Quantum Cosmology

Abstract

Up to this point, the cosmological model has been a kind of classical framework for processes that are mainly microscopic. These in turn have determined the evolution of the classical framework through the history of the matter content. Such a division between frame and content presupposes that the orders of magnitude of the characteristic lengths, times or energies are distinctly different. Since the time of inflation, such a supposition may be justified. However, what happened before inflation began? Should we ever expect an answer? After all, we recall that the goal of explaining the universe through its dynamics requires that the conclusions about its early history become more and more fuzzy and shaky the further we dig into the past, and finally must become empty.
