Initial Fluctuation Spectrum

(the power spectral density of the early universe)

The Initial Fluctuation Spectrum is a power spectrum (Angular Power Spectrum?) representing the density fluctuations in the early universe, presumed to be the origin of the variation in the Cosmic Microwave Background (CMB) as well as the uneven density of the present universe. The cosmic Inflation model is a piece of the current explanation for the initial uneven density.
