| contents | <p>The Hubble constant tension (~5-7σ) is the most persistent anomaly of the ΛCDM model. We show that this tension is a natural consequence of the XLG cosmology, where the speed of light carries a tiny anisotropy Δc/c = (1/137)² inherited from the primordial eccentric collision (ε=1/137). This anisotropy systematically modifies the light curves and inferred luminosity distances of Type Ia supernovae. When standard ΛCDM formulas (which assume isotropic light speed) are used to fit supernovae in the faster hemisphere (where Δc/c > 0), the recovered Hubble constant is biased upward by ~5.4 km/s/Mpc, yielding an observed H₀ ≈ 73.2 km/s/Mpc – in excellent agreement with SH0ES measurements. The Hubble tension is not evidence for dynamical dark energy or modified gravity; it is the shadow of a rotating, anisotropic light cone. Predictions for directional dependence of H₀, a dipole in distance modulus residuals, and anisotropic BAO scale are listed.</p> |
