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.

One believes that an energy field called the Higgs boson permeates spacetime and that the interaction of matter with this field is what is responsible for particles acquiring mass. One believes that an exotic ubiquitous energy source, unimaginatively named dark energy, is responsible for the current accelerated expansion of the universe based on observation of supernova in galaxies billions of light years from Earth. One also believes that the universe may not consist of the three spatial dimension of length, breadth, width, and one of time, but that, in fact, there may be as many as seven additional compactified dimensions assuming the topology of a Calabi-Yau manifold, and that the fundamental building blocks of the universe are, in fact, extended string-like entities. Modern physics is full of many exciting and marvelously imaginative creations. Because one understands these curiosities, one could potentially harness these elements of nature for one's own technological ends. This is by no means a certainty, but if we may make predictions based on the innovative history of scientific pioneers of the past, then it seems entirely possible that the creative minds of the future may indeed find ways to accomplish what, to us, may seem like magic. 1 Alcubierre, M., "The warp drive: hyper-fast travel within general relativity," Classical and Quantum Gravity, vol. 11, 1994, pp. L73-L77. 2 Obousy, Rand Cleaver, G., "Warp drive: A new approach," J.
