In this paper we assume that general relativity provides an adequate description of gravitation on cosmological scales of interest; for discussions of modified gravity see [ref] , [ref] and references therein.] dark energy dominates the current epoch energy budget, but was less important in the past when non-relativistic (cold dark and baryonic) matter dominated.
