Another couple of issues, Manarg.
under the theory of electromagnetic acceleration, the primary experiment that many flat earthers claim is the proof of the flat earth - that is the Bedford Levels experiment - becomes null and void, as light was assumed to be travelling straight. I have been shown no documents proving or trying to prove the existence of flat earth through evidence, while assuming that light bends.
Additionally, observers in the southern hemisphere observe the sun rising and setting, from the east to the west, but the path of the sun along a circular equator about the north pole does not take the sun anywhere near east or west of any location south of the tropic of Capricorn.
