Quark wakes reveal early universe plasma flowed like a liquid
In its first instants, the universe formed a searing quark gluon plasma in which quarks and gluons moved at near light speed before cooling to build the protons and neutrons that dominate matter today. Physicists at CERNs Large Hadron Collider are recreating this primordial plasma by smashing together heavy ions at relativistic energies, briefly liberating quarks and gluons so they can pro
