1. First postulate (principle of relativity) The laws of physics take the same form in all inertial frames of reference.. 2. Second postulate (invariance of c) . As measured in any inertial frame of reference, light is always propagated in empty space with a definite velocity c that is independent of the state of motion of the emitting body.
In physics, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between space and time.In Albert Einstein's 1905 paper, On the Electrodynamics of Moving Bodies, the theory is presented as being based on just two postulates: [p 1] [1] [2]

where κ is the Einstein gravitational constant. [1] The stress–energy tensor T ab gives the matter and energy content of the underlying spacetime. In vacuum (a region of spacetime devoid of matter) T ab = 0, and Einstein's equation can be rewritten in the form (assuming that n > 2): =.
