NASA Tests 'Impossible' Space Drive

@ 2014/08/03
NASA scientists have conducted tests on a new form of space propulsion called the Cannae Drive. It is radically different from any other yet devised form of propulsion as it uses no standard form of fuel and has the potential of shortening trips to Mars from months to just weeks. While the amount of thrust generated in these NASA's tests was lower than previous trials — between 30 and 50 micronewtons, way less than even the weight of an iPhone, as Nova points out — the fact that any thrust whatsoever is generated without an onboard source of fuel seems to violate the conservation of momentum, a bedrock in the laws of physics.
