Space - Relativity


A theory that consists of two theories, General Relativity and Special Relativity that explain how space time changes due to relative motion because the speed of light is constant regardless of relative velocity. When first published in 1905 and 1916, Albert Einstien' s Theory of Special Relativity and General Relativity, were ground breaking and had a profound effect on physics and astronomy. In particular it established the relationship between energy and mass with the now famous equation E = MC2 where E= energy, M= mass and C= speed of light.
