Abstract

We review different spacetimes that contain nonchronal regions separated from the causal regions by chronology horizons and investigate their connection with some importants aspects one would expect to be present in a final theory of quantum gravity, including: stability to classical and quantum metric fluctuations, boundary conditions of the Universe and gravitational topological defects corresponding to spacetime kinks.
