94)” From the highland near Portsmouth Harbor in Hampshire, England looking across Spithead to the Isle of Wight, the entire base of the island, where water and land come together composes a perfectly straight line 22 statute miles long. According to the ball-Earth theory, the Isle of Wight should decline 80 feet from the center on each side to account for the necessary curvature. The cross-hairs of a good theodolite directed there, however, have repeatedly shown the land and water line to be perfectly level.”

Incomprehension of geometry.

Again, see #60. Geometrically, there is no reason for the horizon to be noticeably curved from these low altitudes.  A circle as viewed from the center (only with a tiny, tiny offset for your altitude) forms a LINE.

The horizon seems flat!


Yes, that's why we discussed the Applied Optics paper. See Point 60
