Felix Finster: How Dirac's 90-Year-Old Error Unifies All of Physics

Felix Finster proposes causal fermion systems unify physics by building spacetime from quantum correlations. The conversation covers the Dirac sea, emergence of geometry, the Born rule, and implications for quantum gravity and cosmology.
