Is there always the same "amount" of spacetime curvature in the uni.? Universe is what I meant by uni. Okay, if matter and energy cannot be created or destroyed, and since they are what causes spacetime to curve, does that mean there will always be the same amount of spacetime curvature occuring in the universe? I understand that large marterial bodies curve spacetime more than the small ones, but regardless of their size or distribution, is there always the same amount of gravity occuring in the universe? I am sure "amount" is probably not the best word, but I think you will understand what I'm asking.
