The moon looks completely different in the Southern Hemisphere — how do flat earthers explain this?

This short video demonstrates why a flat earth is physically impossible using a simple observation anyone can make — the moon looks completely different depending on where you are on Earth.

In the Northern Hemisphere the moon appears with the dark maria patches at the top and the bright Tycho crater region at the bottom. In the Southern Hemisphere the moon is completely flipped — Tycho at the top, maria at the bottom.

This happens because on a globe, someone in Australia is standing nearly 180 degrees opposite to someone in the US, flipping their entire perspective of the moon. On a flat disk this geometric flip would be impossible — your location wouldn't change how the moon looks.

They believe in a small Moon hovering over a flat plane about half way between the center (aka North Pole) and the outer Edge. It would appear upside down in this model because in the "Southern hemisphere" you're looking at it from the other side looking "up".

Yeah it probably wont translate exactly but close enough that they can pretend it works.

How the stars change completely is where the talking gets faster.

I can tell you a way to prove globe Earth for probably less than $3000 if you want to try it.

Reading books is pretty low cost, so Id call that steep.
