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.

Figure 2 shows the embedding diagram
for a traversable wormhole that
connects two different universes (i.e.,
an inter-universe wormhole). The
bottom diagram in the figure is an intra-
universe wormhole with a throat that
connects two distant regions of our own
universe. These diagrams serve to aide
in visualizing traversable wormhole
geometry and are merely a geometrical
exaggeration.
There was originally one other criterion
for defining a traversable wormhole,
which was that it must be embedded Figure 2. Inter-Universe Wormhole (top) and Intrawithin the surround ing (asymptotically) Universe Wormhole (bottom).
flat spacetime. However, Hochberg and
Visser (Reference 4) proved that it is only the behavior near the wormhole throat that is
critical to understanding the physics, and that a generic throat can be defined without
having to make all the symmetry assumptions and without assuming the existence of
an asymptotically flat spacetime in which to embed the wormhole. Therefore, one only
needs to know the generic features of the geometry near the throat in order to
guarantee violations of the Null Energy Condition (NEC; see Section III for further
detail) for certain open regions near the throat. So one is free to place our wormhole
anywhere in spacetime because it is only the geometry and physics near the throat that
matters for any analysis. This fact led to the development of a number of different
traversable wormhole throat designs that are cubic shaped, polyhedral shaped, flat-face
shaped, generic shaped, etc. The reader should consult (Reference 3) for a complete
technical review of the various types (and shapes) of traversable wormhole solutions
found in general relativity theory.
One knows that one needs exotic or negative energy to create and thread open a
traversable wormhole. So in this regard, one asks what kind of wormhole one can make
with less effort. To answer this question one can relate the local wormhole geometry to
the global topolog ical invariant of the spacetime via the Gauss-Bonnet Theorem
(Reference 5). In the Gauss-Bonnet Theorem the local wormhole geometry is quantified
by the energy density, U (in geometrodynamic units, TJ = G = c = 1), threading the
wormhole throat plus a spatial curvature constant (for the throat). The global
topological invariant of spacetime is quantified by the Euler Number, xe, which is itself
defined in terms of the genus, g, representing the number of handles (or throats or
tunnels) a wormhole can be assigned. These two topological quantities are related via
xe = 2(1 - g). Therefore, the (static) wormhole Gauss-Bonnet relation is given by U :;;
xe/4 or U :;; (1 - g)/2 (Reference 5). (The case for dynamic traversable wormholes has
