Inflationary cosmology and the scale-invariant spectrum

摘要

The claim of inflationary cosmology to explain certain observable facts, which the Friedmann-Roberston-Walker models of 'Big-Bang' cosmology were forced to assume, has already been the subject of significant philosophical analysis. However, the principal empirical claim of inflationary cosmology, that it can predict the scale-invariant power spectrum of density perturbations, as detected in measurements of the cosmic microwave background radiation, has hitherto been taken at face value by philosophers.
