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.0:00 Introduction2:37 Integrating general relativity and quantum theory5:18 The nature of classical mechanics10:12 Discrete vs continuous space in physics13:32 Boundary of physics and philosophy18:44 Post-quantum theory of classical gravity20:00 Mongrel relativity24:00 Issue of causal structure in quantum theory of gravity27:18 Gravity and string theory34:26 Quantum-classical system coupling (Feynman's position)45:31 Quantum vs post-quantum noise58:08 Quantum thermodynamics and the multiple Second Laws1:03:35 No-go theorem and classical gravity1:06:09 Bohmian mechanics vs many-worlds1:08:07 Advice for quantum gravity researchers1:13:57 Independent study and learning1:15:35 Graviton entanglement testing1:20:05 The struggle of podcasting (Theories of Everything's journey)1:21:26 Future projects for TOE1:24:52 Gratitude for supportSPONSORS:- Patreon: early access to ad‑free audio episodes! https://patreon.com/curtjaimungal- Crypto Crypto: https://nowpayments.io/donation/TOE- 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.
