The LCM-Vacuum Phase Equation: Hydrodynamics of Vacuum Crystallization and Spacetime Emergence

We propose a unified field theory framework, identifying the cosmos as a hyper-rigid latticestructure evolving from a primordial superfluid. Central to this theory is the LCM-Vacuum PhaseEquation, which governs the crystallization kinetics of spacetime. By treating the speed of lightnot as a kinematic constant but as the characteristic elastic wave velocity of the vacuum medium,we resolve the logical disconnect between general relativity and quantum mechanics. This paperpresents the derivation of the governing equation and its implications for the thermodynamic originof the Big Bang and the geometric topology of the universe.
