This study tests the no-dark-matter hypothesis, which suggests gravitational wave interference and Newtonian compression drive
galaxy dynamics without dark matter. A simulation of 200 galaxies in the Virgo Supercluster, using numerical general relativity in a 4D FLRW metric, compares scenarios with and without dark matter (NFW profiles, cluster halo 1.1 × 1015 M⊙). Parameters h ≈ 2.3 × 10−21 and K ≈ 0.35 are tuned using the Extended Virgo Cluster Catalogue. The no-dark matter model achieves 1–2% redshift accuracy but underestimates velocity dispersions (700 km/s vs. 900 km/s) and fails to produce flat rotation curves (60 km/s vs. 210 km/s for M100). The dark matter model yields 0.2–0.5% redshift accuracy, matches dispersions (890 km/s), and produces flat rotation curves, aligning with the cluster’s virial mass (7.4 × 1014 M⊙). These results support the necessity of dark matter
