Not Quite Omnipresent, Dark Matter is 96% of the Universe

"Everything humans observe in the heavens—galaxies, stars, planets and the rest—makes up only 4 percent of the universe, scientists say. The remaining 96 percent is composed of dark matter and its even more mysterious sibling, dark energy. Scientists recently found direct evidence that dark matter exists by studying a distant galaxy cluster and observing different types of motion in luminous versus dark matter. Still, no one knows what dark matter is made of. Now, a pioneering international project co-led by Stanford physicist Blas Cabrera may finally crack the case and pin down the elusive particles that form dark matter."

At U.C. Berkeley, the CDMSII: Cryogenic Dark Matter Search is "using state-of-the-art cryogenic germanium and silicon detectors, the CDMSII collaboration is searching for weakly-interacting massive particles, or WIMPS, whose discovery could resolve the dark matter problem, revolutionizing particle physics and cosmology."
