Research on Photon Mechanism, Blackbody Cutoffs, and Light Dispersion and Refraction Based on CST Chen's Superstring Theory (Draft Version)

Abstract This paper takes the static string force formula P=E(L-L_p) as the underlying dynamical foundation and adopts the RG dual-domain string element entanglement model to provide a self-consistent physical explanation for the physical nature of photons, the origin of the vacuum speed of light, the high-frequency ultraviolet cutoff of blackbody radiation, the low-frequency infrared cutoff (infrared catastrophe hypothesis), and the phenomena of refraction and dispersion in media. A photon is not a point particle but a macroscopic entangled light packet formed by the coherent superposition of a vast number of RG string elements; the propagation of light in vacuum is the chain-replication transfer of RG entanglement configurations on a G-string-dominated cosmic string network, not the spatial flight of a实体 particle. The vacuum speed of light is the result jointly constrained by the cosmic G-string substrate environment and the RG phase-transition critical condition, not an innate spacetime axiom. The RG entanglement frequency of a photon has upper and lower critical windows; beyond these windows, RG string phase transitions occur and the entangled structure disintegrates. This paper further presents two falsifiable observational predictions: that infrared photons are deflected by a larger angle than ultraviolet photons near massive celestial bodies, and that a spectral cutoff exists in the far-infrared band. This paper also marks the theory's untested status and existing shortcomings.
