Zit was making the claim and I was clearly correcting the error of his claim and showing 'all the matter in the rest of the universe' has everything to do with geocentrism and that heliocentrists always ignore it.
You can't rationally claim that the curvature from universal gravitation is too small and then ignore the fact that the universal displacement is equally small. That is a demonstration of incredibly poor critical thinking skills.
The heliocentric choice to ignore the effect of the rest of the universe is a philosophical choice, not one driven by science.
"They also know that once you've done this, the mass of the Sun is the central dominant issue in determining the behavior of bodies in this solar system."
Only true if you make a philosophical choice unsupported by science that you can ignore the rest of the universe. Heliocentrists always do this because it's the only their model can work and geocentrists never do because there is no scientific reason to do so.
"Which there is ample evidence for . . . as you seem intent on forgetting to reply to!"
Not forgetting at all. It must be evidence uniquely supporting one model over the other before it has any relevance. This is something you do not have and seem intent on forgetting to reply to.
:-D
Well now, that is odd, I read back, and *I* can still see the posts by me to you specificallly about this.
Maybe your monitor has a smudge on it? A *big* smudge?
To repeat, just for you -- you observe with your eyes the moon's path thru the sky. Then we observe with our telescopes Earth and other planets path thru the sky.
This is observable evidence.
Then we do the math, and we notice that the equations work perfectly if we use the sun as the central gravitation pull that these bodies are moving around. We can even use these formulae to make predictions about where the bodies are going to be, and those predictions are borne out.
This evidence applies to any coordinate system you wish to use. The concept of 'the sun's mass as the central force holding the solar system together' is proven, by more empiracal evidence.
