Time and Gravity: A Coherence-Based Reconstruction of Gravitational Dynamics

Gravity is reformulated as a gradient in the gravitational coherence window τgrav(x). Spatial variation in τgrav induces coherence-gradient descent, producing effective accelerations that reproduce gravitational phenomena while grounding them in finite temporal coherence. A modified Schrödinger–Lindblad equation is introduced to incorporate gravitational decoherence, i ∂ψ/∂t = Hψ − [1/τgrav(x)] D[ψ], and the resulting acceleration emerges as a(x) ∝ −∇[1/τgrav(x)]. The model recovers geodesics through τ-equilibrium, explains gravitational time dilation, predicts deviations from general relativity for highly coherent quantum systems, and identifies τgrav ∝ √g00 as the temporal origin of curvature. The result is a falsifiable temporal-coherence foundation for gravitation.
