On the status of wormholes in Einstein's theory
Peter K. F. Kuhfittig
It has been claimed that wormholes are just as good a prediction of Einstein's theory as black holes, but they are subject to severe restrictions from quantum field theory. The pur…
Supporting traversable wormholes: the case for noncommutative geometry
Peter K. F. Kuhfittig
While wormholes may be just as good a prediction of Einstein's theory as black holes, they are subject to severe restrictions from quantum field theory. In particular, a wormhole c…
Macroscopic noncommutative-geometry wormholes as emergent phenomena in gravity
Peter K. F. Kuhfittig
Noncommutative geometry, an offshoot of string theory, replaces point-like particles by smeared objects. These local effects have led to wormhole solutions in a semiclassical setti…
Revisiting wormholes supported by two non-interacting fluids
Peter K. F. Kuhfittig
This paper extends several previous studies of wormholes supported by two non-interacting fluids beginning with a combined model of ordinary matter and phantom dark energy with an…
Dark-energy wormholes in generalized Kaluza-Klein gravity
Peter K. F. Kuhfittig
This paper discusses traversable wormholes in a dark-energy setting by starting with a model due to Sung-Won Kim. This model, based on the Friedmann-Lemaitre-Robertson-Walker model…
Noncommutative-geometry wormholes based on the Casimir effect
Peter K. F. Kuhfittig
While wormholes are as good a prediction of Einstein's theory as black holes, they are subject to severe restrictions from quantum field theory. In particular, holding a wormhole o…
