The Nature of Light's Force Property under the Framework of Chen's Superstring Theory: An Interpretation of the Entanglement Dynamics of Gravitational Strings and Repulsive Strings (Pure Text Version)

Abstract Based on the "Particle Discrete Dual-Domain Mechanism" of Chen's Superstring Theory (CST), this paper proposes that the essence of light is the unbalanced entangled vibration of gravitational strings (G-strings) and repulsive strings (R-strings) inside particles, which propagates as a force field by perturbing the uniform string network in space. The core conclusions are as follows: the frequency of light is uniquely determined by the entanglement and winding velocity of G-strings and R-strings, and its force property (gravitational bias/repulsive bias) is directly dominated by the dominant state of string entanglement—infrared light corresponds to the entangled state with dominant G-strings and exhibits gravitational properties, while ultraviolet light corresponds to the entangled state with dominant R-strings and exhibits repulsive properties. It is further revealed that the particle type determines the innate dominant state of string entanglement: free protons, with dominant G-strings, emit light biased toward the infrared band, and free electrons, with dominant R-strings, emit light biased toward the ultraviolet band, a characteristic that is prominently manifested when the Coulomb force is unbound. Combining existing observational data from experiments and phenomena such as light pressure experiments, comet tail phenomena, gravitational lensing effects, and bremsstrahlung, the self-consistency and universality of this theory are fully verified, and quantifiable experimental predictions are put forward, providing a new underlying mechanism for the unification of electromagnetic force and gravitational force.
