Ok for all LOST fans or those who have watched LOST up to a certain point then decided to give up as it was too confusing (this is for the former since it is a little.. deep).. some brilliant chap came up with this fantastic theory that sounds so convincing and accurate it's as if the LOST writers wrote it themselves!!
The link is here:

it's a pretty lengthy read, probably take you 10-20 minutes to absorb the whole thing as it is a little complicated (hey waddya expect, a theory to explain LOST has to be a little deep)
It's very interesting though, and makes total sense, so i would high encourage you to read it if you have the time. I'll just highlight some key points, but they will be far from sufficient to explaining anything so you have to read the article!

The whole concept that the guy came up with was - time travel. The Dharma initiative came up with this time machine thing that allowed time travel. The article totally explains why this is so and gives alot of supporting evidence from the show that explains this theory.
Now it is a little more complicated than it sounds.. you need to read the page to understand it's hard to explain.
Anyway here's some rules of the time travel:
1) When someone enters the time machine, they can only go back in time – and only to a time where the machine was currently running.
2) When you go back in time, you do not de-age. For example, if you are 50, and go back 10 years in time, you do NOT have your 40-year-old body. HOWEVER, while you are re-living 10 years of your life, you body will not age until you catch up with the time in which you entered the time machine.
3) When you go back in time, you will still have your current hair style, tattoos, and memory. However, say you were paralyzed; fate would need to do some course correction to make sure that you are still able to play your past role in life. Thus, time travel can TEMPORARILY cure any physical ailments you may have had prior to entering the time machine.
However, fate will still find a way to paralyze you once you catch up with the current time. Say the first time you were paralyzed, it was because you were pushed out of a window. Because “the universe has a funny way of course correcting,” you may get hit by a car the second time around.
4)When you go back in time, you can only “change” things that don’t have an impact on your destiny. In other words, if you went to church on a specific date in the past, and then went back in time, you wouldn’t necessarily go to church in your new timeline. However, if you changed a belief as a result of going to church the first time around, “fate would find a way to influence you into that belief.” Perhaps you would have a near death experience, or maybe a mysterious person would greet you in a jewelry store and tell you that you need to change your beliefs… or, maybe fate would just kill you since it couldn’t find a way to change your belief.
5) If you go back in time and die, you are not “totally” dead because there has already been a variation of the universe where you were alive in the future. Thus, you become “half dead” until time catches back up. In other words, your presence may be known to some people but not others. Your presence would only be known when you are required to make an impact to fate.
6)If you have never had a child, you cannot go back in time and give birth. Fate does not allow for a new entity to exist in a past where it originally did not exist. Thus fate would either have to kill the mother, the baby, or both in order to course correct. UNLESS, fate decides to use the baby or mother to “replace” someone else in the timeline.
7) Basically, the “rules of the time machine” are not governed by any physical definitions of time travel. The “rules,” if you will, are governed by how FATE decides to preserve the timeline. Thus, if you are required to do something profound in a future timeline, fate will find any way possible to preserve the timeline – we’ve seen ghosts and smoke monsters in LOST. So according to the show’s definition of time travel, fate “does have a funny way of course correcting.”

that's the rough gist of it. Read the main article for how this links to the show and how many events are explained. The guy is good man!
