Lorentz–FitzGerald contraction(lŏ-rents fits-je -răld) The tiny contraction of a moving body in the direction of motion, put forward by H.A. Lorentz (1895) and independently by G.F. FitzGerald (1893) as an explanation for the result of the Michelson–Morley experiment (see ether). The contraction was later shown to be an effect of the special theory of relativity (1905).
