Abstract By introducing virtual 4th dimension to represent time in similar manner like 3 dimensions of space which can be measure in terms of length, the attempt is made to explain how velocity of the object in “Special Theory of Relativity” causes time dilation and how matter affects time in case of “General Theory of Relativity”. Same concept has been used to solve the “Galaxy Rotation Curve” problem and pioneer anomaly without need of any dark matter. Finally, it is shown that, increase in time affects gravity giving new definition to gravity based on which explosion of black hole and evolution of Universe is predicted.

Abstract This zero energy theory has great advantage over all other theories by its inner consistency due to which it can be used at microscopic as well as macroscopic level also. By using this theory, the attempt has been made in order to solve physics some mysterious unsolved problems like, dark matter, definition of space, expansion of the Universe and Gamma ray burst, origin of gravity, loss of mass and jets of black hole, curvature of space-time, equivalence between inertia and gravitational mass, difference in mass of proton and electron even having same value of charge, meaning of antimatter, the Universe with no anti matter etc. Thus, this theory can be used for unification of fundamental forces without need of any string i.e. no need of 11 dimensions, parallel universes, virtual particles like graviton etc.
