teravore Posted July 11, 2006 Report Share Posted July 11, 2006 hey everybodyI was just wondering what the most up to date theories were concerning "dark matter" - what it is (eg. non-baryonic matter or whatever) and how it interacts with the normal matter of the universe. Also of interest is how dark matter could be harnessed or cause problems. Cheers for your input Quote Link to comment Share on other sites More sharing options...
Jay-qu Posted July 11, 2006 Report Share Posted July 11, 2006 give this site a quick search there have been a few threads about it in the past :esmoking: Quote Link to comment Share on other sites More sharing options...
UncleAl Posted July 11, 2006 Report Share Posted July 11, 2006 http://www.edge.org/3rd_culture/krauss06/krauss06.2_index.html Uncle Al votes for "dark matter" being the difference between Newtonian gravitation and an exact solution to General Relativity being applied to galactic rotation. Dark matter is composed of laziness. Quote Link to comment Share on other sites More sharing options...
Coronus Posted July 11, 2006 Report Share Posted July 11, 2006 The two predominent candidates for dark matter are MACHOs and WIMPs I'm up for WIMPs cuz well they sound cooler..... Quote Link to comment Share on other sites More sharing options...
Jay-qu Posted July 12, 2006 Report Share Posted July 12, 2006 I think they will both contribute some mass but more likely more mass comes from MACHO's just because in the galactic halo there are a lot of old dead stars that are not easily visible.

Coronus Posted July 12, 2006 Report Share Posted July 12, 2006 Yer but the raw idea of a WIMP seems some what mystical in a sense...I mean just fact that we know next to nothing about them openes them up to massive speculation..But yer it's proberbly a mux of the two...

Jim Colyer Posted July 13, 2006 Report Share Posted July 13, 2006 I am baffled by dark matter. Quote Link to comment Share on other sites More sharing options...
Coronus Posted July 13, 2006 Report Share Posted July 13, 2006 I am baffled by dark matter. I suppose you'd have to be even more baffeled were you faced with alternative.I mean this supposed dark matter does explain a lot of how the galaxies and clusters formed.
