CERN Recreates Microscopic Droplets of Primordial Quark-Gluon Plasma Using Oxygen Nuclei

Scientists at CERN have successfully recreated microscopic droplets of quark-gluon plasma, the near-perfect liquid that existed a millionth of a second after the Big Bang, by colliding oxygen nuclei. This extends the evidence of parton energy loss, or jet quenching, to the smallest nuclear system studied to date, providing new insights into the early universe.
