Hot, Warm and Cold Dark Matters (HDM, WDM, CDM)

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
