The Invisible Bomber
Here’s a new rule about what constitutes a time-travel story: If the author claims that
there’s time travel in the story, then it’s a time-travel story. That’s the case
for this story, which doesn’t feel like time travel to me, but in the afterward of
The Omnibus of Time Farley says that the airplane bomber in this story becomes
soundless and invisible via a “laminated” model of space-time in which a series of
different worlds are stacked one on top of another, each just a short time in front of
its predecessor. According to Farley, “time-traveling will carry the traveler, not into
the future, but rather into an entirely different space-time continuum than our own.”
The plane becomes invisible by traveling just a short distance toward the next world
without reaching anywhere near it.
My thought on this is that the notion of time as a
dimension does not have anything to do with the stacking dimension. In fact, I don’t
think they can be the same dimension because that would imply that there is nothing to
distinguish a point in our space-time continuum from a point with the same space-time
coordinates in some other continuum.
P.S. I also didn’t care for the president’s
solution to the story’s problem.
We human beings live in a three dimensional space, or which time has sometimes been
called the fourth dimension. But did it ever occur to you, Mr. President, that we do not
extend in time. We never experience any other time than the present. Our so-called
space-time existence is thus seen to be a mere three-dimensional layer, or lamina,
infinitely thin in the time direction. There could exist another three-dimensional space
just a second or two away from ours, and we would never know it.
