Star Trek: 10 Times Voyager Could Have Got Home
9. Eye Of The Needle - Temporal Displacement
This option is tinged with a bit of tragedy. Yes, the crew could have gotten home to the Alpha Quadrant, but only by either causing huge changes in the timeline or hiding away in private for twenty years.
The micro-wormhole that Kim discovers not only connects them with Telek R'Mor, of the Romulan Astrophysical Academy, but also with the year 2351. Once Janeway learns of this, she is crushed, as until that moment the crew had been hopeful they could simply beam through the wormhole and get home the quick way - even though it would mean abandoning the ship, and the EMH with it.
The unfortunate but inevitable decision to remain in the Delta Quadrant is made slightly more bearable by the promise that R'Mor will transfer messages to their loved ones, once his time catches up with theirs. Tuvok, ever the glass-half-full Vulcan, then informs the captain that R'Mor dies in 2367 - four years before Voyager left for the Badlands.
