One of the plot devices in fiction that engages me the most has always been the “alternate time-line”.
Cause and Effect
The idea of changing causes and seeing the resulting effects is a staple of science fiction.
Films like Back to the Future, The Terminator, TV shows like Quantum Leap and (certain episodes of) Star Trek all have stories that focus on how key events determine a certain future, and if those key events were altered, the future would be altered as well.
And the idea is not limited to science fiction. You may have seen or read Charles Dicken’s A Christmas Carol, or how about the similarly-inspired holiday “favorite”, It’s a Wonderful Life. In both stories, we get to see alternate time-lines, cleverly suggested as dreams.
There’s a whole list of alternate “history” stories listed in this Wikipedia entry.
What If? is a part of Critical Thinking
These tales all bring to the fore the question of What if? Indeed, the question of “What if?” can be used to generate entire stories. But it is also a way of exercising critical thinking. Only here, it is utilized in fiction, instead of real-life situations.
Baseball
Speaking of real life, the what if? scenario is perfectly illustrated in the American game of baseball. Like setting off a row of dominoes, a key play in baseball can result in a series of events (a player steals a base, causing the pitcher to throw to second, but the shortstop muffs the catch, and the runner from third scores so…) that gets one team closer to victory.
The interesting thing about baseball, unlike other sports, is that there is no time limit. Rather, the game is played until a key event occurs that results in one team having a 1 or more runs scored than the other team after the top of the ninth inning. Otherwise, the game can theoretically play for inning after inning, as long as the game remains tied.
This allows the game to have any number of key events. And in the end, the game announcers usually like to point out the “play of the game”, again, usually one of those key events (a crucial hit or a spectacular defensive play).
(I’m not a true fan of baseball, but I really appreciate that singular aspect of the game — that one play can affect the outcome of the game.)
Real Life Decisions
So because of my understanding, and appreciation of the fact we live in a “linear” existence, I often reflect on decisions that I have just made, or am about to make, and wonder about the resulting time-line that I’m “creating”.
I also like to look back on history, and ponder about key events that set the course of our current time-line.
It really helps to put things in perspective sometimes.
