The Island can only move (or be reached) on the Ring of Fire
I think we’ve had numerous hints that The Island is somehow connected to the Ring of Fire — the area of increased volcanic activity in the Pacific Ocean (http://lostpedia.wikia.com/wiki/File:Pacific_Ring_of_Fire.png).
Specifically, my theory is that The Island can only “move” (whatever that really means) to points located along the Ring of Fire.Â Alternately, The Island doesn’t even exist in our space-time dimension, and “windows” to The Island only open along the Ring of Fire.
Some hints about the Ring of Fire from seasons 1-5:
1) Flt 815 was near Fiji when it crashed.Â Fiji is in the ring of fire.
2) Eloise Hawking’s church and the Lamp Post are in Los Angeles.Â LA is in the Ring of Fire.
3) The staged 815 wreckage was placed in the Sunda trench near Java, in the ring of fire.
4) The Oceanic 6 were “rescued” after landing on an island near the Sunda Trench.
5) The freighter was last ported in Fiji.
6) Nuclear weapons tests in the 1950’s took place on Pacific Islands loacted in or near the Ring of Fire.
7) Polar bears are from the Arctic, and the ring of Fire passes right through southern Alaska.
8) The listening station that detected the sky turning puple was likely located either in the Antarctic or Arctic.Â If it’s the Arctic, that’s definitely in the Ring of Fire.
9) A submarine was used to get to and from the Island.Â A submarine might be able to descend into an ocean trench, which is a very common feature in the Ring of Fire.
10) Mysteries of the Universe Part 5 says a Dharma food palette accidentally dropped onto the Isle of Tonga, which in the Ring of Fire (although unsure if this is canon).
So why is the Ring of Fire special in the Lost universe?Â Three ideas:
1) It just is and that’s that.
2) Consider that ocean trenches and oceanic volcanoes are places where the Earth’s crust is particularly thin; they’re places where there is only a small amount of crust separates you from the Earth’s mantle. Maybe a thinner crust allows the Earth’s natural magnetic field to come through more strongly.
3) The solidified rocks deep in oceanic volcanoes actually incorporate some mantle material.Â Perhaps there is something inherently special/magical about the Earth’s mantle in the Lost universe.Â The Orchid orientation video alludes to “exotic matter”, and maybe the mantle is full of exotic matter, and just a little bit of it solidified in the extinct volcano on the Island and that’s where they built the Orchid station.
