Jacob Barandes: There Is No Quantum Multiverse (Here's the Proof)
2 tim 55 min•18 februari 2025
Curt Jaimungal talks with Harvard physicist Jacob Barandes about the foundations of quantum mechanics, wave‑particle duality, and Jacob’s proposal of an indivisible stochastic formulation. The conversation also revisits historic debates from Schrödinger to Einstein and explores new directions for quantum theory.
