• TITLE: Wormholes Supported by a Combination of Normal and Quintessential Matter in Einstein and Einstein-Maxwell Gravity

  AUTHORS: Peter K. F. Kuhfittig

  KEYWORDS: Wormholes; Quintessential Matter; Einstein-Maxwell Gravity

  JOURNAL NAME: Journal of Modern Physics, Vol.4 No.1, January 18, 2013

  ABSTRACT: It is shown in the first part of this paper that a combined model comprising ordinary and quintessential matter can support a traversable wormhole in Einstein-Maxwell gravity. Since the solution allows zero tidal forces, the wormhole is suitable for a humanoid traveler. The second part of the paper shows that the electric field can be eliminated (Einstein gravity), but only by tolerating enormous tidal forces. Such a wormhole would still be capable of transmitting signals.
