Dynamics of Light String Field and Reconstruction of Quantum Mechanics and General Relativity Field Equations Based on the First-Principle Unified Theory of Light Strings

Based on the complete axiom system of the first-principle unified theory of light strings, this paper carries out the underlying origin reconstruction and mathematical closed-loop derivation for quantum mechanics and general relativity, the two major cornerstones of modern physics. The full text completely retains the established theoretical framework, thoroughly breaks the ontological defects of traditional physical paradigms, involves no new axioms, no additional free parameters, no logical jumps, and no omission in any expression.This paper constructs a complete and self-consistent dynamic equation of quantum mechanics under the light string field, and completes the origin rewriting of Einstein field equations of general relativity in the light string field. It clarifies the physical ontology of wave function, spacetime curvature, quantization and gravitational effect, and restores all empirical constants, ambiguous physical quantities and mathematical fitting hypotheses to the intrinsic physical attributes of the light string field.It realizes the underlying global unification of quantum mechanics, general relativity, classical electromagnetism and thermodynamics, complements the last two core mathematical load-bearing walls of the light string theory, and completes the ultimate closed loop of mathematics and physical mechanism for the whole theoretical system.
