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 [Formula: see text] and SN Ia observational data sets. We find that anisotropic Brans-Dicke ([Formula: see text] BD) model provides a reasonable fit with observational data. In addition to [Formula: see text], 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 [Formula: see text] parameter of the derived model are also discussed.
