Analysis reveals Quantum Gravity Theory outperforms Newtonian dynamics and dark matter models in M87.
We apply the Quantum Gravity Theory (QGT) of gravity to the giant elliptical galaxy M87 using an extended velocity dispersion profile (0.5-100 kpc) to test its universality in a pressure-supported cluster environment. QGT has previously been validated across spiral and dwarf galaxies (NGC 6503, NGC 3198, DDO 154, and NGC 2903). QGT—grounded in graviton-antigraviton interactions—reproduces the observed kinematics without dark matter or parameter tuning, deriving its transition scale ( = 23.6 kpc) solely from baryonic mass. Key results demonstrate: 1. Statistical Dominance: QGT achieves the lowest BIC score of -16.4, decisively outperforming Newtonian dynamics (BIC = 132.8), MOND (BIC = 78.5), and NFW dark matter halos (BIC = 42.3) with ΔBIC = 58.7 against NFW and ΔBIC = 94.9 against MOND. 2. Virtual Mass Amplification: Antigraviton-mediated effects generate scale-dependent mass amplification (reaching 2.64x at 100 kpc), eliminating the need for particle dark matter. 3. Kinematic Fit: 85% reduction in RMS residuals vs. Newtonian dynamics (7.3 km/s vs. 52.4 km/s), with errors ≤5% across all radii. These results extend QGT's validity from spiral/dwarf galaxies to cluster-anchored ellipticals. Future gravitational-wave missions (e.g., DECIGO/BBO) could test its cosmological extensions.
