Physicists catch quarks making waves in the big bang’s primordial soup

So, physicists at CERN have found clear evidence that fast-moving quarks leave wakes in quark-gluon plasma, the ultra-hot matter that filled the young universe. By recreating this primordial soup in heavy-ion collisions at the Large Hadron Collider, the team saw signs that it responds like a unified fluid, with ripples and swirling motion. It’s a fascinating clue that this matter was dense enough to slow quarks down, rather than letting them scatter independently. Studying these wakes could reveal more about the plasma’s properties and the universe’s first few moments.
