Theory of Relativity (Science Dictionary)

Theory of Relativity: Einstein’s ‘Theory of Relativity’ is seen as one of the most important scientific advances of modern time. Einstein recognized that the speed of light in a vacuum is constant, and an absolute physical boundary for objects in motion. For objects travelling near light speed the theory of relativity states that: objects will move slower and shorten in length from a point of view on Earth. Einstein derived the famous equation, E = mc2, which means that Energy is equal to Mass times the speed of light squared. In simpler terms, it states that there is equivalence between mass and energy.
