Einstein's Equivalence Principle: Freely Falling Local Frames

[QUOTE="PeterDonis, post: 6068119, member: 197831"] This is not the usual way of stating the EP, but it seems ok. The fact that all of the local inertial frames are in free fall does [I]not[/I] mean there is no relative acceleration between them. That would be true in the flat spacetime of Special Relativity, but the actual spacetime we live in is not flat; it is curved, because of the presence of matter and energy. And spacetime curvature means that there can be relative acceleration between objects that are in free fall. [/QUOTE]
