Kinds of cold dark matter :

• weakly interacting massive particle (4 facts) (WIMP) - Some astronomers believe that these exotic subatomic particles make up most of the mass of the universe., A generic term for a class of hypothetical particle which may form the missing mass. A form of non-baryonic cold dark matter.
