Some excellent work there, many additional observations.
But it's all muh refraction, ya know.
As I've mentioned, one of the surest ways to find truth is to always peform the thought experiment of ... pretending that you have the opposite position and then see if you can make a convincing argument on its behalf. Perhaps it's easier for me due to the sophistry of modern scholastic "debate", where you'd go into a debate tournament and in one round have to argue in favor of a certain proposition, and then in the next round argue against it.
But honestly considering the objections is actually the scholastic method in a nutshell. Those "objections" they dealt with weren't simply dismissed "after the fact", but the scholastics seriously considered the points made in the objections before arriving at their own conclusion, and had the objections won the day, they would have sided with those. We learn by considering the opposite arguments openly and honestly.
But you watch a video like that with yet another dozen independent observations that are simply impossible on a ball earth, and there's just nothing left. "muh refraction" is just utterly idiotic.
