Actually Hara Taiki has made a VERY relevant point.
It is on this point alone that the entire flat earth theory
must crumble... It's dead easy to demonstrate too,
You just need to live in the Southern hemisphere, or
near the equator to verify this.
I will post a detailed explanation of this tomorrow after
Ive done some research on whats been said about this
here so far.
Note: I've left out the Northern hemisphere intentionally,
since Im sure FEers already have an explanation for this
effect above the North Celestial Pole.
