Dark Matter
Hi everyone I'm new to this group. Is everyone or most everyone here
scientist and / or have ph.d's or degrees in this area? is this open for no degreed persons? I hold no credentials however am very curious about space, astronomy ect. I mostly read and watch informative shows i.e. nova ect. Question: anyone have any personal theorys on what the Dark Matter of space might be? I read in some article that with all the stars and suns in the universe it didnt make sense that the universe is dark. I have my own thoughts on this but first wanted to hear what other people are coming up with. |

You should take a look at it: http://en.wikipedia.org/wiki/Dark_matter "At present, the most common view is that dark matter is primarily non-baryonic, made of one or more elementary particles other than the usual electrons, protons, neutrons, and known neutrinos. The most commonly proposed particles are axions, sterile neutrinos, SIMPs (Strongly Interacting Massive Particles), and WIMPs (Weakly Interacting Massive Particles, including neutralinos)." I read in some article that with all the stars and suns in the universe it didnt make sense that the universe is dark. I believe you are confusing dark matter with Olbers' paradox, which is the observation that, if there were an infinite number of stars in infinite space, every point in the night sky would be illuminated. Olbers' paradox really has nothing to do with dark matter. The explaination for the paradox has to do with the expainsion of the universe (unknown in Olbers' time) and the finite age of the universe, and even so, it turns out that the universe is finite. hope that helps. chris |
