Phase Coherence as a Unifying Principle of Physical Dynamics

Physical theory remains fragmented across classical, quantum, thermodynamic, and gravitational regimes despite deep mathematical overlap. This work proposes phase coherenceas a primitive organizing principle governing physical evolution. By formalizing dynamics as extremization of a global coherence functional over admissible phase states, classicalequations of motion, unitary quantum evolution, thermodynamic irreversibility, quantumnonlocal correlations, and probabilistic structure emerge without independent postulation.Gravitation is reinterpreted as curvature of a coherence metric rather than a fundamentalforce. The framework is explicitly falsifiable and forbids objective wavefunction collapse,fundamental time asymmetry, and point-like graviton degrees of freedom.
