Do most spiral galaxies harbor traversable wormholes connecting them in a sort of inter-galactic highway? It’s a central trope of science fiction movies like Cosmos and Interstellar, and the idea was introduced by Einstein and Rosen in 1935. But intergalactic wormhole bridges might also be real.
And a paper recently published in the Annals of Physics, “Possible existence of wormholes in the central regions of halos.” (Ann. Phys. 350 (2014) 561. DOI: 10.1016/j.aop.2014.08.003) suggests that most spiral galaxies might have wormholes.
An earlier study [1, 2] has demonstrated the possible existence of wormholes in the outer regions of the galactic halo, based on the Navarro-Frenk-White (NFW) density profile. This paper uses the Universal Rotation Curve (URC) dark matter model to obtain analogous results for the central parts of the halo. This result is an important complement to the earlier result, thereby confirming the possible existence of wormholes in most of the spiral galaxies.
