One of the major advantages of the inflationary scenario is that it provides a mechanism for the generation of density perturbations in the early universe. These perturbations leave an imprint on the cosmic background radiation which has been observed. It has been shown that physical processes at and beyond the Planck scale could affect the spectrum of the density perturbations and thus leave an imprint on the cosmic background radiation. The questions of what types of imprints are possible and under what conditions they can be observed will be addressed.
