A string cosmological model based on Bianchi VI0 inhomogeneous bifurcation theory has been explored in general relativity, with a perfect fluid distribution model. To accomplish the task of obtaining the deterministic solution to Einstein's field equations, we suppose that the inhomogeneous generalization of Bianchi type VI0 with density and pressure may be used, and the model obtained will be the expanding, shearing, and spinning of the universe. In addition, talk about the model's physical and geometrical properties so that you can better understand how it works.
