Could wormholes form in dark matter galactic halos?
read the original abstract
We estimate expression for velocity as a function of the radial coordinate $r$ by using polynomial interpolation based on the experimental data of rotational velocities at distant outer regions of galaxies. The interpolation technique has been used to estimate fifth degree polynomial followed by cubic spline interpolation. This rotational velocity is used to find the geometry of galactic halo regions within the framework of Einstein's general relativity. In this letter we have analyzed features of galactic halo regions based on two possible choices for the dark matter density profile, viz. Navarro, Frenk \& White (NFW) type~\citep{Navarro1996} and Universal Rotation Curve (URC) ~\citep{Castignani2012}. It is argued that spacetime of the galactic halo possesses some of the characteristics needed to support traversable wormholes.

Traversable Wormholes Supported by Entropy-Inspired Effective Matter Sectors
Modified entropy profiles from Barrow, Tsallis, Kaniadakis, logarithmic, and exponential entropies can serve as effective sources for traversable wormholes.
