At night, I can see the stars over the entire sky. If the sun is still up there on the dome, why can't I see it? If the sun is still up there, why do I not see the beam shining down in the distance reflected of the dust in the atmosphere, like a spotlight beam? Why does whatever is blocking my vision of sunlight and sun block my vision of stars? How can the dome be filled with stars while the sun is Timestill up there and I see stars right through it, or it isn't up there?
Time zones would be pie shaped on a polar projection map.
FEs do not understand perspective and vanishing point. The words "vanishing point" holds great promise for FE explanations, but it is a artistic technique for making 3d objects look right in a 2d image. Google it.
As for limiting the distance you can see, everyone can see stars over the entire dome everywhere. This means you can see from one edge of the dome to the other. If you can see stars everywhere, you could see the sun everywhere.
