Shortly after publishing his special theory of relativity, Einstein began to work toward creating an even more complete and far-reaching theory of space and time. It took him another decade, but eventually Einstein came up with an expanded and completely general form of his theory. The general theory of relativity was not only a theory of space and time, but also provided us with a deeper and more powerful way of thinking about the force of gravity
