Analysis of initial singularity admitting viable bounce models

This research investigates the non-singular cosmic bounce models corresponding to Bianchi type-I spacetime in the framework of symmetric teleparallel theory. A specific functional form of this modified theory is used to examine the dynamics of bouncing cosmology. This study formulates the modified field equations and considers various parametric values to obtain feasible solutions. We examine the behavior of different cosmic bounce models corresponding to different scale factors and Hubble parameters, which resolves the big bang singularity as these parameters support the cyclic universe, there is a transition from an earlier contraction phase to another expansion phase. Furthermore, we investigate the behavior of energy density and pressure to comprehend the attributes of dark energy. The comprehensive analysis of equation of state parameter is also studied to determine the evolutionary eras of the universe. Our results indicate that the symmetric teleparallel theory describes cosmic expansion near the bouncing point.
