This Defense Intelligence Reference Document (DIA-08-1004-004), dated 6 April 2010, was produced by the Defense Intelligence Agency under its Advanced Aerospace Weapon System Applications (AAWSA) Program. It is one of a series of advanced technology reports from FY 2009. It reviews the general relativity physics of traversable wormholes and flat-faced "stargate" solutions for faster-than-light travel. It also covers the exotic negative energy these would need, proposed lab methods for generating it such as the Casimir effect and squeezed vacuum, and the constraints involved.

However, it is the opinion of the author that free-space negative energy sources appear to be a more desirable option for building traversable wormholes than stored negative energy. • Constructing Traversable Wormholes in the Lab: Einstein's General Theory of Relativity does not provide instructions on how to construct a traversable wormhole in space or inside a laboratory vacuum vessel. The Einstein general relativistic field equation only provides a prescription for designing a special, localized spacetime geometry and calculating the physical characteristics of a source of matter that is required to induce it. If one "zaps" a region of empty space with a beam of negative energy, will a traversable wormhole appear? One doesn't know. Maybe one has to poke a hole in space with an intense beam of negative energy, or maybe we have to use the negative energy to inflate a quantum spacetime fluctuation (allegedly in the form of a "geometric foam"). Theoretical studies need to be implemented to address this question and the author believes that empirical studies will be necessary to find the answer once we develop an intense source of negative energy.
