Just a side note, we were arguing at work whether if a black hole was created and if it swallowed the earth, would it swallow the moon, or even say the international space station. I was of the opinion that the mass of the black hole wouldn't be any greater than that of the earth, so it's grav force would be the same as the earth, and the moon and ISS would remain in orbit.
OK, I think
what's supposed to happen is that the black hole drops through the center of the Earth, eating stuff as it goes, bouncing back and forth, turning the Earth into Swiss cheese* in the process. Eventually it would settle down in the core and suck the rest of the planet down at its leisure. The mass of the thing would be the same as the Earth, but perhaps the process of collapse would be somewhat... er... energetic, which might... um... interfere with the orbits of the Moon and ISS.
OR, I could be blowing smoke out my ass.* How appropriate.
