This theory was sent in by our friend Hammer.
Valenzetti came up with a formula that predicts the end of the world. The numbers are the factors. What if DHARMA or anyone for that matter messed something up by changing something in the past?
Valenzetti’s equation found the resulting ‘D Day’ so to speak. DHARMA used the island to try to find a way to change one of the factors to ’save’ the world, but was stopped by the purge. Now, Ms. Hawking has found the island and now knows that they have 70 hours until the end of world. In effect, Ben’s group is trying to change a number to ’save us all’.
Is Ms. Hawking’s scribblings actually Valenzetti’s equation?
I couldn’t wrap my head around why the world (yes I am assuming that Ms. Hawking means the world and not just her people) is in trouble if the group doesn’t get back to the island. I mean to ask, “What is the REAL reason why they have to get back?” Yes to save the world, but WHY? What does it un-change or better yet change? So I started pondering recurring themes. And BANG, the numbers. They told us about them early on for a reason.
I am thinking that the Swan’s caretakers really were saving the world, then Desmond turned the key and we had the purple sky event with a huge discharge, which set off the chain of events that has us where we are today, trying to fix everything and save the world.
