Why does the stars in the night sky in the North hemisphere rotate counter-clockwise around Polaris, while stars in the South hemisphere rotate clockwise? Shouldn’t the stars rotate in the same direction no matter were you are on the flat Earth?
Imagine you are standing (
near the equator middle on a mountain in Equador ) on a flat earth with the celestial sphere above, and this celestial sphere with the fixed stars is rotating if you look towards the north you will observe the stars rotating anticlockwise, now turn around and look south, you will observe the stars rotating clockwise.
Of course this is mechanically equivalent to the stars being a long way away and the earth rotating, and you'll need to create lots of extra rotating spheres for planets and comets. Look up Ptolemy for more details.
I'm in favour of the Copernican version. It's equivalent and simpler.
By the way, I'm not a flat earther. The earth is actually somewhat spherical.
