Sir Roger Penrose

Date: 2018-12-18 | Duration: 1h 40m

Episode Overview

Sir Roger Penrose delves into the profound mysteries of consciousness, quantum mechanics, and cosmology during his conversation with Joe Rogan. He challenges the notion that consciousness is merely computational, suggesting instead that it involves deeper, non-algorithmic processes possibly linked to quantum phenomena in the brain’s microtubules. Penrose reflects on the limitations of formal logic and algorithms, drawing on Gödel’s incompleteness theorems to argue that human understanding transcends mechanical computation. He also discusses the role of quantum mechanics, including the measurement problem and wave function collapse, emphasizing that standard interpretations remain incomplete and unsatisfactory. The discussion then shifts to Penrose’s groundbreaking work on black holes and the nature of singularities. He recounts the development of mathematical theorems proving the inevitability of singularities in gravitational collapse and explores the implications for the universe’s structure and fate. Penrose also touches on dark matter, dark energy, and the cosmological constant, highlighting ongoing puzzles in modern physics. Throughout, he shares insights on the search for extraterrestrial intelligence and the challenges of testing speculative ideas, advocating for theories grounded in rigorous mathematics and empirical evidence. The episode offers a rich exploration of the frontiers of physics and consciousness from one of the field’s most original thinkers.

About Sir Roger Penrose

Sir Roger Penrose OM FRS is a distinguished English mathematical physicist, mathematician, and philosopher of science, renowned for his groundbreaking contributions to the understanding of black holes and the nature of consciousness. As the Emeritus Rouse Ball Professor of Mathematics at the University of Oxford and an Emeritus Fellow of Wadham College, Penrose has received numerous accolades, including the prestigious 2020 Nobel Prize in Physics for his work on gravitational singularities. His intriguing theories, such as the Penrose tiling and his exploration of the interplay between physics and consciousness, have made him a captivating figure in both scientific and philosophical discussions. Through his appearances, including on the Joe Rogan Experience, Penrose invites audiences to ponder the mysteries of the universe and the complexities of the mind.

Transcript Excerpt

Starting point is 00:00:00 All right, here we go. Three. Boom. And we're live. How are you, sir? Starting point is 00:00:33 And your belief that consciousness is not simply calculation, but that there's something more to it. Starting point is 00:01:16 I'll spend some of the time going to other talks that might be interesting. Starting point is 00:01:56 particle and it could be in one spot or it could be in another spot then you have all sorts of Starting point is 00:02:32 and I had some vague memory of something about energy, Starting point is 00:03:01 man called Steen who talked on mathematical logic and he Starting point is 00:03:34 logic Starting point is 00:03:51 And I didn't like that idea. Starting point is 00:04:12 there's the Goldbach conjecture which Starting point is 00:04:34 But the idea, often, is in mathematics, Starting point is 00:05:07 And you say, maybe I've got a proof. Starting point is 00:05:20 That just goes on forever. Starting point is 00:05:49 then if it says yes, that's something you believe. Starting point is 00:06:17 But you can also see by the way it's constructed that it cannot be proved by this procedure. Starting point is 00:07:07 Is it something following rules? Is this an algorithm? Well, this more or less says it's Starting point is 00:07:58 playing music or falling in love or whatever these things might be, Starting point is 00:08:30 Well, what about Newton's mechanics? Starting point is 00:08:52 You can put that on a computer. Starting point is 00:09:21 Well, because of calculations. Starting point is 00:09:45 There's many more parameters you've got to worry about. But it's just as computable as these other things. Starting point is 00:10:30 in which the cat would be dead and alive at the same time, Starting point is 00:10:56 Now, everybody knows that who does quantum mechanics, Starting point is 00:11:26 involved in our understandings of things. Starting point is 00:11:44 okay, you have two computers talking to each other over th...
