Re: "Curvature" proves nuthin!
"you're just confirming the curving effect of atmospheric gases at different presures, i.e., altitudes. You're correct, those pictures show that, which proves my point and very simple and basic physics. Optics is science, you know."
So how come no flat earthers have crowdfunded the cost of a cheap aircraft and flown to the edge the flat earth and taken photos or video to prove it yet? Gotta be cheaper than building rockets that only "prove" the "optical illusion".
