The theory of Relativity is based on time, space, and movement.was discovered by Einstein. It was because of an experiemnt with the stars. Using what he found he came up with general relativity, It was created by stars that were deflected by gravity. Distance and time are not absolute. If gravity is acceleration than motion has an affect on time and space. Gravity can warp affect time and space. This has been quantivitly comfrimed. The ticking of a clock depends on where your standing. (Lightman).

If it were not for Einstein, several decades might have passed before another physicist worked out the concepts and mathematics of general relativity, Lightman says.

Lightman, Alan. "NOVA | Einstein's Big Idea | Relativity (Lightman Essay) | PBS." __PBS__. 5 Feb. 2009 . This websites gives a lot of good information. They start from the beginning and work to the end. Something that is nice is that they have dates. Discussed are both general and special relativity. It is a creditable site because its used by teachers and all the information is there.
