Visit https://www.economist.com/toeToday we are joined by theoretical physicist Claudia de Rham for her return appearance on Theories of Everything with Curt Jaimungal to discuss the possibility that gravity itself has mass. In this mind-bending conversation, she explores how this idea challenges long-held assumptions in general relativity and opens the door to a new understanding of dark energy and the structure of the universe. We also dive into the frontiers of cosmology, quantum gravity, and what it means to question the foundations of physics.Join My New Substack (Personal Writings): https://curtjaimungal.substack.comListen on Spotify: https://tinyurl.com/SpotifyTOEBecome a YouTube Member (Early Access Videos):https://www.youtube.com/channel/UCdWIQh9DGG6uhJk8eyIFl1w/joinLinks Mentioned:• 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/1601.04068Timestamps:00:00 - Introduction01:20 - Claudia's Approach09:11 - Claudia's Motivation14:45 - Dark Energy23:35 - Causality27:19 - Other Approaches45:10 - New Physics50:47 - Dark Energy (continued)57:36 - Quantum Gravity / String Theory01:14:10 - Gravitons & Photons01:21:44 - Symmetry01:30:25 - Double Slit Experiment01:50:15 - Cosmology01:54:45 - Massive Graviton02:00:10 - ConclusionSupport TOE on Patreon: https://patreon.com/curtjaimungal Twitter: https://twitter.com/TOEwithCurtDiscord Invite: https://discord.com/invite/kBcnfNVwqs#science Learn more about your ad choices.
