Einstein's theory of relativity consists of special relativity and general relativity, which are built on the principle of relativity and the local constancy of the speed of light. In these theories space and time became unified as spacetime. In general relativity, the concept that this spacetime could be curved was introduced. This curved spacetime replaced Newton's force of gravity and the source of gravitation.
