Research on Vacuum Dynamics Theory

Based on the principle of the constancy of the speed of light and the phenomenon of light deflection caused by space contraction, this paper innovatively proposes the principle of relative change of the speed of light and constructs the theory of vacuum dynamics. This theory reveals the internal relationship between the space-time structure and the gradient of the speed of light, and provides a unified explanatory framework for the physical mechanisms of gravitational and dark energy phenomena. The core findings are as follows:1. In a vacuum, an object can also obtain an acceleration without the action of any external force, that is: , where is equal to the negative gradient of the square of the speed of light with respect to spatial changes.2. Based on the theory of vacuum dynamics, the Schwarzschild space-time factor in the general theory of relativity is successfully derived, and the prediction of Einstein's field equation is reproduced for the first time within a non-geometric framework. It reveals the intrinsically close correlation between the gradient effect of the speed of light and the phenomenon of space-time curvature, and interprets the physical mechanism of "space-time curvature is gravity".3. The space-time equation of a spherically symmetric object is solved, and this equation is consistent with the equation of the general theory of relativity. In particular, the gravitational field strength equation is obtained. This achievement reveals from the physical meaning level that there is no direct attractive force between objects. Instead, an object exerts an influence on other objects by changing the distribution of the speed of light in the space it is in.4. The hypothesis of a gradient distribution of the speed of light in the universe, decreasing from the inside out, is proposed, and relevant proofs are listed. It is pointed out that dark energy is essentially the internal energy released and converted into kinetic energy when celestial bodies move spontaneously towards regions with a lower speed of light.
