Abstract:
We propose an extension of Refractive Vacuum Gravity (RVG) embedded in the 14-dimensional holographic geometry of Geometric Unity (GU). This framework reinterprets galactic dark matter as a modulation of the quantum vacuum's refractive index while retaining a cold non-baryonic component—dark Spinorial Matter from GU's chiral Weyl branching—to satisfy cluster and cosmological abundances (Ω ≈ 0.26). The vacuum modulation, sourced by a scalar dilaton linked to the 95.4 GeV diphoton excess (3.1σ ATLAS+CMS), couples to the electromagnetic sector through the trace anomaly to generate a Gordon optical metric. Confronted with the 175-galaxy SPARC sample using Spitzer photometry, this refractive halo decisively outperforms standard models, achieving a median χ²/dof = 0.72 (vs. 1.38 NFW, 3.24 MOND) with a Bayesian preference of lnℬ(RVG/NFW) = +929. To resolve structural anomalies like the Bullet Cluster, we introduce a two-field TeVeS-class completion where macroscopic flavor oscillations of the spinorial dark matter induce a quantum kinetic pressure, forming a solitonic core. Cosmologically, this joint Refractive-Spinorial model fits the CMB acoustic peaks, alleviates the S₈ tension (S₈ ≈ 0.77), and explains the Koide lepton-mass ratio deviation via a 1-loop dilaton shift. Validated via a Hierarchical Bayesian Model, this theory offers a comprehensive multi-component dark sector, predicting frequency-dependent S₈ suppression and null results in direct searches.
