Higgs–Gravity Cosmology

We propose a Higgs–Gravity Cosmology in which the Higgs field couples non-minimally to curvature, modifying Einstein’s equations through an effective Newton’s constant and horizon stability conditions. Applied to the Friedmann–Robertson–Walker metric, this framework yields generalized Friedmann equations with an entropy source term associated with black hole horizons. Entropy growth from primordial and supermassive black holes plays a central role in cosmic evolution, driving early structure formation and shaping the expansion history without invoking dark energy or inflation. The model offers a unified perspective on several open problems: curvature-induced corrections to Higgs decays can account for the observed matter–antimatter asymmetry, primordial black holes seeded during the Higgs-dominated plasma epoch provide a pathway to the early appearance of supermassive black holes, and entropy injection at black hole horizons contributes to the Hubble tension. Observational consequences include a reinterpretation of the relic neutrino background, with high-energy neutrinos already detected by IceCube and ANITA favoring this framework, percent-level anomalies in BAO residuals, and FRB energetics tied to the PBH mass spectrum. Crucially, the framework is minimal, introducing no new fields beyond the Higgs boson, and it makes falsifiable predictions testable by upcoming surveys (PTOLEMY, DESI, Euclid, CMB-S4, SKA). If supported, Higgs–Gravity Cosmology would represent a viable alternative to ΛCDM and inflationary models, with entropy growth as the fundamental driver of structure formation and cyclic cosmic dynamics.
