This Defense Intelligence Reference Document from the Defense Intelligence Agency is dated 3 January 2011. It was produced under the Advanced Aerospace Weapon System Applications (AAWSA) Program as part of a series of advanced technology reports. The report asks whether negative mass exists and whether it could be used for propulsion. It concludes that one route might be an ultra-light form of matter that could have gathered at the Moon's center. Reaching it would take a tunnel dug with thermonuclear shape charges.

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(1R-1'.,)=d/c y(t,;-tR)=d/c (70) where dis 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 (72) And because of (71) d' = rc1.J1-(v 2 /c 2 )sin 2 If/.
