I've seen a lot of statements regarding Einstein's equivalence principle. Many formulate it to say that no experiment can distinguish between a reference frame in a gravitational field and an accelerating reference frame. But - isn't is true that in a gravitational field, tidal effects are present, while in an accelerating frame, no such tidal effects re present? Isn't this a dead giveaway as to which phenomenon is being observed? Is the problem merely a sloppy description of the equivalence principle? Is a more precise formulation that one cannot distinguish between the two ONLY in the context of an experiment involving a single fundamental particle? If so, ISTM that the principle is very limited in its applicability. If so, does this limitation have any profound implications? Am I being pedantic? Just complaining about fuzzy descriptions I've read in the popular literature? Where can I read more precise and accurate descriptions of the principle, its limitations and its implications?
