Julian Barbour: When Physics Gets Rid of Time and Quantum Theory

In this episode physicist Julian Barbour argues that time is an illusion and that quantum mechanics may be replaced by a theory based on relational ratios. He explores how entropy, consciousness, and the structure of the universe can be understood without fundamental time or wave functions.- 00:00 - Introduction- 01:35 - Consciousness and the Nature of Reality- 3:23 - The Nature of Time and Change- 7:01 - The Role of Variety in Existence- 9:23 - Understanding Entropy and Temperature- 36:10 - Revisiting the Second Law of Thermodynamics- 41:33 - The Illusion of Entropy in the Universe- 46:11 - Rethinking the Past Hypothesis- 55:03 - Complexity, Order, and Newton's Influence- 1:02:33 - Evidence Beyond Quantum Mechanics- 1:16:04 - Age and Structure of the Universe- 1:18:53 - Open Universe and Ratios- 1:20:15 - Fundamental Particles and Ratios- 1:24:20 - Emergence of Structure in Age- 1:27:11 - Shapes and Their Explanations- 1:32:54 - Life and Variety in the Universe- 1:44:27 - Consciousness and Perception of Structure- 1:57:22 - Geometry, Experience, and Forces- 2:09:27 - The Role of Consciousness in Shape DynamicsSPONSORS:- The Economist: 20% off discount. https://www.economist.com/toe- Substack: https://curtjaimungal.substack.com- Spotify: https://tinyurl.com/SpotifyTOE- YouTube Membership: https://www.youtube.com/channel/UCdWIQh9DGG6uhJk8eyIFl1w/joinRESOURCES:- Julian's previous appearance on TOE: https://www.youtube.com/watch?v=bprxrGaf0Os- Neil Turok on TOE (Big Bang): https://www.youtube.com/watch?v=ZUp9x44N3uE- Neil Turok on TOE (Black Holes): https://www.youtube.com/watch?v=zNZCa1pVE20- Debunking "All Possible Paths": https://www.youtube.com/watch?v=XcY3ZtgYis0- John Vervaeke on TOE: https://www.youtube.com/watch?v=GVj1KYGyesI- Jacob Barandes & Scott Aaronson on TOE: https://www.youtube.com/watch?v=5rbC3XZr9-c- The Dark History of Anti-Gravity: https://www.youtube.com/watch?v=eBA3RUxkZdc- Peter Woit on TOE: https://www.youtube.com/watch?v=TTSeqsCgxj8- The Monadology - G.W.
