240 million light years from Earth? NASA astonomers clearly very much want to believe so:
NASA notes that normal matter may also have created the emission line, which appeared in the Perseus galaxy cluster, but astronomers are excited at the prospect that the sterile neutrinos may be at play. The scientists’ next step will be combining the data with results from other missions to see if the same X-ray signal appears in other galaxy clusters. Thus far, the line has also been found in 73 other galaxy clusters using NASA’s XMM-Newton.
“We know that the dark matter explanation is a long shot, but the pay-off would be huge if we’re right,” Esra Bulbul, leader of the study and a fellow at the Harvard-Smithsonian Center for Astrophysics, told NASA. “We’re going to keep testing this interpretation and see where it takes us.”
Based on the cosmic dust dust-up from BICEP (= not a multiverse, just signals from some dust), we’d recommend caution for now.
