https://www.metabunk.org/how-antarctica-debunks-the-flat-earth.t8175/page-2#post-196126 in post #55, you mention "the flat earth map"
In post 61, Rory replies that "there is no flat earth map." I think he is right. The one you sho is the one used widely, but it clearly doesn't work. Just look at Australia for instance. See how it is stretched east-west? As experienced by Australians in real life, the distance from west to east between Perth to Brisbane is around 2,225 miles. North to South from Darwin to Adelaide is 2,600 miles.A difference of about 15%
Yet on the map you show, the east-west distance is nearly 3 times that from north to south. The same problem shows up in the whole southern hemisphere For instance the flat earth map's Africa is less than twice as long as it is wide, while the real one is 5.5 times as long as its width.
Clearly the map you show makes no sense in the light of experience.
So where is the correct flat earth map?
Just one other question about your map.
Imagine standing at the southern tip of Africa and looking at the night sky to the south. Now travel to the southern tip of South America and do the same. According to your map, you are now looking up at arounf 90 degrees to the right of your South African viewing angle. Yet what everyone sees from these two positions is more or less the same stars, in the same pattern of constellations at any given time.
How could that be possible?
