The southern sky breaks the flat-Earth map

The claim

“A flat Earth with a central North Pole explains the sky just as well as a globe.”

What is measured

South of the equator the stars circle a second celestial pole the opposite way, the noon Sun sits in the north, and observers right around the globe all see the same southern constellations due south. A flat disc with one central pole cannot produce any of this. A spinning sphere produces all of it.

What would show this is wrong

a single self-consistent flat-Earth star map that reproduces the south celestial pole, the clockwise southern rotation, and identical southern constellations seen due south from Australia, Chile and southern Africa simultaneously.

  1. Sigma Octantis, the south pole star. The southern sky rotates about the south celestial pole near the faint star Sigma Octantis (magnitude ~5.5); too dim for navigation, so the Southern Cros link
  2. The two celestial poles. Northern stars circle Polaris anticlockwise; southern stars circle the south celestial pole clockwise, and the same southern constellations are seen due south across link
