AAWSAP DIRD: Traversable Wormholes, Stargates, and Negative Energy, April 6, 2010 — Department of War Research Paper
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…
Incident Overview
This Defense Intelligence Reference Document was written under the Advanced Aerospace Weapon System Applications Program (AAWSAP), the Defense Intelligence Agency contract run by Bigelow Aerospace Advanced Space Studies, and is dated April 6, 2010. It was declassified and published on September 18, 2026 as part of the sixth tranche of the Department of War’s Presidential Unsealing and Reporting System for UAP Encounters (PURSUE). The released copy carries redactions.
What the government released
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.
Primary-source excerpt
Drawn directly from the released document: “Cosmological inflation (Reference 3), cosmological particle production (Reference 3), classical scalar fields (Reference 3), the conformal anomaly (Reference 3), and gravitational vacuum polarization (Reference 14-17) are among many other examples that also violate the energy conditions. Since the laws of quantum field theory place no strong restrictions on negative energies and fluxes, then it might be possible to produce exotic phenomena such as faster-than-light travel (Reference 31-33), traversable wormholes (Reference 1-3), violations of the second law of thermodynamics (Reference 34, 35), and time machines (Reference 2, 3, 36).”
Related records
This paper was written under the contract set out in AAWSAP Statement of Objectives and AAWSAP Solicitation and Original Order, which defined what AAWSAP was asked to study. Read those first: they explain why a program framed around foreign aerospace threats commissioned papers on subjects this far from any known aircraft.
The case in this archive
This record is a primary source for the Advanced Aerospace Weapon System Applications Program, written up here at length from the contemporary record. The file and the case history are worth reading against each other: the document is narrower and more cautious than the account that grew up around it, which is usually the point.
Status of the case
A Defense Intelligence Reference Document is a literature review, and the government’s own summary asks that it be read as one: a reference and synthesis product rather than original research, released without any implication that the concepts it discusses have been validated. The paper collects and summarises published work. It does not report an observation, test a device, or offer evidence that anything it describes has been built, by the United States or anyone else. That caveat matters most for the papers on warp drives, wormholes, antigravity and negative energy, which survey theoretical proposals that remain speculative and in several cases depend on physics no experiment has shown to exist. AAWSAP was a Defense Intelligence Agency contract, awarded in 2008 to Bigelow Aerospace Advanced Space Studies in Las Vegas, to anticipate foreign aerospace threats decades ahead, and its 38 reference papers show what the program chose to spend its time on. The All-domain Anomaly Resolution Office has made no finding about this document, and none is implied by its release.
