Galaxy Rotation Curves under the Aperture-Well Unification Theory better than SM...

We test the Aperture-Well Unification Theory (AWUT) on three galaxies (F561-1, DDO 154, NGC 3198) using SPARC rotation curves. AWUT posits that flat rotation emerges from curvature tension in a unified spacetime-fluid medium, parameterized by a single geometric constant kappa. We analyze two regimes: Tier 1 (baryons fixed; 1 parameter) and Tier 2 (free global baryon scale s; 2 parameters). The AWUT velocity law v2(r) = s2v2 b(r) + 3πκr2 is compared against an NFW halo baseline (v200,rs; c= 10). Across all benchmarks, AWUT achieves higher accuracy and lower reduced chi-square with equal or fewer parameters. Error-floor, AIC/BIC, and robustness tests confirm that AWUT perfor- mance is not due to over-parameterization.
