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