Refuting the Flat-Earth theory

[Gawdzilla Sama]

I think the Southern Cross is an example what you can see once you go far enough south, while Polaris disappears at some point on that trip. Flat can't explain that.

If you are on the equator, you can see every star in the sky during some part of the year, even if some would always be so low they continuously kiss the horizon.   if you move with north or south, then increasing portions of the stars will remain forever invisible, forever at least on human life time scales.   The reduction continues until one reaches the poles, when only half of sky will ever be visible.

Yes.
