  • It has been called a bruise on the sky--a curious cold spot in the afterglow of the big bang that has sparked wild cosmic theories attributing it to a run-in with another universe or a wrinkle in space-time. Now it seems the answer may be a little more mundane: the biggest known hole in the universe. The cold spot appears in maps of the cosmic microwave background (CMB), the earliest light emitted in the universe. Istvan Szapudi at the University of Hawaii in Honolulu and his colleagues analysed an all-sky survey made by NASA's WISE satellite to conduct their own hunt for a giant void. In May, they reported finding one about 2.8 billion light years away, in the direction of the cold spot.
