"... You are ignoring the point. The point is that the sun appears smaller from further away, not larger or the same. But the amount is far less than it would be if the dome were only the approximately 18,000 3,000 [FTFY] miles high at the center that you seem to think. ..."
No I'm not ignoring the point, I clearly defined the difference between apparent visual size and angular size in post
#14537.
You entirely misuse angular size by neglecting angular shape. If angular size were applied as you said, angular shape would be that of a cat's eye slit.
"... Actually, so much for your claim. If you get atmospheric conditions just right, you can't see the sun at all... like at night. ..."
Day and night are not the result of atmospheric conditions.
But being able to see the sun often is. So, if you are going to make a claim, claim the whole thing. Not just part of your claim. Otherwise nobody will know what you are talking about, and they will try to explain what you said in different ways than you meant.
"... Star measurements are made from the center of the star, even if you can't lock in on it. If measuring off stars is assumptions, Sagnac, Michelson Morley, and Airy are assumptions, and flat earth fails because you have been placing your trust in them, even though you are backwards. ..."
1. You're completely ignoring refraction, the optical displacement caused is far too great by many orders of magnitude to be corrected by any minor adjustments.
2. None of the established experiments you listed made any assumptions and two of them don't even involve star light.
All I am using is refraction. FE perspective involves using refraction in non-standard ways. So, to answer anything you say, I have to assume FE angular refraction in everything. You can't simply jump backward and forward, into an out of, standard perspective and FE perspective and make any sense. Use one or the other.
Sagnac, Michelson Morley, and Airy automatically based all their experiments on their understanding of far distant star systems. They don't have to talk about it in their experiments to apply it automatically, right along with all the things of their experiments. Separating their experiments from the base of the star system knowledge they held, is like jumping back and forth between standard science and your understanding of FE science.
You are inventing a whole new skewed way of doing math, where "equal" only equals "equal" when you say it does, but not when you say it doesn't. The universe only works like that in the funny farm. Just ask your next door resident, Napoleon.
