This study explores gravitational lensing through the TMB-TDB model, where thermomass bytes (TMBs) define curvature and permeability contrast governs light speed variations. Unlike traditional mass-based bending, lensing occurs due to byte field clearance in front of light. The model predicts lower lensing angles compared to General Relativity, aligning with observed expansion effects attributed to dark matter. The study validates these predictions using solar gravitational lensing, showing that permeability contrast and binder strength significantly influence space curvature and light propagation.
