Are you suggesting that a large rock, hit the earth, with blasted another rock into space, and then it was pelted by asteroids and became round? Then why doesn't it rotate on its axis? The moon rotates on its axis approximately once per month. |

Next you'll be claiming that you have to slow down to move from a high geostationary orbit to a lower geostationary orbit. Sheesh. A couple of years ago a guy actually argued something like that with me. He reasoned: The tangent speed of an orbiting satellite becomes smaller with increasing altitude. Thus, by bleeding off speed, the satellite will be induced to spontaneously rise! But this thing about the Moon's rotation is interesting. So many people come to the same misconception, that it doesn't rotate, because it always shows the same face toward Earth. They're not looking at the whole picture. If they were to ask what face the Moon shows to the other planets, and the distant stars, and the near star, our Sun... The fact that the Moon undergoes phases is itself a demonstration of its rotation. -Mark Martin |

hey, the moon has craters to seclude, every animal from every other animal.

In article , says... how about the Moon as Noah's Arch? -suresh Well it ain't no Von Neuman Probe. It is much too big to be a nanobot. It's also not hollow. Keep in mind that more than zero is known already about the Moon's innards. Orbital periods of satellites yield the Moon's mass, and therefore its mass density. A network of seismic detectors yields data as to the Moon's interior. It's not hollow. And what is that geometric regularity on the floor of crater Tycho? Well, let's ask this: What is that geometric regularity in the shape of crater Barringer, the one over in Arizona? Barringer's rim has a strong squareness to it. Does this mean that Barringer is an artifact, a construction project leftover from an ancient civilisation? No. The predominant bedrock in that region has a strong geometric regularity to it. There's square already there, in the rock. There's geology going on here. And the Moon, does it have geology? Yep. -Mark Martin |

news:1YoSb.330011$JQ1.286938@pd7tw1no... Well it ain't no Von Neuman Probe. I've sometimes wondered how we would react, or what we could possibly do, if a Von Neuman Probe came along and began converting our moon into a bunch more Von Neuman Probes. Seems like there ought to be a SF story in there. -- Regards, Mike Combs ---------------------------------------------------------------------- We should ask, critically and with appeal to the numbers, whether the best site for a growing advancing industrial society is Earth, the Moon, Mars, some other planet, or somewhere else entirely. Surprisingly, the answer will be inescapable - the best site is "somewhere else entirely." Gerard O'Neill - "The High Frontier" |
