Moving space around also resolve the seeming impossibility of moving in two or more directions at the same time. Moving space upwards relatively means a body is falling downwards, at some point the body will experience free-fall, that is to say, no gravity. Alternatively, space compresses upwards, creating a region of high gravity upwards. This cancels with normal gravity downwards and the body once again experiences weightlessness. Both aspects are equivalent. The point is to move space about.
