Julian Barbour: What Happens When Physics Abandons Time Entirely

from Theories of Everything with Curt Jaimungal · host Theories of Everything

Julian Barbour argues that time is an illusion and quantum mechanics should be replaced by 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.
