    Actually my good man Donno, you reiterated what I stated, but just used more words!

Here's a link to an article in Physics Today that discusses the formation of the Moon: http://www.geo.umass.edu/courses/geo...h-Wood2011.pdf

    They had a show on the Science Channel showing how it most likely formed with a collision of a rogue planet into the Earth. Made a lot of sense when this one scientist showed that since the moon slowly slips away from the Earth each year, she ran a computer program to reverse its path and demonstrated how long ago it would have hit and how large the impacting planet would have been.
    Very entertaining and educational.
