Published on 16 Sep 2008 in: Science
Dark matter is matter that cannot be detected by electromagnetic radiation, hence dark.
Dark matter are divided into three different types (HDM, WDM, CDM) :
* Hot dark matter - nonbaryonic particles that move ultrarelativistically
* Warm dark matter - nonbaryonic particles that move relativistically
* Cold dark matter - nonbaryonic particles that move non-relativistically
