The no-boundary proposal via the five-dimensional Friedmann-Lemaitre-Robertson-Walker model
Peter K. F. Kuhfittig, Vance D. Gladney
Hawking's proposal that the Universe has no temporal boundary and hence no beginning depends on the notion of imaginary time and is usually referred to as the "no-boundary proposal…
Stable wormholes on a noncommutative-geometry background admitting a one-parameter group of conformal motions
Peter K. F. Kuhfittig
When Morris and Thorne first proposed the possible existence of traversable wormholes, they adopted the following strategy: maintain complete control over the geometry, thereby lea…
Wormholes admitting conformal Killing vectors and supported by generalized Chaplygin gas
Peter K. F. Kuhfittig
When Morris and Thorne first proposed that traversable wormholes may be actual physical objects, they concentrated on the geometry by specifying the shape and redshift functions. T…
Wormholes with a barotropic equation of state admitting a one-parameter group of conformal motions
Peter K. F. Kuhfittig
The theoretical construction of a traversable wormhole proposed by Morris and Thorne maintains complete control over the geometry by assigning both the shape and redshift functions…
Possible existence of wormholes in the central regions of halos
Farook Rahaman, P. Salucci, P. K. F. Kuhfittig +2
An earlier study [Rahaman et al. (2014) & Kuhfittig (2014)] has demonstrated the possible existence of wormholes in the outer regions of the galactic halo, based on the Navarro-Fre…
Gravitational lensing of wormholes in noncommutative geometry
Peter K. F. Kuhfittig
It has been shown that a noncommutative-geometry background may be able to support traversable wormholes. This paper discusses the possible detection of such wormholes in the outer…
