AAWSAP DIRD, Negative Mass Propulsion, January 2011

This Defense Intelligence Reference Document, DIA-08-1101-023, is dated 3 January 2011. It was prepared by the Defense Intelligence Agency's Defense Warning Office as one of a series of advanced technology reports produced in FY 2010 under the Advanced Aerospace Weapon System Applications program. It covers theories of negative mass, including Bondi's mass dipole, Zitterbewegung and a Planck aether hypothesis. It proposes tunneling through the Moon with thermonuclear shaped charges to search for trapped negative matter. It concludes that such propulsion may perhaps be possible through an ultra-light form of matter but remains speculative.

From the source:Release of 2026-09-18 Incident: 1/3/11, 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 whether negative mass could exist in a physically meaningful way and whether it could someday reduce the energy cost of spaceflight. The report reviews the unusual dynamics that would follow if positive and negative mass could interact, including self-accelerating mass pairs and matter with very low or nearly zero effective inertia, and treats such ideas as at least formally compatible with certain extensions of gravitational theory. It then considers two broad paths toward practical use: creating or separating negative mass through extreme fields or particle energies, and locating naturally separated negative matter in deep gravitational wells such as galactic centers or possibly the Moon. However, the document also concludes that the first path is effectively beyond technical reach and treats the second as highly uncertain, resting on a long chain of unverified assumptions about the existence, separability, and macroscopic behavior of negative mass. Overall, this DIRD is a far-reaching theoretical exploration of an exotic propulsion concept whose practical application depends on premises that remain unestablished in consensus physics.

density of the rocks. For Pmax =5 x 1010 dyn/cm2 one finds T =4 x 103 K . Both the
pressure and the temperature are technically manageable, the pressure with layers of
shattered rocks around a tunnel passing through the center of the moon, and the
temperature with some cooling. Seismic measurements suggest that the center of the
moon is made up of hot rocks.
If appreciable amounts of negative matter have accumulated over billions of years in
the center of the moon, it is more likely that this matter is in the form of ultra-light
matter, perhaps by an order of magnitude lighter tha n ordinary matter. There are
indications that a Swedish research group has found evidence for the existence of an
ultra-dense phase of deuterium, about more than 100,000 times more dense than
water [16]. Suppose that in the center of the moon the accumulation of negative
matter has led to a form of matter wh ich is 100,000 times lighter than steel, but still
has the strength of steel. This would not lead to a negative- positive mass self-chasing
mass dipole as envisioned by Forward [13], but to something very important for space
flight, because it would dramatically reduce the energy requirements to accelerate a
space craft made from such ultra-light material.
The question as to whether there is such an unusual substance in the center of the
moon can probably be answered by seismic wave tomography, obtained by nuclear
explosions set off on the surface of the moon.

The cohesive energy of rocks is of the order &,. ,;:::, 1010 erg/cm3 . Therefore, the explosive
yield needed to shatter a spherical volume of rad ius r is

The energy released in a kiloton nuclear explosion is E,;:::, 4xl019 erg. With this energy,
the radius of the crushed rocks would be r,;:::, 103 cm (= 10 m), and with a 10 kiloton
explosion it would be twice as large.
