# Possible formation of wormholes from dark matter in an isothermal galactic halo and void

## TL;DR

This paper explores the theoretical possibility that dark matter in galactic halos and voids could support traversable wormholes by violating the null energy condition, using solutions derived from Einstein's equations.

## Contribution

It presents new wormhole solutions in isothermal galactic halos and voids, linking dark matter distributions with wormhole physics through Einstein field equations.

## Key findings

- Null energy condition is violated in these solutions
- Wormholes can be supported by dark matter in galactic halos
- Redshift functions derived from flat rotation curves are key

## Abstract

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. In this paper, we have obtained such wormhole solutions in an isothermal galactic halo, as well as in a void. We have shown that the null energy condition is violated, with the help of a suitable redshift function obtained from flat galactic rotation curves.
