Strongest evidence yet that neutrinos explain how the universe exists

New data throws more support behind the theory that neutrinos are the reason the universe is dominated by matter. The current laws of physics do not explain why matter persists over antimatter - why the universe is made of 'stuff'. Scientists believe equal amounts of matter and antimatter were created at the beginning of the universe, but this would mean they should have wiped each other out, annihilating the universe as it began. This result brings us closer than ever before to answering the fundamental question of why the matter in our universe exists. Dr Patrick Dunne Instead, physicists suggest there must be differences in the way matter and antimatter behave that explain why matter persisted and now dominates the universe. Each particle of matter has an antimatter equivalent, and neutrinos are no different, with an antimatter equivalent called antineutrinos. They should be exact opposites in their properties and behaviour, which is what makes them annihilate each other on contact.
