Today's (7-24-2002) "Astronomy Picture of the Day" shows the position of the (known) asteroids and comets in the inner solar system. It's pretty cool!

Great! I've seen these before and I remember posting them here once, but I didn't save them as bookmarks back then. I've been wanting to find them again. I especially like the Trojan points of Jupiter.

Makes our solar system seem crowded doesn't it? But you have to remember that the scale is vastly exaggerated and there are really millions of kilometers between each of these points. If you do the solar system walk, you get a better idea of just how far apart these things really are. There really is very little out there, actually.

Aside: There is a thread at the Straight Dope BB what discusses quantum weirdness. The OP asked if there had been certain studies done concerning the double slit experiments. Specifically, he asked if anybody had set up the double slit experiment with detectors in the slit, but then no one observed or recorded the detector results. One of the moderators, a physicist, assured him that there would be no diffraction pattern, but there were other sources that seemed to say otherwise.

I'm thinking, if I go back and check that thread again, those answers may have changed.
