Hello.

I'm new to this forum and – let's be honest – have quite strong a certainty concerning the spherical shape of the earth. If that is a problem, we can avoid wasting everyone's time if the admin tells me so at the first moment possible, in which case this will be my first and last post.

And my actual question is here: what is the distance between the sun and the earth, assuming the flat earth? I really have tried to find this information on various sources but haven't so far succeeded. Also I'm not aware whether or not that distance is supposed to be constant or not. Some ancient flat earth cultures apparently believed that the sun went around the earth so that during the night it went below it, and that the thing supporting earth from below – whatever that was – allowed it to do so. However, it seems like this isn't the case with the modern flat earth theories.

In the globe theory it is widely accepted that the distance is about 150,000,000 km – or on average slightly less, but this is a good enough approximation, and twice a year it is exactly correct anyway. I learned this while in kindergarten. If the flat earth theory were true, wouldn't such fundamental things so important for understanding our universe be taught to children then, as well? And still, this information is so hard to find.

I made a diagram showing two different ways to calculate the distance (

*a*). What we need is two points on the surface of the earth, one exactly below the sun that obviously needs to be in tropic (P

_{1}) and one somewhere far enough (P

_{2}), and we need to know the distance between them (

*b*). We then need to measure the apparent height and the size of the sun in P

_{2} (

*α* and

*β*_{2} respectively) and the apparent size in P

_{1} (

*β*_{1}). The height in the latter is obviously 90°, but this can be measured anyway in order to be sure that we have the right spot. These measurements need to be made at the same time, which means that at least two persons are needed to make them.

If there is something wrong with the mathematic part, I'd be glad to know.

I don't ask you to actually make these calculations. If the flat earth theory were true, I'd assume they have already been made several times, and the results published. The problem is: I don't find the results.
