Abstract

Kasner cosmology is a vacuum and anisotropically expanding spacetime in the general relativity context. Here I explore such a cosmological model in another context, the bumblebee model, where the Lorentz symmetry is spontaneously broken. By using the bumblebee context it is possible to justify the anisotropic feature of the Kasner cosmology. Thus, the origin of the anisotropy in this cosmological model could be in the Lorentz symmetry breaking.
