Physicists see quarks make waves in the Big Bang's primordial soup

Physicists at CERN's Large Hadron Collider have captured the clearest evidence yet that quark-gluon plasma, the hot matter of the newborn universe, behaves like a true liquid. Tracking individual quarks through the plasma, researchers saw ripples, splashes and swirling wakes resembling a duck moving through water.

• Quark-gluon plasma behaves like a liquid, not a gas
• Individual quarks leave ripples and swirling wakes in the plasma
• The plasma is dense enough to slow speeding quarks
• Data comes from CERN's Large Hadron Collider
