This paper proposes an alternative cosmological model to the standard inflationary singularity, postulating an initial state of Absolute Zero Vacuum as a metastable potential energy system. It is hypothesized that universal genesis occurred through a stochastic nucleation event—the spontaneous emergence of a fundamental atomic structure—which disrupted local thermal equilibrium. Instead of an instantaneous radial detonation, we describe a mechanism of lateral thermal propagation, analogous to a chain reaction or phase transition in supercooled fluids. In this model, the expansion of the universe is reinterpreted as a wavefront of latent heat, transmitted via adjacent kinetic contact, converting static vacuum into dynamic matter. Furthermore, the model offers a structural explanation for supermassive bodies (Black Holes), defining them not as gravitational singularities, but as extreme density nuclear aggregates formed by rapid coagulation during the initial expansion phase, characterized by the absence of external electron shells due to gravitational pressure. This approach seeks to unify classical thermodynamics with the origin of baryonic matter.
