I'm still not understanding his question.
He said "vertical shadow". That image shows that half the moon is in shadow because the sun is on the other side of it. We're talking about eclipses
Vertical means up and down, or perpendicular to a horizontal plane. The Earth casts a curved shadow on the moon during a lunar eclipse, which is one of the most damning pieces of evidence for a globe Earth:
They have absolutely no explanation for why there is a curved shadow during lunar eclipses, which is why ol boy had to exclude them from the conversation earlier:
The Eclipses:
This should be self-explanatory.
Solar eclipse: The moon passes in front of the sun
Lunar eclipse: That's a completely different discussion that should be set aside for now
This man believes the sun and the moon revolve above the Earth, meaning there are two objects up there. His explanation for Solar eclipses is that the moon goes in front of the sun. He is correct there-- the moon passes in front of the sun in reality.
The problem is that he doesn't use this same logic for the lunar eclipse, because it is impossible on his flat earth model. He doesn't have an explanation for why there is a shadow on the moon during lunar eclipses, because he cannot admit Earth is the thing causing that shadow.
Why does the moon randomly go in front of the sun? He has no explanation for that either.
How can the moon (which he thinks is a projection) block out the sun during a solar eclipse if the moon is a projection? He has no explanation for that either.
The only thing he can do is endlessly question reality, because he cannot explain his fake reality.
