Bouncing universe scenario in f(Q,T) gravity model
Abstract
In this paper, we investigate the bouncing universe in a modified gravity model f(Q,T). 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 f(Q,T) gravity model, then the bouncing universe scenario according to the f(Q,T) gravity model in some special functions is analyzed in detail. We find that in which condition of parameters space, bouncing occurs.
