Cosmological Wormhole: An analytical description
Subenoy Chakraborty, Madhukrishna Chakraborty
TL;DR
This paper provides an analytical model of traversable wormholes in non-static spherically symmetric spacetime supported by anisotropic fluid, showing that different red-shift functions lead to similar wormhole configurations and allowing for emergent universe scenarios.
Contribution
It offers a novel analytical description of traversable wormholes supported by anisotropic fluid in dynamic spacetime, highlighting the equivalence of different red-shift functions.
Findings
Trivial and non-trivial red-shift functions yield identical wormhole configurations.
Emergent universe scenarios are possible in both cases.
The model advances understanding of wormhole solutions in evolving spacetimes.
Abstract
An attempt has been made to have an analytical description for possible traversable wormhole in non-static spherically symmetric space-time supported by anisotropic fluid. Both trivial and non-trivial choices of the red-shift function result in identical WH configuration and it is possible to have emergent scenario for evolution of the background space-time in both the cases.
