Fitzgerald, Larmor and Lorentz shored up the collapsing ether-concept by showing-theoretically-that a moving body must contract slightly in the direction of motion, that a moving clock would therefore slow down. Though imperceptible except at speeds approaching light's velocity (186,000 mi. per sec.), these changes would affect a Michelson-Morley apparatus just enough to cancel any possible observation of the ether-drift-by altering...
