Reactionless Thrusters for real???

[Humabout]

If this turns out to even be workable, it still isn't reactionless. The reaction mass merely exists at all points in the universe already, so you don't have to carry a fuel tank with you. Conveniently, the exhaust self-annihilates, too, so you aren't irradiating everything behind you, either. NASA is still poking this idea, but it has plenty of skeptics, too. It does make a cool basis for a constant acceleration drive, though! Easily as workable as any other scifi thruster for sure. And you get to use "force field", "quantum vacuum", and "virtual particles" properly in your technobabble explaination!
