Simulations show swirling rings, whirlpool-like structure in subatomic 'soup'

At its start, the universe was a superhot melting pot that very briefly served up a particle soup resembling a "perfect," frictionless fluid. Scientists have recreated this "soup," known as quark-gluon plasma, in high-energy ...
