:Chuckle: Yes, if we could just show that spacetime is a perfect representation of reality then we would be confident that what ever causes spacetime will be the cause of gravity. However if the precision of the correspondence between the mathematics of spacetime and reality is not perfect, then spacetime still is the best we can do to predict the motion of objects but it is not the cause of gravity. I just mentioned that correspondence in this post: http://www.sciforums.com/showpost.php?p=2350367&postcount=7 If you were to reply to this could I suggest that you join that thread since I am the originator?
