String reveals secrets of universe

TL;DR

This paper explores string cosmology, highlighting its unique features such as the absence of phase transitions and a cyclic universe, contrasting with standard cosmological models.

Contribution

It introduces a string cosmology model with no phase transition and cyclic behavior, differing from traditional cosmological theories.

Findings

No phase transition between radiation and matter dominated phases

Universe exhibits cyclic behavior similar to brane cyclic cosmology

Features differ significantly from standard cosmology

Abstract

Stringy cosmology displays features that are different from standard cosmology. One may be surprised in that in this scenario there is no phase transition between the radiation dominated phase and matter dominated phase and the universe is cyclic similar to brane cyclic cosmology.
