I stated it earlier. The EP means gravity is locally indistinguishable from acceleration. How does one get from this insight, to "indistinguishable from coordinate system"? The latter is always true, must be true, if laws of physics are to exist. AG -- You received this message because you are subscribed to the Google Groups "Everything List" group.
