Probing kinematics and fate of Bianchi type I universe in Brans–Dicke theory
Abstract
In this paper, we examine the existence of Bianch type I Brans–Dicke universe by performing statistical test from and SN Ia observational data sets. We find that anisotropic Brans-Dicke ( BD) model provides a reasonable fit with observational data. In addition to , we also use Akaike information creation (AIC) and Bayes information creation (BIC) to determine the values of best fit parameters. The model under consideration represents a transitioning universe from early decelerating phase to current accelerating phase. We obtain the present age of the universe as 13.732 Gyrs, which is in good agreement with WMAP observations. The physical behavior of particle horizon and parameter of the derived model are also discussed.
