Liquid-State Transition of Quark-Gluon Plasma as the Origin of Atomic Nuclei and Matter Dominance

The hypothesis that the true identity of the quark-gluon plasma is a gas of quarks and gluons confined within a graviton film was proposed in a previous study. It was subsequently shown in another study that, at distances on the order of the Planck length, a real graviton acquires a mass on the order of the Planck mass owing to its self-energy. This nonperturbative quantum gravitational effect induces the formation of a film structure composed of real gravitons, a graviton film. As the system cools, the quark-gluon gas confined within the graviton film transitions to a liquid state. We demonstrate that this liquid state satisfies the three Sakharov conditions, implying that the existence of a graviton film inevitably leads to a matter-dominated universe in the course of cosmic evolution.
