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.

A Stargate in Times Square If a small wormhole (three or more dimensional) were to begin to appear or even bump into our local space, one would perceive this process as the occurrence of an unusually bright spot in the sky. Blue and red Doppler shifting of this bright spot would manifest when the intersection of the wormhole with our local space grows or recedes, respectively. III. The General Relativistic Definition of Exotic Matter and the Energy Conditions This section will consider the physics of the exotic matter that is required to build traversable wormholes. What exactly is "exotic" matter? In classical physics the energy density of all observed forms of matter (fields) is non-negative. What is exotic about the type of matter that must be used to generate traversable wormhole spacetime is that it must have negative energy density and/or negative flux (Reference 10). The energy density is "negative" in the sense that the configuration of matter fields one must deploy to generate and thread a traversable wormhole throat must have an energy density, pE (= pc2, where pis the rest-mass density), that is less than or equal to its pressures/tensions, P1 (Reference 1, 3). 4 In many cases, these equations of state are also known to possess an energy density that is algebraically negative, i.e., the energy density and flux are less than zero. It is on the basis of these conditions that 1 From this point forward in the text, all Latin indices (e.g., i, j, k = 1...3) that are affixed to physical quantities denote the usual 3-d1mens1onal space coordinates, x 1... x 3 , indicating the spatial components of vector or tensor quantities. 9 UNCLASSIFIED/ ,'FOA.
