Expanding Our Horizons: Rethinking Gravity's Role in the Quantum-to-Classical Transition
The episode discusses the paper "Expanding Our Horizons," which challenges traditional models of how gravity causes the universe to transition from quantum origins to a classical state. The hosts introduce the Wigner function as a tool that suggests non-linear evolution might actively generate persistent quantum coherence on super-horizon scales, questioning if gravity always leads to complete classicalization.
