Does nonbaryonic dark matter exist?

  1. Jun 13, 2003 #1
    People have "invented" it out of a need to explain large scale motions in the Universe, but is it really there? Might there be other explainations?

    Here's an interesting page about it.


    You can get more by putting "dark matter" into Google or MSN. Does what you know about it convince you that all the possibilites have been explored?

    Neutrinos have already been detected. As for how much nonbaryonic dark matter exists, I haven't a clue.
