Slow-decaying heavy neutrino may explain why matter survived the Big Bang, researchers say

Researchers at the University of Southampton say a particle long written off as irrelevant, called a decoupled heavy neutrino, may have helped matter beat antimatter. Author Rishav Roshan says it decays so slowly that it briefly took over the early universe's energy. The team suggests checking this through gravitational waves from the early universe, and says it could also shed light on dark matter.
