A sextant measures angles on a plane and 1 minute = 1 mile; this can't be refuted.
Space is made up of an infinite number of planes, all of which are either parallel to each other, or at an infinite number and variety of angles to each other. This is precisely why a sextant is not accurate for measuring distance and sizes of very distant objects in space.
Where is the distance limit on FE? Does FE go on forever in every direction? Even if there is a dome, why wold space not go on forever in every direction, right on through the water above and outside of the dome, just like FE might go on forever past the point where the dome touches down on the ice/land outside the ice limit that GE people call Antarctica?
Or do you think that the flat earth is a simple plane, made up of an infinite number of points that have a length/width relationship to each other, but no height relationship to each other?
You seem to be missing a lot in your primitive calculations.
The Sun's diameter is 32' (arc minutes/nautical miles) and this is a direct measurement with no calculations involved. Only when the question of distance (from viewer to Sun) comes into play is trigonometry involved and, the margin of error in either case is not millions of miles for God's sake.
My proof stands and can't be refuted.
Well, of course you say this. Everything we see is seen in 2D. The reason we understand 3D is that we have two 2D cameras - eyes - and a brain that interprets the 3D reality.
The sextant, being a 2D measuring system, has to be used to make many 2D "pictures" that we combine to form a 3D view of reality. The sextant is not made to interpret 3D from the one-at-a-time 2D pictures that it makes. When used this way, even the sextant shows us that its measurements are not accurate beyond a certain distance. That distance is understood by the relationship of, say, the number of distant stars we can observe with a single, optic nerve unit. This is why we have telescopes.
But you can't make the rest of a sextant (even one that has a telescope) to be more accurate, without greatly expanding its size. Standard big telescopes, mounted in domes so that they can be protected at the same time they are being adjusted, essentially act like giant sextants. They prove that the sky and sun are far bigger and farther away than the limited, hand-held sextant suggests. The difference is that the big telescopes simply aren't called sextants any longer... often because they have many additional items incorporated into them that sextants don't have.
