That bi-polar flat earth map to me is the dumbest representation of a flat earth. What holds the waters in? Why doesn't one fall off the earth?
Slight upward curvature of the bowl. Force field. Scrith. Pan-flat-earth-circumferential-current. Neutrino bombardment. Near the edge water interlaces with aether to form a rigid matrix. Pick your favorite.
You flat earth

supporters

really do have to dig deep to find
Curiouser and Curiouser hypotheses to prop up that
poor dying horse of the flat earth idea.
- Slight upward curvature of the bowl. And the air does escape over this "Slight upward curvature of the bowl"?
- Force field. You've been watching too much Star Trek and have lost the ability to distinguish reality from science fiction.
- Scrith Really and we flew through it with no trouble? Your magic ccrith can block 40% of neutrinos, yet allow ships and aitcraft free passage?
- Pan-flat-earth-circumferential-current. That would fling the water outwards and not keep it in, nect please!
- Neutrino bombardment. Really? Even your
scrith
lets 60% of neutinos through, so what effect is neutrino bombardment gpimg to have on water? Zilch. - Near the edge water interlaces with aether to form a rigid matrix.
I'd never thought of that!

Any more conjectures? Maybe a Globe really is a lot simpler and doesn't need all these crazy hypotheses.

I wonder why nobody thought of a Globe shape for the earth before.

Then we could travel in any direction without all these impediments getting in the way! I think I'd better start a
Round Earth Society!
One doesn't fall off the edge because one has never been there. If one had, one might.
One (many actually) have "been to the edge" in travelling by air and sea from Eastern Asia and Oceania to the Americas across the Pacific Ocean.
Here is that map:
While I support the UN map as far as explaining basic travel and circumnavigation, I believe that, in truth, the earth may be laid out in a manner similar to a dual Azimuthal Projection, this map:
On this model Antarctica exists as a continent. While there is still an Ice Wall, it is not Antarctica.
There are two celestial poles. One set of stars is rotating above the North Pole, and another set of stars is rotating above the South Pole.
And I didn't fall off the edge flying from Sydney, Australia to Los Angeles, USA.
Travelmath, Planning a trip? Let us do the math. tells us that:
The flight distance from Sydney, Australia to Honolulu, Hawaii is: 8150 km and the flight time is 10 hours, 38 minutes and
The flight distance from Los Angeles, California to Honolulu, Hawaii is 4125 km and the flight time is 4 hours, 55 minutes.
These times certainly seems to fit with our experience. Of course, we could not verify the directions of distances, but the 747s of the time we definitely not supersonic.
Now, we certainly did not fall off the edge and that total distance of 12,275 km seems quite impossible via any route on that map when we consider that its diameter must be close to 40,000 km.
