Abstract

We show that stationary black holes and the evolving universe belong to fundamentally different thermodynamic regimes: black holes obey ordinary Bekenstein Hawking thermodynamics, whereas cosmology necessarily follows memory-bearing teleodynamics. We show that teleodynamics is not valid for black holes, but is unavoidable in an expanding cosmology. This provides a dynamical, semi-classical realization of the thermodynamic split conjecture and identifies memory accumulation as the natural source of deviations from the area law in cosmology. Our results suggest that quantum gravity should not seek to extrapolate black hole thermodynamics to the universe, but instead must incorporate horizon memory as a fundamental microscopic ingredient and consider cosmological constructions consistent with that.
