Astrophysics of Wormholes
We consider the hypothesis that some active galactic nuclei and other compact astrophysical objects may be current or former entrances to wormholes. A broad mass spectrum for astrophysical wormholes is possible. We consider various new models of the static wormholes including wormholes maintained mainly by an electromagnetic field. We also discuss observational effects of a single entrance to w...
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 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 کاملHilbert space of wormholes.
Wormhole boundary conditions for the Wheeler-DeWitt equation can be derived from the path integral formulation. It is proposed that the wormhole wave function must be square integrable in the maximal analytic extension of minisuperspace. Quantum wormholes can be invested with a Hilbert-space structure, the inner product being naturally induced by the minisuperspace metric, in which the Wheeler-...
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...
