That's right. In order to make his own theory fit with that of Newton's, Einstein began to research a new theory, and the answer to this was the theory of general relativity. This theory predicted that objects with large masses would distort the space surrounding them, making the objects nearby "fall" towards them. That is to say, Einstein discovered that space is curved, which means that even light is affected by gravity.
