I made a video asking Tim Palmer about why he uses a p-adic metric to model state space in physics, invariant set theory and the fractal nature of Peter Scholze's perfectoid spaces

We go over: 1. State space uses a p-adic metric as opposed to a Euclidean metric 2. Hilbert space is discrete rather than continuous 3. Counterfactual universes are not only hypothetical but inaccessible 4. Qubit information density may depend on the size of the universe 5. Gravity as the source of decoherence in quantum mechanics 6. Fractal cosmology 7. Peter Scholze's perfectoid spaces 8. Rational quantum mechanics 9. The ongoing debate in Bell's Theorem and free will 10. Invariant Set Theory 11. Wormholes as the reason for entanglement (ER = EPR) 12. The Virgo Supercluster lottery 13. Discretizing the Riemann sphere and Niven's Theorem (the Impossible Triangle Corollary) Tim Palmer, CBE, FRS, (Commander of the Order of the British Empire, Fellow of the Royal Society) is a professor at the University of Oxford. He received his PhD in General Relativity under Dennis Sciama, who also supervised Stephen Hawking, David Deutsch and Martin Rees. After receiving his PhD, Professor Palmer turned down a postdoctoral research position with Stephen Hawking to join the UK’s Met Office and subsequently spent much of his career in climate physics, becoming an expert in chaos theory and fractals. He is well known for proposing the ideas of Invariant Set Theory and Rational Quantum Mechanics. His research interests include modeling state space with the p-adic metric, Bell’s Theorem and foundations of quantum mechanics, superdeterminism, counterfactual universes, quantum computing and finding a gravitational theory of the quantum, as opposed to a quantum theory of gravity.
