Researchers at JQI and their colleagues have proposed a novel method for finding dark matter, the cosmos’s mystery material that has eluded detection for decades. Dark matter makes up about 27% of the universe; ordinary matter, such as the stuff that builds stars and planets, accounts for just 5% of the cosmos. (A mysterious entity called dark energy, accounts for the other 68%.)
There’s a big unsolved mystery in physics: The cosmic balance sheet for matter in our universe just doesn’t add up. Galaxies all over space move as though they are much heavier than they appear. Scientists postulate that they are full of stuff we cannot see, stuff that they call dark matter.
