because even at very high altitudes it still appears to be a giant disc,
even pictures from space which i concede could be faked but they all seem to show a giant disc, and because the edge has never been reached and no ice wall has been discovered we must first assume that it is endless disc with the sun only shining on the known part of the world.
it would be great for a plane to fly south, but i fear it wouldnt reach very far into the unlit portion to verify.
This makes no sense at all. If it
looks like a disc, then it is not endless. The only way to see a shape is by seeing its edges. An infinite object cannot have a shape. Or, if it does, it could just as easily be a sphere with an infinitely gradual curvature such that, by any finite measurement, it is flat. But actually a sphere. Ha!
