Physics: Quarks and Gluons explained

Physics: Quarks and Gluons explained Professor Claudia Ratti from the Physics Department at the University of Houston explains the essential information about quarks and gluons, including the so-called Quark-Gluon Plasma, plus Quantum Chromodynamics. Just a few microseconds after the Big Bang, a phase transition occurred in our Universe, during which a system of quarks and gluons (the so-called Quark-Gluon Plasma or QGP), by expanding and cooling down, transitioned into a phase of quark and gluon bound states (the so-called hadrons) that populate the Universe today. This phase transition happened at temperatures that are about a hundred thousand times hotter than the one inside the core of the sun and is driven by the strong force that binds quarks and gluons together.
