General Relativity is introduced a new framework for all of physics and proposed new concepts of space and time. It was Einstein’s stupendous effort to remove the restriction on Special Relativity that no accelerations be present, so that he could apply his ideas to the gravitational force. It is a measure of the difficulty of the problem that it took even the great Einstein approximately 10 years to fully understand how to do this. Thus, the General Relativity is a new theory of gravitation proposed in place of Newtonian gravitation.
