Thanks.
I find that the first obstacle to my reviewing the Wiki is the lack of a clear flat earth theory. For example, I am reviewing the article
https://wiki.tfes.org/Erathostenes_on_Diameter. I would like to discuss it rigorously. But I find I am handicapped by limited information about the flat earth. Let me ask a few questions pertinent to that article:
1. Is the flat earth flat? In other words, on a clear day, can I see from a point 6 miles above sea level at any point on earth to a point 6 miles above sea level at any other point on earth? (I chose 6 miles because Mount Everest is 5.5 miles above sea level).
2. Is the sun (or anything else) generally in the direction it appears to be? In other words, are effects like refraction negligible in atmospheric observances like that of Eratosthenes?
3. Is the FE sun some distance considerably less than 93 million miles away? And I suppose it is not too impertinent to ask the exact range of how far away the sun is (though in my FE naivete I would expect the height of the sun to be the very result of the Eratosthenes experiment once we consider it more rigorously)?
4. Generally speaking, is there a flat earth theory that will predict exactly where (lat, lon, elevation) the sun is at any given moment? In other words, is there a flat earth theory that enables us to fly to the sun (or, say, 80% of the way to the sun) to do further tests?
