It should be noted that, using the expanding universe interpretation, most scientists believe that there exist entire galaxies are moving faster than the speed of light relative to us.

Not saying I necessarily agree with the expanding universe, just giving an example of galaxies moving faster than c in mainstream science.

As far as the retrograde of planets, all of the gravity laws remain totally unchanged. All you have to do is transform the equations to use earth as the origin. The equations would probably be too large to write, but they would be mathematically equivalent.

I think the real argument comes down to the three ways of disproving this that I posted above.
