For the next two weeks, I’m going to look at typical aspects of science fiction that seem to have fallen out of favor for whatever reason. First up: time travel.
Why has this fallen into disrepute? Well, according to modern science, the amount of energy necessary to go back in time is infinite. And, of course, you can’t draw infinite energy because you’ll destroy the universe (personally, I think there’s a story there anyway). So, say the naysayers, time travel is out.
Now, if we want to get really science-y, we can talk about spacetime and how you can move forward in both time and space since they’re essentially the same thing, and blah blah blah.
My point is this: sure, maybe modern science says no. But here’s the thing – science, especially physics, changes all the time. Sure, back a hundred years ago when it was a less-developed field and we hadn’t figured out how to split atoms or that the universe was expanding, it was easy to justify time travel. Why couldn’t you go forward or backwards in time? There was nothing that said we couldn’t!
But even now, I don’t think you can rule it out. The universe is too fluid, our understanding constantly changing. There’s tons of fun theories right now that could be used to explain time travel. Sure, maybe the ol’ warp around the sun to go faster than the speed of light theory is bunk, but with a little twisting, the sky (the universe?) is the limit.
Besides, I don’t think you can knock it if you haven’t tried it.
And science fiction is about possibilities. What if this? What if that? To look at a classic aspect and write it off just because modern mentality says it ain’t so – that’s anti-scifi. A hundred years ago, no one thought we could make it to the moon either.
