DIMENSIONAL THEORY

Another popular fan theory to explain LOST was that somehow Flight 815 went through a time-space portal during its flight from Sydney to LA.

Fan Theory: Flight 815 flew the vortex of a time-space portal which allowed it to crash land on an island in a different dimension.

Once the viewers were told that the island was capable of moving in both time and space, theorists speculated that the cause of the island's properties had to be beyond the confines of Earth physics. Some thought that the plane could have gone through a wormhole, and instantaneously traversed the galaxy to a parallel universe. In a similar vein, the portal or vortex moved the plane into an event horizon bubble near a wormhole that was fairly stable, but shifting within our known universe.

The idea that the castaways were released from the boundaries of nature was helpful to explain away the inconsistencies and paradoxes of the time travel arcs. It would have to have some bearing on the fact that the off-island world was a duplicate of the characters' prior lives. When the first glimpse of the sideways world came into existence, fans thought that was confirmation that the characters were somehow connected to different but parallel lives in two different universes.

That would also come into play with the mental instability of many characters. The longer one would have been connected to their "other self" in a different dimension, some of dementia could logically follow.

Scientists do not believe that wormholes are stable. It would tear a part any object, including space ships and people, just beyond the event horizon. Wormholes are capable of consuming entire galaxies.

Theoretical scientists and science fiction writers believe that there is nothing in our knowledge base to refute the possibility of multiple universes co-existing in the same space and time. For example, a digital television signal can contain several different channels broadcasting at the same time.

This theory is still discussed as a better explanation for the show's end game, if one tries to refute the clear statement that all the characters in the sideways church were dead. But what is "dead" in another universe? Are the rules the same or different? They must be different if the second universe's projection to our universe caused an island to disappear.

There were clues to the mechanics of a time-space portal in the series. In the frozen donkey wheel room, there were hieroglyphs which stated certain positions or "Earth gates." A gateway to another place or dimension, besides the teleportation to North Africa? It is possible. It follows ancient religions that stated that a person's soul must go on a journey to another world. It is possible that these different concepts were pooled together at some point to try to create a story line to try to end the show on some sci-fi bearing. But this line of thinking was never wrapped up into a coherent story.
