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.

Finally, Ries et al. (Reference SO) experimentally demonstrated the very first simple,
scalable squeezed vacuum source in the laboratory t hat consisted of a continuous-wave
diode laser and an atom ic rubidium vapor cell. The experimenta l tools one needs to
beg in exploring the generation of negative energy for the purpose of creating
traversable worm holes are just now becoming available.
3. Gravitationally Squeezed Electromagnetic ZPF
A natural source of negative energy comes from th e effect that gravitational fields (of
astronomical bodies) in space have upon the surround ing quantum vacuum. For
example, the gravitational field of the Earth produces a zone of negative energy around
it by dragging some of the virtua l quanta (a.k.a. vacuum ZPF) downward. This concept
was initially developed in the 1970s as a byproduct of studies on quantum field theory
in curved space (Reference 25). However, Hochberg and Kephart (Reference 21)
derived an important application of th is concept to the problem of creating and
stabilizing traversable wormholes. They showed that one can utilize the negative energy
densities, which arise from distortion of the vacuum ZPF due to the interaction with a
prescribed gravitational background, for providing a violation of the energy conditions.
The squeezed quantum states of quantum optics provide a natural form of matter
having negative energy density.
The analysis, via quantum optics, showed that gravitation itself provides the
mechanism for generating the squeezed vacuum states needed to support stable
traversable wormholes. The production of negative energy densities via a squeezed
vacuum is a necessary and unavoidable consequence of the interaction or coupling
between ordinary matter and gravity, and this defines what is meant by gravitationally
squeezed vacuum states. The magnitude of the gravitational squeezing of the vacuum
can be estimated from the quantum optics squeezing condition for given transverse
momentum and (equivalent) energy eigenvalues, j, of two electromagnetic ZPF field
modes, such that this condition is subject toj ➔ 0, and it is defined as (Reference 21):

where ,l is the ZPF mode wavelength, r is the radial distance from the center of the
astronomical body in question, Ro is the radius of the Earth (6.378 x 106 m), Mo is the
mass of the Earth (5,972 x 1024 kg), Mis the mass of the astronomical body, and rs is
the Schwarzschild radius of the astronomical body. 8 Note that rs is only a convenient
radial distance parameter for any object under examination and so there is no black
hole collapse involved in this analysis. Any radial distance from the body in question
can be chosen to perform this analysis, but using rs makes the equation simpler in
form. Also note that Equation (6) contains an extra factor of two (compared to the j
derived in Reference 21) in order to account for the photon spin. The squeezing
condition plus Equation (6) simply states that substantial gravitational squeezing of the
vacuum occurs for those ZPF field modes with A~ Bnrs of the mass in question (whose
8 r, = 2GM/c2. According to general relativity theory, this is the critical radius at which a spherically symmetric
massive body becomes a black hole, i.e ., at which light is unable to escape from the body's surface.
