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.
UNCLASSIFIED//FIHl 8FFHil.t.k Wfili IH.k\f • Gravitationally squeezed vacuum electromagnetic zero-point fluctuations (Reference 21). • Casimir effect, i.e., the Casimir vacuum in flat, curved, and topological spaces (Reference 22-28). • Other quantum fields/states/effects. In general, the local energy density in quantum field theory can be negative due to quantum coherence effects (Reference 12). Other examples that have been studied are Dirac field states: the superposition of two single particle electron states and the superposition of two multi-electron- positron states (Reference 29, 30). In the former (latter), the energy densities can be negative when two single (multi-) particle states have the same number of electrons (electrons and positrons) or when one state has one more electron (electron-positron pair) than the other. Cosmological inflation (Reference 3), cosmological particle production (Reference 3), classical scalar fields (Reference 3), the conformal anomaly (Reference 3), and gravitational vacuum polarization (Reference 14-17) are among many other examples that also violate the energy conditions. Since the laws of quantum field theory place no strong restrictions on negative energies and fluxes, then it might be possible to produce exotic phenomena such as faster-than-light travel (Reference 31-33), traversable wormholes (Reference 1-3), violations of the second law of thermodynamics (Reference 34, 35), and time machines (Reference 2, 3, 36). There are several other exotic phenomena made possible by the effects of negative energy, but they lie outside the scope of the present study. This section will review the previously listed items 1 thru 4 and examine their applicability and technical maturity. Dirac field states are currently under study by investigators. Also, the issue of capturing and storing negative energy is not considered in what follows because free-space negative energy sources appear to be a more desirable option for inducing traversable wormholes than stored negative energy, and because there is very little technical literature that addresses how to capture and store negative energy (see, e.g., Reference 10). The issue of capturing and storing negative energy will be left for future investigations. B. GENERATING NEGATIVE ENERGY IN THE LAB 1. Static Radial Electric & Magnetic Fields It is beyond the scope of this study to include all the technical configurations by which one can generate static, radially-dependent electric or magnetic fields. Suffice it to say that ultrahigh-intensity tabletop lasers have been used to generate extreme electric and magnetic field strengths in the lab. Ultrahigh-intensity lasers use the chirped-pulse amplification (CPA) technique to boost the total output beam power. All laser systems simply repackage energy as a coherent package of optical power, but CPA lasers repackage the laser pulse itself during the amplification process. In typical high-power short-pulse laser systems, it is the peak intensity, not the energy or the fluence, which causes pulse distortion or laser damage. However, the CPA laser dissects a laser pulse according to its frequency components, and reorders it into a time-stretched lower- peak-intensity pulse of the same energy (Reference 37-39). This benign pulse can then be amplified safely to high energy, and then only afterwards reconstituted as a very short pulse of enormous peak power - a pulse which could never itself have passed safely through the laser system. Made more tractable in this way, the pulse can be 11 UNCLASSIFIED/ ,<FQA QFFifiI1t1k HSI! 8HLY
