great possible explaination...
Ok, I'm spitballing a bit now, but if you haven't seen all of series 3 of LOST and you don't want any potential spoilers, stop reading NOW!
Right... I have a few theories about LOST that I feel like discussing with anyone else who loves the series.
Firstly, watch this video - it's a clip that's been released from series 4. A new orientation video for a station called "The Orchid" - http://www.youtube.com/watch?v=4bTvAUVPyLI
There's a LOT you can take from it.
Firstly, what is the freeze frame of a building? Where is it?
Next, there's a flicker where you see, "God loves you as He loved Jacob". Note 'loved', past tense. Interesting.
Now, the really interesting bits. You see a rabbit appear from nowhere with 15 on it, the same number as the rabbit in the guy's hands. My theories start from here, and that theory is that they're experimenting with time travel. He speaks of the Casimir effect that is generated at the station. The Casimir effect is basically about the way energy is produced when two items with certain properties change when they get too close. And from the wiki page on it - http://en.wikipedia.org/wiki/Casimir_effect
- it says: "Exotic matter with negative energy density is required to stabilize a wormhole. Morris, Thorne and Yurtsever pointed out that the quantum mechanics of the Casimir effect can be used to produce a locally mass-negative region of space-time, and suggested that negative effect could be used to stabilize a wormhole to allow faster than light travel."
Basically it's feasibly allows the creation of a portal in space time where objects can travel faster than light, meaning they appear places before they've happened, aka time travel.
This could explain why the rabbits were made to be kept apart.
This would also explain a lot of other things that were brought up in the 3 series.
The plane was found at the bottom of the ocean with all the passengers dead on-board. I think that the magnet in the first hatch that got blown up at the end of series 2 was preventing something (I don't know quite what), but when Desmond didn't get back in time and it failed (ultimately crashing the plane) a rift was created. This meant that the plane crashed BOTH in the ocean (real time) and on the island (another period of time). I think it's important to note that we know the island is / was volcanic from what the school teacher said in series 3, so what if the island wasn't there in real time, but was created by an eruption in this "new" time. This is also explain why Juliet had to take all the sedative when she travelled to the island - because it wasn't a "normal" journey, it involved passing through time, or possibly dimensions.
Also, Desmond sees the future. Maybe he doesn't. Maybe he has memories of doing something before. When he has the flashback to being in London when the hatch explodes, I think he's actually sent back in time. Quite how he gets back again, I'm unsure, but I think that the fact that he arrives woken up naked in the jungle is because only he was able to pass through some kind of portal.
At the end of series 3, it appears that they've gotten off the island as Jack and Kate meet up. I think that the person that Jack discovers is dead in the clipping is Ben as he would have been taken off the island when everyone was collected. As John said at the funeral, he was neither family nor a friend, and it would make sense why Kate said "why would I go" when questioned about it. Maybe this isn't a flash of the future though, but a previous past or something like that.
Saving the best concept until last, and my MAJOR thought, is about Jacob. When Ben introduces Locke to him, he tells him that "Jacob feels the same way about technology as you do". At the end of series 3, when Jack is radioing for help, Locke walks off. I think that if they DID leave the island, Locke stayed behind, and that Jacob and Locke, are in fact the same person....
