Theory of Relativity, The By Bradley, Adam James
The Theory of Relativity is the name given to two separate theories put forth by Albert Einstein (1879–1955): ‘Special Relativity’ and ‘General Relativity’. When first published in 1905, Einstein’s ‘Theory of Special Relativity’ upended Newtonian Mechanics and was in agreement with James Clerk Maxwell’s equations of electromagnetism. The theory opened up new avenues for particle physics and is thought to have ushered in the nuclear age. Relativity was also used to predict the existence of black holes and other cosmological phenomena. Special Relativity, Einstein’s theory of small particles, includes possibly the world’s most famous physics equation: E=mc², which predicts the relationship between mass and energy where energy is equal to the mass of an object multiplied by the speed of light squared.
