river:
James R why did you initiate , by e-mail , for at least 10months , for me to come back .
I did not initiate that. See the detailed explanation I gave you last time you asked the same question. Have you forgotten? Or are you just trying to make busy work for me, like a troll?
This site is mainstream thinking to the of being point of science being authoritarian based . That is not good for science .
So vote with your feet. Why are you still here? Support sites that aren't "mainstream" or "authoritarian based" instead.
You came to us. We didn't come to you.
defend your claim that gravity is at the center of mass .
Point 1 here is that nobody seems to have made that claim in this thread. In fact, it's entirely off-topic for this thread.
Point 2 is that you haven't been clear what you mean when you say "gravity is at the center of mass", so it's difficult to work out whether that's a point worth defending.
Point 3 is that
if we can assume that you're referring to Newtonian gravity, then I honestly don't think you know enough maths to understand the proof, if I were to give it to you. Nor do I believe you're genuinely interested.
This is what happens when you don't post in good faith, river. People don't want to waste their time on you, after a while, because they learn that there is never any worthwhile payoff from doing that. It's not like you ever thank anybody for their help, or take on board what they teach you, after all.
And that all planetary bodies are moving towards the Suns center of mass . They are not .
You are correct that they are not, on average. That's what orbits are about. Planets go around the Sun, without falling into it.
Now, please post on the topic of the thread. If you don't want to discuss the topic, start a different thread or don't post.
