Gravity is thought to be weak because it might escape into other dimensions. If it can leave, could it not also return? Consider a galaxy with a supermassive black hole in the center. From the perspective of General Relativity spacetime is curved in such a way that the center is deep in a hyper dimensional pit with a curved surface leading to the edge of the galaxy. Light is required to follow this curvature, however if gravity can leave and reenter spacetime there would be a shorter path to the edge. I.E. a straight line through hyperspace is shorter than a curve in spacetime. Has anyone else considered this?
