Nonbaryonic dark matter

Nonbaryonic dark matter refers to substances containing no atoms and does not interact with electromagnetic forces, such as black holes, axions, and supersymmetric particles. Dark matter is hypothetical in itself, not to mention the nonbaryonic form. As dark matter has no true shape or being, it is easily imaginable without atoms. This form of dark matter has extremely high or low mass, contributing to the dissimilarities in galaxy rotation curves. There are three promininent theories on nonbaryonic dark matter, which are Hot Dark Matter (HDM), Warm Dark Matter (WDM), and Cold Dark Matter (CDM), where WDM is a merger between the other two theories.This sort of dark matter normally deals with hypothetical calculations about what happens in a black hole, around a black hole, and forming a black hole. Although there are still many skeptics, nonbaryonic dark matter is generally accepted as existing, even in our own galaxy.
