Defense Intelligence Reference Document Antigravity For Aerospace Applications

Defense Intelligence Agency · 44 pages · text from the file's own layer

This Defense Intelligence Reference Document (DIA-08-1003-018), dated 30 March 2010, was produced by the Defense Intelligence Agency as part of its FY 2009 Advanced Aerospace Weapon System Applications (AAWSA) Program. It reviews theoretical approaches to antigravity for aerospace propulsion, drawing on Newtonian physics, general relativity, cosmological dark energy and quantum vacuum effects. The report notes that no current technology can actively control gravity and that many concepts are far from practicable engineering.

m/kg), 1 N is the total number of turns of pipe wound around the torus, 'Pis the time
rate-of-change of the mass current flowing through the pipe, r is the radius of one of
the loops of pipe, R1 is the radius of the torus, and c is the speed of light (3 x 108 m/s)
(Reference 14). One should note the striking similarity between Equations (4) and (5)
for the dipole electric and dipole gravitational fields.

Using Equation (5), Forward (Reference 13,14) showed that there would be a need to
accelerate matter with the density of a dwarf star through pipes as wide as a football
field wound around a torus with kilometer dimensions in order to produce an antigravity
field (at the center of the torus) of G"' 10 10a.,n·, where a.,,c is the acceleration of the
(dwarf star density) matter through the pipes. The tiny factor 10-10 is composed of the
even smaller 110, which is the reason why very large systems are required to obtain
even a measurable amount of acceleration. To counteract the Earth's gravitational field
of 1-i requires an antigravity field of 1-i (vectored upward), and thus the dwarf star
density material within the pipes must achieve aac, = 10 11 m/s2 in order to accomplish
this effect.
Forward (Reference 5) also identified a configuration comprised of a rotating torus of
dense matter that turns inside-out like a smoke ring as another type of dipole
gravitational field generator. As shown in Figure 3, an inside-out turning ring of very
dense mass (M) will create an upward force (of acceleration a) in the direction of the
(constant) mass motion (Mv, vis the mass velocity). This is also a feature of the
