A Novel Framework for Singularity Regularization and Quantum Gravity Unification via Higher-Curvature and Thermodynamic Corrections to General Relativity

I present a novel semiclassical gravitational framework that dynamically regularizes spacetime singularities through higher-order curvature corrections, thermodynamic contributions, and nonminimal couplings to scalar fields such as the Higgs. Unlike traditional approaches that rely on exotic matter, quan- tum discreteness, or extra dimensions, this model operates entirely within a four-dimensional, covariant setting and remains compatible with the Standard Model. The extended field equations are derived and solved—analytically in sym- metric spacetimes and numerically in early-universe scenarios—demonstrating the suppression of divergences in curvature invariants. Notably, the analysis shows that time can emerge as an effective, curvature-dependent parameter via nonlinear modulations of the scalar curvature dynamics. This framework yields concrete observational predictions, including: (i)suppression of high-frequency gravitational wave modes; (ii) anomalies in the low-ℓ multipoles of the cosmic microwave background; and (iii) favorable conditions for early black hole seed formation. These effects could be tested with data from LISA, CMB-S4, and JWST. In summary, this work offers a unified and falsifiable extension of general relativity, paving the way toward resolving classical singularities and bridging quantum gravity with observable cosmology.
