It doesn't matter how many times I produce that graphic

because it still shows the 26,0000 year precession of the poles, not an annual orbit of the sun. The fact that the North pole points at the North star throughout the year proves this.

I repeat,it doesn't matter how many times I show the graphic along with polar sunrise within the context of the polar day/night cycle, the surface rotation which causes the Sun to come into view for the first time in 6 months is a property of the Earth's orbital motion alone and the polar surface points offer a window into that surface rotation -

The issue is what is the dynamic behind the polar sunrise and 6 months later polar sunset at the same location. The answer is and always will be that as the Earth travels around the Sun those polar points turn parallel to the orbital plane and to the central Sun.

The larger matter is who can appreciate the beauty of a sunrise for what it is and especially that sunrise made possible by people down at the Antarctic latitude. There are no medals or honors for this no more than there is for appreciation of beautiful music, it only lets the person know that they are capable of goodness, dignity and have the intelligence to admire something greater than themselves.
