Felix Finster: Dirac's 90-Year-Old "Mistake" Unifies All of Physics

In this episode Curt Jaimungal talks with Professor Felix Finster about his causal fermion systems framework, a radical approach that builds spacetime and quantum physics from underlying correlations. The conversation covers the Dirac sea, emergence of geometry, the Born rule, and implications for quantum gravity and cosmology.- 00:00 - Introduction- 03:12 - The Origins of Causal Fermion Systems- 06:55 - Engaging with Alternative Theories in Physics- 15:22 - The Standard View of Causation- 18:21 - Classical, Quantum, and Pre-Quantum- 23:06 - How Spacetime Emerges from Disconnected Points- 29:49 - Recovering Lorentz Signature Without Assumptions - 31:48 - Recovering the Born Rule from First Principles - 39:39 - The Measurement Problem- 46:20 - Bounds on CSL Parameters- 49:45 - The Dynamics of Spacetime - 57:47 - Collaboration with Yao and Reflections on the Theory - 1:03:13 - A Quantum Gravity Theory Without Supersymmetry - 1:05:28 - The Dirac Sea- 1:11:40 - Addressing Infinite Energy in Semi-Classical Gravity- 1:13:09 - Octonions in the Vacuum Structure- 1:17:32 - Chirality and the Action Principle - 1:20:33 - Baryogenesis and Why Matter Exists- 1:35:10 - Rethinking the Strong CP and Hierarchy Problems- 1:38:43 - Recognition, Collaboration, and Growing Attention- 1:54:00 - Mathematical Criteria vs. Experimental Tests- 2:01:02 - Advice for Young ResearchersRESOURCES:- Felix's Papers: https://scholar.google.com/citations?user=F7ppNroAAAAJ- Felix's Bio: https://www.uni-regensburg.de/mathematik/mathematik-1/startseite/index.html- Causal Fermion Systems [Paper]: https://arxiv.org/pdf/2405.19254- Linear Dynamics of Wave Functions [Paper]: https://arxiv.org/pdf/2101.08673- The Principle of the Fermionic Projector [Book]: https://www.amazon.com/Principle-Fermionic-Projector-Advanced-Mathematics/dp/0821839748- Baryogensis for Causal Fermion Systems [Paper]: https://arxiv.org/pdf/2111.05556- Holographic Mixing [Paper]: https://arxiv.org/pdf/2410.18045- Standard Model Physics from an Algebra?
