### General Relativity - University of Pittsburgh

Newton's theory: These motions are due the force of gravity deflecting the bodies from the trajectories they want to follow into the oscillations we see. Reinterpreted theory: the sheet of space-time displayed in the spacetime diagram is intrinsically curved. The trajectories followed by the bodies in free fall are simply the straightest lines ...
