Theoretical Foundations of the Domination of Dark Matter over Celestial Motion

Abstract

Recent advances in the study of celestial motion and classification have deepened people’s understanding of the theoretical foundations governing astrophysical structures, particularly within the framework of general relativity and dark matter. This paper systematically explores how the motion of celestial objects is influenced by the geometry of spacetime and the gravitational effects of non-luminous matter in a dark matter-dominated universe. By analyzing key observational evidence—such as galactic rotation curves, gravitational lensing, and the formation of largescale structures—the essential role of dark matter in maintaining galactic stability, regulating star formation, and driving cosmic evolution is established. Furthermore, the strengths and limitations of the prevailing ΛCDM model and alternative theories such as Modified Newtonian Dynamics (MOND) are critically compared. Although modified gravity offers an intriguing alternative, dark matter remains the most compelling component capable of consistently explaining a wide range of astrophysical phenomena. The integration of general relativity and dark matter into celestial classification not only enriches people’s understanding of cosmic architecture but also provides a foundational direction for future empirical and theoretical investigations.
