Since season one of the
show the only thing on everybody's mind was the island. What the bloody hell
was it? For a while people thought the whole show was Hurley's dream and the
island was just a figment of his imagination. Other people thought the island
was purgatory and that everybody died when the plane crashed (they weren't too
far off with this guess). The island is something a little more complicated
than that.

The reason the radiation is bad is because it contains
the smoke monster on the island. If the radiation is let loose then the smoke
monster can leave the island and do bad things elsewhere, I don't know (this is
where the story got a little farfetched).
The physical cork as seen in the finale that keeps the electromagnetism from leaving the island. (Who'd have thought they were actually talking about a REAL cork?) |

In addition to all of this other mumbo jumbo, the island
can move! It can relocate itself as long as someone turns a giant wheel. The
only rule is the person who turns the wheel is not allowed back on the island.
So that's all the island really is. It's a container for
electromagnetism. This is just in its physical state. The island has a much
larger, spiritual purpose in the lives of the characters which is explained in
the finale.
