Unified Cosmic Mechanics Evolution Theory (VIII) Single-Particle High-Speed Dynamical Effects and Their Relationship with Relativity

Based on the momentum unit evolution theory, taking the time update mechanism, the velocity increment formula, and the four covariance principles as the premises, combined with the special relativity window compression, Newtonian gravity, and path bending perception multiplication effects, this paper reconstructs the gravitational lensing, red-blue shift, and Schwarzschild radius systems. The study confirms that gravitational lensing is the dynamical trajectory of ultra-high-speed particles under the synergy of the three effects; special relativity is essentially the result of dual compression of space-time windows, which leads to extremely weak gravitational interaction of particles and can only be manifested with the support of supermassive celestial bodies; the Schwarzschild radius is the critical value of momentum field density capture, which does not depend on the Einstein field equations. The paper further reveals that both photons and neutrinos have mass, which is essentially the number of momentum units (total number of evolutionary carriers). The conclusion is clear: when a single particle moves at high speed, the compression of the perceptual window and the topological structure together inhibit gravitational interaction, and only supermassive celestial bodies can break this limit to manifest gravitational effects.
