Internal Temperature Distribution, Rotational Evolution and Energy Source of Geological Activities of Celestial Bodies under Light String Theory——A Universal Unified Interpretation from Earth to Stars

Based on the first principle unified theory of light strings, this paper systematically derives the distribution law of light string field density inside celestial bodies and reveals the genuine internal temperature distribution mechanism of celestial bodies. Material accumulation displaces free light strings in the surrounding space, resulting in the lowest light string field density at the center of a celestial body. This reduces the local time flow rate and particle evolution speed, which means the core temperature of a celestial body is the lowest rather than the highest. The maximum temperature occurs at the region with the highest light string field density, generally located at the bottom of the mantle or convective layer, which also forms the gravitational lens focal point of the celestial body. Taking the Earth as the research object, this theory predicts that the highest internal temperature exists at the core-mantle boundary at a depth of approximately 3000 kilometers, which is highly consistent with the geological observation results of magma generation areas and mantle plume roots. For the Sun, its core temperature is far lower than the value predicted by traditional models, and the maximum temperature is located at the bottom of the solar radiative zone. From the perspective of the interaction between light string field and macroscopic moving objects, this paper proves that all translational and rotational motions of macroscopic objects squeeze the front light strings and produce net energy dissipation, which inevitably slows down celestial rotation. This provides a first-principle explanation for the long-term deceleration of Earth’s rotation, independent of the traditional tidal friction mechanism. Furthermore, this paper explains the sustained dynamic source of celestial rotation based on the vortex driving mechanism induced by the radial gradient of the light string field, and demonstrates that the energy of geological activities including earthquakes and volcanic eruptions originates from the continuous energy convergence at the focal point of the light string field. This study establishes a unified, logically self-consistent fundamental framework for the internal physics, rotational evolution and geological activity energy of celestial bodies, and puts forward multiple verifiable scientific predictions.
