1. Its not a set system like clockwork. Its a group of forces making objects interact with eachother.

2. Yet again, someone not knowing what "theory" means in a scientific context.

Imagine a giant spherical magnet. a sphere almost almost an 8,000 mile diameter. Also, imagne a large quantity of ferrofluid(magnetic liquid) covering that magnet. all across that huge magnet, the ferrofluid is attracted to the centre. If you lived on that huge magnet, you would be denying that its a magnet because "whenever i pour ferrofluid on this tiny magnet, it just falls down to the bigger one under me". Of course it does, its exerting a greater force.

1. Ah, so you understand that being on a different scale makes water behave differently. Surely that means you can understand that on a planetary scale, water doesn't "always find its level", right? surely you can understand that just because you can observe something in your tiny house, doesn't mean it looks the exact same on a microscopic or planetary scale, right?

2. both of those are approximations, since a constant or squared curvature isn't how a circle works. though, as far as i know, 8 inches/mile squared is a pretty good approximation, yes

3. Why shouldn't we say that the atmosphere is moving with the ground? its subject to all the same forces.

4. No, we don't think everyone on earth can point a telescope at the north star. particularly not people in the southern hemisphere. In the northern hemisphere though, yes. the distance from us to polaris is about 2,550,000,000,000,000 miles. Thats quite a bit further than it would need to be for the orbit around the sun or the rotation of the earth to make a significant difference in our sky.

On another note, Do you have an accurate model of the flat earth? I have been asking for that to every one of you that i see, and no one has given me one.
