Densest Matter Created in Big-Bang Machine

Large Hadron Collider

A superhot substance recently made in the Large Hadron Collider (pictures) is the densest form of matter ever observed, scientists announced this week.

Known as a quark-gluon plasma, the primordial state of matter may be what the entire universe was like in the immediate aftermath of the big bang.

The exotic material is more than a hundred thousand times hotter than the inside of the sun and is denser than a neutron star, one of the densest known objects in the universe.
"Besides black holes, there's nothing denser than what we're creating,"
said David Evans, a physicist at the University of Birmingham in the U.K. and a team leader for the LHC's ALICE detector, which helped observe the quark-gluon plasma.
"If you had a cubic centimeter of this stuff, it would weigh 40 billion tons."
