I came across a video with "flat earth Dave" in it, and he was using concave hollow earth proof, to prove the earth isn't convex. Well, I suppose concave hollow earthers are being listened to by flat earthers, so our voices are not being completely ignored. lol
One last thing, it will be a complete circle when flat earthers switch to concave hollow earth view point, in my view, because flat earthers made me question the Heliocentric model, or at least wonder why flat earthers are crazy.
I like the sentiment here wolfwint, but some don't believe the earth is a planet. Concave Hollow Earthers believe the earth is the universe, and stars/heavenly bodies are all contained inside the earth. Anyways, you seem pretty balanced on your views. Enjoyed reading some of your posts.
