https://wiki.tfes.org/The_Full_Moon_is_Impossible_in_Round_Earth_TheoryThe logic in that page is flawed. It asserts that anytime the Moon is in a full Moon position, the light coming to it will be blocked by the Earth. That would be the circumstances for a lunar eclipse, and any astronomer on the Internet will happily explain to you
why that doesn't happen every month.
Since I am
also an astronomer on the Internet, I will explain it too. Since the article I'm battling says that I can't refute it no matter how much mental gymnastics I do with scale, I'll spite it by doing mental gymnastics with scale. I'll be using
this table from NASA as a reference.
The Moon's orbit is angled about 5° from Earth's orbit around the Sun. At its closest approach, the Moon is about 28 Earth-widths from Earth. At tan(5°)*28 I get 2 1/2 Earth-widths from the center maximum. The eclipse zone, for comparison, is one Earth-width wide.
Furthermore, the components of the Moon's path are sinusoidal, so the centerline where the eclipse zone is happens to be the line that the path crosses the fastest. Even though the eclipse zone is 20% of the possible heights, it spends only 13% of its time in the right latitude.
Please ask an astronomer about this before jumping to conclusions.
