The arithmetic chaos of classical (super)gravity near a spacelike singularity is elevated to the quantum level via the construction of a cosmological quantum billiard system. Its precise formulation, together with its underlying algebraic structure, allows for a general analysis of the wavefunction of the universe near the singularity.

Abstract The main motivations for the need of constructing a theory of quantum gravity are presented. The chaper contains a discussion of the relevant scales (in particular, the Planck scale) and gives an overview of the experimental situation and the various approaches for quantizing gravity.

The Lagrangian required to calculate the lowest order quantum corrections to Einstein gravity in the framework of quantum non-local field theory (QNFT) is derived. The non-locally extended BRST gauge-transformations which leave this Lagrangian invariant are also derived.
