Hey, everyone! I’ve got a new short story out (well, a flash story – it’s very short) out in this July 2019 issue of Galaxy’s Edge. I’m in a great issue, too, alongside such brilliant writers as Robert J Sawyer, Nancy Kress, Kevin J Anderson, Gregory Benford, and more! The best part is this: for this month only, you can read my story and others for free online! Just go to the website and check it out!
My story is my take on the zombie apocalypse and it is like, maybe, 1500 words, so you have no excuse not to read it. Go and check it out now!
So, Readercon this past weekend was a lot of fun, even though I was only there for one day. I saw two very interesting and engaging talks, one by Graham Sleight about Instrumentality and Science Fiction (is SF useful as a predictive tool for the future) and one by Austin Grossman about the origin of genre. Both fascinating, both mixtures of things I didn’t know and things I did, and both of which I’ll be chewing over for a while.
I was on a panel about World’s Worst Jobs that was great, great fun and I heard a bunch of crazy stories (and got to tell one, too). I gave a reading from Dead But Once that had a small audience, but was well received. To wrap it all up, I went to the launch party for Max Gladstone and Amal El-Mohtar’s This is How You Lose the Time War, which just sounds like an amazing book you should all go out and buy right now.
So, overall a great experience at another great Readercon!
I continue working through the summer on not just one novel, but two. Well, in truth, the first draft of the first novel I wrote this summer crashed and burned last week and I need to let the wreckage settle while I consider how to make another attempt (probably not until after Christmas). So I’m working on a second one now, which I won’t have time to finish before the Fall Semester kicks in, but I’m hoping I can at least get a sizeable chunk done. What kinds of books are they? Well, the first is a gritty space opera full of bizarre aliens and no humans whatsoever and the second is a more humorous thing set in a modern mall involving mythical creatures. So, in other words, totally different things. Is this good? Bad? Unwise? I don’t know. My agent seems to think it will be fine, but one wonders nevertheless.
In any event, onward and upward! Talk to you folks soon!
The inevitable “Who Would Win: Star Trek Vs Star Wars” conversation I find endlessly tiresome these days. Oh, yes, back in my younger years I’d debate phasers vs turbolasers and Klingons vs stormtroopers all you’d want, but now I’ve come to understand that the argument is fundamentally pointless. Since none of the things introduced in either universe are real and any technical specifications given to them are essentially made-up numbers, there is quite literally no point in debating who would win in an “actual” fight, since there is no “actual” to be used and Trekkies and Star Wars fanatics simply cannot agree on common assumptions in order to have a reasonable argument.
Even as I write this, whole legions of people are out there in the darkness, sharpening their sticks to come for me if I don’t declare their faith the winner.
But I’m not here to argue this (again). I’m just not. The side which wins is whichever side the plot is on, ultimately. And anyway, my favorite answer is “Neither – it’s the Imperium of Man of Warhammer 40,000.” On that score, pretty much anybody whose spent much time delving into 40k lore are forced to concede the point, if only because the Imperial Navy of the 40k universe is RIDICULOUS in scale and destructive power and everything else.
And, of course, even as I write that, there are those people out there, sharpening their spears and baring their claws, ready to pounce.
So I’m here to do something totally different. I’m going to suggest that Star Wars, Star Trek, and Warhammer 40,000 all exist in the same universe. Don’t buy it? Okay, but listen to this:
The Galactic Empire
The Star Wars universe is described as being a long time ago and in a galaxy far, far away. This means they can easily exist in the same universe, but the odds of them every crossing paths with the Federation or Imperium are exceedingly unlikely.
Compared to Star Trek, vessels in this galaxy are much faster than those in the Star Trek universe. Hyperspace is clearly a superior FTL system – more than just a warp drive, it is something that actually punches through the material universe of spacetime into a hyperspace dimension, enabling speeds that would make Mr. Scot insanely jealous. Their weapons technology is comparatively crude, but very powerful – turbolasers and blasters, in terms of their effects on targets, seem to have a lot in common with disruptors or phasers. Blasters even have a stun function (if rarely used).
Shields and armor are less sophisticated than the Star Trek universe and many ships suffer from glaring design flaws, but the ability for the engineers in this universe to build macro-structures (like the Death Star) cannot be underestimated.
And then there’s the Force. The people of this galaxy are connected by some interstellar energy field, indescribable and extremely powerful. Those who can commune with it can navigate ships through hyperspace, move things with their minds, even transcend death. Star Trek has very little comparable with this, but this is because they are a galaxy of much younger spacefaring species, as will be made clear soon.
The Federation of Planets
Meanwhile, in a galaxy distant from the Star Wars world and many ages later, a new (nascent) series of starfaring species are seeded onto many worlds throughout this galaxy. These beings more-or-less achieve interstellar civilizations at about the same time, astronomically speaking – within a few thousand years of one another – and spread out, come into conflict, make alliances, and so on. Their method of FTL travel – called Warp Drive – is a more primitive version of hyperspace, in a sense. It warps spacetime, but does not puncture it; ships glide along the wave made by the dilation effect (subspace).
Ships in this environment are small in comparison to Star Wars. Given that these civilizations are very young and there is no purpose (yet) for larger ships, this makes sense. Their weapon systems are similarly effective as those in the Star Wars world, though their computational, sensory, and command systems are vastly superior. Shields are better, targeting computers are better, and so on. If a battle were to occur between the Galactic Empire and the Federation, individual battles would be determined by the commanders involved. However, the sheer scale of the Galactic Empire and the vastly superior interstellar speed of its (more numerous) fleets would eventually crush the Federation, almost inevitably.
Then there is the matter of the Force. The Federation has no weapons to combat this since they are scarcely aware it exists. They don’t know it exists because they have yet to puncture spacetime in a way that would lead them to become aware of it. However, such powers do exist in the Star Trek world: the wormhole aliens of DS9, the “subspace predatory” species from another dimension described in one episode of TNG (can’t remember the title – the one where they discovered some aliens were kidnapping crew members and dissecting them without anyone’s knowledge), and even the empathic powers of the Betazoids. These can be seen as certain manifestations of “the Force” being used in material space. Psychic powers.
Parts of the Warp…
The Imperium of Man
Star Trek is set in the 23rd-24th centuries. The Imperium of Man exists from the 301st to the 400th centuries. Yes, that’s right – as much as 37,000 years in the future. Humanity is an elder starfaring race – they have, at this point, forgotten more about space travel and technology than either the Federation OR the Galactic Empire have ever learned. The Imperium rules a million worlds, possibly more, and is engaged in deadly, existential-threat-level wars on all sides at almost all times.
Their means of FTL travel? They enter what they call “the Warp” – a vestige of the ancient term bandied about by early humanity’s conquests in the age of Star Trek. But this is not a simple dilation of spacetime – they rupture it entirely, traveling into a kind of hyperspace. However, this hyperspace is now full of the psychic shadows of all the creatures who have lived before and been perverted by their thoughts and ambitions and dreams. In other words: the Force has long since fallen massively out of balance. There were no Jedi to keep the peace or, if there were, the Sith long ago rose up and destroyed them utterly. Now, hyperspace/The Warp is a realm of pure, terrifying chaos. It can, however, blink fleets across vast distances at speeds even the Galactic Empire cannot duplicate. Alternatively, it can devour fleets whole or send them lost and spinning through the mutating swirls of a hell dimension for millennia.
Star Trek exists in what the Imperium’s historians refer to as “the Dark Age of Technology,” where humans achieved dizzying heights of power and progress, but never realized that the Warp was as dangerous as it was. Eventually, they were cut off by warp storms and their civilization collapsed. The Imperium rose from the ashes, fighting every step of the way. It has blighted entire planets at a rate that would make the Death Star blush. It has access to technologies that would baffle any Starfleet engineer. Their elite soldiers are genetically engineered soldiers that would make Khan look like a designer baby intended for a photoshoot, not a firefight.
The Imperium obviously wins any battles with those other settings. They have psychic soldiers and psychic hunters the equal of any Jedi (the Culexus Temple, anyone? The Grey Knights?), they seem to have actually assimilated the Borg at some point in their history (Servitors), just as Q predicted (“you will surpass us”). They have gone so far beyond exploration that now they are the moldy remnants of a once great species in a way the Federation could scarcely comprehend. Humanity did it – it conquered the stars – only to discover that the stars are a terrible, cold place where war is unending and death assured.
And all of that is part of the same history of the universe – the Galactic Empire, in the thousand years before their time and ours, doubtlessly fell to the same conflagration that threatens to devour the Imperium of the Federation’s far future. The refugees of the Star Wars universe possibly seeded the very galaxy where humanity was born. Star Trek is the placid island in between two war-torn eras, where humanity still sees endless potential and hope for the future. But sooner or later, the daemons of the Warp will twist the hearts of mortals, and the Fall will begin anew.
(Author’s note: what follows is a bit of world-building for my current novel project, tentatively titled The Iterating Assassin)
There is a simple and clear distinction to be made between the Great Races of our Union and the Lesser Races. The Great Races are those species who have overcome the Great Filter and achieved interstellar civilization. This has most commonly culminated in the achievement of FTL travel with slipdrive, but not necessarily. The Voosk, for instance, achieved it with slowships of incredibly ingenious design and the Bodani with sublight, self-propagating probes, even if both species went on to steal slipdrive technology later in their development.
Those species who have failed to achieve interstellar civilization are, by definition, lesser than those that have. This can be seen as unjust, but this is not a question of justice, but merely a practical question of social and intellectual maturity. The Great Filter is the single most important challenge any civilization faces, and any civilization that has never grappled with it and won cannot be considered equal to those who have.
So, the Filter exhibits as a series of converging crises. Any one of these crises can destroy a planet-bound or even system-bound civilization utterly, and every one of them is inevitable. These crises are as follows:
The Resource Crisis
Any successful civilization reaches the point where it uses more resources than any given planet or star system can reasonably provide via what we shall generously term “conventional” means (i.e. means outside of quantum or dark matter sources). Without tackling the Resource Crisis, the civilization will starve itself out of existence.
The Belligerence Crisis
Any sufficiently advanced civilization has at its disposal weaponry able to destroy itself. Civilizations that cannot find a way to cooperate and avoid self-destruction obviously will never overcome the Filter, as they will become extinct.
The Population/Travel Crisis
Advanced civilizations will have a positive birth rate. Inveitably, this birth rate will exceed the civilization’s capacity to provide for that population. This can be a direct side-effect of the Resource Crisis, but even if provided for materially, the growing population will lead to added instability, exacerbating both the Billigerence Crisis and the Contact Crisis. There is some argument among scholars whether this is a distinct crisis at all, but rather just a side-effect of other crises. This is also called the “Travel Crisis” for some, since this crisis can be alleviated (however temporarily) by being able to escape the confines of a single planet or series of planets.
The Contact Crisis
Advanced civilizations often will make quite a lot of interstellar noise. This attracts the attention of interstellar species, who frequently seek to make contact. In the best case scenario, a system-bound species that encounters an interstellar species is quickly overcome and becomes a vassal state to the more influential and more powerful species. In the worst case, one of the planet-eating Marshals discover the civilization and consume it.
So, the barrier to becoming a Great Race involve solving the Resource, Belligerence, and Population Crises before the Contact Crisis happens and the civilization in question reaches a satisfactory resolution to said First Contact episode. This is a rare thing indeed, and hence there are only six Great Races (eight if one counts Skennite and the Marshals).
And what of the Lesser Races? Well, that is a complex tale, perhaps best illustrated with a case study: the Quinix of Sadura.
The Quinix are arachnids of great size and intellect. They seem to grow indefinitely, but the largest specimens have
been recorded as being some 3.5 meters in diameter, from leg to leg. On average, they are between 1 and 2 meters in diameter, with eight legs, each of which sporting a three-fingered “hand” of remarkable strength and dexterity. They have six eyes and can see deep into the infrared spectrum, which serves them well in their very dim natural environs.
Quinix are omnivorous, but have a noted preference for meat. Like most arachnids, they digest their food outside their bodies using a venom injected via their fangs. Given their large size, their fangs are not of considerable size. The Quinix do not kill with their fangs, but usually use tools or even their thread and cables to kill prey before eating.
The Qunix have spinnerets, like many arachnids, and are able to weave fibers of incredible strength and elasticity from their bodies. A single adult Quinix can weave several kilometers of fiber before exhausting their stores and needing to rest. When working as a group, they are capable of building complex structures of all manner of shape and size, all with their bodies.
The Quinix are clan-based organisms by dint of biology. Quinix females only lay a single egg during their lifetime (and the process of laying the egg and caring for it is usually fatal for the mother). If successfully fertilized, that egg hatches to produce many hundreds of offspring who are, as of that moment, a single social entity. These young clans receive guidance from their father’s clan and revere their mother’s clan as holy and sacrosanct. A complex web (please pardon the pun) of social and clan relationships governs Quinix society, tied together by a mind-boggling network of relationships. Mortality on Sadura is high (the vertical environment, the constant tectonic activity, the predators, and wars between so-called “oblique” clans – clans with no familiar connection) and therefore population numbers are low, overall.
As the Quinix live in a subterranean environment (and have to – the surface of Sadura is a radiation-soaked wasteland thanks to its proximity to its red giant sun), they have no conception of night and day. Indeed, they have a very poor reckoning of time in general and, to the extent that they do tell time, it is only via generational figures (clan related, again). They follow erratic circadian rhythms that are difficult for other species to tolerate, and do not seem to rush to do much of anything.
Additionally, their concept of life and death are likewise complex. For the Quinix, one’s life includes not only the animate existence of their body, but also the continued existence of their woven cables and webs. Without destroying the cables that they wove in life, a Quinix is still considered “alive” by all social standards. Therefore, buildings woven out of Qunix fibers are quite literally “alive” in a sense difficult for other species to understand or appreciate. Cutting a cable on purpose is an act of fatal violence.
Due to the confluence of these physiological and social factors, the Quinix have not and never will be able to exceed the Great Filter. While they developed metal-working technology (made difficult by Sadura’s highly flammable high-oxygen environment), their natural building abilities hampered their interest in exploring more complex materials science that would have allowed them to progress from the construction of iron-based tools and trinkets. They therefore have never and would never develop the technology capable of destroying themselves, are not successful enough to have a resource shortage, have (or had) a near-zero birthrate, and would eventually have been discovered and consumed by a Marshal if they ever developed a radio transmitter.
Fortunately and also unfortunately for them, they were discovered by the Dryth Solon, Kaskar Indomitable in C30.10, and have spent the last two and a half cycles as a Lesser Race under the auspices of the Union of Stars. This means they they will not be haphazardly eaten by a passing Marshal (good), but also means that any further technological or social advancement will be under the influence of the Great Races that have come to their planet. They are in a permanent state of arrested development.
Furthermore, and perhaps even more unfortunately, the changes wrought by the Union to make Sadura more hospitable to the Great Races has had an exacerbated effect on Quinix society and Sadura’s ecology. Stabilizing the tectonic activity has permitted huge cities to be built, resulting in a spike in the Quinix birthrate but also nowhere for those Quinix to go except into off-world settlements. They are a servant species on their own planet, their old clan wars and dreams of dominion crushed beneath the off-worlder’s technological superiority. The Quinix are gradually losing their cultural identity and are no longer masters of their own environment. It is difficult to say what will become of them, but whatever it is, they will never again control their own destiny. Unjust? Perhaps. But also inevitable and unavoidable for those who fail to overcome the Filter.
All things considered, being relegated to a servant species is vastly superior to many of the other alternatives: ecological or military extinction, or possibly being devoured by a void-dwelling macroorganism.

In Short Fiction News…
I’m happy to report I’ve sold re-print rights for my novelette “The Masochist’s Assistant” (which you might remember from the July/August 2017 issue of F&SF) to PodCastle, which means there’s going to be an audio version of the story! Very exciting news!
I’m going to be at PAXEast on Thursday, March 28th on a panel dealing with how to use Improv in your tabletop RPG game – I, along with a number of other performers, writers, and incredible gamers with whom I have shared a table on many a game night will talk GM-ing, gaming, plotting, planning, and everything in between. This is an excellent panel and I highly recommend it. I hope to see some of you there!
I just submitted a novel to my agent (a time travel caper) and I’m right now looking into what novel I’m going to write this summer (currently undecided), but of course I’m still writing short stories and novels and submitting things and pressing on. Ever forward – that’s the business! If there is any more news, you folks will be the first to hear about it!
Thanks for all your support, and we’ll talk soon!
I’ve been (slowly) re-watching Star Trek: Deep Space 9 for the last few months or so and I just got to that episode in season 3 where Nog, son of Rom and nephew to that scoundrel Quark, declares to Commander Sisko that he wants to apply to Starfleet Academy. It was a subplot I had sort-of half forgotten about but then came raging back all at once – Nog’s struggles, his long journey, and his eventual triumph. I just love that subplot. In fact, it might be my favorite Star Trek subplot of all time.
Now that I’m watching it as an adult, this storyline has some extra resonance for me. Besides being an author, my day job is as a college professor – a teacher – and Nog and his quest represent a very important lesson we teachers need to remember. To look at Nog from a distance, the kid is obviously a fuck-up and a lost cause. He gets bad grades in school, he is always goofing off, he gets arrested by Odo on a semi-regular basis, and his uncle Quark is a known criminal and low-life who associates with known criminals and low-lifes. To top it all off, he’s a Ferengi! No culture is more opposed to what the Federation represents – they are greedy, dishonest, selfish, and cowardly. There’s just no way in hell a kid like that has any business wearing a Starfleet uniform.
Sisko knows this. Hell, Nog knows this! Nog knows nobody expects him to amount to anything. His father is a permanent, laughable loser and his culture would never accept him going to Starfleet even assuming he could get in! But you know what this kid does? As soon as he comes of age, he scrounges together what money he has, walks into Sisko’s office (Sisko – the most powerful person on the station by far), shakes his hand, looks him in the eye…
…and offers him a bribe.
Because of course he does! That’s how Ferengi society works! This, to Nog, is what being a man is all about. This is responsible, adult behavior. And Sisko – bless him – realizes this. Everything tells him to show this kid the door – it’s probably a trick, a trap, some kind of prank – but…he hesitates. Sisko does something that makes me love him forever: he gives this kid a chance. He decides to trust him. He gives him a day alone with a cargo bay full of valuable stuff and lets Nog prove himself.
And you know what? Nog earns his trust. He proves he’s the hardest working kid on the station. He wants to be taken seriously. He wants this.
What I take away from all of this – the person I identify with – is Sisko. As a teacher, one is often faced with students who are…well…less than impressive at first glance. They show up late. They sleep in class. They don’t seem to be taking their education seriously. But the thing that I need to remind myself of is that I just don’t know what this kid is actually capable of. I can’t judge them based on superficial characteristics. Yeah, maybe they aren’t much good in my literature classes, but this person could very well become an excellent doctor or nurse or scientist. Hell, they might even have within them to become a wonderful writer or artist. As a teacher, it is part of my job to give them that chance – to allow them the opportunity to prove themselves, no matter what they look like or even how they act. Will I be let down? Sure, sure – happens all the time. But if a kid who’s been goofing off all semester comes up to me and asks if I can help them clean up their resume or give them advice on how to bring up their grades or ask me to recommend books for them to read to improve themselves, I remind myself of Sisko, sitting in Ops, looking at that sack full of latinum from an eager young Ferengi…
And I say yes.
And, like Sisko, I am often pleasantly surprised.
I’ve got a new story out! Check out “Applied Linguistics” in the Jan/Feb 2019 issue of Analog! It’s available online or in print form, and I’m pretty damned proud of it – it’s about language and learning and how cultural context can change, inform, or even create behavior and self-knowledge. And shape-shifting aliens on alien prison planets, so that’s cool, too!
There are a lot of other very cool stories by very talented authors in there, too. I especially liked “Ring Wave” by Tom Jolly and Adam-Troy Castro’s latest Draiken tale was a lot of fun. Check it out – you won’t regret it!
When I teach my expository writing students to do research, I usually tell them something along the lines of this:
Do not enter a research project with preconceived notions of what you will know when you are done. The point of doing research is to learn. It is your duty to read widely and get as full a picture of what you are studying in order to formulate an opinion about that topic. Your thesis (your argued point) comes after the research is done, not before.
This, I think, is good advice for scholarly research of all stripes. Don’t go in with preconceived ideas. Keep an open mind. Read deeply and widely.
Then, when I write novels, I don’t do anything of the kind.
I hasten to note that I’m not writing historical fiction, here – I’m writing speculative fiction. Scifi, fantasy, time travel – stuff like that. Everything I’m writing is, on some level, verifiably false. I’m making shit up all the time. So, the extent that I’m interested at all in actual facts – whether historical or scientific – is somewhat limited. That limit is the very low bar that is suspended disbelief.
Basically, if I can fudge some actual aspect of history without knocking the audience out of the story by violating their suspension of disbelief, then I can totally get away with it. Because, sure, they didn’t have potatoes in medieval Europe. But they also didn’t have magic or elves or gnomes. And this also isn’t medieval Europe. So what’s it matter, anyway? They’ve got potatoes in their stew – deal with it.
Now, of course, some audiences are going to be more sensitive towards this stuff than others and, furthermore, certain kinds of stories are going to require you to meet a higher standard of suspension of disbelief than others. For instance, I’m currently writing a time travel novel and, since it involves my character traveling back to actual places and times in actual Earth’s history, I have had to do a variety of research to make those places seem authentic. I’ve done research on 18th century American currency, military honors of the Roman Empire, card games played in Port Royal Jamaica in 1670, and who the Lakers were playing on December 8th, 1976 (the Pacers – the Lakers lost).
This research, though, takes a different form than what I would call actual academic research. I don’t need my answers to be correct, exactly – I just need them to be plausible. Furthermore, when I’m doing research like this, it’s to establish a very specific effect in a very specific scene that often happens only once in the whole book. I do some research online for a little while and, if I can’t find an answer that looks suitable, I change the scene so that I no longer need that specific answer anymore. I’m not going to sit down and read a whole book on the urban development of South Boston in the 1950s just so two paragraphs in the novel are 100% accurate, nor am I about to subscribe to a special research service or trek to some distant library just to know what color Ben Franklin preferred to wear when out about town. It just isn’t that important, ultimately.
So, in other words, I do research for books like this in the exact wrong way – the way I tell my students not to. I go in with a preconceived goal in mind (“I need a cool card game for my protagonist to play against pirates”), I do the barest minimum of responsible research (YAAAAY Wikipedia!), and I glean just enough information to make it look like I know what I’m talking about without, you know, actually knowing what I’m talking about.
I am bringing this up mostly because, in the last few weeks I’ve asked some people some relatively minor historical questions and received, well, rather extensive details that, while appreciated, aren’t really necessary. This has been from friends of mine who are academics and librarians and historians for whom I have the greatest respect, and therefore I kinda feel bad telling them “well…actually…I really don’t care what the answer is anymore. I’ve changed my mind.” Because I’m not really an academic or a librarian or a historian. I’m a showman. All writers are, ultimately. And while we might enjoy doing research about this or that, the research is not the end we seek. We’re telling a story. And story always, always comes first.
Hey, folks! I mentioned a few weeks back that I had a story in this month’s Analog (on newsstands now!), but I’m back to tell you that I have an article up on their blog right now which is probably the closest thing to an academic paper I’ve written in a long while (and it is very, very far from an actual academic paper). Check it out here! It’s all about optimism and pessimism in post-apocalyptica!
After having a conversation with my agent the other day, I’ve decided my next novel project is going to be time travel based. I wasn’t really planning to write this particular novel at this particular time, but he feels its the best career move right now and that’s basically what I’m paying the guy for – his advice – so why wouldn’t I take it? Anyway, the point here is that I’ve been thinking (a lot) about time travel in stories today and I want to share some of my ramblings.
One of the questions I’ve gotten recently is how the character in my time travel story is going to travel through time. What are the rules, in other words? Is time linear or non-linear in this story? Are we going to be dealing with the Grandfather Paradox or the Butterfly Effect or what? What about free will? Now, it just so happens that I have answers to these questions, but I’m not going to list them out here today. Instead, I’m going to talk a fair bit about how those questions aren’t actually that important. Or, at least, not as important as they first appear.
Time travel stories, you see, are really never about how time travel is accomplished. Never. Time travel stories are actually all about why the characters in question are traveling in time in the first place. This is also true more broadly of many science fiction stories of whatever subcategory – the special technology is usually more a metaphor for something present and actual rather than a literal exploration of technological progress – but it is particularly true of time travel, since, of all speculative technologies, time travel is possibly the least plausible outside of traveling at relativistic speeds (and then you could only go one direction – the future). If you want to go back in time instead of just forwards (in other words if you want an actual time machine), you kinda have to throw away most known physics anyway. If you’re doing something that impossible, does the fact that you’re traveling by Police Box or hot tub or phone booth really matter?
In other words, the rules, in large part, are arbitrary. There is no “right” or “wrong” way to tell a time travel story in terms of how the deed is accomplished and the rules surrounding said deed. Do we really question that the time machine in the Terminator can only send organic matter? I mean, it makes no sense, but do we care? Likewise, in Back to the Future, the Flux Capacitor makes absolutely zero sense, but, again, we don’t really care. We don’t care because we aren’t watching to movie to learn about how time works. We’re watching the movie to revisit our past.
And that’s really the crux of it: the journey through time is always (always) a metaphor that directly pertains to the main character’s conflict. Sarah Connor has to face the reality of her world ending and how best to prepare for that (the precise dimensions of that preparation and what it symbolizes varies from film to film). Marty McFly has to come to terms with his own parents and, thereby, his own identity. It is a crisis of self confidence, not a Hill Valley crisis. Even the Doctor and his TARDIS aren’t exploring space-time to teach us lessons about history, but rather to explore the human condition (and an outside observer’s opinion of it) in infinite contexts and scenarios. It’s not a show about aliens at all – it’s a love letter to humanity.
So, if you’re going to put together a time travel story, how you have the character traveling through time is a question subservient to why you want them to travel through time to begin with. Depending on what your purpose is – what themes you want to explore – the way time travel happens will itself be altered to fit your narrative goals. And you can do this, too! Time machines are impossible – as impossible as magic and even more impossible than things like hyperdrive or lightsabers or giant battle robots. In other words, it’s something of a blank slate – tell the tale you need to. Your audience isn’t tuning in for technical merit – they’re expecting a story about the human condition.
