a New Foundation

Sir Roger Penrose explains twistor theory, singularity theorems, and their implications for quantum cosmology. We discuss his singularity theorems, the chiral nature of twistors, extra dimensions, and the philosophical implications for free will and the nature of reality.- 00:00 - Intro- 01:22 - Twistors & cosmology- 15:00 - Most significant thought- 20:45 - Twistors are chiral- 25:34 - Extra dimensions- 27:02 - Geometry overview- 37:57 - Grothendieck- 40:36 - Gravity & QM- 43:00 - Wave function collapse- 53:04 - Gravitational fields & wave function- 01:11:02 - Free will- 01:14:03 - Discrete vs continuous universe- 01:16:35 - AI capabilities- 01:19:09 - Many worlds theory- 01:20:38 - Idealism- 01:21:35 - CCC- 01:23:31 - Penrose’s legacy- 01:33:25 - Outro & supportSPONSORS:- I personally subscribe to The Economist.
