The supersymmetric neutralino is one candidate for this substance, which is believed to be a weakly interacting massive particle, or WIMP.
N-body simulations overestimate the central distribution of this substance, resulting in the cuspy halo problem. The supersymmetric neutralino is one candidate for this substance, which is believed to be a weakly interacting massive particle, or WIMP. Fritz Zwicky postulated this substance after observing the Coma cluster, and its existence can explain why galaxy rotation curves don't drop off as they should. For 10 points, name this substance that makes up about a quarter of the content of the universe but is not detectable by electromagnetic radiation.
