That's what I thought. A lazy person who is brainwashed by textbooks and false teachers. That is why I didn't click on your links. I have done tonnes of research and know that there is NO curvature on the Earth (except through fish-eye lenses). You can see the Flat Earth from high altitudes, and distancewith the "supposed" curvature rate prove that there is NO curvature.
Cowards argue but never do the research, and Trolls just deny the truth. You are either one or the other.?
