Refuting the Flat-Earth theory

[FlatAssembler]

Well, like I've said in the OP, Flat-Earthers generally claim there is no dip of the horizon. They don't provide a word-sallad explanation for it, they simply deny that it exists.

Correct. So, what is the point of trying to educate people who have made it clear than any and all evidence you provide will be rejected?

Not 'refuted', mind you - rejected.

Like I've said, maybe many Flat-Earthers are simply unaware of the dip of the horizon. Maybe they are simply unaware of that you can easily measure it from an airplane using any modern mobile phone (with a camera and a gyroscope), like I was. Maybe they honestly don't understand the "You can see the sunset twice if you watch it sitting down and then quickly stand up." argument, like I did not.
