In 1889, he suggested that the Michelson-Morley experiment could still be explained in terms of the  speed of light depending on the Earth's motion through ether, by assuming that the measuring apparatus  had shrunk by the right amount to the give the illusion that the speed was the same.

His ideas were later  expanded on by Hendrik Lorentz, who developed a set of transformations which explained how the length  of an object changed when it was viewed by observers moving at different velocities.
