Observers in an accelerated universe

If the current acceleration of our Universe is due to a cosmological constant, then a Coleman–De Luccia bubble will nucleate in our Universe. In this work, we consider that our observations could be likely in this framework, consisting of two infinite spaces, if a foliation by constant mean curvature hypersurfaces is taken to count the events in the spacetime. Thus, we obtain and study a particular foliation, which covers the existence of most observers in our part of spacetime.
