Ruth Kastner: Can the Future Influence the Past? Retrocausality in Quantum Theory  
Podcast: Theories of Everything with Curt Jaimungal
Published On: Fri Feb 07 2025
Description: Ruth Kastner and Curt Jaimungal explore the transactional interpretation of quantum mechanics, tackling the measurement problem, retrocausality, and the quest to reconcile quantum theory with gravity. Kastner argues for a paradigm shift that embraces complexity and nuance in understanding quantum phenomena.- 00:00 - Introduction- 01:40 - Measurement Problem- 09:17 - Measurement Interaction- 11:27 - Feynman Diagrams- 16:25 - Observers vs Measurers- 20:58 - Nature of Measurement- 22:19 - Probabilistic Outcomes- 28:52 - Emission and Absorption- 34:40 - Entities and Reality- 38:03 - Emergence of Space-Time- 41:14 - Theories and Anomalies- 42:56 - Independent Scholarship- 46:23 - Conventional Approach- 48:33 - Transactional Axioms- 50:34 - Kramer's Perspective- 1:07:22 - Retrocausality and Block World- 1:07:43 - Science Fiction and Time Travel- 1:14:04 - Emergence of Space-Time Events- 1:27:23 - Weak and Strong Forces- 1:36:10 - Physics to Philosophy- 1:39:53 - Free Will- 1:45:36 - Consciousness and Physicalism- 1:54:51 - Challenges to Materialism- 2:05:47 - Advice for Future Generations- 2:07:41 - Conclusion and AcknowledgmentsSPONSORS:- The Economist: 20% off discount - https://www.economist.com/toe- Curt Jaimungal Substack: https://curtjaimungal.substack.com- Spotify video: https://tinyurl.com/SpotifyTOE- YouTube Membership: https://www.youtube.com/channel/UCdWIQh9DGG6uhJk8eyIFl1w/join- Patreon: https://patreon.com/curtjaimungal- Twitter: https://twitter.com/TOEwithCurt- Discord: https://discord.com/invite/kBcnfNVwqs Learn more about your ad choices.
