Abstract
We numerically evolve initial data modeling gravitational wave perturbations about a background Kasner cosmology. We examine the gravitational waves present in the initial data, and show that these inhomogeneities on the initial slice are not merely gauge effects. The evolution of these gravitational waves is gauge dependent, but we are able to separate the effects of the gauge terms from the true decay rate of the perturbations.Keywords
