First-Principle Unified Theory of Light Strings: Complete Version & Supporting Papers

This work establishes a complete first-principle unified theory based on the light string as the only fundamental entity of the universe. From a minimal axiom system without additional assumptions, it rigorously derives: Lorentz transformation, time dilation, length contraction, and the constancy of the speed of light Newtonian gravity, Poisson equation, and the physical origin of gravitational constant G Einstein field equation and its correspondence to light string field dynamics Mass origin, Higgs mechanism, Planck formula, and mass–energy relation Unification of the four fundamental forces Cosmological constant Λ and Hubble constant H₀ This theory unifies special relativity, general relativity, quantum mechanics, gravity, and cosmology in a single self-consistent framework, providing fundamental ontological explanations for space-time, mass, force, and cosmic structure. All results are mathematically closed, experimentally compatible, and free of extra dimensions or free parameters.
