Phys. Rev. Lett. 53, 2445–2448 (1984)Smoothing Out Spatially Closed CosmologiesReceived 30 July 1984; published in the issue dated 17 December 1984 We discuss a smoothing-out procedure that deforms a family of locally inhomogeneous and anisotropic spatially closed cosmological models into closed Friedmann-Robertson-Walker universes. This gives a precise content to the averaging hypothesis tacitly assumed in cosmology by providing explicitly the correction terms to the physical sources induced on smoothing out the space-time geometry. The consequences of such terms on the dynamics of the Universe are discussed. © 1984 The American Physical Society URL:
