Physicists Reveal the Big Bang’s “Primordial Soup” Really Flowed Like a Liquid

Scientists studying particle collisions at CERN have captured new evidence of how quarks move through the early universe’s primordial plasma. In the first instants after the Big Bang, the universe was not filled with atoms, stars, or even protons. It was a searing, trillion-degree mix of quarks and gluons moving at nearly the speed of [...]
