"When all is said and done, to insist that a non-c speed of light is nothing more than an artifact of a "nonphysical" choice of coordinates is to make a wrong over-simplification. When we wave goodbye to an astronaut who is about to make a high-speed return journey to the nearest star, it would be wrong to maintain that the slowing of his clock is nothing more than an artifact of a coordinate choice. It isn't: when the astronaut returns, he will have aged less than we have, and there's nothing illusory about that."I'm not sure what you want me to say. According to the conclusion, in the general theory the speed of light is not constant. Now I've run across evidence suggesting that the special theory is wrong.
Basically, sure, technically helio vs geo isn't "logically" any different, but the point is that we use a heliocentric model, and to use a geocentric one would be a very strange perception of the universe, from our point of view.
