This substance may be composed of massive compact halo objects or weakly interacting massive particles.
The structure of some objects containing this substance was investigated by Navaroo, Frenk, and White using N-body simulations. Valentjin and van der Werf suggested that molecular hydrogen accounts for most of this substance. Douglas Clowe "proved" its existence while studying the Bullet Cluster and gravitational lensing effects. This substance may be composed of massive compact halo objects or weakly interacting massive particles. This mostly non- baryonic substance is divided into warm, hot and cold types. For 10 points, name this hypothetical substance that, along with dark energy, makes up around eighty-five percent of the mass of the universe.
