General relativity is a geometrical theory which postulates that the presence of mass and energy "curves" spacetime, and this curvature affects the path of free particles (and even the path of light). It uses the mathematics of differential geometry and tensors in order to describe gravitation without the use of gravity. This theory considered all observers to be equivalent, not only those moving at a uniform speed.
Its like listening to BBC America. I understand the words themselves, but not the meanings when you clump them all together like that. I have a sneaking suspicion that it pertains to math is some obscure way, of which I am phobic. Please don't hurt my brain like that again.
