I also have a few questions regarding first contact...when the movie starts, the enterprise is out near the Romulan NZ scanning for whatever. From what I can recall, the RNZ is pretty far from earth, yet they're able to warp back to earth so quickly to join the battle against the borg. How is that possible that they can get there so quickly? Also why not stop first contact by destroying the Vulcan ships? Why even try to stop first contact? In that period in earth history, aren't the borg strong enough just to simply go down to earth where the majors powers are and just assimilate them? I love first contact, but that's always bugged me.
