Interpenetrating subspaces as a funnel to extra space

Abstract

New solution for two interpenetrating universes is found. Higher derivative gravity acting in 6-dimensional space is the basis of the study that allows to obtain stable solution without introducing matter of any sort. Stability of the solution is maintained by a difference between asymptotic behavior at spacial infinities. For an external observer such a funnel looks similar to a spherical wormhole.Comment: 10 pages, 5 figures, accepted for publication in Phys. Lett. B, revised versio
