Oh, foo!  That is not a correct application of currently accepted
physical law.  There are already an infinite number of rotating
coordinate systems centered at every possible place; you just
haven't noticed them yet.  Am I moving faster than light in any
meaningful sense?  Has the universe blown apart yet?  Of course not.
Coordinates are an artifact, having no direct physical meaning.
