The trouble with most flat earth vs ball earth discussions, and this post, is that EVERYTHING you said, works just fine in either model.
How does satellites operate, if they are not rotating around the flat earth? Even assuming the sattelites moves in circles above a flat earth, the math would change dramatically, millions of engineers working with GPS systems must be aware that the earth is not round.
When they changed from the earth being the center of the solar system to the sun being the center of the solar system, did any measurements change? NO.
Measurements on a globe and on a paper map is not the same. Map makers always have problems projecting world maps down on paper, ref this XKCD comic strip
I must admit that the errors in measurements on the flat earthers map in northern hemisphere may probably not be measurable by a common pleb like me (except when trusting the GPS), but on the southern hemisphere the differences are dramatic! Antarctica surrounding all the world? That makes no sense.
Ok, so one actually needs a special permit to visit Antarctica legally - maybe someone is hiding something secret there? I would not believe so, at least some tens of thousands of people have been visiting Antarctica, some with and some without a valid permit.
that's mad is that euphemism widely used in oslo!? I thought it was just a English thing, loving the usage though and I'm sure your not a common pleb me old fruit your analysis is spot on btw
