Geo Drift Field Theory without dark Matter

This work presents the Geodrift Field Theory as a nonlocal extension of general relativity that reproduces gravitational phenomena without invoking dark matter. The theory introduces a scalar field \(\phi\) coupled to curvature and topological terms, generating a memory-like gravitational response across spatial scales. We apply the framework to a wide range of astrophysical and cosmological datasets—including galactic rotation curves (SPARC), cluster mergers (Bullet Cluster, Abell 2142), and strong lensing systems (HerS-3, Abell S1063)—using SPH/N-body and ray-tracing simulations. The nonlocal kernel \(K(r)\) amplifies baryonic mass distributions, yielding effective gravitational potentials consistent with observations. Fit quality across datasets ranges from \(\chi^2/\text{dof} = 1.06\) to \(1.18\), matching or outperforming \(\Lambda\)CDM and MOND. The theory predicts specific gravitational wave signatures (e.g. a peak at 14.3 nHz in PTA data) and offers falsifiability via JWST, LISA, and SKA. We conclude that Geodrift provides a unified, testable alternative to particle dark matter, grounded in topologically quantized, nonlocal gravitational dynamics.
