Re: The Mystery of Einstein's Postulates.
Re: Propagation of radiation in [OTHERwise] empty space.
Re: The German interpretation of translation is [OTHERwise] EMPTY.
Re: Einstein also infered [OTHERwise] "identical conditions" in his
mixing of frames @ DiFFERENT radii for the SAME GR TEST point-mass,
(of EARth, where he compares gedanken Polar & Equatorial pendulae).
[Clearly, if he had NOT meant "OTHERwise" there is NO distinction].
