Now if only those calculations could produce consistent results from different latitudes.
Which of your RET studies shows such results?
A lab experiment that I performed in 9th grade earth science class.
The problem is that even "the Wiki" gives
reasonably accurate angles for the sun elevation at any latitude.
These angles prove that the 5,000 km calculated sun height is obtained
only for the equator and the 45° latitude distances.
Using other spacings puts the Flat Earth sun at anywhere from 6,408 km (for 1° latitude) to 0 km (for 90° latitude). Why does TFES chose 45° latitude?
But it is very significant that "the Wiki" values for the sun elevation
give completely consistent results for a Globe earth and a distant sun (actually at
infinity no "the Wiki" is not perfect
)
In other words "the Wiki" of TFES proves that the earth is a Globe earth with a distant sun.
