Dark Matter Universe on the Threshold of Discovery
Ninety-five percent of the universe is missing! Astronomical observations suggest that most of the mass of the universe is in a mysterious form known as dark matter and most of the energy in the universe is in an even more mysterious form called dark energy.
While the nature of dark energy seems elusive, physicists are on the verge of confirming or refuting the leading dark-matter hypothesis that dark matter is a new elementary particle species known as a weakly-interacting massive particle, or WIMP.
Edward Kolb is is the Arthur Holly Compton Distinguished Service Professor of Astronomy & Astrophysics and the College and Chair of the Department of Astronomy and Astrophysics at the University of Chicago.
