This is a very good survey of new cosmological thinking.
I have been very suspicious of the anthropic principle for a long time; I have mostly rejected it. The finely-tuned universe has been equally suspect, to me. Now I have hope that these ideas are unnecessary. Any number of other universes probably are most probably not properly tuned to support life as we know it. I also find that the "final goal" of science to be possibly illusory to be quite amusing and satisfying.

Asteroid data reduction

The photo above was taken on 11/2/08. The target object was Comet 44P. I took two sets of 10 2 minute exposures about 36 minutes apart. The initial processing (alignment, stacking) was done using AstroArt 4.0. The initial astrometry was done using AstroArt against 5 UCAC2 stars. The final astrometry was done using Astrometrica against several thousand USNO B.0 stars. Astrometrica can also overlay the calculated positions of all known asteroids and comets in the field of view. 44P is in the middle of the field almost exactly as plotted. I found 7 others. Could be more.
Left of 58416 there are two list so that you cannot read either; they are in the photo. 43620, 08184 and 30967 were found. Two were found near 08107.
