Validation of the Higgs Quantum Gravity Theory HQGFT under Extreme Gravitational Regimes A Case Study of Sagittarius A Spin and Accretion Anomalies

This scientific treatise presents a comprehensive validation of the Higgs QuantumGravity Theory (HQGFT) applied to the supermassive black hole Sagittarius A*(Sgr A*). Utilizing a high-fidelity stochastic simulation framework with 10,000iterations, we analyze the fundamental interaction between electron spin and thelocal Higgs field density within the Kerr curvature. Results derived from the analysisof the S2 star demonstrate that a spin of a = 0.92 minimizes residual error (χ2 ≈1.20), providing unprecedented precision in modeling extreme orbits. Furthermore,the HQGFT solution to the low-luminosity jet mystery is discussed, and a temporalprediction for gravitational saturation during the imminent interaction with theMagellanic Cloud is established.
