This Defense Intelligence Reference Document, dated 29 March 2010 and prepared by the Defense Intelligence Agency, is one of a series of advanced technology reports produced in FY 2009 under the Advanced Aerospace Weapon System Applications (AAWSA) Program. It uses a metric tensor approach from general relativity to catalog the physical effects of engineering spacetime, such as altered time, mass, light speed and antigravity. It concludes that such concepts, including warp drives, are consistent with physics, but that the energy requirements remain daunting.
