Collider Study Recreates Early-Universe Plasma, Reveals Unexpected Shift in Matter Behavior
A new analysis of heavy-ion collisions at the Relativistic Heavy Ion Collider suggests scientists have recreated, in miniature, the searing primordial soup that filled the universe moments after the Big Bang. The results point to an unexpected decline in particle correlations in gold-ion collisions, offering a fresh clue about how matter organized itself as the cosmos cooled.
