Bounce and wormholes

TL;DR

This paper explores whether bouncing cosmological theories can produce traversable wormholes, finding that two models do allow such solutions while a third does not.

Contribution

It demonstrates that certain bouncing cosmological theories can admit static traversable wormhole solutions, expanding understanding of their possible spacetime structures.

Findings

Two bouncing models support traversable wormholes.

One model does not admit wormhole solutions.

Results suggest specific theories can produce stable wormholes.

Abstract

We investigate if theories yielding bouncing cosmological models also generate wormhole solutions. We show that two of them present sensible traversable static wormhole solutions, while for the third possibility such solutions are absent.
