Wormhole in the Milky Way galaxy with global monopole charge

Abstract

Abstract Wormholes are tunnels or short-cuts in space-time, and their existence is very important for human civilization to express the vastness of space and time. So, it is necessary to analyze our own Milky Way galaxy if it can harbour any wormhole. This work is dedicated to the existence of wormhole geometry(at least theoretically) in the bulge and halo of the Milky Way Galaxy. The structure and existence of wormholes are verified in both the bulge and the halo region of the Milky Way galaxy (MWG). Different dark matter profiles like pseudo-isothermal, NFW and Universal Rotational Curve (URC) are analyzed to harbour these cosmic tunnels. Three kinds of redshift functions are used for each dark matter profile with the global monopole charge to cover all the possibilities of MWG supporting wormhole geometry.
