Could a foliation by constant mean curvature hypersurfaces cover the existence of most observers in our part of spacetime?

Abstract

We present a foliation by constant mean curvature hypersurfaces of a de Sitter space with a thin-wall Coleman-De Luccia bubble of de Sitter space inside, which covers the existence of most observers in our part of spacetime if we are placed in the region outside the bubble.
