It's an interesting idea, and ideas that are not impossible have a tendency to become practical. But there's a really big "but" in this one: Unless you can start traveling faster than light without accelerating your mass (or without having any mass) to the speed of light, it still takes an infinite amount of energy.
- rbanffy 4y agoThe interesting point of Alcubierre’s work was precisely that: it doesn’t accelerate the traveler - it compresses and expands regions of space ahead and behind the traveler so that they remain still within their inertial frame. Still should require a ridiculous amount of energy though, if at all possible.
