Dynamic wormholes and Energy Conditions

TL;DR

This paper presents exact solutions for non-static wormholes that satisfy weak and dominant energy conditions, suggesting they require less exotic matter than static wormholes, with implications for their physical plausibility.

Contribution

It introduces a new class of dynamic wormhole solutions that obey energy conditions, reducing the need for exotic matter compared to static models.

Findings

Non-static wormholes can satisfy energy conditions.

Dynamic wormholes require less exotic matter.

Potential for more physically plausible wormhole models.

Abstract

A class of exact solutions of the Einstein field equations representing non-static wormholes that obey the {\em weak and dominant energy conditions } is presented. Hence, in principle, these wormholes can be built with less exotic matter than the static ones.
