When Locke says move the island maybe he does not mean physically, or through space, but through time. Locke will tell Jack he is going to move the island 10 years (random guess, could be more or less) into the future to avoid Widmore and protect the island. Jack of course think's Locke is mad but with Ben's helps he is assured safe passage off the island and that they must return safely in 10 years. They [the Oceanic 6] get off the island in the chopper, and of course Jack thinks Locke is mad -- but they can't rescuse anybody else because the island is gone. They have to fabricate a story to avoid anybody trying to find this island which no longer exists in this time-line and they have to get over the fact that these people will at least not been seen for 10 years.
Jack, a man of science, ignores all of this 'nonsense' for some time, despite being reminded by the island that he must return alongside Hurley by the likes of his father and Charlie. Eventually he decides they have to get back to the island as the date is approaching that allows their safe return. As was seen in the Season 3 finale, he desperately tries. "We have to get back Kate" -- but Kate still thinks he's crazy and that the island and everybody on it is gone. Jack tries to find Ben thinking that he is the only guy that knows how to get back, but Ben is the guy in the coffin. Will future Jack, Kate, Hurley, Aaron, Jin and Sayid get back to the island upon it's return? Is Ben really dead? How will this time difference effect everything, and what will the flashbacks/fowards be next season? Flashbacks to the time off the island leading to The Oceanic Six's return? Or is this all even far too weird for Lost? I think things like the Black Rock and the 4-toed statue may also ! help to show that the island has been moved through various stages of time before in the past.
