Proposed elusive subatomic particles that only fleetingly interact with matter through gravity may not exist, at least if new data from a nuclear reactor is any indication. Scientists had long noticed a discrepancy between the predicted and actual number of antineutrinos, or the antimatter partners to neutrinos, produced in nuclear reactors. Now, a new analysis suggests that this reactor antineutrino discrepancy isn’t the result of a new hypothetical particle known as a sterile neutrino. Instead, the theoretical models may have been wrong all along, data from the Daya Bay nuclear plant in China suggests…
