Dark matter. Written By: Dark matter, a component of the universe whose presence is discerned from its gravitational attraction rather than its luminosity. Dark matter makes up 26.5 percent of the matter-energy composition of the universe; the rest is dark energy (73 percent) and âordinaryâ visible matter (0.5 percent).
WIMPs as dark matter. Although the existence of WIMP in nature is hypothetical at this point, it would resolve a number of astrophysical and cosmological problems related to dark matter. There is near consensus today among astronomers that most of the mass in the Universe is dark.
