Is FTL in our Future? (part 3)


If you have not heard about NASA’s EM drive, it is the current center of speculation regarding the possibility of FTL. An EM drive, or Electromagnetic drive, is a new method of powering a rocket through space. Traditionally, past methods of powering rockets have been designed to use something as a propellant to push the rocket through space, but the EM drive eliminates that altogether. The basis of its design involves bouncing microwaves around inside an enclosed chamber, and its success apparently violates Newtons 3rd Law: everything must have an equal and opposite reaction. Yet the EM drive does not behave according to the law, which would involve it propelling something the opposite direction. Amazingly, the EM drive produces light as exhaust. Many are saying that the EM drive could get astronauts to our moon in an hour, and to Mars in a month, which is three times faster than the speeds we're currently capable of. But you're probably saying, a month is still a long time to Mars, so that certainly doesn't sound even close to FTL speeds! The key to all this, though, is something discovered with the EM drive...
