This Defense Intelligence Reference Document from the Defense Intelligence Agency is dated 2 April 2010 and was produced under the Advanced Aerospace Weapon System Applications (AAWSA) Program. It is one of a series of advanced technology reports from FY 2009. It reviews general relativistic warp drives, the cosmological constant, Casimir energy and extra space dimensions. It proposes that dark energy may come from higher dimensions and that controlling those dimensions could one day make a warp drive possible.
UNCLASSIFIED/ ,'F8R 8FFl01fok 1,16& 8Plk¥ I - Figure 7. A Combination of Phenomenologically Viable Fields Generates a Stable Minimum of the Vacuum Energy Density at a Fixed Higher Dimensional Radius. This stable minimum, located at a positive energy, indicates a stable deSitter type spacetirne and reflects a realistic dark energy model. Note in this plot that the radius of the extra dimensions 1s shown on the x-axis, and the energy density on the y-axis (normalized units are used). \'\' ------ - :\111tic;i) !lllllllll\llll / '.'\"atural llllllllllUlll :\111fi~·.1l !!l11l11lllll!l Figure 8. False Vacuum Minima are Created Around a Spacecraft. The different minima create an asymmetric dark energy pressure on 3-space which generates the warp bubble. In this plot the x-axis represents the radius of the extra dimension, and the y-axis represents the energy density (normalized units are used). The key to creating a warp drive is to create a false vacuum minimum, i.e., to modify the vacuum spectrum and inject some field which creates a deSitter minimum at the rear of the craft and an anti-deSitter minimum at the front of the craft. What this requires is a technology that would allow us to artificially manipulate the field content illustrated in Figure 7, shifting the location of the minimum. In this basic representation, the spacecraft would sit in a stable region of space corresponding to the natural minimum of the extra dimension. At the front and rear of the craft, regions of 19 UNCLASSIFIED//F8ft 8FFIOIAI! l!lfili 8PJl!Y
