[quote name='darthbudge']OK, I happened to watch Donnie Darko yesterday and started reading up on theories about the time traveling, which also happened to lead me to some ideas with Lost.
Please bear with me, because this will probably be hard to understand, anyone familiar with the time travel theory in Donnie Darko will probably understand it better though.
We know that the Oceanic Six leaving, and Ben moving that wheel caused the time loop to happen. When this happened, two distinct universes were created. One would be the primary universe (PU), which is inhabited by everyone off of the island. The second universe, the tangent universe (TU), is inhabited by everyone on the island.
Because they left the island, this TU was created and it has since been looping over and over again, whilst jumping through time. John, (maybe Ben as well) who stayed on the island is the key to stopping this time loop. He has to convince the Oceanic Six through any means to come back to the island and rectify this error in time, stopping the time loop and closing the TU, merging it back with the PU and everything would continue as normal in life.
This would also back up why outside of the island, 3 years have passed, but on the island it has only been a few days. Because basically, they, everyone in the TU, are repeating the same days over and over again, just in different time periods.
Also, it supports Daniel's "You Can't Change Anything" theory, because simply they are repeating the same thing over and over again. They are not changing reality, the PU, but instead the TU which is only in existence to get John and possibly Ben to bring back everyone to the island. Once the Oceanic Six returns to the island, and the TU is closed, everything that they changed to make that happen will simply go away.
While this is a fairly rough theory, I do think explains it fairly well. Since I know the people behind Lost are big Sci-Fi fans, no doubt some of them would be familiar with this line of time travel theory, and maybe they stole some of it.[/QUOTE]
i think youre looking too much into it. i think that 3 years have passed off the island becuase, 3 years have passed off the island. the people on the island are still in 2005, but off the island its been 3 years and its 2008/9. i suspect that over the next season or so 3 years wll pass on the island and when they finally get back together itll be 2009.
as for not being able to change the past, i think they are just using
david lewis' theory of compossibility. basically, you cant change the past because the past has already happened, if you try to, something will stop you. (the exception being the daniel/desmond relationship)
the thing about time travel is, as far as we know its not real, so you cant go around mixing ficiontal. what works in donnie darko time travel doesnt work in lost time travel, but maybe itll work in back to the future time travel, but it wont work in terminator or star trek time travel.
edit: uh oh, 9pm eastern, i wont be back in this thread for about 4 hours.
