    Is dark matter thought to be particulate? I thought it wasn't for some reason but reading about WIMPs suggests it is.

    A hypothetical form of matter whose influence we observe due to gravity.It's theorized to account for the unusual,constant radial velocity of galaxies (elliptical ones) which are significantly higher than our expected values in a region beyond the visible galactic disc.
    They're broken down into WIMPS and MACHOS(many disregard these since there isn't enough baryonic matter to consider the 23% of matter,least viable).
