Ex Nihilo Obects and People

Time Travel Tropes

Weird Fantasy #13 (1950)

Only Time Will Tell

by Al Feldstein et al.

Start by reading Heinlein’s “By His Bootstraps” (1941), and then read this one. You’ll enjoy both and stretch your mind around the first ex nihilo idea that we’ve spotted in comic books. Note that the half blueprint itself does have an origin, and you can trace it’s timeline from that origin to the past and back again. It’s only the concept expressed in the blueprint that has no origin.
— Michael Main
—are the same piece!

“Only Time Will Tell” by Al Feldstein et al., Weird Fantasy #13 (EC Comics, May/June 1950).

Journey into Mystery #2

Don’t Look!

by an unknown writer and Jay Scott Pike

Yep, the mirror that Harold Whitney got from an odd old man really does let you see what people will look like in the future—a situation that we’d normally mark as a mere time phenomenon and tag as a simple kind of chronoscope. But the story also has a twist at the end that makes me wonder whether the old man was also a time traveler.
— Michael Main
I have here a strange invention, a mirror that will let you see how anyone will look at anytime in the future.

“Don’t Look!” by an unknown writer and Jay Scott Pike, in Journey into Mystery #2 (Atlas Comics, August 1952).

The End of Eternity

by Isaac Asimov

Andrew Harlan, Technician in the everwhen of Eternity, falls in love and starts a chain of events that could lead to the end of everything.
— Michael Main
He had boarded the kettle in the 575th Century, the base of operations assigned to him two years earlier. At the time the 575th had been the farthest upwhen he had ever traveled. Now he was moving upwhen to the 2456th Century.

The End of Eternity by Isaac Asimov (Doubleday, August 1955).

“—All You Zombies—”

by Robert A. Heinlein

A 25-year-old man, originally born as an orphan girl named Jane, tells his story to a 55-year-old bartender who then recruits him for a time-travel adventure.
— Michael Main
When I opened you, I found a mess. I sent for the Chief of Surgery while I got the baby out, then we held a consultation with you on the table—and worked for hours to salvage what we could. You had two full sets of organs, both immature, but with the female set well enough developed for you to have a baby. They could never be any use to you again, so we took them out and rearranged things so that you can develop properly as a man.

“‘—All You Zombies—’” by Robert A. Heinlein, Magazine of Fantasy and Science Fiction, March 1959.

Ijon Tichy

Ze wspomnień Ijona Tichego, pt. 4

Literal: From remembrances of Ijon Tichy, pt. 4

by Stanisław Lem

Ijon is unphased when Physicist Molteris lugs his time machine into Ijon’s sitting room, promising Ijon will be repaid for the colossal amount of electricity that will be consumed by the first trip.
— Michael Main
Zamierzałem, ale . . . widzi pan . . . ja . . . mój gospodarz wyłączył mi elektrycznoćś . . . w niedzielę.
I planned to, but, you see, I—my landlord turned off the electricity on Sunday.

Lem’s Star Diaries

Czarna komnata profesora Tarantogi

Literal: Professor Tarantoga's black room

by Stanisław Lem

Professor Tarantoga saves human civilization! After using his chronopad to investigate the leading scientists and artists in history, Tarantoga concludes that without exception they are lazy drunkards. So naturally, he sends smart young people into various eras to invent differential calculus, to paint the Mona Lisa, etc.—all while a pair of police inspectors have their eye on him.

“Willie’s Blues”

by Robert J. Tilley

A music historian travels back to the 1930s to uncover the real story of how Willie Turnhill rose from an extra in the Curry Band to tenor sax virtuoso ever.
— Michael Main
He thinks of me now as the one person who’ll be able to say who’s the original and who’s the plagiarist when “the other guy” does eventually turn up!

“‘Willie’s Blues’” by Robert J. Tilley, Magazine of Fantasy and Science Fiction, May 1972.

A Touch of Petulance

by Ray Bradbury

On his way home on the train, Jonathan Hughes meets Jonathan Hughes + 20 years and receives a warning that his marriage to a lovely young bride will end in murder.
— Michael Main
Me, thought the young man. Why, that old man is . . . me.

“A Touch of Petulance” by Ray Bradbury, in Dark Forces, edited by Kirby McCauley (The Viking Press, August 1980).

Somewhere in Time

by Richard Matheson, directed by Jeannot Szwarc

An elderly woman presses a pocket watch into a man’s hand, beseeching him to come back to her, and eventually) he does come back to her. We count this as science fiction rather than fantasy because of Professor Finney(!)’s attempt at an explanation of time travel via self-hypnosis, similar to the method in Jack Finney’s Time and Again (1970). In addition, the film may contain the first example of a looping artifact with no beginning and no end.

Wayne Winsett, owner of Time Warp Comics, tells me that this is his favorite time travel movie. Wayne is not alone in his assessment of Christopher Reeve and Jane Seymour, as the film now enjoys a mild cult following.

— Michael Main
Come back to me.

Somewhere in Time by Richard Matheson, directed by Jeannot Szwarc (at movie theaters, USA, 3 October 1980).

Timerider: The Adventure of Lyle Swann

by William Dear and Michael Nesmith, directed by William Dear

Now that I know that one of the Monkees wrote this time-travel yarn of a dirtbiker riding his motorcycle through a time portal and into the Old West, the universe begins to make sense.
— Michael Main
You shot it. What a bunch of dumb sons of bitches. You shot it—a machine, you butt-heads!

Timerider: The Adventure of Lyle Swann by William Dear and Michael Nesmith, directed by William Dear (premiered at an unknown movie theater, Austin, Texas, 27 August 1982).

Star TrekIV

Star Trek IV: The Voyage Home

by Steve Meerson et al. , directed by Leonard Nimoy

As the brave crew of the Enterprise are returning to Earth on a Klingon Bird of Prey to stand trial for the events of the previous movie, Spock determines that Earth’s demise is imminent unless they can return to 1986 and retrieve a humpback whale (which they proceed to do).

I saw this in the theater with Deb Baker and Jon Shultis during a winter trip to Pittsburgh for a small computer science education conference.

— Michael Main
McCoy: You realize that by giving him the formula you’re altering the future.
Scotty: Why? How do we know he didn’t invent the thing?

Star Trek IV: The Voyage Home by Steve Meerson et al. , directed by Leonard Nimoy (at movie theaters, Canada, 21 November 1986).

from The Teacher of Symmetry Cycle

Фотография Пушкин (1799–2099)

Fotografiya Pushkin (1799–2099) English release: Pushkin’s Photograph (1799–2099) Literal: Pushkin’s photograph (1799–2099)

by Андре́й Би́тов

In 1985, an author has visions of a time traveler named Igor from 2099. The traveler is being sent by his comrades in the domed city of St. Petersburg back to the 19th century, where he is tasked with capturing images and audio of motherland’s supreme father of poetry, Alexander Sergeyevich Pushkin.

Note: A dissertation by [ex=bare]Гулиус Наталья Сергеевна | Gulius Natalya Sergeevna[/ex] notes that this story is part of Bitov’s Teacher of Symmetry Cycle, which consisted of a series of avant-garde stories purportedly written by an obscure Englishman named [ex=bare]Э. Тайрд-Боффин | A. Tired-Boffin[/ex] and loosely translated to Russian by Bitov. The English version of “Fotografiya Pushkin (1799–2099)” was said to have been called “Shakespeare’s Photograph” (or possibly “Stern’s Laughter” or “Swift’s Pill”), and presumably it was about Shakespeare rather than Pushkin.

Sergeevna explains that all this artistic mystification was part of an extensive footnote to “Fotografiya Pushkin (1799–2099),” but up in the ITTDB Citadel, we’ve yet to track down the footnote. Perhaps it was part of the 1987 publication in [ex=bare]Знамя || Znamia[/ex], or maybe it did not appear until the story was published along with the rest of the cycle in Bitov’s 1988 collection, [ex=bare]Человек в пейзаже | Man in the landscape | Chelovek v peyzazhe[/ex]. It is not listed in the table of contents of [ex=bare]Преподаватель симметрии ] | | Prepodavatelʹ simmetrii[/ex](2008), which was translated to English as Symmetry Teacher (2014).

— Michael Main
. . . мы сможем в будущем, и не таком, господа-товарищи, далеком, заснять всю жизнь Пушкина скрытой камерой, записать его гол . . . представляете, какое это будет счастье, когда каждый школьник сможет услышать, как Пушкин читает собственные стихи!
. . . we will be able in the future, and, gentlemen-comrades, not such a distant one, to photograph Pushkin’s entire life with a hidden camera, record his voice . . . imagine how wonderful it will be when every schoolboy will be able to hear Pushkin read his own poetry!

It seeems that the only way Sam can fulfill his mission of stopping 17-year-old Cam Wilson’s older sister from marrying shithead Bob is to race Bob “for pinks” in hopes that Bob will lose his cool and show his true self, but that’ll only work if Sam (as Cam) and his buddy Jill can soup up Cam’s pink mommobile with a blast of nitrous oxide at exactly the right moment of the race.

SB-129

by Aaron Springer, Erik Wiese, and Mr. Lawrence, directed by Aarpm Springer et al.

The first of SpongeBob’s family to foray into time was Squidward, whose accidental cryofreeze took him two millennia into the future. Of course, even primitive sponges know that that was not actual time travel, but future-SpongeTrons point the six-limbed cephalopod to a time machine that took him on two actual time travel trips before returning him to his own time. No, we don’t know whether one of the future SpongeTrons is SB-129, but we do note that the production code for this episode was 2515-129.
— Inmate Jan
Well, why didn’t ya just ask? The time machine is down the hall and to the left.

Miri and Molly 1

The Magic Half

by Annie Barrows

As a middle child stuck between two sets of twins, eleven-year-old Miri Gill feels an outsider until one day in her attic room, she slips back in time from the 21st century to 1935 where she meets Molly, another eleven-year-old who needs her help.

Also in need of some help is the model of time travel in the story, which is a mishmash of popular representations that no person at age eleven or elsewhen should be exposed to. Specifically, I would have enjoyed an attempt to square the Branching Timeline implied by the hole in floor with the single nonbranching, static timeline and Ex Nihilo paradox hinted at by the time-travel device. I truly liked that ex nihilo paradox, and wish it had been explicitly dealt with rather than swept under the carpet.

— Michael Main
If you think about it too long, you’re going to go crazy, and then I’ll never get to your time.

Rocking My Dreamboat

The Chronicles of St. Mary’s 1

Just One Damned Thing after Another

by Jodi Taylor

Fresh from finishing her Ph.D., Madeline Maxwell (aka Max) runs into her high school mentor who encourages her to apply for a position with a cloistered group of historians called St. Mary’s Institute of Historical Research.
— Michael Main
Think of History as a living organism, with its own defence mechanisms. History will not permit anything to change events that have already taken place. If History thinks, even for one moment, that that is about to occur, then it will, without hesitation, eliminate the threatening virus. Or historian, as we like to call them.

— Michael Main
“Don’t you see?” says Terry. “We’ll just travel back in time and get a permit for the treehouse.”

Paradoxes of Time Travel

by Ryan Wasserman

Ryan Wasserman’s philosophical book is one of two books* that need to live on your nonfiction shelf. One by one and with complete reference to the past literature, he presents all the major paradoxes of time travel along with different models of time travel and arguments against time travel even being possible. Just get it and read it cover-to-cover. As a bonus, Professor Wasserman, who is on the Philosophy faculty at Western Washington State University, will cheerfully have discussions about time travel issues via e-mail with those of us up in the nearby ITTDB Citadel.

* The other, of course, is Paul J. Nahin’s Time Machines: Time Travel in Physics, Metaphysics and Science Fiction, Second Edition.

— Michael Main
Each of the foregoing cases involves a self-defeating act—an act such that, if it were performed, it wold not be. Self-defeating acts are obviously impossible, since the performance of such an act would imply a contradiction. Yet time travel seems to make such acts possible. This suggests the following line of argument against backward time travel:

(P1) If backward time travel were possible, it would be possible to perform a self-defeating act.

(P2) It is impossible to perform a self-defeating act.

(C) Backward time travel is impossible.
