Seeking connections between wormholes, gravastars, and black holes via noncommutative geometry
Peter K. F. Kuhfittig, Vance D. Gladney
Noncommutative geometry, an offshoot of string theory, replaces point-like objects by smeared objects. The resulting uncertainty may cause a black hole to be observationally indist…
More on traversable wormholes sustained by an extra spatial dimension
Peter K. F. Kuhfittig
This paper extends an earlier study by the author [Phys. Rev. D, vol. 98, 064041 (2018), arXiv:1809.01993] in several significant ways. To begin with, the extra spatial dimension i…
Possible formation of wormholes from dark matter in an isothermal galactic halo and void
Nayan Sarkar, Susmita Sarkar, Farook Rahaman +2
It is well known that traversable wormholes are valid solutions of the Einstein field equations, but these structures can only be maintained by violating the null energy condition.…
Thin-shell wormholes from Kiselev black holes
Peter K. F. Kuhfittig
This paper discusses the theoretical construction of thin-shell wormholes from Kiselev black holes. We assume a barotropic equation of state for the exotic matter on the shell. Whi…
