Comment on Some Emerging Possibilities For Space PropulsionparentComments−mrfusion12yThanks! Could you explain a bit more about how Alcubierre can't be used to send information?Wouldn't a spaceship traveling FTL be able to carry information?−Steuard12yYou know what? I take that back. At some point, I'd had the impression that Alcubierre's solution required a fixed velocity (so you couldn't start or stop the spaceship), but evidently that's not the case. It gets to be problematic after all! :)−ethbro12yI believe his point was "only if they can stop traveling at FTL".

Wouldn't a spaceship traveling FTL be able to carry information?
