How is it possible that we are hurdling in circles around the sun through space going 67,000 mph, while spinning on our axis at 1,040 mph all while Polaris (The North Star) remains PERFECTLY aligned straight above the north pole throughout history?
From a Heliocentric perspective, Polaris, located directly above the north pole, should not be visible anywhere in the Southern Hemisphere. For Polaris to be seen from the Southern hemisphere on a spinning ball Earth, the observer would have to be somehow looking "through the globe" and miles of land and sea would have to be transparent. However, Polaris can in fact be seen up to over 20 degrees South latitude. How so, if the world is a globe?
If the Earth were a ball, the Southern Cross and other Southern constellations would all be visible at the same time from every longitude on the same latitude as is the case in the North with Polaris and its surrounding constellations.
Stigma Octantis is claimed to be a Southern central pole star similar to Polaris around which the Southern hemisphere stars all rotate around the opposite direction. Unlike Polaris, however, Sigma Octantis can NOT be seen simultaneously from every point along the same latitude, it is NOT central but allegedly 1 degree off-center, it is NOT motionless, and in fact cannot be seen at all using publicly available telescopes. What gives, Neil?
There is legitimate speculation regarding whether Sigma Octantis even exists. Either way, the direction in which stars move overhead is based on perspective and the exact direction you're facing, not which hemisphere you are in.
