The Time Machine and the Shmoe!


Cleaning man Donald Yubyutch is fed up with everyone at the time travel lab thinking he’s nothing but a shmoe. —Michael Main
Please sir, professor, sir! Can I go along with you on the time machine?
In the first of three panels, a group of scientists and engineers discuss their
                newly completed time machine while the cleaner looks on.

Short Story

a Haertel Complex story

Common Time

  • by James Blish
  • in Shadow of Tomorrow, edited by Frederik Pohl (Permabooks, July 1953)

Spaceman Garrard is the third pilot to attempt the trip to the binary star system of Alpha Centauri using the FTL drive invented by Dolph Haertel (the next Einstein!) The Haertel Complex stories provide little in the way of actual time travel, but this one does have minor relativistic time dilation and more significant differing time rates. —Michael Main
Figuring backward brought him quickly to the equivalence he wanted: one second in ship time was two hours in Garrard time.

Journey into Mystery #86

On the Trail of the Tomorrow Man


Zarrko, a mad time-machine-building scientist from 2262, believes that our nuclear weapons will enable him to take over the world of his time. He comes back to 1962 to steal one, and the Mighty Thor pursues him back to 2262.

The plot suffers from Alpha Centauri syndrome, where the time traveler might as well be from Alpha Centauri as from the future, but seeing the emergence of Kirby’s high-perspective artwork gives this issue a boost. In addition, the story provides a powerful image of the pre-Vietnam cold war era and its prevailing assumptions about the roles of women in society. —Michael Main
Ahhh—an ancient explosion of a nuclear bomb! The perfect device with which to conquer the twenty-third century!

Can You Really Go Back in Time by Breaking the Speed of Light?

Aether

  • written and directed by Jerry Brown, Jr.
  • (Youtube: SuperEpic Channel, 2 April 2018)

At the moment when the speedometer on the Aether spaceship clicked over from .999999c to 1.00000c, a collective cheer erupted up in the ITTDB Citadel. Was it a jaw-dropping dramatic moment? Seems unlikely, but we were looking for something to cheer for in this cryptic story of three men who headed to the future via relativistic time travel, only to find themselves trapped in post-apocalyptic outer space and quantum technobabble. —Michael Main
It nullifies Gödel’s theorem.

Mindscape #124

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.

Captain Nova


Captain Nova Kester travels back from a devastated future to warn an energy mogel about the impending climate cataclysm, but only young Nas takes her seriously. That happens when time travel causes you to revert to 12 years old. —Michael Main
