This is a new theory of relativity, which we call the theory of real relativity. The total energy of a system is made up of the inherent energy and the external energy. Each of these energies is associated with its own coefficient. These coefficients are distributed throughout the universe in space and time, providing symmetry and stability to every visible, invisible, living, and non-living, conscious and unconscious of the universe. Hence the inherent energy coefficient (G1) and external energy coefficient (G2) are responsible for the change of universe and nature.
