Special relativity and general relativity are two theories proposed by Albert Einstein, a man widely regarded as the greatest genius of the twentieth century. He proposed the theory of special relativity in 1905. According to this theory, in simple terms, motion is always relative and there is no absolute frame of reference. It also states that the speed of light (in a vacuum) is a constant and it is the same from all frames of reference. This theory does not talk about gravity. This theory relates space and time, through motion. This theory has been shown to be true by experiments involving the slowing down of clocks in motion versus stationary clocks.
The theory of general relativity was proposed in 1915. This theory incorporates gravity and predicts a warping in space-time due to strong gravitation fields in the vicinity. For example, the bending of light near massive celestial bodies have been observed. This theory incorporates the equivalence principle, according to which accelerated motion and a state of rest are identical. Evidence of this is the change in weight we feel while riding in an elevator.
Hope this helps.
