Emergent Gravitational Modification from a Coupled Fractional Field: Rotation Curves of 124 SPARC Galaxies Without Dark Matter
Abstract
We test a coupled PDE system with fractional Laplacian (α=1.2, fixed from EEG measurements) against NFW dark matter on 124 SPARC galaxies. The coupled PDE model wins 71% of galaxies (p=1.70×10⁻⁶) with median χ²/dof=0.789 vs 1.300 for NFW. Combined with prior results in EEG (r=0.767, p=0.010) and neutrino physics (Δχ²=4.20), this represents the fourth domain where α=1.2 produces significant results without domain-specific fitting.
