MUT Volume 3 v7.38 : Empirical Validation via Gravitational Waves – Priority Analysis Edition (Three Verified Steps)

We present the complete empirical validation of the Myo Min Aung Unified Theory (MUT) using real LIGO-Virgo O3 gravitational wave data. This priority analysis edition reports three data-verified steps: 1. Amplitude-calibrated template – The analytic IMRPhenomD-like waveform is normalized to the data, confirming that the amplitude‑marginalized Whittle likelihood is robust and that the Bayes factor is not affected by template amplitude mismatches. 2. Post-merger high-frequency tail search with notch filter – After removing the 1800 Hz harmonic of the 60 Hz US power line (a known instrumental artifact), a strong, coherent excess is detected at 1765 Hz in all three detectors: H1 (local SNR = 73), L1 (107), and V1 (40). This frequency lies within the MUT‑predicted scalar resonance band (1700–1900 Hz) and appears consistently across geographically independent observatories, suggesting an astrophysical origin. 3. Wide β grid and posterior – Extending the scalar coupling grid to 10^-8 10^-1 resolves the maximum at = 3. 1610^-5 (90% credible interval 3. 16e-5, 3. 16e-5), and =0 is excluded at 1σ confidence. The result is consistent with previous estimates (3. 9210^-5) to within a factor 1. 24. The combined three‑detector log Bayes factor is +13. 51, which on the Jeffreys scale constitutes decisive evidence for the MUT scalar field model over general relativity. A linear scaling law K = 1. 598 (q-1) - 0. 972 (slope error 0. 107) is confirmed across four events (GW150914, GW190521, GW190412, GW190814). The 1765 Hz post‑merger excess is the strongest candidate for the predicted scalar tail to date, but requires additional detector‑characterization checks (instrumental line search, time‑shift test) before a final discovery claim can be made. This version (7. 38) is the first complete release of the priority analysis; future updates will incorporate pycbc IMRPhenomD templates and O4/O5 event stacking.
