The New Scenario of the Initial Evolution of the Universe

TL;DR

This paper explores the early universe's evolution from a quantum tunneling perspective, analyzing cosmological solutions, phase transitions, and cyclic models to explain the formation of observable particles.

Contribution

It introduces a model combining quantum tunneling, phase transitions, and cyclic cosmology to explain the universe's initial conditions and particle formation.

Findings

Quantum tunneling connects cosmological solution branches.

Relativistic phase transition influences universe evolution.

Multiple cycles lead to observable particle formation.

Abstract

We propose that the Universe created from "nothing" with relatively small particles number and quickly relaxed to quasiequilibrium state at the Planck parameters. The classic cosmological solution for this Universe with Lambda-term has two branches divided by the gap. The quantum process of tunneling between the cosmological solution branches and kinetic of the second order relativistic phase transition in supersymmetric SU(5) model on the GUT scale are investigated by numerical methods. Einstein equations was solved together with the equations of relaxation kinetics. Other quantum geometrodynamics process (the bounce from singularity) and the Wheeler- De Witt equation are investigated also. For the formation of observable particles number the model of the slowly swelling Universe in the result of the multiple reproduction of cosmological cycles is arised naturally.
