The Downside of Warp Drives: Annihilating Whole Star Systems When You Arrive 235

MrSeb writes "The dream of faster-than-light travel has been on the mind of humanity for generations. Until recently, though, it was restricted to the realm of pure science fiction. Theoretical mechanisms for warp drives have been posited by science, some of which actually jive quite nicely with what we know of physics. Of course, that doesn't mean they're actually going to work, though. NASA researchers recently revisited the Alcubierre warp drive and concluded that its power requirements were not as impossible as once thought. However, a new analysis from the University of Sydney claims that using a warp drive of this design comes with a drawback. Specifically, it could cause cataclysmic explosions at your destination."

War By Remote Control, With Military Robots Set To Self Destruct 144

New submitter RougeFive writes "A new wave of Kamikaze unmanned military aircraft, ground robots and water vessels are being built to deliberately destroy themselves as they hit their targets. Since it now makes more economic sense to have them crash into enemy targets rather than engage them, and since direct impact needs only manned or automated navigation rather than the highly-trained skills of multiple operators, these UAVs could well become the de-facto method of engagement of the future."
