there is no complete model yet. there is no complete round earther model yet, you still struggle with such a basic part of your fantasy as gravity, and you have the benefit of discarding reality and a multi-billion dollar budget behind it. why do you expect us to do fantastically well when everything we're taught are round earther lies?
most of your question is bs of the highest order. stars rotate around the central pole. if you curl the flat earth and contract the outer wall so that it meets at the south pole in your model, you will get the same basic movements. the aetheric whirlpool explains this. the only possible thing you could take issue with is how stars may become visible when they cross over what you call the south pole, or go near it. i suspect this is to do with the rush of pure aether closer to the edge of the world. it may carry light also.
ausgeoff, i have no intention of derailing this thread with why i believe the world is flat. if you want to ask, start another thread. this is not the time or place to explain the origins or proof of aether. you asked for the flat earth explanation, i have provide.d moving the goalposts is a bad habit. try not to do it again.
Please, there are plenty of threads about gravity and other subjects. I started this one to discuss celestial mechanics.
Research equipment worth billions of dollars is not necessary for observing and explaining the geometry of basic celestial mechanics, as they are observed over the earth whatever shape it might be; ancient people managed to produce a working re model before they invented paper. I'm not asking you to explain quantum tunneling theory, just the basic geometry & mechanics that we can observe with a naked eye.
Re: the bolded part: if you simply substitute the spherical earth with a flat one, the geometries do not work out the same, not even close; that is why I started this thread in the first place. If you hadn't yet realized that the mechanics do not work out the same over earths of different shape, I can only urge you to go out and start observing; that's actually very helpful for gaining understanding of the basic motions. And if there's a mythical substance, aether or such that by some mechanism makes it work out anyway I have not seen any detailed explanations of that phenomenon that have substance beyond speculation, so perhaps you could share.
Thus, especially as you begin with "there is no working model", your response is of the highest order bs. And ofc if your only purpose in posting is to be an asshole I'm sure there are threads in cn and angry ranting where you're welcome to express yourself.
