### 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 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.
