Beyond Curved Spacetime_ A Resonance-Based Model of Cosmic Expansion

Main article Description: This paper challenges the ΛCDM model and the curvature-based assumptions of General Relativity by introducing a post-metric gravitational framework grounded in structured resonance. Rather than modeling gravity as spacetime deformation, we define it as phase compression in chiral resonance fields. We introduce the Phase Alignment Score (PAS) as a deterministic, falsifiable alternative to probabilistic tuning parameters (μ(z), η(z)), and show how this resonance-based system explains lensing, redshift patterns, and cosmic expansion without invoking dark matter or entropy inflation. The CODES model resolves key empirical tensions in modern cosmology through coherence logic rather than curve-fitting, offering a first-principles substrate that unifies gravitational structure, expansion behavior, and information collapse. Includes full PAS derivation, resonance simulations, and testable predictions for DES, Euclid, and JWST integration.
