When the universe first formed, it was too hot and dense for atoms to exist, filled instead with quarks and gluons in a quark-gluon plasma. As the universe expanded and cooled, these particles combined to form protons and neutrons, marking a significant phase transition. Recently, scientists at Brookhaven National Laboratory recreated this early universe state by colliding gold ions at high speeds, revealing new insights into this transition. The STAR experiment detected a surprising dip in momentum fluctuations, suggesting a possible phase transition at high densities. This discovery could help scientists understand the universe’s evolution and the behavior of matter in extreme conditions, like those in neutron stars.
