First, that stuff about the "Fall of the Moon" in the newest movie version was
never imagined by H.G. Wells. In the book, civilization decayed in a gradual
way over the 800,000 years period.

Second, although I liked the movie (and the rest of the group will probably
burn me at the stake because of that :-), it is as scientifically sound as a
Superfriends cartoon. The energies required to move the Moon are so big that
we would probably need a Dyson sphere or systematic cometary bombardment to
do that - over a timespan of centuries. Nuking the Moon (like in the movie),
even with all our nuke stockpile, would do nothing except create an
unimpressive additional crater. (As a comparison, the impacts that created
the larger craters and presumably some of the Maria were zillions of times
intenser and the Moon kept its orbit.)
