'Impossible' engine may actually work, NASA engineers suggest
Washington (UPI) Aug 4, 2013 - The laws of classical physics require a rocket's thrusters to push against something, creating acceleration by expelling matter (burned fuel) in the opposite direction. Thus, so-called space drives - engines that don't require fuel, but use alternative mechanisms to thwart the laws of physics and create thrust out of thin air (really thin space air) - have always been considered "impo ... more
