The new go pro 5 comes w 3 lenses. One is true one has a slight tail and one is fisheye . They run around 300$, 50$ balloon, 100$ GPS tracking unit. (GPS lol). Cheap way to know for sure..Not sure that would work.
I'm sure that fish eye lenses are used on go pros and such. I'm sure that makes the curvature look more than it is.
With a regular lense like used in the videos that show a flat Earth are more accurate. It just that they aren't high enough or show a wide enough view to get a good view of the curvature. If you really look at the videos of balloons showing flat Earth there is still a slight curve.
Things like a simple land or sea navigation course would let you know the Earth is round.
In the southern hemisphere different stars are used for navigation. For the same reason the further north you go the higher in the sky the north star is.
I'm old n have kids. So prob done with school although I'd love to go back.
