On Possible Origin of an Artificial Wormhole

Abstract

We assume the picture in which a vacuum is filled with virtual wormholes. The presence of external fields changes the distribution of virtual wormholes and, in principle, allows for the creation of a coherent structure that can work as an actual wormhole or the Alcubierre bubble. We establish the explicit functional relationship between the external field and the distribution of virtual wormholes in vacuum. This opens a way for examining the question about the possibility of the artificial creation of such objects in a laboratory. We show that weak and quasihomogeneous fields suppress the density of wormholes and cannot be used. We also discuss the existence of a threshold for the intensity of an external field beyond which the formation of wormhole-type structures becomes possible.
