Using space time for FTL communications

  1. Nov 30, 2015 #1
    I think we all know what an Alcubierre drive is, well this is similar in principle. Is it possible to conduct faster than light communication through the acceleration of a bubble of space time? is it even possible to do this without a ship, and just send it out as a warp bubble from a point like with a ship, but again no ship with no drive?

    No.

    The Alcubierre drive is believed to be impossible, requiring as it would some exotic matter that doesn't seem to exist. Other than that all I can see is that you have strung together some techno babble.

    Yes, IIRC, the exotic matter required for the Alcubierre drive to work, (or any similar principal for FTL travel), has to have a negative mass, or a negative density, something like that.
    It's one of those ideas that can be possible according to mathematics, but VERY implausible since it requires physics which is contrary to all observations.
