Don, you mentioned vacuum energy in one of your replies. This brings to mind an excellent book from a few years back called "The Hole in the Universe: How Scientists Peered Over the Edge of Emptiness and Found Everything", by K.C. Cole. It deals with the science of nothing--why a vacuum isn't and so on. Depending on your nature, it will either put you right to sleep or keep you from sleeping at all. -----Original Message----- From: Chuck Hards <chuckhards@yahoo.com> Sent: Aug 24, 2005 12:34 PM To: Utah Astronomy <utah-astronomy@mailman.xmission.com> Subject: RE: [Utah-astronomy] Wolf Creek and Meeting last night Thanks, Don. Although perhaps gravitational lensing techniques would have detected them also, I wonder about black holes in mass-poor regions- those with no accretion disks, and thus no emmisions (other than gravity waves). Or perhaps "small" black holes, those unrelated to stellar evolution? Surely we haven't inventoried all possible large forms of baryonic matter. --- "Don J. Colton" <djcolton@piol.com> wrote:
He didn't talk about elements with high atomic numbers.
He discussed brown dwarfs etc. as a possibility but said numerous surveys using gravitation lensing etc. had failed to convince anyone this was a significant component. He didn't talk about the other possibilities but we ran out of time for questions.
