Abstract
The quantum gravity processes that have taken place in the very early Universe are probably responsible for the observed large-scale cosmological perturbations. The comparison of the theory with the detected microwave background anisotropies favors the conclusion that the very early Universe was not driven by a scalar field with whichever scalar field potential. At the same time, the observations allow us to conclude that there is a good probability of a direct detection of the higher frequency relic gravitational waves with the help of the advanced laser interferometers.
