Scientists throughout the world have been trying to unlock the mystery of dark matter for decades, but we still don’t know what the mysterious object is. Now, a team of scientists has evaluated a popular dark matter theory. The team found no evidence that so-called sterile neutrinos are the key to understanding dark matter. Researchers tried to find supporting proof for the sterile neutrino in 20 years of historical data from the XMM-Newton space X-ray telescope. Scientists believe the outcomes don’t necessarily mean sterile neutrinos aren’t a key source of dark matter. However, it does suggest that the lack of evidence for this theory doesn’t stand up to investigation.
