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).
A black hole is a region of spacetime exhibiting such strong gravitational effects that nothingâincluding particles and electromagnetic radiation such as lightâcan escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
