    Transmitting information (or moving a physical object - same thing) from place to place faster than C is banned. Moving the two places apart faster than C is allowed

    or, to think of it in a mind warping way (no pun intended)... When the universe expands, it's not that things are flying apart from each other, it's that the distances between everything are getting bigger.
