One character in Star Trek: Voyager took ten years to get home, instead of seven. After arriving in the Delta Quadrant, Captain Kathryn Janeway’s (Kate Mulgrew) crew estimated getting back to the Alpha Quadrant would take 75 years, even at maximum warp. That time was cut down considerably with technologies like the quantum slipstream drive, Borg transwarp conduits, and a telekinetic parting gift from Kes (Jennifer Lien) that shaved 9,500 light years off the trip’s original 70,000 light year distance. Ultimately, a future version of Admiral Janeway helped whittle the USS Voyager’s journey down to a mere seven years.
