The liquid after the Big Bang

In an experiment to collide lead nuclei at the Large Hadron Collider (LHC) at CERN, a team of British physicists has discovered that the early universe was not only extremely hot and dense, but also had a liquid consistency.

Using the ALICE detector, David Evans, University of Birmingham, and his team recreated the conditions immediately after the Big Bang, subatomic fireballs generated at temperatures above 10 billion degrees Celsius. Thus, Evans and colleagues have noted that under these conditions the universe behaved like a super-hot liquid. Furthermore, their studies show that when this "primordial soup" cools arising from fireballs thousands of different particles, many more than the models predicted theoretical physicists. "While still early, we are learning a lot about the early universe," admits Evans.
