Heavy Neutrino Theory Offers a New Route to Matter’s Survival
Key Takeaways
- Researchers propose that a hypothetical decoupled heavy neutrino may have briefly dominated the early universe’s energy density.
- That temporary era could have affected conditions that enabled matter to outnumber antimatter.
- The particle’s proposed long lifetime is central to the mechanism.
- The model is theoretical and may be tested through predicted gravitational-wave signatures.
