Recall that space itself can expand faster than the speed of light (since no net information is being transferred by expanding empty space). Similarly, it may be possible to travel faster than the speed of light by shrinking space faster than the speed of light. In effect, when traveling to a nearby star, we may barely leave Earth at all; we would simply collapse the space in front of us and expand the space behind us. Instead of traveling to Alpha Centauri, the nearest star, we are bringing Alpha Centauri to us.
