"1956 Forbidden Planet" LOST theory:
Think we can all together build on this core theory, explain everything, and even predict/innovate new stuff!
Brief, I'll try (Yoda).
"Forbidden Planet" was released in 1956, and starred Anne Francis, Walter Pidgeon, Leslie Nielsen (!), and Robbie the Robot. The planet had a natural, almost infinite energy source which the Krell, an ancient race, leveraged with their technology. One device measured and developed the psyche of Krell children. This device could also create a form of whatever you imagined such as Altar (Anne Francis). HMmmm …
Unknowing to the Krell, the device also tapped the subconscious (Id), particularly evil cognitions, and independently acted on them, particularly when used by Adults. It is why both the Krell and the planet were self-destroyed.
Perhaps our favorite Island has a natural, unique energy source that Dharma technology tapped, probably to explore animal/human psyches to amplify good, perhaps control (e.g., dolphins). Their technology also unintentionally (or perhaps intentionally) tapped evil subconscious cognitions, and acts on them, frequently independently of the technologists. Why "The Others" chant they are the good guys cuz necessary for their survival.
Energy takes/changes into many forms such as purple light, magnetic, Smokey, human/animal forms … it even can change time depending on the applied technology! For example, a copper coil wrapped nail is non-magnetic until a current is applied ... how pinball machines work. Energy, both naturally and unnaturally, changes form. Perhaps the numbers are the key energy states/levels (or Dharma computer input codes) that Dharma discovered to control/tap the Island’s unique energy. Perhaps new or different numbers can cause dramatic better and/or worse results … a current active Island project.
Maybe the Dharma technology tapping the Island energy source senses psyches, both independently and dependently - even globally, and sometimes acts. Perhaps "Bad Dads" cause strong psyches that are more easily sensed, connected, and acted upon that resulted with our select passenger group, plus may explain why “Bad Dads” are an Island/technologist focus. Dharma+ recruited/recruits needed folks such as Juliet, Desmond, Patchy, etc. for various purposes, and holds them captive by threatening to act on their or their relation's subconscious fears. Perhaps Ben/French's daughter's boyfriend is a nasty example, Juliet is compliant, and why French Danielle avoids her Alex.
Also, since kids are mostly innocent/good, and they may be particularly sensitive to Dharma technology/Island, they may provide some safety for the exploration, maintenance, and operation of Dharma technology. And, their good psyches may be more greatly independently tapped by Dharma technology/Island and acted on. SOooo, Walt reads a polar bear comic, we have a polar bear. Locke seems a genuinely good guy, so he can walk thanks to the sensing and acting technology/Island … but Ben not so much, so he cannot walk at least yet.
Ben controls folks with threatened worse fears, why his "box" created Locke's "Bad Dad" for Ben to control Locke. Ben may be an original innocent kid who more safely explored, maintained, and operated Dharma technology, but he has naturally aged, making him less useful. Also, the need for Island surgeons perhaps suggests the application of animal/human implants that connect/amplify with Dharma technology and the Island’s unique energy source.
The purge may have been when some Dharma folks became sort of religiously against the observed evil being created and applied. These folks adopted some existing religious-like beliefs/practices, and they were purged with some escaping into hiding (French) or made a deal like Patchy. The Others executed the purge with their armed police, and now control at least some of the access to the Dharma technology, though they can't control or understand it completely.
WOW!
