Just curious as to what hypothetical shape flat-earthers believe:
Whether or not it's circular, square or whatever, what happens if you travel in a straight line in any direction?
If spherical, you always end up where you started, perceiving all-along a "flat" (elevation-wise, not counting the ups and downs of hills and mountains, which cancel themselves out anyway) journey.
If flat,
1) there must be a point at which you're gonna notice a steep downturn as you reach the edge and begin to curl underneath
2) how thin is this pancake?
3) what's underneath? A dark world?
Been curious about this all-along.
