Resolution of the Dark Matter Problem via Intrinsic Metric Time Dilation

The observed flatness of galactic rotation curves in the outer regions (halos) represents one of the greatest enigmas of modern astrophysics, leading to the postulation of Dark Matter within the standard model. In this work, we demonstrate that this phenomenon can be explained within the framework of the Intrinsic Metric Time Dilation (IMTD) theory without the need for additional exotic matter. We identify the galactic halo not as a reservoir of invisible mass, but as the geometric transition zone between the locally screened metric (N = 1) and the relaxed background metric of cosmic voids (N ≈ 1.12). It is analytically derived that the radial gradient of the scalar field in this zone generates an effective logarithmic potential, which enforces a constant orbital velocity (v ≈ const). This "Fifth Force" is the direct consequence of the relaxation of the time metric. The theory reproduces the phenomenological MOND dynamics as an effective limiting case and establishes consistency between local galactic dynamics and global expansion (Hubble Tension solution).
