  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.
