He discussed in some detail all the known particles and eliminated each one in turn. There was some discussion about a particle that emits no energy and is stable. Apparently they are going to try to interact with such a particle, if it exists, using the one of the supercolliders. It would show up by being created from other particles and removing energy from a closed system. He also discussed how the energy of a vacuum state could account for a very small amount of the dark energy. Apparently there is no state (according to quantum mechanics) without at least some energy. -----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 Chuck Hards Sent: Wednesday, August 24, 2005 10:02 AM To: Utah Astronomy Subject: RE: [Utah-astronomy] Wolf Creek and Meeting last night Don, I last read a physics text in 1979 at the U, so please excuse me if I'm horribly out of date here, but what about WIMPs or other proposed massive particles? Any research progress there? I had read once, years ago, of speculation that there may be elements with atomic numbers above 200-300 that have remained undiscovered due to non-interaction with elements of lower atomic weight. Also, isn't it even remotely possible that the amount of 'normal' baryonic matter has been grossly underestimated? "Dark baryonic matter"- undetected dust and non-interactive gas, maybe? Or BM beyond the observable limits of the universe? Naive questions from a layman, thanks. --- "Don J. Colton" <djcolton@piol.com> wrote:
There are many esoteric theories including multidimensional space that may account for dark energy but so far no proof of any of them.
