Foundations of Thermal Spacetime Dynamics

This preprint presents the dynamical foundations of the Thermal Spacetime Unification (TSU) framework, in which time is treated as an emergent physical quantity governed by thermal gradients rather than a fundamental background coordinate. The work formulates the laws of temporal motion, introduces the concept of effective temporal inertia, and derives a causal field equation for thermal–temporal propagation consistent with relativistic locality. The framework reproduces known astrophysical residuals without parameter fitting and provides a unified dynamical basis for previous TSU results.This work is also archived on Zenodo (Version 4.0): DOI: 10.5281/zenodo.18396867
