Plot hole: To escape the 'event horizon', a rupture in it is widened to 120 meters (which allows 2 meters clearance on each side of the ship). Soon after, the rupture has shrunk to 110 meters wide, and Janeway decides to 'punch through' anyway. The ship does so with little difficulty, but the whole issue seems pointless since the rupture was far larger 'vertically' than 'horizontally' (relative to the view from the ship), so tipping the ship on its side would have allowed plenty of clearance to slip right through.

Deliberate mistake: When the Doctor begins to "fade" in the transporter room his mobile emitter fades with him. Since it's made of solid matter and is not a hologram, this shouldn't be possible.
The Doctor: Watch your tongue... Or I'll remove it.
Trivia: Rain Robinson has a model of a DY-100 on the window sill in her office. In 1996 (also the year this episode is set), Kahn left Earth in the SS Botany Bay, a DY-100 class starship.

Question: Before the future Admiral Janeway time-travels to cut time off Voyager's return trip to Earth, the time where she came from was stated as "10 years after a 23 year voyage across the galaxy", which would be 2404. But if the Star Trek reboot is canon, then the alternate reality is created in 2387. Would that affect anything?
Answer: It's been established that the reboot doesn't affect anything in the original timelines of any prior series. The alternate timeline of the new films does not change anything that came before.
