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.

remains an open question.
One is presently unaware of any way to artificially generate gravitational squeezing of
the vacuum in the laboratory. This will be left for future investigation. However, it is
predicted to occur in the vicinity of astronomical matter. Naturally occurring traversable
wormholes in the vicin ity of astronomical matter would therefore become possible.
4. Vacuum Field Stress: Negative Energy from the Casimir Effect
The Casim ir effect is by far the easiest
and most well known way to generate
negative energy in the lab. The Casimir
effect that is fami liar to most people is
the force that is associated with the
electromagnetic quantum vacu um
(Reference 51). This is an attractive
force that must ex ist between any two
neutral (uncha rged), parallel, flat,
conducting surfaces (e.g., metallic
plates) in a vacuum. Th is force has been
well measured and it can be attributed
to a minute imbalance in the vacuum
elect romagnetic zero-point energy
density inside the cavity between the
conducting su rfaces versus the vacuum
electromagnetic zero-point energy
density in t he free-space region outside
of the cavity (Reference 52-54 ). See
Figure 12 for an illustration of t his
effect.
