International Conference on Quantum Gravity

This conference is mostly about quantum gravity and its intrinsic nonlocal feature, but also about general gravitational theories beyond Einstein's gravity, black holes, cosmology, and observational tests. 

It is well known that any fundamental theory is nonlocal at the quantum level, namely the quantum effective action is a "very nonlocal” functional. Moreover, quantum mechanics itself is intrinsically nonlocal. Furthermore, when we try to construct a consistent theory for quantum gravity non locality turns out to be unavoidable. Indeed, in our days we have several consistent proposals for quantum gravity: String Theory, Loop Quantum Gravity, Nonlocal Quantum Gravity, Asymptotically Safe Quantum Gravity, etc., and all of them are nonlocal. In this conference we will try to make the point of the current understanding of several approaches to quantum gravity with particular attention to the locality paradigm at short distance. In particular we will try to point out issues and ways to overcome them.

However, besides the fundamental theoretical problems, other topics of the conference are about the spacetime singularities' issue, black holes at the classical and quantum level, the information loss problem, and the cosmological implications at short and large distance of a large class of local and nonlocal gravitational theories.
