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.
