Abstract

The Unified Dimensional Cohesion Theory (UDCT) proposes that galactic rotation anomalies arise from a higher-dimensional bidirectional projection mechanism. This study extends the dynamic projection operator ΨBD(aN) to the complete SPARC rotation curve dataset of 175 late-type galaxies. The results demonstrate statistically robust gravitational lensing boosts in the low-acceleration regime (median boost factor 1.31, rising to +72% for dwarf galaxies), with a clear morphological dependence. These predictions are directly falsifiable with upcoming weak and strong lensing surveys (Euclid, Roman, JWST). This work (v2.4, June 3, 2026) presents a focused and detailed analysis of gravitational lensing predictions using the SPARC database. A broader integration of these results, including Hubble tension alleviation and preparation for CMB tests, is presented in v2.5.
