Special relativity. Special relativity is a theory of the structure of spacetime. It was introduced in Einstein's 1905 paper On the Electrodynamics of Moving Bodies (for the contributions of many other physicists see History of special relativity).
What causes Gravity? One of Einstein's old tutors, a man by the name of Minkowski showed that the special theory of relativity could be expressed in an interesting way. The world we live in consists of four dimensions, the three space dimensions and one that is not exactly time but is related to time (it is in fact time multiplied by the square root of -1). This is not at all easy to understand but it means that space-time as we call it has some rather weird properties.
