Spacetime curvature and the force pulling an object "down" the curvature
ok , I have a question about the current model of gravity.
If mass bends spacetime I understand that it accounts for things like how long light takes to travel through its geodesics but "why" does this curvature make objects fall towards the centre, I am having troubles wording my question, pretty much in a vacuum an object (near no other large masses) will not roll down a ramp so why does the curvature of the spacetime arround a massive object pull things inwards, i don't see how just the curvature of the spacetime arround it is enough to do this
