At sunset in Denver, two people look at the sky directly above Denver. One is in Salt Lake City, where the entire sky appears to be light blue. The other is in St Louis, where the sky is dark all over, the exact same spot is black with stars. How can this be?
Just after sunset, we know the sun is still up there, just a little more distant. Yet if I look at the exact spot the sun would be in according to the faq, I see an unbroken field of stars, none are blocked by the sun or anything. They are much dimmer than the sun, yet something that is lighting up half the earth has disappeared. It can't be the distance, because I can see stars over the entire dome, so the relatively dim light of the stars can travel all the way across the dome. Why can't I see the sun when the stars are visible at even greater distance?
Why is the entire sky light blue all day, then suddenly over a period of 20 minutes it turns black. If the sun is still up there, just moving away, why the sudden darkness over the entire dome?
If one paints the dome black with stars over the night portion, and light blue with sun over the day portion, what would an observer see from the surface of FE? I see the entire dome all day and all night. Same dome, different place, sees the entire dome so different - day to night, southern hemisphere stars vs northern hemisphere.
When the sun sets, it appears to be directly on the horizon, apparently per the faq, it is still up quite a ways from the horizon. Why does the horizon appear to be in the same place all day, same horizontal angle consistent with the horizon in every direction. The light bends from the sun quite a bit to cause a > 20 degree distortion of position. Yet the light rays from the horizon right next to it are not bending? At that moment, the horizon looks to be at the same place as the sun. Are the rays from the sun bending > 20 degrees while the light from the horizon is traveling straight while the sunlight is bending? Or is the horizon moving up to the sun and both their light rays bending down to look lie they are on the horizon?
