Sal Pais and Stephon Alexander: The Physics of Negative Energy

Sal Pais and Stephon Alexander explore singularities, negative energy, and the origins of the universe, debating quantum gravity and the superforce. They also discuss the Ashtekar quantum bounce, holographic ideas, and the rhythmic universe concept.- 00:00:00 - Introduction- 00:03:03 - Main issues of quantum gravity- 00:08:08 - Academia vs. the Outside- 00:11:54 - Superforce- 00:25:09 - Ashtekar quantum bounce- 00:32:11 - Mathematics of singularity repulsion- 00:40:10 - Fermionic matter and loop quantum gravity- 00:44:08 - Negative energy- 00:51:11 - What is the cause of gravity?- 00:52:50 - Casimir forces and gravity- 00:56:38 - Ed Witten on String Theory- 01:02:53 - AdS / CFT (defending holography)- 01:10:15 - The "rhythm" universe (a universe that continually comes and goes)- 01:15:46 - The Pais Effect and patents- 01:31:59 - Sal Pais (Part 2) and Stephon Alexander (Part 2)- 01:33:46 - SaxophoneSPONSORS:- Brilliant: 20% off https://brilliant.org/TOEEvery episode days early, ad-free, plus my essays: https://curtjaimungal.substack.com/subscribeRESOURCES:- YouTube link: https://youtu.be/PE4C7OI7Frg- New TOE Website (early access to episodes): https://theoriesofeverything.org/- Patreon: https://patreon.com/curtjaimungal- 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- Physics / Consciousness Contest: https://youtu.be/V93GQaDtv8w- Curt's Crash Course on Physics: https://youtu.be/e8kyvdPP8os- Sal Pais podcast: https://youtu.be/5E6QyAhTB3o- Stephon Alexander podcast: https://youtu.be/VETxb96a3qk- Stephon's Book "Fear Of Black Universe": https://amzn.to/3EYRpsJ- Stephon's Book "The Jazz Of Physics": https://amzn.to/3CIPiGI 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.
