Hubble Tension as an Effect of Horizon Entanglement Nonequilibrium
The episode discusses the paper "Hubble Tension as an Effect of Horizon Entanglement Nonequilibrium," which addresses discrepancies in Hubble constant measurements. It proposes that non-equilibrium physics at the cosmic horizon generates a measurable energy component (HEED). This effect is negligible early on but provides a late-time boost to H 0, offering a physically motivated solution consistent with existing observational data.
