USP Field Theory — Galactic Age and Resonance Hierarchy

This publication extends the USP Field Theory framework into galactic-scale chronology. By modeling Δf-based spin-tension interactions and merger harmonics, it estimates the Milky Way’s field-age at ~4×10¹⁴ years—orders of magnitude beyond conventional 13.6 billion-year estimates. Version 2 includes: • Figure 1 — Galactic Resonance Hierarchy (10¹⁸–10⁵ Hz spectrum) • Δf sensitivity analysis and Gaia data cross-validation • Full symbol glossary and updated chronometric law derivations • Simulation method section based on spin-tension dynamics (F = T_f × (C₁×C₂)/r²) The study proposes a unified temporal topology linking atomic, planetary, stellar, and galactic resonance domains through Δf decay and field coherence.
