Exact Solution to Model Big Bang, Quark Gluon Plasma Published

December 24, 2014 10:07 am | by Kent State University | News | Comments

Unlike in mathematics, it is rare to have exact solutions to physics problems. The first exact solution that describes a system expanding at relativistic velocities radially and longitudinally has been presented by researchers. It applies to a wide array of physics contexts and will help to better model galactic structure, supernova explosions and high-energy particle collisions, such as those studied at the Large Hadron Collider at CERN.
