Beyond the Time Barrier


Major Bill Allison flies the experimental X-80 into the year 2024 where a plague has turned most humans into subhuman mutants and the rest are mostly deaf, dumb, and sterile. Once there, the leaders of an underground citadel (not to be confused with the ITTDB Citadel) have plans for him to marry the beautiful telepathic (and possibly non-sterile) Princess Trirene, and thereby re-populate the world. But together with Trirene and a small group of scientists, he devises a plan to return to his own time and prevent the plague from ever occurring.

The flight to the future is explained by scientific gibberish that contains a high concentration of mumbo jumbo, but the gist of it is that the speed of Allison’s plane (around 10,000 mph) added to the rotational speed of the Earth plus the speed of the Earth’s orbit around the sun plus the speed of the Solar System around the center of the galaxy plus maybe another speed or two, managed to bring his total speed close to that of light, which brought him to the future. Apparently, reversing his plane’s path is all that’s needed to return him to the past (ideally with Trirene beside him).

A self-defeating act paradox is set up nicely (if Alison stops the plague, then the citadel in the, future won’t be there to send him back to stop the plague), but the issue is never explicitly discussed and the ending of the film is inconclusive on the matter. Nevertheless, I commend the film for being the first to raise the issue of time travel paradoxes, albeit in the background. —Michael Main
I may be able to prevent it: Is that what you mean?

Time Was


Time travel via a spaceship that got too close to an uncharted black hole. Our hero, Caleb Hornblower, survives to have a romance with Liberty Stone, a woman from a couple hundred years before he was born. The romantic element is definitely stronger than the science, but there are some interesting discussions about past versus future technology and different social norms. There’s also a fun ride on an aircycle! And a bit of comedy when Liberty’s parents arrive unexpectedly. But only the one time travel event is documented, so this remains heavier on the Romance than the Time Travel.

The story continues in a 1990 sequel, Times Change. —Tandy Ringoringo
The cockpit lights went out, leaving only the whirl of kaleidoscopic colors from the instrument panel. His ship went into a spiral, tumbling end over end like a stone fired from a slingshot. Now the light was white, hot and brilliant. Instinctively he threw up an arm to shield his eyes. The sudden crushing pressure on his chest left him helpless to do more than gasp for breath.
Standing by a creek in the woods, a dark-haired man draws a woman toward him
                for a kiss.

Times Change


Jacob (J.T.) Hornblower, astrophysicist, deliberately travels back a couple of centuries to shake some sense into his brother Caleb, who had foolishly (in J.T.’s opinion) decided to stay in the past. A little more science than the first book in this duology, but still heavier on the romance angle, as J.T. finds himself strongly attracted to Sunbeam (Sunny) Stone. Both J.T. and Sunny are opinionated and bullheaded, as well as having blackbelts, so there is also more conflict in this book. The documented return trip to the future includes a brief description of physical side-effects. —Tandy Ringoringo
And now he stood and wondered. If he dug for it, he would come upon the same box. The box that he had left with his parents only days before. The box would exist here, beneath his feet, just as it existed in his own time. As he existed.

If he dug it up now and carried it back to his ship, it would not be there for him to find on that high summer day in the twenty-third century. And if that was true, how could he be here, in this time, to dig it up at all?

The Flash, Season 1

  • written and directed by multiple people
  • (The CW, USA, 7 October 2014) to 19 May 2015)

Time travel is implied right from the first episode of the CW’s rendition of The Flash where a newspaper from the future is seen in the closing scene. The rest of the first season builds a fine time-travel arc that includes a nefarious time traveler from the far future, a classic grandfather paradox with a twist (sadly not examined), a do-over day for the Flash (which Harrison Wells calls “temporal reversion”), and a final episode that sees the Flash travel back to his childhood (as well as a hint that Rip Hunter himself will soon appear on the CW scene). —Michael Main
Wells: Yes, it’s possible, but problematic. Assuming you could create the conditions necessary to take that journey, that journey would then be fraught with potential pitfalls: the Novikov Principle of Self-Consistency, for example.

Joe: Wait—the what, now?

Barry: If you travel back in time to change something, then you end up being the causal factor of that event.

Cisco: Like . . . Terminator.

Joe: Ah!

Wells: Or is time plastic? Is it mutable, whereby any changes in the continuum could create an alternate timeline?

Cisco: Back to the Future.

Joe: Ah, saw that one, too.

How Time Travel Could and Should Work

  • by Sean Carroll
  • from Mindscape 124 [podcast], 23 November 2020

Alas, Sean Carroll doesn’t pull any punches in his realistic assessment of the kinds of time travel that are or may be possible under the laws of physics as we know them in our universe. Or, as Professor Carroll himself puts it: “. . . podcasting isn’t for the squeamish.” In my layman’s understand of his most excellent explication, time travel aficionados have two physical phenomena on which to hang their Hat Things:
  1. Time Dilation: Under the laws of Einstein’s special relativity, a fast traveler who leaves the Earth, zooming around for a while at near light speed before returning, will experience less passage of time than those who stay in the more-or-less fixed reference frame of Earth. How cool is that? Yes, you can travel as far into the future as you like, so long as you have a means of zooming up to a high enough speed and returning. (And according to general relativity, time dilation also occurs inside a high gravitational field, although I didn’t notice a discussion of this sort of time dilation in the podcast.)
  2. Closed Timelike Curves: The second hope for time travelers are certain distributions of matter that (according to Einstein’s equations of general relativity) result in directed paths through spacetime in which a traveler along the path is always moving forward through time—and yet completing a full circuit of the path returns the traveler to the starting point in both space and time. That’s the good news. The bad news is that such paths, called closed timelike curves, might only be possible in the presense of infinitely long rotating cylinders or other physical conditions that may be impossible to engineer.
Up in the ITTDB Citadel, many of us found ourselves in a disquieted state at this point in Professor Carroll’s podcast (roughly the two-hour mark). Some went to bed early in a kind of daze; others decided it was time for a long walk through the lonely ice paths that surround the Citdel. But for those with the fortitude to keep their ears glued to the pod, there was a great reward. Carroll had already waded through the swift, waist-high currents of causality, predeterminism, free will, the A Theory of Time, the B Theory of time, and more. But now he was ready to dive into deep, uncharted waters. Yes, now he was ready to leave known physics behind, to talk about branching time that went beyond the Everettian Many Worlds of Schrödinger’s equation, and to consider what kind of a world would be needed to allow stories such as Back to the Future and Looper to consistently hold together. With this in mind, he devices a four-pronged theory that concludes with what he calls Narrative Time. For me, narrative time shares some features with the time model of Asimov’s The End of Eternity (a model that we call Hypertime in our story-tagging system), but it goes far beyond that.

Suffice it to say that when all the Librarians up in the Citadel woke from their sleeps and returned from their treks, we had a celebration that was strident enough to raise Lazurus Long himself from the dead (if he is dead, that is). —Michael Main
I think that if we really try hard, we can make sense of this. But there’s a rule in physics or whatever that the more surprising and weird the phenomenon is, the more you’re gonna have to work to introduce some weird elements into your theory to explain it. That’s not surprising, right? So we’re gonna need some leaps of faith here, but I think I can come up with the scheme that involves four ingredients on the basis of which we can actually make sense of Back to the Future, Looper, and other similar movies.
