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.

Therefore, if the emergent spacetime/gravity approach turns out to be correct, then there will likely be a direct consequence to the physics of traversable wormholes that could dramatically alter the mechanism by which they are created and/or mitigate the requirement for negative energy. Until such new approaches are established and testable predictions published by their proponents, one cannot speculate on how the physics of traversable wormholes will be affected. Therefore, it is beneficial to stick to the outcome of the present study in terms of quantum field theory and general relativity theory, and outline what needs to be accomplished going forward in order to demonstrate a traversable wormhole in the lab. Going forward toward the demonstration of a traversable wormhole will require the following: • Generating Negative Energy in the Lab: Our assessment concludes that we already make small amounts of negative energy in the lab, but we do not yet know if we can access larger amounts for extended periods of time over extended spatial distributions for the purpose of engineering a traversable wormhole. In this regard we propose the following options for further exploration. • Squeezed quantum vacuum generators: A dedicated research program to develop the two negative energy generator concepts described in Section 111-B-2 will need to be established in order to evolve state-of-the-art quantum optics technology towards producing higher magnitudes of negative energy as well as special techniques required to separate out any positive energy fluxes that accompany the negative energy fluxes. Specifically, the Rabeau et al. (Reference 48, 49) and Ries et al. (Reference 50) experimental programs should be followed as a template toward this goal. Quantum optics technology via high power fiber lasers, resonators, amplifier stages, beam conditioning stages, etc., are rapidly advancing. So research should be conducted in parallel to invent additional ways to produce negative energy via innovative quantum optics. • Casimir effect: Even though the standard electromagnetic Casimir effect is feeble, and thus not likely to contribute to a traversable wormhole engineering program, there are still a number of other electromagnetic and non-electromagnetic Casimir effects described in Section 111-B-4 that require further study. These other Casimir effects have not been explored with an eye toward testing them in the lab, and so there could be important new information yet to be uncovered. • Moving Mirrors (a.k.a. the dynamical Casimir effect): Even though this concept was identified (Section 111-B-5) as being too feeble to produce any useful flux of negative energy, the observable effects due to the change in the boundary conditions (e.g., moving mirrors/cavity walls) of quantum fields provide crucial information on the quantum vacuum at the macroscopic level. Theoretical and laboratory efforts are underway to understand the dissipative effects of vacuum fluctuations (Reference 77-78). This dissipation mechanism should induce irradiation of photons, a phenomenon also known as the dynamical Casimir effect. This can be understood both as the creation of particles under non-adiabatic changes in the boundary conditions of quantum fields, or as classical parametric amplification with the zero- point energy of a vacuum field mode as an input state.
