It has possibly created at the (*) Brookhaven Relativistic Heavy Ion Collider, but results suggest the substance created there does not exhibit the material behavior its name implies, but rather more as a liquid.  Below the energy necessary to form it, the components of this substance undergo hadronization and are bound in normal matter.  Believed to be the state of the universe at an age of a few microseconds, for 10 points, name this state of matter in which certain elementary particles are deconfined.
