Just caught the movie "Time Machine" (the newest one) on a rental DVD. Apparently, in the movie, our descendants manage to blow the Moon to bits with a 20 megaton bomb used to excavate a lunar colony. Okay, it's only a movie, and a cheesy one at that, but does anyone think about this stuff at all? How many cumulative megatons do they think the Moon has absorbed to create the thousands of huge craters across its surface?

Again, it's only a movie, but this crap will come back to haunt us when someone, for example, proposes Orion-type vehicles for lunar applications, and some jackass pipes up that we'll blow up the Moon, like he saw somewhere.

Okay, it wasn't as downright stupid as "Space, 1999" where a nuclear waste dump blew up and threw the Moon--in one piece--into interstellar space.
