I can appreciate questioning the powers that be and all, but the earth is not flat. Two indisputable observations prove it:
1. You cannot see all stars from all points, and that's due to curve of the earth. From our perspective in the northern hemisphere, we cannot see the Southern Cross. And they cannot see northern hemisphere stars from the south. I have never seen a flat earther explain how this can possibly comport with their dome model. If you've ever visited a dome (like the Capitol Rotunda) you can see everything in it from any point under it. Look at any of the countless models of the so-called flat earth online. Pick a point - any point. Then ask yourself why you cannot see all the stars from that point. It simply does not make sense.
2. The apparent rotation of the stars is another easy objection to the flat earth model. When you observe the stars and trace them over the course of an evening, they appear to rotate counter-clockwise in the northern hemisphere and clockwise in the southern. Known as diurnal motion, this fits exactly with what you would expect from a sphere. It's not even worth exploring how different constellations of stars could appear to rotate in complete opposite directions under a dome.
Again, these are observations anyone can make with their own eyes. There is no room for CGI, fish eye lenses, NASA conspiracies, or the other usual litany of conspiracies flat earthers use to dismiss "globe earthers" out of hand. Sorry. Earth isn't flat.
