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.

where t~ is the time a light signal is emitted from A to B, reflected at B back to A,
arriving at A at the time t~, and where it is assumed that the time t 8 at which the
reflection at B takes place is equal to the arithmetic average of t~ and t~. Only by
making this assumption does the velocity of light turn out always to be isotropic and
equal to c. From an absolute point of view, the following rather is true. If tR is the
absolute reflection time of the light signal at clock B, one has for the out and return
journeys of the light signal from A to B and back to A, if measured by an observer in an
absolute system at rest in the distinguished reference system:
y(tR -t~) = df c+ (70)
y(t; -tR) = d/c_ '
where d is the distance between both clocks, and where c+ and c_ are given by (67).
Adding the equations (70) one obtains
(71)
If an observer at rest with the clock wants to measure the distance from A to B, he can
measure the time it takes a light signal to go from A to B and back to A. If he assumes
that the velocity of the light is constant and isotropic in all inertial reference systems,
including the one he is in, moving together with A and B with the absolute velocity v,
the distance is
d' = (c I 2)(t! -t~) .
And because of (71)
(72)
d' = rd.Ji-( v2 I c2 )sin 2 f//. (73)
