This Defense Intelligence Reference Document (DIA-08-1004-004), dated 6 April 2010, was produced by the Defense Intelligence Agency under its Advanced Aerospace Weapon System Applications (AAWSA) Program. It is one of a series of advanced technology reports from FY 2009. It reviews the general relativity physics of traversable wormholes and flat-faced "stargate" solutions for faster-than-light travel. It also covers the exotic negative energy these would need, proposed lab methods for generating it such as the Casimir effect and squeezed vacuum, and the constraints involved.

(Reference 50) experimentally demonstrated the very first simple, scalable squeezed vacuum source in the laboratory that consisted of a continuous-wave diode laser and an atomic rubidium vapor cell. The experimental tools one needs to begin exploring the generation of negative energy for the purpose of creating traversable wormholes are just now becoming available. 3. Gravitationally Squeezed Electromagnetic ZPF A natural source of negative energy comes from the effect that gravitational fields (of astronomical bodies) in space have upon the surrounding quantum vacuum. For example, the gravitational field of the Earth produces a zone of negative energy around it by dragging some of the virtual quanta (a.k.a. vacuum ZPF) downward. This concept was initially developed in the 1970s as a byproduct of studies on quantum field theory in curved space (Reference 25). However, Hochberg and Kephart (Reference 21) derived an important application of this concept to the problem of creating and stabilizing traversable wormholes. They showed that one can utilize the negative energy densities, which arise from distortion of the vacuum ZPF due to the interaction with a prescribed gravitational background, for providing a violation of the energy conditions. The squeezed quantum states of quantum optics provide a natural form of matter having negative energy density. The analysis, via quantum optics, showed that gravitation itself provides the mechanism for generating the squeezed vacuum states needed to support stable traversable wormholes. The production of negative energy densities via a squeezed vacuum is a necessary and unavoidable consequence of the interaction or coupling between ordinary matter and gravity, and this defines what is meant by gravitationally squeezed vacuum states. The magnitude of the gravitational squeezing of the vacuum can be estimated from the quantum optics squeezing condition for given transverse momentum and (equivalent) energy eigenvalues, j, of two electromagnetic ZPF field modes, such that this condition is subject toj ➔ 0, and it is defined as (Reference 21): ( 6) where il. is the ZPF mode wavelength, r is the radial distance from the center of the astronomical body in question, Ro is the radius of the Earth (6.378 x 106 m), Mo is the mass of the Earth (5.972 x 1024 kg), Mis the mass of the astronomical body, and r.,· is the Schwarzschild radius of the astronomical body. 8 Note that r., is only a convenient radial distance parameter for any object under examination and so there is no black hole collapse involved in this analysis. Any radial distance from the body in question can be chosen to perform this analysis, but using r_,. makes the equation simpler in form. Also note that Equation (6) contains an extra factor of two (compared to the j derived in Reference 21) in order to account for the photon spin. The squeezing condition plus Equation (6) simply states that substantial gravitational squeezing of the vacuum occurs for those ZPF field modes with /, 2: 8m·s of the mass in question (whose 8 r, = 2GMk2 . According to general relativity theory, this is the critical radius at which a spherically symmetric massive body becomes a black hole, i.e., at which light is unable to escape from the body's surface. 16 UNCLASSIFIED/ ,'P81l 8PPI@Itllt tt.!I!! 8HLY
