If these tiny particles have mass and are numerous, they could make up a ...Two varieties of dark matter have been found to exist. The first variety is about 4.5 percent of the universe and made of the familiar baryons (i.e., protons, neutrons, and atomic nuclei), which also make up the luminous stars and galaxies. The dark matter comprising the other 26.1 percent is in an unfamiliar, nonbaryonic form that is ...Dark matter appears to be a form of matter made up of an entirely different class or classes of subatomic particle.
