Large Unified Quantum Horizon Thermodynamics:

From Loop Quantum Cosmology Bounce to Dark Energy and Black Hole Information Flow

Abstract

This paper addresses three fundamental problems in modern cosmology: the origin of the universe, the nature of dark energy, and the behavior of black holes. We show that the cosmic horizon — the boundary of the observable universe — radiates thermal energy following the same laws as black holes, and that this radiation naturally drives cosmic acceleration. A dynamic UV/IR running cutoff resolves the 368-order-of-magnitude scale crisis without any fine-tuning, requiring only a coupling constant of order unity. The same thermodynamic framework yields an explicit formula for the rate at which information flows across a rotating, charged black hole horizon. Numerical integration across 70 e-folds of cosmic expansion satisfies the governing equations to better than one part in 10^14 and fits 32 independent Hubble-parameter measurements with a reduced chi-squared of 0.85.
