This Defense Intelligence Reference Document, DIA-08-1004-004, is dated 6 April 2010. The Acquisition Support Division of the Defense Intelligence Agency's Defense Warning Office prepared it as one in a series of advanced technology reports from FY 2009 under the Advanced Aerospace Weapon System Applications Program. It reviews the physics of traversable wormholes and flat-faced "stargate" solutions, and it covers how negative energy might be generated in the laboratory. It concludes that the key technical challenge is identifying and producing exotic matter.
From the source:Release of 2026-09-18 Incident: 4/6/10, Las Vegas, Nevada. Released with redactions. This document is a Defense Intelligence Reference Document (DIRD), a technical reference format used by the Defense Intelligence Agency (DIA) to capture baseline knowledge on a specific topic for later analytic use. DIRDs are best understood as reference and synthesis products rather than as original research. It is one of 38 DIRDs produced under the Advanced Aerospace Weapon System Applications Program (AAWSAP) between 2009 and 2011. Because AAWSAP’s scope permitted a broad range of supporting topics, not every DIRD in the series directly concerns aerospace systems or future threat assessment. The following summary reflects the DIRD’s scope and framing at the time of writing and should not be read as implying current validation of the concepts discussed. This DIRD examines traversable wormholes and “stargates” as hypothetical spacetime structures within general relativity that theoretically offer a means of faster-than-light travel or communication. The report focuses extensively on the requirement for exotic, negative-energy matter to stabilize and keep such geometries open for the passage of macro-scale objects. It reviews standard wormhole models, describes a flat-throated “stargate” variant, and argues that violations of general relativity's standard energy conditions do not physically rule such structures out, citing microscopic, transient negative-energy effects observed in Casimir-type laboratory phenomena. However, the document acknowledges that the transition from microscopic quantum fluctuations to macroscopic engineering is an unresolved barrier. While small-scale negative-energy effects are observable, there is no known mechanism to generate, concentrate, or stabilize the amounts of exotic matter proposed to be required to sustain a traversable macroscopic wormhole. Ultimately, while the paper frames wormhole concepts within accepted relativistic physics, it confirms that the gap between theoretical models and any realizable technology remains enormous.

include models for the super-radiant amplification of photons with particular
emphasis on its dynamics and the optimization of the involved parameters.
Experimental concepts being pursued will try to reveal directly the presence of a
non-empty vacuum by using a specifically designed device to amplify the virtual
vacuum photons and produce real electromagnetic radiation via the parametric
amplification of the vacuum fluctuations in an electromagnetic cavity. The 'amplifier'
is a boundary undergoing an oscillation, and hence radiates energy due to the
dissipative action against the vacuum photons. This line of investigation could serve
as a very useful probe to explore the possibility of generating large fluxes of
negative energy. It may be expected that a laboratory demonstration of the
dynamical Casimir effect will occur before 2012.
• Dirac field states: As described in Section III-A, this involves either the
superposition of two single particle electron states or the superposition of two multi
electron-positron states (Reference 29, 30). This is still a nascent topic of study in
quantum field theory. However, mankind already possesses a great deal of
technology that is dedicated to the manipulation and storage of electrons and
positrons via solid state/condensed matter devices and particle accelerators. This
research topic should be supported in order to establish how it could contribute to
an experimental traversable wormhole program.
• Quantum coherence effects: Other types of quantum coherence effects not already
identified or invented should be theoretically developed and explored for the
possibility of finding new free-field or interacting field configurations that produce a
significant magnitude of negative energy which could be produced by technological
means.
• Detecting Negative Energy in the Lab: In Section IV-C this paper identified
proposals for observing negative energy in outer space and in the laboratory, but
further work is needed to downscale astronomical techniques for use at the lab scale,
and we need to firm up our understanding of how lab detectors will respond to
negative energy in situ. A first step in the latter direction was recently proposed by
Marecki (Reference 79) who generalized the analysis of the output of balanced
homodyne detectors (BHDs). The most important feature of these devices is their
ability to quantify the quantum vacuum fluctuations of the electric field because the
output of BHDs provides information on the one- and two-point functions of
arbitrary states of quantum fields. Marecki computed the two-point function and the
associated spectral density for the ground state of the quantum electric field in
Casimir geometries, and predicts a position- and frequency-dependent pattern of
BHD responses if a device of this type is placed inside a Casimir cavity. The
proposed device allows for the direct detection of quantum vacuum fluctuations and
provides a spatial mapping of the negative energy contained inside the cavity. This
offers a potential new characterization of ground states in Casimir geometries, which
would provide an understanding of the negative energy densities present in some
regions in these geometries.
• Trapping and Storing Negative Energy: Ford and Roman (Reference 10) have only
superficially addressed this topic, and there is very little technical literature that
addresses it fully. A theoretical program to develop the physics and technology of
trapping and storing negative energy will need to be supported, and such a program
should be guided by the use of laboratory detectors such as the one proposed in the
