Scientists reveal the hidden force driving the universe’s hottest fluid
Physicists have mapped the acceleration of quark-gluon plasma, an exotic state of matter created in high-energy particle collisions. The study reveals that the edges of the plasma fireball act as acceleration hotspots, providing new insights into the thermodynamic properties of matter shortly after the Big Bang.
When atomic nuclei crash into one another at nearly the speed of light, they briefly produce quark-gluon plasma, an extraordinarily hot state of matter in which quarks and gluons can move freely. This exotic material behaves like an almost perfect fluid and offers scientists a way to study conditions similar to those that existed shortly after the Big Bang.
