A Unified Theory of Cosmic Cycle and Celestial Evolution Based on the Chen's RG Dual-Field Mechanism ——With an Interpretation of the Underlying Physics of Observations by LHAASO and Auger

Abstract Based on the Gravitational String-Energy String (RG) dual-field coupling mechanism of the Chen's Superstring Theory (CST), this paper establishes a full-cycle unified model covering the nature of stars, matter dissipation of compact celestial bodies, black hole jets, ultra-relativistic inertial cosmic collapse and singularity restart. A star is an R-string energy cluster encapsulated by the G-string base field, with its energy originating from the overflow of antimatter inside and the annihilation of matter and antimatter. Due to the cessation of R-string supply, neutron stars, white dwarfs and black holes cannot form and sustain stable massive celestial bodies in their vicinity, and the residual matter gradually dissipates and returns to the base field. Under the extreme compression of the G-string, a black hole generates R-strings within the Planck scale; when the R-strings accumulate to a critical point and break through the constraint, a jet is formed, constituting a key link in the local cosmic cycle. When the R-strings in the entire universe are exhausted and the G-string becomes dominant, the universe undergoes an ultra-relativistic inertial collapse at a speed of 10^{35} times the speed of light. R-strings are re-excited inside the singularity and a cosmic genesis eruption is triggered, completing the cosmic cycle. This paper introduces the ultra-high-energy cosmic ray and gamma-ray observations by the Large High Altitude Air Shower Observatory (LHAASO) and the Pierre Auger Observatory, providing experimental support for the RG dual-field mechanism, black hole jets and extreme cosmic energy processes, and achieving a self-consistent unification of the microscopic string mechanism and macroscopic cosmology.
