Time Travel Tropes

The Hemingway Hoax

by Joe Haldeman

Literature professor John Baird and conman Sylvester Castlemaine hatch a plan to get rich forging Hemingway’s lost stories, but before long, Baird is confronted by an apparent guardian of the many timelines in the form of Hemingway himself.
— Michael Main
I’m from the future and the past and other temporalities that you can’t comprehend. But all you need to know is that yiou must not write this Hemingway story. If you do, I or someone like me will have to kill you.

“The Hemingway Hoax” by Joe Haldeman, Isaac Asimov’s Science Fiction Magazine, April 1990.

Blood Trail

by Kristine Kathryn Rusch

Detective Wheldon, the top man in NYPD Homicide is approached by two FBI agents who offer to let him go back in time two weeks to observe the 4th killing by a serial killer.

This is the first story in Future Imperfect, a 2001 anthology of 12 original time-travel stories, co-edited by the prolific anthologist Martin H. Greenberg (1941-2011) who was also a political science professor at the University of Wisconsin, Green Bay.

— Michael Main
When it became clear that time travel was even a remote possibility, the government bought a lot of scientists. Those who didn’t play got discredited.

“Blood Trail” by Kristine Kathryn Rusch, in Past Imperfect, edited by Martin H. Greenberg and Larry Segriff (DAW Books, October 2001).

SpongeBob SquarePants [s7:e09A]

Back to the Past

by Casey Alexander, Zedus Cervas, and Dani Michaeli, directed by Casey Alexander et al.

SpongeBob, Patrick, and their two superhero friends head back to the days when the old superheroes were young.

This device allows us to transport into the future or past, at a date or destination of our choosing. Unfortunately, the consequences of altering the order of history are so dangerous [thunder], we’ve chosen to leave it alone. So you mustn’t touch!

Nice and nerdy Lucy gets romantic advice from her future self via text messages.

Unknown: I’m u 10 years in the future.

— Michael Main
We can’t meet. Seeing each other physically . . . You have no idea what that would cause.

Displacement

written and directed by Kenneth Mader

Brilliant physics student Cassandra Sinclair finds herself running from the evil Initiative Organization—which includes her childhood friend Josh and a posh lady with an English accent—who are after the equations in her thesis notes that somehow (she’s not quite sure how) launched her on multiple slips back in time (we counted eight) that may or may not result in destroying yourself by getting too close to yourself, a closed timelike curve, quantum entanglement, and/or solving the Grandfather Paradox (without ever having anything that resembles the Grandfather Paradox, quantum entanglement, or a closed timelike curve). We suspect that writer/director Kenneth Mader had been reading “Experimental Simulation of Closed Timelike Curves,” but the actual science didn’t fully translate from the lab to the silver screen.

Handy Hint: The movie is eminently more watchable in a late-night group where everyone shouts “Great Scott!” whenever a character spews a sequence of pseudoscientific quantum mumbo jumbo that vaguely resembles an English sentence.

— Michael Main
We’ve been running simulations to resolve the Grandfather Paradox, and we experienced an unusual electromagnetic pulse at the school that was triggered remotely. We were able to locate the source, but I suspect someone may have taken our simulations a step further. . . . The equation in your daughter’s thesis notes may have actually solved the paradox. But they’re untested and now they’re missing, and you said Charles has been absent. Could he have taken them and induced an entanglement?!

Displacement written and directed by Kenneth Mader (Boston SciFi Film Festival, 7 February 2016).

Marley and Marley

by J. R. Dawson

Somewhat jaded 28-year-old Marley comes back through time to take care of 12-year-old orphaned Marley.
— Michael Main
He told me all the horrible things that would happen if I broke any Time Laws. Worlds would collapse. I would turn inside out. Important people would die and important things wouldn’t happen.

“Marley and Marley” by J. R. Dawson, Magazine of Fantasy and Science Fiction, November/December 2017.

See You Yesterday

by Fredrica Bailey and Stefon Bristol, directed by Stefon Bristol

Up in the ITTDB Citadel, our first attraction is naturally to the time travel aspects of any movie, even when the result is an incomprehensible time wreck resulting from a pair of teenage geniuses. That’s what’s on the surface here, but it also seems to be a metaphor for the even bigger train wreck of the racist society in the 21st-century United States.
— Michael Main
You’re missing the big picture here: If time travel were possible, it would be the greatest ethical and philosophical conundrum of the modern age.

See You Yesterday by Fredrica Bailey and Stefon Bristol, directed by Stefon Bristol (Tribeca Film Festival, New York City, 3 May 2019).

The Future of Another Timeline

by Annalee Newitz

Tess is a geologist (because, of course, geologists control the time travel of the giant ancient machines) and a member of the Daughters of Harriet (Senator Harriet Tubman, that is, from 19th-century Mississippi). On the surface, the Daughters are time travel scholars, but in reality, Tess and her fellow Daughters are fighting a pitched changewar for women’s rights against the oppressors known as the Comstockers. One more thing: While she’s at it,Tess also hopes to also save the souls of her teenaged self and her underground feminist punk friends in the 1990s, with a particular focus on their vigilante killing spree and young Beth’s abortion.
— Michael Main
All five Machines had limitations, but the hardest to surmount was what travelers call the Long Four Years. Wormholes only opened for people who remained within twenty kilometers of a Machine for at least 1,680 days.

by Chris Bore et al., directed by Joe Carnaham

After visiting his estranged wife, Jemma, at her top secret lab, retired special forces agent and ne’er-do-well Roy Pulver finds himself endlessly repeating the next day, which always starts with the same assassin in his apartment and always ends with Roy dead, even as he learns more and more about Jemma, their son Joe, Jemma’s work, and how to kill endless assassins.
