I would like to know about this: Is there a limit to how much spacetime can warp? If there isn't, can there be? If we imagined an isolated object in the universe, how much would it warp spacetime per 1 cubic meter if it had the mass of 1 kg. No other gravitational forces are acting on this object. So how much wuld it warp it?And also, is there a chance that spacetime might have potential energy. It has the potential to curve. Is there a thing in GR that strictly says: No! There is NO potential energy in spacetime?
