n artistic conception of a heavy-ion collision producing quark-gluon plasma. Using TeraGrid resources, a group of scientists calculated key properties of quark-gluon plasma at a resolution previously unattainable. Immediately after the big bang, the early universe had no stars, planets and galaxies that we see today. Instead, it began as a hot plasma mixture of quarks and gluons that eventually cooled and condensed into the protons and neutrons that formed the heavenly bodies we're so familiar with. Physicists at CERN (the European Center for Nuclear Research) are conducting experiments involving collisions of heavy nuclei to temporarily recreate that primordial quark-gluon plasma and see how it may have cooled and condensed.
