6 days ago · dark matter, a component of the universe whose presence is discerned from its gravitational attraction rather than its luminosity. Dark matter makes up 30.1 percent of the matter -energy composition of the universe; the rest is dark energy (69.4 percent) and “ordinary” visible matter (0.5 percent). Originally known as the “missing mass ...
