Heavy ions and quark-gluon plasma
CERN physicists collide heavy ions to free quarks - recreating conditions that existed in the universe just after the big bang
ALICE
ALICE detects quark-gluon plasma, a state of matter thought to have formed just after the big bang

The big bang should have created equal amounts of matter and antimatter. So why is there far more matter than antimatter in the universe?
The early universe
All matter in the universe was formed in one explosive event 13.7 billion years ago – the big bang
