Charged wormholes in spacetimes of embedding class one
Peter K. F. Kuhfittig
The existence of charged black holes has suggested that wormholes may also be charged. The purpose of this paper is to construct a general model of a charged wormhole that proves t…
On wormholes in spacetimes of embedding class one
Peter K. F. Kuhfittig
An -dimensional Riemannian space is said to be of embedding class if is the lowest dimension of the flat space in which the given space can be embedded. A spherically…
Possible existence of time machines in a five-dimensional spacetime
Peter K. F. Kuhfittig
The idea of constructing a time machine is not new and even received a boost thanks to the realization that a traversable wormhole could be converted to a time machine. It was show…
Slowly evolving noncommutative-geometry wormholes
Peter K. F. Kuhfittig
This paper discusses noncommutative-geometry wormholes in the context of a cosmological model due to Sung-Won Kim. An ansatz suggested by the Friedmann-Lemaitre-Robertson-Walker (F…
On the nature of exotic matter in Morris-Thorne wormholes
Peter K. F. Kuhfittig
It is well known that phantom energy, which is characterized by the equation of state , , can support Morris-Thorne wormholes since it leads to a violation of the null…
Noncommutative-geometry wormholes with isotropic pressure
Peter K. F. Kuhfittig
The strategy adopted in the original Morris-Thorne wormhole was to retain complete control over the geometry at the expense of certain engineering considerations. The purpose of th…
