宇宙三论：时空、物质与引力的统一图景

This paper constructs a unified framework of the universe centered on spacetime, matter and gravity, systematically expounding the intrinsic correlation and evolutionary logic among the three core elements. Starting from the essential attributes of spacetime as the basic stage of cosmic existence, it analyzes the material distribution, motion laws and energy transformation as the core content of cosmic dynamics, and further clarifies the dominant role of gravity in linking spacetime curvature and material motion. By integrating the theoretical connotations of relativity, quantum theory and modern cosmology, this study attempts to break through the theoretical barriers between microcosm and macrocosm, depict a complete and consistent unified picture of the universe, and provide new theoretical perspectives and logical support for the exploration of the ultimate laws of the universe.
