existence of ether to fit in the Newtonian concepts, but later on the theory of relativity abandoned the hypothetical ether and established the existence of relative space and time. Einstein's theory of relativity brought a revolution in the field of physics. The concepts such as 'the four-dimensional continuum of space and time', 'the relatedness of space with time due to the finite velocity of light', 'the effect of motion on the dimensions of space and time', have resulted from the special theory of relativity, and those of 'curvature of space owing to the mass of material bodies', 'non-Euclidean properties space', 'equality of gravitation and inertia', etc. are the consequences of the general theory of relativity. Nevertheless, the reality of space and time remains enigmatic in the field of science.
