Quantum Gravity Theory

This paper presents a novel Quantum Gravity Theory (QGT) that reinterprets the gravitational field as being derived from the Higgs field within a flat spacetime framework. Unlike General Relativity (GR), which attributes gravity to spacetime curvature, QGT integrates quantum corrections, nonlinear dynamics, and a variable speed of light
to describe gravitational phenomena [1]. The theory successfully predicts key cosmic phenomena such as the expansion of the universe [6], gravitational time dilation, and light deflection, while addressing discrepancies in observational data, such as the perihelion precession of Mercury and the nature of gravitational waves [4]. By calibrating the coupling constant λ, QGT shows potential as a bridge between quantum mechanics and cosmology, offering a new perspective on gravity that does not rely on dark energy or spacetime curvature.
