Travel through different vacuum phase

[scasca]

It could be possible for a driven vacuum bubble (like an Alcubierre drive,assuming that it could be possible to realize ) to travel not only many order of magnitude faster than light but even trough different vacuum phase ? like for example region of false vacuum ?

No, the boundaries of regions with different vacuum states move at close to, but still slower than, the speed of light.
