A theory based on two postulates: (1) that the speed of light in a vacuum is constant and independent of the source or the observer, and (2) that the mathematical forms of the laws of physics are invariant in all inertial systems. Implications of the theory of relativity include the equivalence of mass and energy and of change in mass, dimension, and time with increased velocity.
