Comments on Long-Wavelength Backreaction and Dark Energy
E. W. Kolb, S. Matarrese, A. Riotto
Abstract
In this brief note we comment on a recent attempt by Martineau and Brandenberger (astro-ph/0510523) to explain the acceleration of the Universe using the back-reaction of long-wavelength perturbations associated with isocurvature perturbation modes.
