Dark radiation
Dark radiation is a postulated type of radiation that is supposed to mediate interactions between particles of dark matter .
Similar to the particles of dark matter, dark radiation should not interact with baryonic matter. Although there is no direct evidence for this type of radiation, it is believed that it could be responsible for the accelerated expansion of space .
It is possible that the interaction particles are sterile neutrinos .
