Scientific Prediction: Orbital Anomaly of Interstellar Object 3I/ATLAS

This paper introduces the Core Unit Density Gradient Theory (CUDGT-V2.5), a mechanical framework that replaces the geometric abstraction of spacetime curvature with a physical subquantal medium termed "Mother Space." By defining the vacuum as a high-density elastic lattice, we derive fundamental constants (c, G, h, alpha) and the proton-to-electron mass ratio with 15-decimal precision, eliminating the need for free parameters and gravitational singularities. To empirically validate this model, we provide a real-time orbital prediction for the close encounter of Comet C/2019 Y4 (ATLAS) with Jupiter on March 16, 2026. Contrary to General Relativity, CUDGT predicts a velocity-dependent coupling effect (\kappa = 1 + v^2/c^2), resulting in a specific cumulative positional shift of approximately 4.852 meters.
