Lunarsystem

What if we live in a lunar system, where the earth, sun and planets orbit the moon?
Perhaps the moon is the largest body in the lunar system, the sun goes around the earth, while the earth and planets go around the moon.
Why was the sun selected to be the center, why not the moon, or the earth?
Perhaps the center is a piece of empty space, or an invisible something or other.
We may call such a system a nihilsystem or a mystisystem.

See tycho brahe and coppernicus.

You can bang out math for any object being the center of our system. But the sun is the only model that isn't obscenely difficult to solve for.

Also look up what a barycenter is. It's kind of pedantic to say but the sun isn't "exactly" the center of our system.

I don't know if that's the case, I'll have to look into it.
But even if that's the case, what do you mean by solve for?
Do you mean other models are less predictive/accurate, or do you mean they're equally predictive/accurate, but more complicated?
If they're just more complicated, that doesn't make them less probable, why should the cosmos prefer simplicity to complexity, to soothe men's minds?

There was a geocentric model. It had some predictive power. I don't know if it rose to the level of the heliocentric one.

Whether simplicity, predictive power and explanatory power equate to truth? Well to me that's a question for philosophers. To be honest I'm not entirely sure what truth means. It does seem to imply absolute certainty which is something I believe is beyond us mere mortals.

Gravity is related to, and depends on, the mass of the body: the sun comes first, then earth, then the moon.

Back in the old days, people used the geocentric model, which they made extremely accurate (but was a pain in the but to solve problems.in) then capenicus came along and introduced then heliocentric model, which was just as accurate. But much much easier to do math on. If you want to make the moon the center of the solar system, making predictions would be an absolute nightmare, but it could work.

Did you get a funny feeling in your pants when you posted that?

If you want something a bit more adult, search crash course astronomy on YouTube. It was probably answer most of your questions.

Yes!

That's pretty sad actually.

Maybe for you; I don't care much: as you know already, I don't understand Internet.

No, no! You are targetting the wrong age group, try http://www.physics4tiny_tots.com/files/motion_gravity.html

Anyway, OP-wise, the problem isn't just solving equations, it's explaining them in a physical sense. Mathematically, you can take any point to be stationary and take everything to be moving around it, but scientifically you need to be able to explain where that motion comes from. In the heliocentric case, we have gravity.
In the geocentric case, we ran into a problem with the movement of the other planets:

That's the path they appeared to take if the Earth was stationary. In the heliocentric model, it's explained by all the planets moving essentially in concentric circles (to simplify), and occasionally passing one another.

Trying to make a lunar-centric model would no doubt run in to something similar. You can crunch the numbers for it theoretically just fine, but can you explain why any of it happens?
