Structural Gravity Theory v1.2: From Effective Metric to Quantitative Verification

Structural Gravity Theory (SGT) v1.2 presents a conceptual framework in which gravitation is interpreted as an emergent consequence of incomplete structural differentiation rather than as a fundamental interaction. This version establishes a unified parameter framework based on the structural parameters ηₛ (structural slip) γₛ (light-deflection parameter) βₛ (nonlinear correction) cₛ (structural wave speed) D_C (structural diffusion length) τ_C (structural relaxation time) with an explicit General Relativity (GR) limit. The framework introduces an effective metric derived from a structural potential, connects theoretical parameters to observable channels, and provides: Effective structural metric formulation Dual structural potentials Parameter-to-observable mapping Bayesian parameter estimation Parameter correlation analysis Numerical forward simulation Reproducibility framework Expanded falsifiability matrix Verification roadmap Future development roadmap All numerical values included in this repository are illustrative and intended to demonstrate the verification framework rather than fitted observational results.
