Hijacking a hyperspace traveller through neutrino twinning and particle pairing.
That's a nice thought. But what Bernie had come up with in that moment of distraction was the idea that his FTL drive could also be an awesome weapon, by simply producing a smaller version which could be programmed to coalesce at any known or relative coordinates.
In effect, it's a sub-space torpedo that re-appears inside the enemy's defensive perimeter, homing on a section of solid matter instead of trying to avoid it. Physics being what it is, the results would be ... unfortunate.
