Based on the matter field theory, this paper proposes that the field generated by the basic moving units of matter (atoms, electrons) possesses both energyu2011conserving and informationu2011holographic properties, and propagates in vacuum at the speed of light. Within this theoretical framework, we classify all interactions in the universe into three fundamental modes: strong interaction (energyu2011exchange dominated), weak interaction (informationu2011exchange dominated), and nonu2011interaction (corresponding to dark energy). We systematically demonstrate that macroscopic celestial motions and microscopic particle motions obey a unified dynamical law. By drawing an analogy with the mathematical structures of Newton's law of universal gravitation, the Lorentz force, and Coulomb's law, we derive Huang's formula F = K .P1. P2 / R² for the gravitational interaction between cou2011moving celestial bodies. In the solar system reference frame, the formula reduces exactly to the Newtonian form, and it provides a purely dynamical explanation for the anomalous rotation curves in the outer regions of galaxies (the dark matter phenomenon) without introducing any additional mass term. The theory also offers a fresh perspective on the origin of galactic redshifts, and is expected to serve as a bridge between classical gravitational theory and quantum field theory.
