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).
Lambda is the term that represents what we now also call dark energy - it's the same thing. CDM refers to cold dark matter. There is more confidence about the dark matter part than about the cold part. Some kind of dark matter is postulated because it explains a few otherwise anomalous observations. The most famous and first one of these is the rotation curves of galaxies.
