Julian Barbour: The Physicist Who Says Time Does Not Exist

Curt Jaimungal sits down with Julian Barbour to examine the claim that time is not fundamental but emerges from change. They discuss shape dynamics, the universe’s increasing order, and how Barbour’s ideas challenge traditional entropy and cosmology.- 00:00 - Introduction- 02:12 - Working Outside of Academia- 03:53 - Space, Time, Dimension- 10:40 - Mach's Principle- 21:33 - Mach Confused Einstein- 24:22 - Two Particle Universe- 31:46 - Carlo Rovelli- 35:02 - Julian's Ontology- 43:37 - Julian's Theory 'Shape Statistics'- 51:11 - Leibniz's Philosophical Writings- 56:14 - Expansion of the Universe (Scale Invariance)- 01:05:02 - Cosmological Principle- 01:15:34 - Thermodynamics- 01:17:15 - Entropy and Complexity- 01:30:40 - Wave Function / Double Slit Experiment- 01:39:21 - God- 01:44:48 - The Role of Instruments- 01:47:44 - Etymology of Pattern and Matter- 01:51:25 - Join My Substack!SPONSORS:- The Economist: 20% off discount. https://www.economist.com/toeRESOURCES:- Support TOE on Patreon: https://patreon.com/curtjaimungal (early access to ad-free audio episodes!)- Enjoy TOE on Spotify! https://tinyurl.com/SpotifyTOE- Become a YouTube Member Here: https://www.youtube.com/channel/UCdWIQh9DGG6uhJk8eyIFl1w/join- Join TOE's Newsletter 'TOEmail' at https://www.curtjaimungal.org- The Janus Point (Julian Barbour's book): https://www.amazon.com/Janus-Point-New-Theory-Time/dp/0465095461- 'Relational Concepts of Space and Time' (Julian Barbour's 1982 paper): https://www.jstor.org/stable/687224- 'The Theory of Gravitation' (Paul Dirac's 1958 paper): https://www.jstor.org/stable/100497- Carlo Rovelli on TOE: https://www.youtube.com/watch?v=hF4SAketEHY- 'On the Nature of Things' (book): https://www.hup.harvard.edu/books/9780674992009- Leibniz: Philosophical Writings (book): https://www.amazon.com/Leibniz-Philosophical-Writings-Everymans-University/dp/0460119052- Elementary Principles of Statistical Mechanics (book): https://www.amazon.com/Elementary-Principles-Statistical-Mechanics-Physics/dp/0486789950- The interpretations of quantum mechanics in 5 minutes (article): https://curtjaimungal.substack.com/p/the-interpretations-of-quantum-mechanics- Sean Carroll on TOE: https://www.youtube.com/watch?v=9AoRxtYZrZo- Twitter: https://twitter.com/TOEwithCurt- Discord Invite: https://discord.com/invite/kBcnfNVwqs- iTunes: https://podcasts.apple.com/ca/podcast/better-left-unsaid-with-curt-jaimungal/id1521758802- Subreddit r/TheoriesOfEverything: https://reddit.com/r/theoriesofeverything Theories of Everything with Curt Jaimungal features long-form, technically detailed interviews with leading researchers in physics, mathematics, consciousness, and philosophy, exploring topics at the level of active research.
