description | We construct a cosmological model consisting of a large number of identical, regularly spaced masses. The model does not rely on any averaging procedures, or on a global Friedmann-Robertson-Walker (FRW) background. It is a solution of Einstein's equations up to higher order corrections in a perturbative expansion, but has large-scale dynamics that can differ from those of FRW. In particular, we find solutions that are attracted toward expansion of the form R~t^0.71, as well as solutions without dark energy that undergo accelerating expansion at late-times. |
