Samuel Rowbotham originally estimated the sun was 700 miles up. We do not know how high up it is. Do not use the FAQ as evidence you are correct because the FAQ is not 100% correct.
It does not matter how high the sun is, the same problem would still be there. The south will always receive darkness, while we know from real world observations, the south also experiences 24h daylight, something impossible to achieve on a flat disc. At least I have not found the answer.
Furthermore it seems for most of the FET, the theory does not have a single answer as how it all should work. One says the sun is hoovering, the other says it is rotating, one says it is a flat disc, the other says it is a sphere. I have shown you the problem with a rotating sun around a flat disc, I have shown you a problem with a hoovering sun above a disc. These fundamental errors are not explained by anyone here, while when I look at my spherical earth, all the problems I addressed do no longer exist. It matches real world observations, so how do you still stand up with the FE theory?
I will wait for the explanation of the aetheric eyewalls, see if that brings any answers.
