Abstract

This submission presents Version 0. 1 of the Fluid Cosmic Crystal Theory (FCCT), establishing the foundational static framework that models the quantum vacuum as a macroscopic solid-state elastic lattice. Utilizing a renormalized Ginzburg-Landau potential, this initial model quantifies spacetime phase transitions driven by the topological defect density (p) and an effective phase order coefficient (₄₅₅). By mapping the critical percolation threshold (pc), FCCT v0. 1 successfully outlines a multicritical point where standard continuous geometry collapses. This framework provides a rigorous thermodynamic mechanism to resolve classical singularities via a transition to a superfluid vacuum phase, while phenomenologically modeling Dark Matter as the residual geometric strain of an amorphous, glass-like spacetime phase.
