Opis

Two closely related subjects of high energy physics are introduce. The first one is clarifying in which physical state goes our hadronic world, when temperature and pressure extremely increased? The second subject is a very special case, in which we implement these experimental results on the physics of the Early Universe. In early universe, the matter is likely exotic hot and dense under assumptions of concrete cosmological principles. Nowadays technology allows reproducing these extreme circumstances in the laboratory, so that we can elaborate the physical characteristics experimentally. The recent heavy-ion collisions experiments proved that the matter is apparently relativistic fluid and possess non-vanishing viscosity. Our picture of Early Universe is basically based on the conjunction that the background matter is thermodynamically an ideal gas and/or just filled with radiation. Implementing shear and/or bulk viscosity and other transport properties into the standard cosmological model would give another picture about the dynamics of Early Universe and have essential consequences on the whole astrophysical evolution of our Universe.
