It builds on the generalized notion of renormalizability naturally arising from the Wilsonian Renormalization Group.

Quantum Gravity on Foliated Spacetimesy requires the spacetime to be Lorentzian, the EAA is defined by means of a Euclidean path integral. In the context of Quantum Field Theory, the Lorentzian signature can be recovered by Wick-rotating all time-like quantities.

Conclusionsxed points of the renormalization group flow. On this basis, gravity may result in a finite and predictive quantum theory if its flow converges to a Non-Gaussian Fixed Point (NGFP) in the ultraviolet limit.

Similarly, General Relativity provides a successful description of the gravitational interaction and most of its predictions have been confirmed by observations.

For instance, a systematic study of scattering amplitudes in Quantum Electrodynamics show that, due to the singular high-energy behavior of the theory, Feynman diagrams containing loops result in an infinite contribution to the transition amplitude.
