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_{\mu\nu}gμν,

• the stress-energy content TμνT_{\mu\nu}Tμν, and

• a structural deviation from a reference ground geometry gμν0g^0_{\mu\nu}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.
