Lorentz-Fitzgerald contraction. Artwork showing a sequence of tennis balls moving at different speeds,demonstrating the change in measured length (L*) from rest length (L) with velocities (v) close to that of the speed of light (c). At zero velocity,L=L* (left),while at the speed of light (right),L* tends towards zero. This change (along with time dilation) was explained in the Special Theory of Relativity developed by the Swiss-German physicist Albert Einstein (1905),but was first proposed by the Irish and French physicists George FitzGerald (1889) and Hendrik Lorentz (1892). The effect has been observed in particle physics experiments | |
