1) Using the EP and the example of an accelerating elevator, it follows that light takes a curved path in space (not space-time). Wasn't this known by virtue of Newtonian gravity?
2) Assuming a geodesic is the shortest distance between two *spatial* points on a curved surface, does it follow from the EP that free falling bodies move on geodesics, and if if so how? 3) Concerning the above questions, how does "space-time" enter the picture since it seems the questions can be asked without referencing space-time.
