Alcubierre warp drive as time machine.

  1. Nov 15, 2012 #1

    I heard it's possible to use an "Alcubierre warp drive" as a time machine, if they existed. But how, precisely, would that work?

    It would normally be called a "causality violation".
    In general, travelling faster than light suggests the possibility of setting one up.

    Alcubierre drives would certainly offer the opportunity to experiment in time travel ... though I would anticipate that, should the Universe allow FTL under some special conditions, those same conditions would prevent such a violation somehow.
