Research on Spacetime Traceability Contradictions and Dynamics of Mercury's Perihelion Precession

Modern physics takes the residual value of Mercury’s perihelion precession as the basis to establish the fundamental hypothesis of spacetime curvature. This hypothesis can only achieve mathematical fitting and logical closure within its own system and does not conform to the objective physical reality of the universe. A series of cosmological inferences derived from spacetime curvature including the Big Bang singularity, black hole event horizon and black hole jet keep showing irreconcilable internal contradictions. Based on the principles of the Theory of Light Origin, this paper confirms that the substrate of the universe is a constant three dimensional space and there is no unified cosmic time. The perihelion precession of Mercury is essentially a dynamic disturbance effect of multi body systems. The spherically symmetric gravitational force of the central celestial body cannot induce orbital precession and the disturbance comes from the chain gravitational compensation drag of adjacent celestial bodies such as Venus and Earth. This paper distinguishes the boundary between self consistency of mathematical models and physical reality and analyzes multiple underlying defects of the spacetime curvature hypothesis step by step to illustrate the origin of various theoretical dilemmas derived from this hypothesis.
