Nope, a stupid question is a stupid question. The reason you ask it is because you can't understand the quotes I posted.
"I have an answer at the ready that explains the observation, all you have is trying to desperately hide behind coordinate system."
I just posted the answers. Particularly this one. You do exactly what George Ellis warns about.
"People need to be aware that there is a range of models that could explain the observations, Ellis argues. For instance, I can construct you a spherically symmetrical universe with Earth at its center, and you cannot disprove it based on observations. Ellis has published a paper on this. You can only exclude it on philosophical grounds. In my view there is absolutely nothing wrong in that. What I want to bring into the open is the fact that we are using philosophical criteria in choosing our models. A lot of cosmology tries to hide that.
Ellis, George, in Scientific American, "Thinking Globally, Acting Universally", October 1995
"The fact is that there are FORCES at work, not just motion, but FORCES that explain that motion."
Again, there is no physically-significant difference between a heliocentric solar-system and a geocentric universe according to Einstein, Hoyle, Born and Ellis.
"No force except for magical forces can explain your model, that is why you seem so apoplectic that I would DARE to ask such a simple and basic question."
You just keep demonstrating that you simply can't understand what has been posted in the statements by Einstein, Hoyle, Born and Ellis.
What force is capable of moving the massive Sun around a much less massive Earth while leaving the Earth motionless?
Keep going, no need to stop now...
A truck is heading into New York City at 80 miles per hour, that is a coordinate system.
An equally valid coordinate system would have New York City moving towards the truck at 80 miles per hour.
Either is equally valid AS A COORDINATE SYSTEM.
But an internal combustion engine explains the FORCES necessary to propel the truck towards NYC at 80 mph.
There is no equivalent explanation that you have provided that would supply the FORCE necessary to move New York City at 80 mph.
WHAT FORCE COULD MOVE THE SUN AROUND THE EARTH WHILE LEAVING THE EARTH MOTIONLESS?
Your inability to answer amuses me to no end.
Hmm, it looks like he isn’t distinguishing between the Sun orbiting the Earth, and the Earth being at or very near the center of the Universe.
