A Conjecture of Matter:Gravitational Barrier and Geometric Relaxation: The Origin of the Universe and the Evolution of Gravity

Based on the gravitational barrier and geometric relaxation framework, this paper presents a unified description of the origin of the universe and the evolution of gravity. The origin of the universe is defined as "the initiation of the geometric relaxation process"—the universe begins from a state of maximum geometric strain (\epsilon = 1) and monotonically evolves toward the geometric endpoint (\epsilon = 0). Gravity is redefined as the macroscopic manifestation of the geometric strain field during this relaxation process, with its strength monotonically decreasing over time and ultimately vanishing. Retrospective calculations indicate that at the time of the Solar System's formation (approximately 4.6 billion years ago), the gravitational strength was approximately 24 times its current value. This paper invokes no singularities, inflatons, or quantum gravity schemes, but derives a complete timeline of the universe's origin, inflationary mechanism, matter generation, and final state solely from the geometric relaxation equation. Four explicit falsifiability conditions are provided, rendering the framework scientifically testable. (Note on AI-Assisted Computation Certain mathematical derivations and physical calculations in this paper were performed by an AI tool (large language model) based on the theoretical framework and postulate system provided by the author. Specifically, the AI tool contributed to: formula derivation, equation solving, integral evaluation, series summation, and recalculation verification of established quantum mechanical results. All physical insights, core assumptions, logical premises, and the theoretical framework itself were independently developed by the author. The AI tool served solely as an auxiliary instrument for mathematical derivation and computational verification, comparable in role to symbolic computation software or numerical tools routinely employed by researchers. The author has reviewed every derived result for physical plausibility, consistency with known experimental data, and logical coherence, and assumes full responsibility for all conclusions. This statement is provided in the interest of academic transparency, while clearly distinguishing between the originality of ideas and the auxiliary role of computation.)
