Lemaître-Tolman-Bondi cosmological wormhole

I. Bochicchio, Valerio Faraoni
2010 Physical Review D  
We present a new analytical solution of the Einstein field equations describing a wormhole shell of zero thickness joining two Lemaıtre-Tolman-Bondi universes, with no radial accretion. The material on the shell satisfies the energy conditions and, at late times, the shell becomes comoving with the dust-dominated cosmic substratum.
