In the hit show, "Fringe," a hole exists between two universes. People can travel back and forth. In both universes, the FBI has a Fringe Division that works to solve crimes and keep both universes safe.
Individuals have found met their alternates, with spine-chilling realization that they are not unique.
The show suggests that in both universes, people live similar lives.
Agent Olivia Dunham and Bolivia are both with the FBI's Fringe Division, but have different lives.
Agent Phillip Broyles was divorced by his wife in this universe, and his alternate is still happily married.
Dr. Walter Bishop discovered how to travel between universes, and Walternate works to try to repair the damage.
One college professor discovered his alternate was a serial killer. Their experiences were the same until one night in October when one met a woman who taught him how to control his sadistic impulses. The other did not.
An interesting question to ponder would be:
What would you say to your alternate?
It would be obvious to ask about the alternate's life, his or her experiences, likes and dislikes and so forth. The changes or decisions made by each person would be interesting.
Sociologists would have a field day measuring the similarities and differences between alternates.
Of course, they would also have an interesting study assignment to study those individuals whose alternate died. All those whose lives were affected by that person would be different.
It sounds like getting to see "It's a Wonderful Life" without help from an angel.
One dilemma would be getting the chance to meet the family of one's deceased alternate. For them, they might react as if they were seeing a ghost. Finding out what decisions were made after the death of the alternate might be disconcerting. Perhaps a favorite pet would be given to a new home. A girlfriend or boyfriend might marry someone else. Favorite possessions would be given away.
Not every alternate might become friends. Olivia and Bolivia aren't, but they have serious history between them. So far, no member of the Fringe team has made friends with their alternates.
Here's an interesting idea. Make a list of ten questions to ask an alternate. Be careful only to ask questions about those things you really want an answer to.
