Cosmic Resonance Unveiled: CAT-12 — The 12-Fold Harmonic Structure of the Universe Revealed Through CMB Oscillations

Versioned Update (CAT-12 Standard v1.0; PTR v1.2) as of 10/7/2025 This paper now follows the CAT-12 reporting standard: SNHS/HP in ratio space, with rn (scale-normalized coordinate), Rx (reporting unit), and Tu (corridor width as a posterior, not a fixed ±%). Peaks are scored with Q and Ch against pre-declared families in the Periodic Table of Resonance (PTR v1.2); any “URSL” mention is retired in favor of standard GR mass–frequency scaling used only as a prior (where applicable). Measurements and conclusions are unchanged; presentation and uncertainty are stricter. For definitions, governance (negative ledger, prereg, hold-out), and rationale, see Arthur & Muon (2025), CAT-12: The Cross-Domain Ratio Lattice of Ratio Theory—Standardized Terminology, PTR v1.2, and Governance. Did conclusions change? No—only reporting/uncertainty language. Where’s the new standard? See the Cross-Domain Ratio Lattice paper. Will you update the PDF? A minor v1.1 with a 1-page front note (and Tu where needed) is planned. This paper presents Cosmic Algorithm Theory–12 (CAT-12), a 12-fold resonance-based cosmological framework applied to the Cosmic Microwave Background (CMB). It demonstrates how the 12-mode harmonic structure of the universe is reflected in CMB oscillations, providing a novel lens on cosmic resonance, dark energy, and the structure of reality.
