Thoughts about Time Travel


Without spoiling anything, the most recent episode of my friend Jason Sims’ podcast has a moment that relates to a subject I’ve given a lot of thought, involving time travel:

If I had the ability to travel through time, I would do some amount of the stereotypical time-tourism stuff, like watching the Apollo 11 launch or being at the Sermon on the Mount.

(But not the one with the loaves and fishes, because I am allergic to seafood.)

But that would only be like 5 percent of my time-traveling.

The huge majority of my time traveling would be going back to places that I miss, like eating at favorite restaurants that have closed or walking through places I worked that have been torn down or playing classic video games at the arcade.

In particular, there is a Mexican restaurant in Indianola, Miss., in the mid/late ’90s that would have gotten a lot of my future business.

Because these were favorite places of mine, though, it raises the possibility of past-me encountering future-me, which I feel it would be important to avoid. There are two reasons for this:

One reason is the cliché concern that it would create some sort of temporal paradox/anomaly thing that would destroy the space-time continuum. This is the lesser of the two concerns.

The bigger reason is this: If I assume that I’m going to actively avoid past-me being aware of the presence of future-me, then the fact that I’ve never seen myself do this is entirely consistent with the possibility that I will, in fact, do it.

I’ve been thinking about this for about 20 years now.

And even back then, I wondered how careful that would really require me to be. For example, if 22-year-old me were at a restaurant, and 52-year-old me walked in, would younger me even recognize me as the same person?

Factor in the facts that a) I’m not really going to be expecting time-traveling future older me to come in, so that’s probably not going to be my first thought*, and b) I’m honestly probably not paying a lot of attention to the other patrons anyway.

For example, the guys on the right in these two pictures from 22 years apart certainly favor each other, but if they were in the room together, do they really look “the most logical explanation is that one of them has traveled from the future” alike?

Supporting my theory is this: Several years ago, my friends Caleb and Lauren told me about the time they were at their favorite restaurant, and an older couple came in as they were leaving. (Or vice versa, I forget.)

And this older couple looked JUST LIKE OLDER VERSIONS OF THEM!!

And they now say that this restaurant has since made some changes so they don’t think it’s now as good as it used to be.

There are only two possible explanations: 1) The couple they saw was future-them, who had traveled back to the past to revisit their favorite restaurant when it was in its prime, or 2) It was an older couple that favored them quite a bit.

I, obviously, subscribe to option 1.

Which means that there is a good chance that I may already will have eaten again at Los Arcos in Indianola again in the future before it closed.

*Though I’ve already acknowledged that I’ve been thinking about this for 20 years, so if it happened since then, I actually probably am maybe more likely than average to think it’s time-traveling future me.
