If we were to put a flat-earther in a rocket and send them up to space, would they still believe that the earth is flat? Or would they just say that the windows of the spacecraft have screens on them? If so, would they be brave enough to open one of the doors/windows of the spacecraft while it is in orbit to prove that it is a hoax devised of clever CGI and green screens? This question is asking whether or not a flat-earther truly believes what they claim.
I don't think you would need to put a flat earther in a rocket to see if they would still believe that the earth is flat ?
(1) You could take them out to the middle of the ocean on a ship and ask them if they could see an infinite distance in all directions or if they could see just so far because of the thickness of the atmoplane and that would prove that there was no curvature of the earth ,prove the earth was not a globe , and that would prove the earth was flat ?
Or if they could always see land in the distance with a powerful enough telescope no matter how far at sea they were ?
And if they could see land, and especially the ice wall.....If they were close enough that they weren't obscured by the atmoplane ?
(2) Or you could ask them if they could not see more than a few miles in all directions because they could only see to a point where the sky and the ocean appear to meet at the horizon and that would prove that that the earth was not flat and there was a curvature of the earth and that would prove the earth was round and the earth was a globe ?
Or if they could see farther to the horizon the higher they went on the ship - from water line to main deck , to bridge, to crow's nest ?
Or if they could no longer see land in the distance with a powerful enough telescope after they had gone very far from the nearest
land ?
These tests are best perforned on clear, calm, sunny days at sea
(3) Or would they believe or admit what they saw ?
(4) Or they would say that they had been hypnotized or blinded to admit what they saw ?
(5) Or what they saw was just something that was projected there by NASA ?
