A note about the back-reaction of inhomogeneities on the expansion of the Universe
arXiv:0906.4278
Abstract
In this short note we summarize the arguments against a significant back-reaction of inhomogeneities on the acceleration of the Universe. We also present a quick way to access the importance of back-reaction using the Fourier space presentation of inhomogeneities and properties of their power spectrum.
