Abstract
The standard big bang model of the universe is a very successful one supported by three major pieces of evidence:
-
the expansion of the universe, which constitutes the most natural interpretation of the redshift of galaxies,
-
the existence of a cosmic background of electromagnetic radiation, a relic of the primordial state of high density, pressure and temperature. The predicted spectrum of the cosmic microwave background is that of a blackbody with temperature of 2.7 K, in remarkable agreement with the observations, and
-
primordial nucleosynthesis: the relative abundances of H, He, and a few other light elements are predicted and are in agreement with observations.

References
Intermediate inflation [75, 658, 84] corresponds to an expansion of the universe which interpolates between exponential and power-law and yields a Harrison-Zeldovich spectrum (n = 1), or a blue spectrum (n > 1) of density perturbations.
