The future of a a-universe

AuthorsGonzález-Díaz, Pedro F. ; Sigüenza, Carmen L.
Issue Date2005
PublisherWorld Scientific Publishing
CitationInternational Journal of Modern Physics D 14: 1649-1655 (2005)
AbstractIt is argued that the accretion of phantom energy onto a wormhole in a universe with a positive cosmological constant leads also to a gradual increase of the wormhole throat radius, which eventually overtakes the super-accelerated expansion of the universe and becomes infinite at a time in the future before the big rip. Thus, the universe as a whole can time travel toward the past or the future. © World Scientific Publishing Company.
