Physicists measured a new property of the hot, dense matter created when lead nuclei collide at near-light speed at the Large Hadron Collider, specifically how momentum fluctuations of particles correlate over long distances. The measurements, broken down by particle type, showed patterns consistent with the collective outward expansion (radial flow) of the matter, and revealed sensitivity to the matter's bulk viscosity. This new observable helps constrain fundamental properties of the quark-gluon plasma — the extreme state of matter that existed just after the Big Bang.
