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.

the allowable spatial distributions of negative energy. And there were found to be
allowable negative energy distributions in which observers would never encou nter the
accompanying positive energy distribution so long as the QI restrictions and
correspond ing energy conditions are violated . The extent to which the results of Borde
et al. 's analysis can be generalized to a four-d imensional curved spacetime (with or
without boundaries) and interacting fields remain unsolved.
C. OBSERVING NEGATIVE ENERGY IN THE LAB
Negative energy should be observable in lab experiments . The presence of naturally
occurring negative energy regions in space is pred icted to produce a unique signature
correspond ing to lensing, chromaticity and intensity effects in micro- and macro-l ensing
events on galactic and extragalactic/cosmological scales (Reference 66-71) . It has been
shown that these effects provide a specific signature that allows for discrimination
between ordinary (positive energy) and negative energy lenses via the spectra l analysis
of astronomical lensing events. Theoretical modeling of negative energy lensing effects
has led to intense astronomical searches for naturally occurring traversable wormholes
in the universe. Computer model simulations and comparison of their results with
recent satellite observations of gamma ray bursts (GRBs) has shown that putative
negative energy (i.e., traversable wormhole) lensing events very closely resemble the
main features of some GRBs. Other research has found that current observational data
suggests that large amounts of naturally occurring "exotic matter" must have existed
sometime between the epoch of galaxy formation and the present in order to (properly)
quantitatively account for the "age-of-the-oldest-stars-in-the-galactic halo" problem
and the cosmological evolution parameters (Reference 60).
When background light rays strike a negative energy lensing region, they are swept out
of the central region thus creating an umbra region of zero intensity. At the edges of
the umbra the rays accumulate and create a rainbow-like caustic with enhanced light
intensity. The lensing of a negative energy region is not analogous to a diverging lens
because in certa in circumstances it can produce more light enhancement than does the
lensing of an equivalent positive energy region. Real background sources in lensing
events can have non-uniform brightness distributions on their surfaces and a
dependency of their emission with the observing frequency. These complications can
result in chromaticity effects, i.e., in spectral changes induced by differential lensing
during the event. The quantification of such effects is quite lengthy, somewhat model
dependent, and with recent application only to astronomical lensing events. Suffice it to
say that future work is necessary to scale down the predicted lensing parameters and
characterize their effects for lab experiments in which the negative energy will not be of
astronomical magnitude. Present ultrahigh-speed optics and optical cavities, lasers,
photonic crystal (and related switching) technology, sensitive nano-sensor technology,
and other techniques are very likely capable of detecting the very small magnitude
lensing effects expected in lab experiments.
A non-optical scheme for detecting negative energy in experiments was recently
reported by Davies and Ottewill (Reference 72) who studied the response of switched
particle detectors to static negative energy densities and negative energy fluxes. Their
model is based on a free (massless) scalar field in flat four-dimensional Minkowski
spacetime and utilized a simple generalization of the standard monopole detector,
which is switched on and off to concentrate the measurements on periods of isolated
negative energy density (or negative energy flux). The detector model includes an
