Five SF Stories That Embrace the Scientifically Improbable Reactionless Drive
Tales of the Flying Mountains cover art by Bob Layzell (Tor Books, 1984) Recently, physicists around the world were astounded to learn that painstaking testing of the visionary EmDrive revealed that the device produces no discernable thrust. By “astounded,” I mean “not astounded” and by “visionary,” I mean “almost certainly nonsensical from word one.” A cynical physicist might say the EmDrive produces thrust by violating conservation of momentum. This is unfair, because the EmDrive does not produce thrust at all. One can understand the attraction of a reactionless drive. It co...
