The world's most massive science experiment has done it again, detecting hints of the heaviest antimatter particle ever found.
This means the Large Hadron Collider (LHC), the most powerful particle accelerator ever built, has given scientists a glimpse into conditions that existed when the universe was less than a second old. The antimatter particle is the partner of a massive matter particle called hyperhelium-4, and its discovery could help scientists tackle the mystery of why regular matter came to dominate the universe, despite the fact that matter and antimatter were created in equal amounts at the dawn of time.
