WebOrdinary matter — aka baryonic matter — interacts via the electromagnetic, gravitational, weak and strong nuclear forces. These forces transfer energy and provide the structure of all matter. Dark matter, on the other hand, is usually viewed as an amorphous cloud of "stuff" that cannot interact via the electromagnetic, weak or strong forces. WebDark matter is one of the greatest unsolved mysteries in cosmology at the present time. About 80% of the Universe's gravitating matter is nonluminous, and its nature and distribution are for the most part unknown.
