Albert Einstein's special theory of relativity is a scientific theory that explains the relationship between space, time, mass, and energy. Einstein first proposed the theory in 1905, and by the 1920s, physicists had widely accepted it. The theory is based on two postulates: The laws of physics are invariant in all inertial frames of reference. The speed of light is the same for all observers, even those moving with respect to one another. The theory also includes the formula e=mc2, which states that energy is equivalent to mass times the speed of light squared. One example of...

The relativity principle: The basic laws of physics are the same in all inertial reference frames.
The three unprovable assumptions of Galilean-Newtonian relativity. 1. The lengths of objects are the same in all reference frames. 2. Time passes at the same rate in all reference frames. 3. The mass of an object, as well as all forces, are the same in all reference frames.
The first postulate of special relativity. The laws of physics have the same form in all inertial reference frames. or There is no experiment you can do in an inertial reference frame to tell if you are at rest or moving uniformly at constant velocity.
The second postulate of special relativity. Light propagates through empty space with a definite speed c independent of the speed of the source or observer.
