Lol, this already looks painful. 8'' curve for every square mile. That patch should have a 266' linear curve to it. Does it mean earth is flat, no lol. How do you judge a curve of ice over miles without google lol. It stupid for a few reason. Most ppl don't understand the agruement let along the basic physics of light lol
The topic turns more into a debate about your actually range of vision and light refraction due to water. Our sphere acts like a convex lens. The camera debates lol, or the ppl using fish eye lens to prove anything at all lol. Ppl wasting time with flat earth.
You look into flat earth and you learn Nikon 900's are bad ass with a zoom attachment lol I can't see past the horizon but I can zoom it in lol
