Danish scientists have created a model that shows how the quark-gluon plasma, which arose in the first moments after the Big Bang, behaved.
It is generally accepted that quark-gluon plasma was the first matter in the universe. A new study conducted by staff at the University of Copenhagen has shown the properties of primordial matter. It turns out, for example, that the plasma behaved more like a liquid than a gas when it existed in the first microseconds after the Big Bang.
“When the universe began to unfold from the singularity, a quark-gluon plasma, a substance of quarks, gluons, and antiquarks, emerged. The structure of such plasma is similar to that of ordinary plasma of electrons and ions, but the quark-gluon plasma shows more exotic properties, and is formed at much stronger energies,” say the authors of a new scientific paper.
Plasma, the properties of which the Danish researchers determined, existed in the first 0.000001 seconds of the universe, and then turned into hadrons. Scientists were able to obtain a model of primordial matter using the Large Hadron Collider. Experiments at the LHC showed what happened to the first matter, plus scientists created a special algorithm that can analyze the overall behavior of multiple particles during expansion.
