In no way do I suggest that this is some sort of grand unifying theory, but I've got a couple ideas about where some of this may be going.
First, a number of these ideas are based solely on the information found at these two sites:
This last page was apparently hidden on the Hanso Foundation site--just to bring those of you unfamiliar with it up to speed.
As we know the hatch was part of some experiment being conducted by the Hanso Foundation. It was the Dharma Initiative. I think that this project was the unification of the seven "official" projects that Hanso was working on:
The Hanso Life-Extension Project
The Hanso Foundation Electromagnetic Research Initiative
The Hanso Quest for Extra-Terrestrial Intelligence
The Hanso Mathematical Forecasting Initiative
The Hanso Cryogenics Development Imperative
The Hanso Juxtapositional Eugenics Development Institute
The Hanso Accelerated Remote Viewing Training Facility
and the end result was to be some sort of supersoldier, but this is just purely based on the fact that Hanso made his name as an arms dealer in the past. Why should we believe that he has actually changed his ways?
But that's not what's really important. Everything we've seen on the island that is strange, with the exception of the "security system" and the hatch; i.e., the Others, the polar bears, the black swarms, the sickness and even the numbers themselves are parts of the project that have escaped.
The Others were test subjects: probably in the eugenics experiments, and this is where we get our twins. Some escaped, maybe with the help of some rebellious researchers (who perhaps discovered the truth about the project that they were working on) sometime pre-filmstrip, and thus the security measures that Dharma temporarily put in place. But perhaps the ones who got out kept attacking the project trying to free the other subjects in other stations. They call themselves "Rabbits" as in test bunnies. Thus the website "bigspaceship1.com" up there. Listen to it. He's calling all rabbits (of the rebellion?) and giving them a secret message via numbers. The researchers eventually fled or were removed by the Hanso organization (or were killed), leaving the "rabbits" to the island, and the Dharma Initiative was abandoned. Maybe the rabbits released the individual experiments as a means of attacking the Hanso researchers: the polar bears (which are part of the cryogenics experiment), the swarms (which I think have something to do with the electromagnetic experiment, but don't hold me to it), the sickness even (which is part of the extra-terrestrial experiment--it rode in on a meteoroid, and is technically an extra-terrestrial life form). All released. And now roaming the island.
But, Hanso still has a problem, because during the original "incident" some of the rebellious researchers got out into the real world, and perhaps some of their work did too. Hanso has to collect the projects and hide them away from the world. Maybe destroy them.
This is where it starts to become a little unclear for me; but I definitely think that Christian was a part of the Dharma Initiative, and probably a researcher for it. He works on the "Life-Extension" project, and tests it on himself, making himself immortal. AND thus he is the "White Rabbit." Jack actually saw him alive, and Christian is making his way to go be with the other rabbits.
What if Michael's father was also a researcher for the project and somehow has passed down some "remote viewing" capabilities to his offspring? And Locke? Could he have been a part of the eugenics experiment, and somehow his mother managed to get him out of the project? The Rabbits release "The Numbers" which are a part of the Mathematical Forecasting project over the radio airwaves maybe looking for help, or as a message to other Rabbits in other locations, and they eventually find their way to Hurley. But Hanso can not allow all these loose ends of Dharma to be out in the world. And thus they send them back to the island. They are somehow responsible for getting the remaining rabbits (including, but by no means an exclusive list: Locke, Walt, Aaron, Christian, Hurley* and maybe Vincent?) onto the plane and having it crash on the island.
*Actually, I don't know if they actively were after Hurley, but they certainly knew of him after he won the lottery
I have no idea how the plane crashed. I do not know why some people were on the flight. I do not know why they survived. But I do know that most of the lostaways did not buy their own tickets, and were not supposed to be on that flight. Also, if Hanso were actively trying to collect the projects that were out there, it might help to explain all the emphasis on adoption---they are actively trying to collect Walt and Aaron. And maybe at one time Alex?
One last thought: in this scenario, maybe the Others or "Rabbits" are not bad, and when they abducted Walt, they did so to protect him from whatever it is that Hanso has planned. The real bad guys in this scenario is Hanso. They are the evil empire, and the Others are just members of the rebellion.
Like I said, I don't have all the pieces, and I suspect this will all fall apart once Wednesday's episode airs, but I can't shake the feeling that we've got some sort of rebellion going on here. I welcome any thoughts, criticisms, and ideas
ETA: They've changed the site. It no longer plays the rabbit/swirly message. For those of you who did not see it, it can be seen here
, although the entirety of the message can't be heard. Anyone get a cap of it whole?
