The special theory of relativity is an extension of that describes the motion and dynamics of objects moving at significant fractions of the speed of light.

In Einstein's original 1905 formulation, The postulates of Special Relativity are that

  • The Principle of Relativity is that the laws of physics are the same in every inertial reference frame.

  • The Speed of Light is the same in every reference frame.

In Special Relativity, the Galilean transformations are replaced with the Lorentz transformations, which form the Lorentz group.

An alternative formulation of Special Relativity is that of Minkoswski, which unifies space and time into . From the invariant squared infinitesimal spacetime interval, the Lorentz Transformations may be derived.
