-
- Ummm..... if you listen to Pink Floyd's album, at the very end, they say
- "There really is no dark side of the moon." They say this because whether
- the moon faces the earth or not has nothing to do with the dark side.
- What is a new moon?

-
- The rotational velocity of the moon HAS changed, because the moon causes
- tidal motion which sucks energy out of its orbit. That is WHY the moon
- faces the earth. The only way the moon could change its rotational velocity
- to begin an uncoupled rotation would be an act of god, or else someone
- giving it some extra energy. It would not happen on its own.

-
- I'll agree with this. Anything on the moon's surface would be long
- buried after a few million years.
