Newtonian mechanics the field and force are acted between two masses and their relative linear distance, it is due to the gravity effect. In space-time geometry by space contraction, any particle escape velocity is required very high as a result, time dilutes, and the relative gravitational effect becomes reality. In classical mechanics, acceleration due to gravity is a continuous hidden action supposed to be associated with universe. It differs from energies in the space-time dimension in quantum mechanics. At the same time, the position and momentum accurately measure uncertainty by the Heisenberg principle is the relationship of mass, energy and wave nature. In this process de Broglie wavelength and materials momentum relationship is unified. Energy-mass entanglement in gravity space is like wave-matter entanglement. In this process, there may be a relationship developed between classical and quantum mechanics.
light would be a part gravity? Gravity force, F_G=GMm/R^2 =mg where, g = GM/R2 -(1); Gravity field energy, E_G=∫_R^∝▒〖F_G.〗dR --(2)
1/2 m〖V_esc^2〗^ -GMm/R=1/2 m0^(2 )-GMm/∝ =0
V_esc= √[GM/R]= c, velocity of light ---(3)
Schwarzschild radius, R=√[GM/c] ---(4)
Velocity of light is, c=GM/R^2 ---(5)
