- Scientists may have solved the mystery of why matter triumphed over antimatter after the Big Bang, allowing the universe and life to exist.
- A new study published in Physical Review Letters highlights a neglected particle known as a decoupled heavy neutrino as the key factor.
- Dr Rishav Roshan from the University of Southampton explained that the particle decayed extremely slowly, temporarily dominating the energy density of the cooling cosmos.
- The particle altered temperatures in the early universe, creating a crucial shift that enabled matter to survive rather than be annihilated by antimatter.
- Researchers believe these findings could also help unravel the mystery of dark matter and be verified by studying gravitational waves from the early universe.
