Moreover, we give the maximal singularity-free atlas for the manifold with the metric under con- sideration. This atlas reveals many new features e.g. it turns out to describe an infinite lattice of asymptotically flat universes connected by black hole tunnels. 1 arXiv:1001.2226v1 [gr-qc] 13 Jan 2010 Abstract
