]]The Kasner metric corresponds to a flat homogenous but anisotropic space in which all volumes increase with time in such a way that the linear distances along two axes "y" and "z" increase while the distance along the axis "x" decreases.The moment "t" = 0 causes a singularity in the solution; the singularity in the metric at "t" = 0 cannot be avoided by any reference frame transformation.
