OK. Thank tou for the debate regarding the existence of the north pole. I have actually been to the ise edge too when working on a research vessel.
However I still feel like I got little explanation regarding the midnight sun in the north and south.
However for those who has never experienced the shift of seasons in the north or south. It's not a sudden thing. The light fades more day by day almost unnoticeable until one day you realize the nights are light again
I searched here and found a few threads on the subject which revealed nothing. On the other site, in their wiki they have this:
"Path of the sun, the moon, and the stars
The Moon and Sun travel along the Aetheric Whirlpool. The Sun is relatively near a portion of the whirlpool comparable to an eyewall, which causes Sunset and Sunrise. It moves from side to side on this wall, which is the reason for the seasons. The stars are somewhere near the top of the whirlpool.
Sunset/sunrise and the Midnight Sun
The sunrise/set and midnight sun are caused by a several eyewalls throughout the Whirlpool, which distort light to the point that it does not reach the earth."Which again, reveals nothing.
Phew solves zero problems, it just rearranges the deck chairs on the Titanic.
So I think it's safe to assume that like many phenomena, to FE, the explanation is unknown.
