Moreover, why is something moving this slowly not more widely known about? And patrolled? I would think both science vessels and very likely military cruisers belonging to dozens of governments would be tailing this thing through space in the interests of study and tactical exploitation. Those pesky Romulans would just love themselves some Nexus torpedoes Yet no one cares. This ridiculously destructive monster just wanders through space, very close to inhabited planets, with no one to even warn potential victims. *shrugs*
The Nexus, I always thought only took in Organic Matter. That's why there are horses, trees, planets... Yet it destroys ships.
Honestly, I find the first half of Generations decent enough. Just the second half is plain terrible.
