Collider is cookin’, but is it soup?
By making the densest, hottest matter ever in a lab, smashups between fast-moving nuclei in the Relativistic Heavy Ion Collider are coming closer than ever to reproducing the superhot, primordial fluid that presumably filled the universe immediately after the Big Bang.
