The standard cosmological model, ΛCDM, currently faces a crisis of internal consistency, highlighted by the 5σ Hubble Tension, the S8 tension, and the existence of high-redshift massive clusters (“Pink Elephants”) that defy hierarchical growth predictions. This paper presents a comprehensive validation of the Modified Matter Acceleration - Dark Matter Free (MMA-DMF) framework. We perform a rigorous multi-probe analysis of seven extreme galaxy clusters: the Bullet Cluster (1E 0657-56), El Gordo (ACT-CL J0102-4915), Abell 520, Abell 2744, SPT-CL J2106, XMMU J2235, and MACS J0717. Operating under the strict constraint of Ωc = 0, we employ a scalar-tensor modification of gravity characterized by Adaptive Environmental Screening and Non-Linear Core Slip mechanisms. Our results demonstrate that the phenomenology of these systems—ranging from the lensing-gas offsets in collisional clusters to the premature mass assembly of high-z systems—can be reproduced without invoking non-baryonic dark matter. Specifically, we show that the “Ghost Peaks” of Abell 2744 and the “Dark Core” of Abell 520 are artifacts of scalar interference and geometric projection rather than invisible mass. We conclude that the MMA-DMF model satisfies Occam’s Razor, offering a more parsimonious and predictive solution to cosmic structure formation than the imposition of an undetectable dark sector.
