Bouncing universe scenario in f(Q,T) gravity model

Abstract

In this paper, we investigate the bouncing universe in a modified gravity model [Formula: see text]. The bouncing universe theory posits that the universe goes through periodic expansions and contractions, with a “bounce” occurring at the end of each contraction that leads to a new expansion. This theory suggests that our universe didn’t emerge on its own out of nothing, but is instead the latest in a series of universes that have been expanding and contracting for eternity. It has gained renewed interest in recent years as a potential alternative to the Big Bang theory, which suggests that our universe began with a massive expansion from a singularity. According to the above explanations, first, we review of [Formula: see text] gravity model, then the bouncing universe scenario according to the [Formula: see text] gravity model in some special functions is analyzed in detail. We find that in which condition of parameters space, bouncing occurs.
