Not to be confused with historical
fiction, alternate history is a fun subgenre of science fiction that starts
with a “what if?” What if Oswald never shot Kennedy? What if Hitler had not
declared war on the Soviet Union? What if cheese was never invented until the
21st century? Sometimes alternate history comes about in a science
fiction story because of time travel or dimensional travel or some such. In The Sound of Thunder by Ray Bradbury, a
time traveler falls off a levitated path and crushes a butterfly. The death of
the butterfly caused changes to the timeline thousands of years down the line.
This story is not strictly speaking an alternate history since the main characters
live in the future, but a similar mechanism has been used as the impetus for
stories in the alternative history genre. (By the way The Sound of Thunder has erroneously been attributed as the source
of the phrase “the butterfly effect”. Actually it comes from weather modeling
and chaos theory. Meteorologist Edward Lorenz coined the metaphor in a paper in
1969.)
But there have been many stories
envisioning a different history or a different present without the need for
telling why it happened; it just did, and now you watch how it unfolds. One of
the most famous examples of this genre is the Philip K. Dick novel The Man in the High Castle in which we
view the world of 1964 if the axis powers had won World War II. America has
been divided up into regions that are controlled by Germany or Japan, with a
neutral zone in between. It is interesting to contemplate the changes in such a
world. In Dick’s world of 1964 rocket travel is commonplace, but they are just
beginning to experiment with what will become television. Dick doesn’t go into
this, but one wonders if humans would have landed on the moon sooner or later
than they did in our world. You could argue sooner because of the German
prowess in rocket building. Or you could argue later because the impulse to
“beat the Russians” was not there. Would computer technology have happened more
quickly or more slowly in such a world? When you declare war on entire ethnic
groups, you lose diversity and the ability of looking at a problem from
different points of view. In our world, Hitler drove many Jewish scientists out
of Germany. This was one of the factors that helped lead to the downfall of the
Axis powers.
What if’s can lead to interesting
thought experiments, or they can just be fun. I have written a (yet to be
released) novel called Renfield’s Dream
which is half alternate history and half fantasy. The alternate history portion
takes place in a version of the 1980’s that is somewhat different than the one
I remember (for one thing, Richard Nixon is in his fourth term as president). When
you are starting such a story the possibilities are endless, but as you go, you
have to hone them down to just a few major changes. The more divorced from
reality a story is, the less interesting it is.
