Scientists at CERN's ALICE detector have made a groundbreaking discovery, detecting the first evidence of the heaviest antimatter particle ever found, antihyperhelium-4. This particle is the partner of a massive matter particle called hyperhelium-4, and its discovery could help scientists understand the mystery of why regular matter dominates the universe. The Large Hadron Collider (LHC) generated a state of matter called "quark-gluon plasma" by colliding lead nuclei, allowing scientists to study the conditions of the early universe and potentially shed light on the universe's origins.
