Losties will both die and live by AbsoluteTruth

Just a few things I have been thinking about lately in regards to how season 6 will go. Richard said that he saw the losties die. Jack and co. possibly blew jughead. This may have changed the future. I apologize for this touching on a lot of already theorized posts, I am trying to get more specific in this.

I do not think that the blast will kill the losties, as I am sure the show will tell us that the islands energy and the nuclear explosion negated each other. They will continue to live in the 70s, possibly under duress from Dharma for what they did. I am not sure what will happen after that, but something will happen (possibly the purge), that will kill them. I was also thinking perhaps Sawyer gets a dying Juliet out of the hole and brings her to the cave and they become Adam and Eve but thats probly more of a stretch than this whole theory.

Anyway, jughead going off did not change the losties future, but changed the future of a reality that the incident itself created. In that future, the button was not needed to be pressed, and flight 815 never crashed onto the island. I believe Jacob's touch will enable the losties of this reality to remember their time in the previous one. His touch was some kind of "reality constant".

Once those touched start to remember everything they begin to contact each other and eventually (hopefully really quickly) return to the island to reunite with Ben, Flocke, Sun and company.

They are dead, but they are also here.
