A POSITIVE COSMOLOGICAL CONSTANT IN STRING THEORY THROUGH AdS/CFT WORMHOLES
There are two important examples of physical systems which violate the strong energy condition : Universes (like, it would seem, our own) with a positive cosmological constant, and wormholes. We suggest that a positive cosmological constant can be reconciled with string theory by considering wormholes in string backgrounds. This is argued in two directions : first, we show that brane-worlds wit...
متن کاملCylindrical wormholes
It is shown that the existence of static, cylindrically symmetric wormholes does not require violation of the weak or null energy conditions near the throat, and cylindrically symmetric wormhole geometries can appear with less exotic sources than wormholes whose throats have a spherical topology. Examples of exact wormhole solutions are given with scalar, spinor and electromagnetic fields as so...
متن کاملWormholes 1 WORMHOLES TO ORGANIZATIONAL EXPERTISE: THE MANAGEMENT OF METAKNOWLEDGE
Current theories on organizational learning, knowledge representation, and knowledge management conceive organizational knowledge as shared knowledge. Furthermore, the purpose of managing knowledge in organizations is to share the not-yet-shared. The scope of this paper is to analyze current problems in the representation and management of organizational knowledge. We will outline a concept tha...
متن کاملInflating Lorentzian wormholes.
It has been speculated that Lorentzian wormholes of the Morris-Thorne type might be allowed by the laws of physics at submicroscopic, e.g. Planck, scales and that a sufficiently advanced civilization might be able to enlarge them to classical size. The purpose of this paper is to explore the possibility that inflation might provide a natural mechanism for the enlargement of such wormholes to ma...
متن کاملWormholes in Simplicial Minisuperspace
We consider a simplicial minisuperspace modelling wormhole configurations. Such configurations result from a cut and paste procedure on two identical copies of the most relevant triangulation of our universe, namely the cone over α4, which is the simplest triangulation of S. The connecting space where the two copies are glued, acts as the throat of a wormhole connecting two distinct universes. ...
