Influence of Thermal Radiation on Singular Behavior of the Universe

Russian Physics Journal Aims and scope

Cosmological models with inhomogeneous viscous fluids and a logarithmic equation of state in the Friedman– Lemaitre–Robertson–Walker Universe are considered. The influence of thermal effects caused by Hawking radiation on the visible horizon of the Universe on the change in the singularity type of the dark Universe is investigated. It is shown that under the influence of thermal radiation, taking into account the viscosity property of a dark fluid, a qualitative change in the type of the Big Rip singularity is possible, which can lead to the absence of the singularity in the Universe at all.
