In physics, the theory of special relativity generalizes Galileo’s principle of relativity—that all uniform motion is relative and that there is no absolute state of rest. Though physicists Hendrik Lorentz and Henri Poincaré had made contributions to the theory already, Einstein provided a radically new interpretation in his 1905 paper “On the Electrodynamics of Moving Bodies.” In it, Einstein redefines the concepts of space and time and abolishes the concept of “aether,” which is what? _to_Puerto_San_Jo.jpg)
