Jonathan Oppenheim: A Universe Where Gravity Resists Quantization

Jonathan Oppenheim: A Universe Where Gravity Resists Quantization

Jonathan Oppenheim (UCL) proposes stochastic coupling between quantum mechanics and gravity as post-quantum theory. He discusses the nature of classical mechanics, discrete versus continuous space, and the prospects of post‑quantum theories of gravity.- 00:00:00 - Introduction- 00:02:37 - Integrating general relativity and quantum theory- 00:05:18 - The nature of classical mechanics- 00:10:12 - Discrete vs continuous space in physics- 00:13:32 - Boundary of physics and philosophy- 00:18:44 - Post-quantum theory of classical gravity- 00:20:00 - Mongrel relativity- 00:24:00 - Issue of causal structure in quantum theory of gravity- 00:27:18 - Gravity and string theory- 00:34:26 - Quantum-classical system coupling (Feynman's position)- 00:45:31 - Quantum vs post-quantum noise- 00:58:08 - Quantum thermodynamics and the multiple Second Laws- 01:03:35 - No-go theorem and classical gravity- 01:06:09 - Bohmian mechanics vs many-worlds- 01:08:07 - Advice for quantum gravity researchers- 01:13:57 - Independent study and learning- 01:15:35 - Graviton entanglement testing- 01:20:05 - The struggle of podcasting (Theories of Everything's journey)- 01:21:26 - Future projects for TOE- 01:24:52 - Gratitude for supportSPONSORS:- Patreon: early access to ad‑free audio episodes! https://patreon.com/curtjaimungal- Crypto https://tinyurl.com/cryptoTOE- PayPal https://tinyurl.com/paypalTOE- 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- Pandora https://pdora.co/33b9lfP- Spotify https://open.spotify.com/show/4gL14b92xAErofYQA7bU4e- Subreddit r/TheoriesOfEverything https://reddit.com/r/theoriesofeverything- TOE Merch https://tinyurl.com/TOEmerchRESOURCES:- Podcast w/ Nicholas Gisin on TOE: https://youtu.be/jcHzgy0I6gk- Jonathan Oppenheim's Quanta video: https://www.youtube.com/watch?v=DkRbNXILroI- Chapel Hill Conference Documentary on Quantum Gravity (Curt Jaimungal): https://youtu.be/eBA3RUxkZdc- The Second Laws of Quantum Thermodynamics: https://arxiv.org/abs/1305.5278- Podcast w/ Chiara Marletto on TOE: COMING SOON https://youtube.com/TheoriesOfEverything- Podcast with Lue Elizondo on TOE: https://youtu.be/wULw64ZL1Bg- Podcast with Edward Frankel on TOE: https://youtu.be/n_oPMcvHbAc- Podcast w/ Theo Von on TOE: https://youtu.be/1cziCepYeEM?t=4673- Podcast w/ Joscha Bach on TOE: https://youtu.be/3MNBxfrmfmI- Podcast w/ Noam Chomsky on TOE: https://www.youtube.com/playlist?list=PLZ7ikzmc6zlORiRfcaQe8ZdxKxF-e2BCY- Podcast w/ Stephen Wolfram on TOE: https://youtu.be/1sXrRc3Bhrs- Every TOE Playlist: https://www.youtube.com/@TheoriesofEverything/playlists 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.
