引力的本质:空间复位力假说及宇宙学解释The Essence of Gravity: Hypothesis of Space Restoring Force and Its Cosmological Interpretation

Newton's law of universal gravitation and general relativity can accurately describe the laws of macroscopic celestial motion in existing gravitational theories, yet they fail to reveal the intrinsic generation mechanism of gravity itself. When explaining cosmic observational phenomena such as galaxy rotation curves and the high-velocity motion of the Milky Way toward the Great Attractor, unproven hypotheses including dark matter and dark energy have to be adopted to compensate for the theoretical defects. Combining the underlying logic of the Higgs field theory, this paper proposes an original hypothesis on the origin of gravity — the Hypothesis of Space Restoring Force. It states that gravity is neither an attractive force directly generated by mass nor a pure geometric effect of spacetime, but an elastic restoring force produced when space attempts to return to its flat and stable state after being distorted by matter. Based on this hypothesis, core cosmological phenomena including conventional gravitational effects, the stability of fast-rotating galaxies without disintegration, the high-speed movement of the Milky Way toward the Great Attractor, and the stable operation of equal-mass binary celestial systems can be uniformly explained without introducing dark matter and dark energy. This fully verifies that the hypothesis is logically self-consistent and formally concise, breaking through the limitations of existing theories and conforming more closely to the real physical essence of gravity.
