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.

Comparing this result with (66), one sees that he would obtain the same distance d', if
he uses a contracted rod as a measuring stick, or Einsteins's constant light velocity
postulate. The velocity of light between A and B by using a rod to measure the distance
and the time it takes a light signal in going from A to B and back to A, of course, will
turn out to be equal to c, because according to (72)

Rather than using a reflected light signal to measure the distance d' , the observer at A
may try to measure the one-way velocity of light by first synchronizing the clock B with
A and then measure the time for a light signal to go from A to B. However, since this
synchronization procedure also uses reflected light signals, the result is the same. For
the velocity he finds

By subtracting the equations (70) one finds that
tR = fB + (rIC2) vd cos If/ , (76)
which shows that from an absolute point of view the "true" reflection time tR at clock B
is only then equa l to t8 , if v = 0. From an absolute point of view the propagation of
light is isotropic only in the distinguished reference system, but anisotropic in a
reference system in absolute motion against the distinguished reference system. This
anisotropy remains hidden due to the impossibility to measure the one-way velocity of
light. The impossibility is expressed in the Lorentz transformations themselves,
containing the scalar c2 rather than the vector c, through which an anisotropic light
propagation would have to be expressed.
