Yeah, General Relativity says that mass and pressure warp space-time and that
any particle being accelerated by no force except gravity will move in a
geodesic, that is, the shortest path between two points on the surface of a
warped object. The geodesic on the 3 dimensional surface of 4 dimensional
space-time at 93 million miles from the sun is the Earth's orbit.
However, neither Special, General, or any other theory I've heard of says
"The speed of light is whatever I make it".
