It's an abuse of General Relativity, rather than Special Relativity, but it ought to carry the same problems with causality. if you can get from here to Alpha Centauri in a month, and back in another month, you're doing hideous things to causality. Saying that the Alcubierre Metric is a solution to the field equations for GR isn't really any different than saying tachyons are a solution to SR. The only difference is that we've shown tachyonic fields must collapse, and nobody's quite sure what negative mass needed by a warp drive actually means (or if there's any physically meaningful transition between our mostly-flat spacetime geometry and the spacetime geometry of the Alcubierre Metric). You should have absolutely no expectation of this research ever leading to a warp drive.
