Encyclopedia > Space contraction

Relativistic effect of apparent contraction of coordinates of moving reference frame in the direction of motion when seen from non moving refernce frame. Results mathematically from Lorentz transformations. Albert Einsteins theory of relativity is a set of two theories in physics: special relativity and general relativity. ... The Lorentz transformation (LT), named after its discoverer, the Dutch physicist and mathematician Hendrik Antoon Lorentz (1853-1928), forms the basis for the special theory of relativity, which has been introduced to remove contradictions between the theories of electromagnetism and classical mechanics. ...


Also known as Lorentz contraction.
