CERN Physicists Find Clearest Evidence Yet of Quark-Gluon Plasma Behaving as a True Liquid

Physicists at CERN's Large Hadron Collider, led by a team from MIT, have captured the clearest evidence to date that quark-gluon plasma—the scorching-hot matter that filled the early universe—behaves like a true liquid. By tracking individual quarks, researchers observed them creating ripples and wakes as they moved through the plasma, similar to a duck moving through water.
