The images of the Big Bang's afterglow, known as the cosmic microwave background, also delineate the cosmos' composition: 4 percent is ordinary matter; 23 percent is invisible stuff called cold dark matter, which prompted the galaxies to coalesce; and 73 percent is so-called dark energy, which has accelerated the rate at which the universe expands (SN: 5/25/02, p.
