Several of us are going to Wolf Creek over Labor Day weekend. Any interest from members of this group? Great meeting last night by U of U professor on theories about dark matter and dark energy. "Normal" matter and energy are only 5 % of the mass of the universe. Dark matter is 25% and dark energy 70%. Dark matter can be explained by the concept of minimal acceleration, which may have been confirmed by the Pioneer spacecraft, now at the outskirts of the solar system. It appears to have a minute amount of additional acceleration that can not be accounted for otherwise. The amount is so small, however, that out-gassing from the spacecraft could have caused it. There are many esoteric theories including multidimensional space that may account for dark energy but so far no proof of any of them. -----Original Message----- From: utah-astronomy-bounces+djcolton=piol.com@mailman.xmission.com [mailto:utah-astronomy-bounces+djcolton=piol.com@mailman.xmission.com] On Behalf Of Michael Carnes Sent: Wednesday, August 24, 2005 7:00 AM To: Utah Utah Astronomy List Subject: [Utah-astronomy] Meeting last night I had a last-minute glitch and couldn't make it to the meeting. I really wanted to come, if only to prove I'm not dead yet. Anyone care to give a brief rundown?
