On the Possibility of the Existence of Wormholes in Nature

Abstract: So far, many exotic predictions of Einstein's equations have been corroborated, with one exception: wormholes (WHs). In this work, we analyze an exact solution to the Einstein-Maxwell-Dilaton or Phantom equations representing rotating WHs. We introduce a ring singularity that, like other solutions, satisfies Wormhole Cosmic Censorship, i.e., the singularity is causally disconnected. We show that this WH is traversable through the poles, where tidal forces and the magnetic field are reasonably small. We satisfy the energy conditions for the dilaton-like solution. We argue that if dilaton-like interactions can exist in nature, for example, if extra dimensions exist as in superstring theory, WHs are a natural realistic prediction of Einstein's equations, and we should be able to observe them somehow, probably as black hole mimics. We give some examples of realistic WHs that could be observed in nature.
