Time travel without paradox.
The idea of being able to run around history like a jogger runs around
a track has always been fraught with the obvious loopholes.
What if you go back and kill your Granddad when he was a kid?
How could you then be born, grow up and live to go back in time
and kill Granddad?
If time travel is possible, then where are all the time travelers? We
can’t be SO boring that NO ONE ever comes back to catch some of
our act…can we?
If I nuke the founding fathers in 1776, and the United States is never
launched out of beta mode, how will I recognize anything of the
world I return to? And who there will remember me?
The answer to the Granddad Paradox, as well as the 1776 Massacre,
may be that it simply is not possible to return to the present – that is,
you can’t fast-forward into the future. So kill Granddad, but you’ll
likely end up prosecuted for murder and considered a lunatic, too.
And as for the interest of future generations in us, that might depend
on just how long from now time travel develops. For example, this
is the 21st Century. Suppose this is just the beginning of human
history and time travel isn’t achieved until the 1,953rd Century? Not
counting the eras B.C., that’s 1,952 centuries to explore. Do we really
stand out in this crowd, or will we be explored by a relative handful
of the curious?
And what if such time travel only works on the organic subject and
not on his clothes, tools, weapons or medicines? An ordinary appearing
human claiming to be from “the future” with no evidence save his
brain would swiftly be labeled either “looney” or “psychic” (for
predicting major events). There are plenty of these fellows – maybe we
should heed them carefully instead of looking away and dismissing
them.
And what would it benefit such a stranded voyager to ‘fess up?
Time travel, like suicide, may be a one-way journey.
