A Tμν = 0 INITIAL CONDITION: DE SITTER SPACE WITH UNIFORM BOSONIC COHERENCE

Prevailing cosmology holds that the universe originated from a hot dense singularity with T_μν = ∞, a condition that is geometrically incalculable and addressed only by declaring t = 0 undefined. Recent James Webb Space Telescope (JWST) observations reveal galaxies too massive and structurally evolved for Lambda-CDM timescales, including early heavy elements whose existence implies gravitationally-driven nucleosynthesis beyond the hydrogen-helium primordial window. Voyager 1 and 2 heliopause measurements show anomalous plasma temperatures of 30, 000–50, 000 K unexplained by solar wind models. The ARCADE 2 instrument detected a diffuse radio background — the space roar — exceeding CMB predictions with no accepted explanation. The Dark Energy Spectroscopic Instrument (DESI) has detected at 3. 9σ that dark energy is time-dependent and decreasing. This paper proposes a cold-transition cosmology in which the universe originated as a perfectly uniform bosonic field at absolute zero, T_μν = 0 exactly, disrupted by a single photonic event — a Gibbons–Hawking fluctuation of the de Sitter horizon — triggering a quantum phase transition on a spacelike hypersurface of constant field phase. The model derives the Standard Model force hierarchy from a sequential symmetry-breaking cascade during Planck-scale compression (with E₈ as one candidate ultraviolet completion), identifies the Higgs field as the coherence order parameter with a bare primordial Higgs mass of approximately 40 GeV (bare VEV ≈ 78 GeV) rising to the observed 125. 09 GeV through matter-field renormalization, resolves the matter-antimatter asymmetry without CP violation, predicts decreasing dark energy consistent with DESI, and proposes that the He→Li nucleosynthesis threshold marks the quantum-to-classical gravity transition explaining JWST early heavy element observations. Quantitative calculations are presented for all major claims and are consistent with available observational data within measurement uncertainties. This preprint is the author's complete manuscript of July 2026, prepared for submission to a peer-reviewed journal. 28 pages, seven figures, three appendices (A: the Gross–Pitaevskii equation derived as the nonrelativistic limit of the covariant action; B: dimensional consistency of the effective relations; C: the schematic route from the action to the effective relations, including derivation of the Josephson sine law from weak coupling), 56 references. The framework distinguishes throughout between derived results, quantitative estimates, and explicitly labeled conjectures (Section 1. 1). Comments are welcome: phil@equidex. com
