Standard cosmology assigns Sol a translational velocity of approximately 220 km/s relative to the galactic center, embedded within a Local Standard of Rest (LSR) framework derived from assumed large-scale galactic rotation. The Webb Mechanical Model (WMM) proposes instead that Sol drifts slowly within a stationary, conserved universe — not hurtling through space at near-relativistic fractions. This paper presents five independent empirical falsification tests of the velocity model drawn entirely from existing observational data: (1) the Voyager mission trajectories, (2) the encounter geometry of interstellar object 1I/‘Oumuamua, (3) the encounter geometry of interstellar object 2I/Borisov, (4) the observed near-symmetric geometry of the heliosphere, and (5) the precision transit detection paradox — the fact that exoplanet transits remain geometrically stable over multi-year baselines despite both observer and target stars supposedly moving at hundreds of km/s on independent trajectories. In each case, the 220 km/s velocity model predicts outcomes irreconcilable with observations, while the drift model predicts the observed results. No exotic physics is required. The falsification is geometric and mechanical.
