Representation of Gravity and the Intrinsic Property of the Gravitational Mass

The space-time structure of gravity mass is analyzed in this paper. It is proposed that "spin angular momentum and rotational angular momentum" are intrinsic properties of gravitational mass, and "curvature and gravitational effect" are representations of gravitational mass. The theoretical basis of the universal gravitation constant (G=1/16𝝿C) is found by studying the expression of gravity mass, and the curvature equation and time effect equation of gravity space are derived. In comparison with the experimental results of general relativity, The relative error of the calculated result of curvature equation of gravity space with the observation result of gravitational deflection of starlight near the sun are less than 8%, Otheres experiments were quite different. However, the intrinsic correlation of the gravitational redshift experiment of the γ radiation on the surface of the earth is consistent with the calculation results of the time curvature equation. The results of this study show that space curvature is the root of gravity. The propagation of gravity is the transfer of space curvature, and there is no "graviton" that transmits the gravitational interaction. Gravitational effects can be observed through supernova explosions and neutron star formation in the universe.
