Hey... I always interpreted that graphic as a mine-layer vessel (explaining why Lore's borg had one) hence it would be the borg ship laying the mine rather then the mine itself.
removed info Edit
I removed the following bginfo:
- Curiously, the shape of the mines resembled that of the rogue Borg ship from TNG: "Descent" and "Descent, Part II". The size of the mine could be considerably smaller, however; taking the size of a nanoprobe to be approximately equal to the size of a red blood cell, 50 trillion nanoprobes take up considerably less than 1m3. It is often speculated that therefore, the display is actually of the minelayer.
for being original research, and speculated by who? -Angry Future Romulan 16:26, November 17, 2010 (UTC)
