The dark matter surrounding galaxies might be the exact 'glue' needed to prop open a wormhole you could actually travel through.

Why it matters
Wormholes are theoretical shortcuts through space, but staying open usually requires 'exotic matter' that shouldn't exist. This study shows that the specific density profiles of dark matter observed in real galaxies could provide the necessary energy to support a stable, traversable gateway.
From the abstract
We investigate spherically symmetric and static traversable wormholes supported by exotic matter, focusing on solutions sourced by physically motivated dark matter energy density profiles. Considering the Thomas-Fermi-type distribution, we construct explicit forms of the shape function $b(r)$ and analyze the resulting radial and tangential pressures, carefully addressing the requirements of the flare-out condition at the throat and the absence of horizons. We explore zero-tidal-force configurati
