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.

These are the Einstein field equations for a traversable wormhole that is produced by a
thin shell of localized matter. Equations (3a-c) imply that (for ~ a convex
hypersurface) one is dealing with negative surface energy density and negative surface
tensions. This is exotic matter! The negative surface tension (= positive outward
pressure, a.k.a. gravitational repulsion) is required to keep the throat open and stable
against collapse. To make this thin shell wormhole entirely flat requires that one
chooses the throat oD. to have at least one fl at face (picture the thin shell in Figure 5
becoming flat). On that face the two principal radii of curvature become p1 = p2 = oo as
required by standard three-dimensional geometry; therefore, substituting this
requirement into Equations (3a-c) gives:

which is a remarkable result. This
means that a traveler encountering and
going through such a wormhole
stargate will feel no tidal gravitational
forces and see no exotic matter
threading the throat. A traveler stepping
through the throat will simply be
shunted into another remote spacetime
region or into another universe (note:
the Einstein field equation does not fix
the spacetime topology, so it is possible
that wormholes are inter-universe as
well as intra-universe tunnels).
Therefore, one can construct a stargate
by generating a thin shell or surface
layer of exotic matter much like a thin
film of soap stretched across a loop of
wire.
C. WHAT A WORMHOLE LOOKS
LIKE IN THE REAL WORLD
The exotic matter threading a
traversable wormhole throat produces
repulsive gravity, which will then deflect
light rays going through and around it.
The entrance to the spherically symmetric Morris & Thorne wormhole looks like a
sphere that contains the mirror image of a whole other universe or remote region
within our own universe, incredibly shrunken and distorted (see Figure 6). This is an
