In this episode, theoretical physicist Claudia de Rham returns to discuss the possibility that gravity has mass, challenging core assumptions of general relativity and offering new perspectives on dark energy. The conversation also explores implications for cosmology, quantum gravity, and the foundations of physics.- 00:00 - Introduction- 01:20 - Claudia's Approach- 09:11 - Claudia's Motivation- 14:45 - Dark Energy- 23:35 - Causality- 27:19 - Other Approaches- 45:10 - New Physics- 50:47 - Dark Energy (cont)- 57:36 - Quantum Gravity / String Theory- 01:14:10 - Gravitons & Photons- 01:21:44 - Symmetry- 01:30:25 - Double Slit Experiment- 01:50:15 - Cosmology- 01:54:45 - Massive Graviton- 02:00:10 - ConclusionSPONSORS:- ver.so: Use code TOE for 15% off - https://ver.so- The Economist: 20% off for TOE listeners - https://www.economist.com/toe- Patreon: Support TOE - https://patreon.com/curtjaimungal- Substack: Curt Jaimungal personal writings - https://curtjaimungal.substack.com- Spotify: Listen on Spotify - https://tinyurl.com/SpotifyTOE- YouTube Membership: Early access videos - https://www.youtube.com/channel/UCdWIQh9DGG6uhJk8eyIFl1w/join- Twitter: https://twitter.com/TOEwithCurt- Discord: https://discord.com/invite/kBcnfNVwqsRESOURCES:- The Beauty of Falling (Claudia's book): https://amzn.to/4i4Z9cx- Claudia's published papers: https://profiles.imperial.ac.uk/c.de-rham/publications- Claudia's first appearance on TOE: https://www.youtube.com/watch?v=Ve_Mpd6dGv8&t=83s&ab_channel=CurtJaimungal- Carlo Rovelli on TOE: https://www.youtube.com/watch?v=hF4SAketEHY- Curt's Substack article on energy: https://curtjaimungal.substack.com/p/what-is-energy-actually- Neil Turok on TOE: https://www.youtube.com/watch?v=ZUp9x44N3uE- Tim Palmer on TOE: https://www.youtube.com/watch?v=vlklA6jsS8A- DESI article on The Economist: https://www.economist.com/science-and-technology/2024/06/19/the-dominant-model-of-the-universe-is-creaking- String Theory Iceberg on TOE: https://www.youtube.com/watch?v=X4PdPnQuwjY- Leonard Susskind on TOE: https://www.youtube.com/watch?v=2p_Hlm6aCok- Chiara Marletto and Vlatko Vedral on TOE: https://www.youtube.com/watch?v=Uey_mUy1vN0- TOE's telling of "The Dark History of Anti-Gravity": https://www.youtube.com/watch?v=eBA3RUxkZdc- Positive Signs in Massive Gravity (paper): https://arxiv.org/pdf/1601.04068 Learn more about your ad choices.
