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.

UNCLASSIFIED/ 'FOR OFFICIO I 1!55 0111 Y • According to Maxwellian electrodynamics, an electric current flowing through a wire that is wrapped around a torus (or ring) causes a magnetic field to form inside the torus. If the current (I) in the wire increases with time, then the magnetic field B inside the torus also increases with time. This time-varying magnetic field in turn creates a dipole electric field E, as shown in Figure 1. The magnitude of the electric field at the center of the torus is given by: (4) where μ0 is the vacuum electromagnetic permeability constant (4rc x 10 7 H/m), N is the total number of turns of wire wound around the torus, i is the time rate-of-change of the electric current flowing through the wire, r is the radius of one of the loops of wire, and R1 is the radius of the torus. Figure 1. Dipole Electric Field Generator (Reference 14) In a similar fashion, Forward's antigravity device is a dipole gravitational field generator. As shown in Figure 2, a mass flow T through a pipe wound around a torus induces a Lense-Thirring field P to form inside the torus. If the mass flow is accelerated, then the P-field increases with time, and thus a dipole gravitational field G is created. The magnitude of the anti-gravitational field at the center of the torus is given by: 5 G~ Y\oNr'fl< 4nR' ' UNCLASSIFIED/ ,<6OAt Qp;p;JQl11J.k laUiF SU•L•t ( 5)
