Wormholes with low energy density
Peter K. F. Kuhfittig
In spite of their speculative nature, traversable wormholes are a topic of interest that started with the Einstein-Rosen bridge in 1935 and became a major research area with the in…
A viable wormhole model in a five-dimensional spacetime
Peter K. F. Kuhfittig
This paper generalizes two of the author's earlier wormhole solutions that are characterized by an extra spatial dimension. This paper adds the assumption that the components of th…
Macroscopic traversable wormholes: minimum requirements
Peter K. F. Kuhfittig
While wormholes are just as good a prediction of Einstein's theory as black holes, they are subject to severe restrictions from quantum field theory. To allow for the possibility o…
Thin-shell wormholes admitting conformal motions in spacetimes of embedding class one
Peter K. F. Kuhfittig
This paper discusses the feasibility of thin-shell wormholes in spacetimes of embedding class one admitting a one-parameter group of conformal motions. It is shown that the surface…
Revisiting the boundary conditions for a Morris-Thorne wormhole
Peter K. F. Kuhfittig
In physical science, the concept of \emph{emergence} is often used to describe phenomena that occur at macroscopic scales but not at microscopic scales. The latter is usually refer…
Wormholes supported by small extra dimensions
Peter K. F. Kuhfittig
Holding a Morris-Thorne wormhole open requires a violation of the null energy condition, calling for the need for so-called exotic matter near the throat. Many researchers consider…
