abstract
In this letter we obtain wormhole solutions from the Karmarkar condition in $f(Q)$ gravity formalism, in which $Q$ is the nonmetricity scalar. We show that the combination of such ingredients provides us the possibility of obtaining traversable wormholes satisfying the energy conditions. Our results contribute to $f(Q)$ gravity ascension, that was recently ignited by the natural prediction of early and late-time stages of universe expansion acceleration in the formalism.

Observing of background electromagnetic radiation of the real sky through the throat of a wormhole
A simulation shows that a nearby wormhole mouth would project a lensed image of the real CMB sky and Milky Way inside its silhouette, offering a possible observational signature distinct from a black hole.
