Heavy Neutrino Theory Proposed to Explain Universe's Matter-Antimatter Imbalance

Researchers from the University of Southampton and the Indian Institute of Technology Kanpur have proposed a new theory involving a previously overlooked heavy neutrino. This particle could explain why matter survived the Big Bang, leading to the existence of stars, planets, and life. The theory suggests this neutrino reshaped the early universe and may have left detectable traces in ancient gravitational waves.
