Short Summary: This software package provides the official numerical verification for the VIT Theory (v2. 6). It implements the universal coupling function (A) to demonstrate theoretical consistency across multiple astrophysical scales, offering an alternative framework to Dark Matter and a potential resolution to the Hubble Tension. Key Verification Cases Included: GR Limit: Consistency with General Relativity in Mercury’s perihelion and microscopic scales. Anomalies: Precise modeling of the Pioneer Anomaly (Case 3). Galactic Dynamics: Dark-matter-free solution for the NGC 3198 rotation curve (Case 5). Cosmology: Resolution of the H₀ tension with a predicted local value of 73. 0 km/s/Mpc (Case 6). Environment Effect: A unique prediction of a ~27% drop in gravitational lensing efficiency within dense cluster environments like Virgo (Case 7). Technical Note on Case 7: The simulation highlights the theory's non-linear sensitivity near the critical acceleration threshold ₀ = 1. 2 10^-10 m/s². This sensitivity is a fundamental physical prediction of the VIT field, where environmental perturbations from galaxy clusters significantly modulate gravitational coupling.
