He will either tell you that he doesn't have to justify himself to you, or tell you to go read "earth not a globe".
He certainly will not ever post a source for that because he doesn't have one...because no such charts exist.
I don't see how his argument about swirling star clusters makes sense anyway. Consider the star Sirius, the brightest star in the sky, (there are many stars that would make my point but i'll just pick one). Sirius is visible from the northern hemisphere during the winter and can be observed moving around the north star. Sirius is also visible from the southern hemisphere during the fall and can be observed moving around the south celestial pole.
Tom claims not only two, but three swirling star formations; which begs the question: How could the same star (sirius in my example) be observed at roughly the same time to be moving in two (or apparently three) different swirling star formations?
