Betreen 1901 and 1904, Einstein published five papers on physics. In one paper he virtually proved the existence of molecules, solely by the use of theory; in another，he showed that light is both a wave and a particle. In his sixth paper published in the summer of 1905, he established the outline of his theory of relativity. His arguments radically revised existing concepts of electromagnetism, light, and that the speed of light is constant and that nothing in the universe can travel faster than light. If the velocity of light is constant, then all motion and even time itself must be relative to it. If objects could approach the speed of light, their age, mass, and size would appear very different to a stationary observer than if the objects were moving ,at slower speeds. A clock nearing the speed of light would slow down; if it reached the speed of light ，time would stand still. Many of his contentions, havebeen confirmed by subsequent experiments Atomiaclocks in spacecraft of biting the earth, for example,runa fraction of a second more slowly than clocks on eath.
