Documents / Official release
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.

previous section. 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.
