Hey Everyone! I've posted this question on both the physics and math sites, but I'm hoping that by fishing in all three that I might get an answer sooner! With that in mind... I'm trying to figure out how to calculate the resultant polar coordinates of a triangle following the triangle's...

I have a question about the rotation of the moon. Does the moon acually spin like the earth or does it just stand still, forever illuminating the sky with the same side that we see every night?

Which planet spins backwards?

This has been touched on in a few threads from time to time. I am interested to hear some different point of views on this. If we were to discover intelligent Life on another planet, how would that effect religious beliefs? Does it help to prove or disprove certain religions?

If the solar nebula theory is the correct explanation of how the solar system formed, then what is the likely cause of two planets being highly tilted or rotating “backwards,” and one planet not revolving in the same plane as the rest by more than 10 degrees?
