A Thermodynamic Framework for Cosmic Structure - The Law of Coherence Gravity and Spacetime Z Boudehri

Coherence Gravity: From Physical Principles to AI and Back — A Thermodynamic Law of Spacetime Restoration Description This work introduces Coherence Gravity, a new physical framework in which gravitation is reinterpreted as a thermodynamic coherence–restoration process rather than a purely geometric or force-based interaction. The theory is derived by translating a stability law from intelligent systems into a constitutive field equation for spacetime, once its abstract variables are formally identified with: the metric field gμνg_gμν, the stress-energy content TμνT_Tμν, and a structural deviation from a reference ground geometry gμν0g⁰_gμν0. In this framework, spacetime is not a passive arena but a regulated dynamical system that actively resists decoherence. Gravity emerges as the flow of metric restoration, driven by vacuum rigidity and limited by a saturation mechanism that preserves causality and stability. The resulting nonlinear field equation defines: an emergent operational time (“Coherence Time”) proportional to the rate of structural repair, a vacuum rigidity term that replaces dark matter phenomenology in galactic dynamics, a saturation-limited backloop that stabilizes early-universe evolution and resolves the cosmic age tension, and a multi-stable coherence landscape that allows phase-separated metric domains without invoking parallel universes. The framework is explicitly falsifiable, with predictions for: gravitational-wave ringdown “coherence echoes, ” deviations from General Relativity time dilation in high-stress regimes, and observational bounds from early galaxy formation (JWST) and merger dynamics (LIGO/Virgo). This work constitutes a constitutive physical law, not an analogy: Gravity is not caused by mass alone, but by the loss of structural coherence relative to a reference geometric state. It unifies cosmology, gravitation, thermodynamics, and information-theoretic stability under a single dynamical principle, offering a new foundation for emergent time, cosmic structure, and vacuum dynamics.
