Theory of Cosmic Collapse (TOCC): A Matter-Centric Alternative to Spacetime Expansion

The Theory of Cosmic Collapse (TOCC) proposes that matter contracts geometrically over time at rate S ≈ 4H₀, with space remaining constant. From this single premise, the framework derives radioactive decay formulas (tested on 249 isotopes across 24+ orders of magnitude), characteristic energies equal to exact combinations of the fine-structure constant α and atomic constants, a neutrino mass prediction of ~0.20 eV/c², and a mechanical explanation for gravity that resolves the hierarchy problem. This preprint establishes priority on the framework, empirical formulas, and predictions. Comprehensive isotope data tables are included.
