The Star Trek Fan Community’s Worst Theories

A Star Trek-themed spoiler warning.

Spoiler Warning: There are spoilers ahead for practically the entire Star Trek franchise, including recent seasons of Picard, Strange New Worlds, and Starfleet Academy.

I like to engage in a bit of theory-crafting here on the website! If you’re a regular reader, you might’ve followed along with my weekly Discovery and Picard theories while those shows were on the air. Or perhaps you clicked on one of my viral theories speculating about Unknown Species 10-C, Q, or Vadic. Or maybe you’re brand-new to Trekking with Dennis… in which case, welcome! But my point is that I like Star Trek fan theories, I write a lot of Star Trek fan theories, and I get a *lot* of things utterly wrong.

I give that caveat for one important reason: this piece, in which I’m going to demolish some fan theories that I’ve found doing the rounds in the online Trekkie community, is meant to be tongue-in-cheek! I’m trying to have a bit of fun with the Star Trek franchise in this landmark sixtieth anniversary year, and picking apart some fan theories I’ve come across on social media seemed like it could be a way to do that. But I’m not taking this too seriously, and you only need look at my own fan theories to see how bad some of them were.

Brace yourself. Things are about to get… silly.

More than ever, I encourage you to keep in mind that this is entirely *subjective, not objective*, and that we’re dealing with non-canonical fan theories which are likely never to be confirmed nor even referenced on screen. This is just for fun, it’s supposed to be a light-hearted exploration of some of the Trekkie community’s “wilder” and more “out there” ideas, and it’s just one person’s take on things, at the end of the day. So please try to keep all of that in mind as we go through these theories!

I visited a few different Star Trek social media pages and channels, collecting twenty-five theories that I thought sounded… well, to be blunt, I thought they sounded kinda silly. Some of these seem to have been written almost as parody, but others did seem to have elicited debate, and clearly have believers. But in any case, all of these made interesting (or weird) points, and I thought breaking them down could be a bit of fun as we continue our year-long celebration of the franchise’s sixtieth anniversary.

These theories cover all kinds of topics, and span the breadth of Star Trek’s history, from The Original Series all the way through to some of the most recent episodes of Starfleet Academy. Some fans have been, shall we say, especially *creative* with their ideas! Which is fantastic. I adore the Star Trek fan community and how passionate folks can be. As I’ve said many times here on the website: crafting a theory is a great excuse to spend a bit more time in Star Trek’s wonderful galaxy, and even though I may disagree vehemently with a theory, I love that Trekkies all over the world are so invested in this franchise.

We’re going to get into the theories now, so consider this your final content warning. This is your last chance to jump ship if you need to avoid spoilers or if you don’t want to come across some potentially controversial Star Trek opinions! The theories below are in no particular order.

Theory #1:
Dr McCoy knows that he’s a character in a TV show.

Still frame from Star Trek: The Original Series Journey to Babel showing Dr McCoy.
Leonard “Bones” McCoy.

In The Original Series, there were a handful of moments that seemed to break the fourth wall – i.e. where characters within Star Trek seemed to acknowledge the audience, or that what was unfolding on screen might not be real. Dr McCoy was a key part of one of the most (in)famous fourth wall breaks in The Original Series: the closing scene of the Season 2 episode Journey to Babel. In this scene, Dr McCoy remarks that he “finally got the last word,” after shushing Kirk and Spock – seemingly referencing other episode endings in which Kirk, Spock, or another character would say the closing line or remark on what had transpired. Furthermore, McCoy seems to say this while looking *almost* straight into the camera.

Without getting too nitpicky, I think we can debunk this one by explaining that McCoy was simply commenting on Kirk and Spock’s tendency to talk over him in-universe, rather than anything more meta! And the choice of camera angle, rather than hinting at McCoy somehow being self-aware, was merely a close-up. The Original Series did close-up shots like that all the time, and McCoy’s gaze is slightly off to one side, not straight down the lens. There’s nothing in canon to suggest that Dr McCoy is somehow self-aware of his status as a character, and anything that hints otherwise can be written off as a quirk of the show’s production or writing.

Theory #2:
The show T.J. Hooker depicts Kirk’s adventures on a holodeck.

Poster/box art for T.J. Hooker.
It’s Captain Kirk!

T.J. Hooker stars William Shatner in the lead role, and if you don’t know it, it’s a police procedural show from the ’80s. Besides Shatner’s role, Leonard Nimoy had a small role in one episode (and directed another), and James Darren (DS9′s Vic Fontaine) was a regular character. The series was in production alongside three Star Trek films – The Wrath of Khan, The Search for Spock, and The Voyage Home. But… that’s it. There are no overt references to Star Trek in T.J. Hooker, nor to T.J. Hooker anywhere in Star Trek – at least, not that I can recall.

If fans want to watch the show and make this inference… I mean, there’s nothing stopping you anymore. A few years ago, I might’ve said that the holodeck is a 24th Century creation, but Strange New Worlds has blown that theory out of the water. Holodecks clearly did exist at the time of The Wrath of Khan, and to be honest, I could see Kirk choosing to play make-believe as a cop in the ’80s. Obviously this isn’t and never will be canon… but don’t let that stop you!

Theory #3:
Borg “transwarp” is actually the mycelial network (from Discovery).

Still frame from Star Trek: Picard S1 showing the Artifact at transwarp.
A Borg Cube exiting a transwarp aperture into normal space.

I think we have enough context to fully debunk this one, right? Discovery’s mycelial network and Borg transwarp behave completely differently to one another, with the USS Discovery able to “jump” instantaneously to points across the galaxy, whereas Borg vessels enter a transwarp network and are accelerated to vast speeds. Borg transwarp is way quicker than warp speed and clearly allows for much faster transport than anything 24th or 25th Century Starfleet is capable of. But it lacks the instantaneous movement or the “jumping” effect of Discovery’s mycelial network. So I think that alone rules it out.

One thing that Star Trek’s writers usually do well is keep the intricacies of different technologies pretty vague. We know that dilithium crystals moderate the antimatter reaction in a warp core… but what that technobabble actually means, or how it all truly works, is a mystery. And you could argue that Borg transwarp is even more mysterious; just because no Borg character ever said the words “mycelial network” doesn’t mean they don’t have access to that technology. I will concede that it stands to reason that, if the mycelial network is a known phenomenon in the Star Trek galaxy, the Borg would be aware of it. But that doesn’t mean it’s how their transwarp network operates, and there are enough differences between how they appear on screen as to render this one null and void for me.

Theory #4:
Transporters beam out everyone’s bodily waste.

Star Trek art of a giant poo on a transporter pad.
Yuck.

Uh, sure… *that’s* what the Federation uses transporters for. Rather than going to the toilet, no one in the future is potty trained, and instead, transporters automatically empty everyone’s bladders and bowels every time they start to fill up. That’s why you never see a toilet aboard a starship, and why only the most oblique references are made to “waste extraction.”

But… this is just plain *silly*, isn’t it? “Waste extraction” was only ever mentioned in DS9, and only on a few occasions. There are few direct depictions of toilets in Star Trek, but there are references to them. Kirk sits on a toilet (clothed) in The Final Frontier, and Boimler says he dropped his tricorder in the toilet in Lower Decks. If we count non-canon sources, like starship blueprints, toilet facilities can be seen on a few different 23rd and 24th Century vessels, too. There are types of toilet today that don’t use water or a flushing system, and it’s conceivable that, in the future, refinements or brand-new designs could have been invented. Considering the energy cost, the number of transporters required, and the constant need to be in transporter range… I can’t see this being realistic. A fun, jokey idea? Sure. But something to take seriously? No!

Theory #5:
The USS Riker (from Starfleet Academy) is crewed entirely by Will Riker’s descendants.

(Cropped) still frame from Star Trek: Starfleet Academy S1 showing a Federation fleet.
One of these ships (probably the one on the far left) is the USS Riker.

The USS Riker has (at time of writing) appeared in one episode of Starfleet Academy – a blink-and-you’ll-miss-it cameo in Vox in Excelso. Someone online suggested that the Riker’s entire crew are the descendants of TNG’s Will Riker – famous, somewhat, for his womanising ways and romantic liaisons with a variety of different characters across the show’s seven-season run. Riker would later settle down with Deanna Troi, as we saw in Picard, and had two children – only one of whom survived to the dawn of the 25th Century.

But could Riker’s many flings and one-night stands across The Next Generation have led to more… offspring? This theory says so! And while I think it’s a cute joke within the fandom at the expense of how Riker was sometimes written, I don’t think it has an ounce of actual merit. Firstly, we don’t even know for sure that the USS Riker is named for *William* Riker and not some hypothetical other character. Riker’s father, Kyle, also worked for the Federation, the transporter clone known as Thomas may have survived the Dominion War, and Riker’s daughter may also have gone on to achieve something significant, just to give three examples of characters we know to exist. So… this cameo was cute, and appreciated by this old TNG fan. But the idea of a ship crewed entirely by the descendants of Riker’s various liaisons? Silly!

Theory #6:
Discord (from My Little Pony: Friendship is Magic) is actually Q.

Still frame from My Little Pony: FiM S6 showing Discord.
Discord.

We could’ve done an entire article on *just* theories involving crossovers with other franchises, I guess! But this one really does make me smile, because it’s just so silly. I concede that Q and Discord have some pretty obvious similarities: their personalities, their penchant for trickery, and the fact that they’re both ancient beings who form a bond with a mortal protagonist. But c’mon, guys… these are two completely different franchises with very little in common, totally different target audiences, and which are owned by two competing corporations.

John de Lancie portrays both characters, which is where this idea seems to have originated, but that’s really as far as it can go. The same voice actor has found himself somewhat typecast into playing a role which may have been directly inspired by his earlier character. That’s it. Q can’t exist in a franchise where… Q doesn’t exist. It’s a fun head-canon, I guess, if you’re a fan of both universes. But there’s no way it can be anything more than that.

Theory #7:
Benny Russell is real, and Gene Roddenberry stole Star Trek from him.

Still frame from Star Trek: DS9 showing Sisko seeing Benny Russell.
Sisko sees a reflection of Benny Russell.

There are a few variants of this theory. Some posit that, in-universe, the episode Far Beyond the Stars suggests that Star Trek as a whole exists as a fictional creation. I don’t agree with that at all (it’s always seemed logical, to me, that Benny Russell is a vision from the Prophets and nothing more), but I don’t, like, viscerally *object* to fans subscribing to that idea or exploring it. But I have seen fans propose – I *hope* entirely in jest – that there was a real Benny Russell once upon a time, and Gene Roddenberry either got the idea for Star Trek from him… or stole it.

If this is a total joke, which I believe it is, then… I mean, sure. Humour is subjective, and just because I don’t personally find it all that funny… I’m not the joke police. I can’t imagine any Star Trek fan taking this idea seriously, though, because it implies that not only did Gene Roddenberry steal these stories and this world-building, but then the DS9 writers – who must’ve known or been in on it – created a fictionalised version of Benny Russell as a character in their show… for… reasons? As a “confession?” A fun joke, maybe, but not something to take seriously.

Theory #8:
Saavik and/or Tuvok are transgender (because of Vulcan naming customs).

Saavik and Tuvok.

In The Original Series, every named Vulcan we met had a name beginning with S if they were male or T if they were female. But then, in The Wrath of Khan, we met Saavik – the first female Vulcan whose name begins with an S. Cue the fan theories! In short, this theory posits that, because of Vulcan naming conventions that were established in TOS, Saavik and Tuvok “must” be transgender. Saavik would be a trans woman and Tuvok a trans man.

Setting aside the silly premise for a moment, let’s think about this. There are some transgender folks who keep their birth name after transitioning, but it’s more common in the trans community to choose a name more befitting of one’s true gender. For Saavik and Tuvok to keep their deadnames wouldn’t make a lot of sense. Then there’s the fact that there’s absolutely no trans storytelling for either character… at all. In a way, you might say that’s great – that the Federation just accepts everyone and doesn’t make a big deal of it. But for a writer to introduce a character who is intended to be trans and then make no effort to tell a single trans or trans-adjacent story with them? And for fans to have to infer, years after the stories were first told, that these characters are meant to be trans? We’re hitting “Harry Potter” levels of fake inclusivity. If you find something relatable in Tuvok or Saavik as a trans person, I don’t wanna take that away from you. But it’s not how I read either character, and there are other explanations for their names.

Theory #9:
Star Trek V: The Final Frontier didn’t happen; it’s all just Kirk’s bad dream.

Did it really happen?

Have you ever taken a creative writing class? One of the first things the teacher warns you about is the importance of avoiding tired narrative clichés… like “but it was all just a dream.” And to me, that’s how this fan theory comes across. I get that not everyone likes The Final Frontier; I personally rank it as one of the lesser Star Trek films, too. But just because it isn’t popular… that doesn’t mean its events can be scrubbed from canon altogether. Not to mention that the film does genuinely have redeeming features and moments of characterisation (like Kirk, Spock, and McCoy camping) that I wouldn’t want to lose.

This theory hinges on Kirk’s starring role, and the fact that some of his worst fears seem to come true. Sybok’s presence (and Spock never having mentioned him) seems to threaten their special bond. His ship is stolen from him. Members of his own crew turn against him. And there are discrepancies, like the number of decks the Enterprise-A seems to have, or the “Galaxy-class” feel to the ship (caused by recycling sets from The Next Generation). But to me, this one feels like wishful thinking at best… or clutching at the tiniest of straws at worst.

Theory #10:
Nick Locarno and Tom Paris are the same person.

Promo photo for Star Trek: Voyager showing Tom Paris.
Tom Paris… or should that be Nick Locarno?

I think it’s safe to say that Lower Decks has debunked this one (though I still need to get caught up on that show!) But before Locarno made a return to Star Trek, fans speculated that “Nick Locarno” was actually a pseudonym adopted by Tom Paris prior to enrolling in Starfleet Academy. The theory went that Paris wanted to keep his connection to his father (who is a senior officer) a secret – either to be judged on his own merits, or for some other reason.

There are similarities between Locarno and Paris, besides the obvious point that both characters were played by Robert Duncan McNeill. They’re both able pilots, they both have a cocky or arrogant streak, and both have an ambivalent relationship with the Federation and its rules. On the production side of things, it’s long been rumoured that Voyager’s creators wanted to use Nick Locarno, but were concerned about having to pay royalties to the writer of The Next Generation episode in which he originated, so a new, very similar character was created. A photo of McNeill in his role as Locarno can be briefly seen in Voyager, representing a younger Tom Paris in his father’s office. So there’s merit to this in theory… but Lower Decks has completely debunked it by now. And if it were true, I’d have expected Paris to have said so, or for it to have been noted by Janeway early on in the series. The “Locarno” persona might’ve worked for a while, but the scandal would surely have blown his cover, and his identity would be common knowledge by the time of Voyager – at least among senior officers.

Theory #11:
Section 31 isn’t a real Federation organisation – it’s a criminal syndicate pretending to be one.

Still frame from Star Trek: Section 31 showing four main characters.
Section 31: Federation black-ops division or crime syndicate?

The way Section 31 has been depicted in Star Trek has fluctuated a lot. There’s been the clandestine, shadowy agency we encountered in DS9 and later in Enterprise. Then there’s the out-in-the-open branch of Starfleet Intelligence from Discovery. And finally, the “rag-tag gang of misfits” from the TV movie. But one thing that has remained consistent in Section 31 is that the people involved are all Federation die-hards doing things they believe to be in the Federation’s best interests… even as they answer to no one and wield almost unfathomable power.

I can see a world in which a criminal syndicate would side with Starfleet to help prevent, say, the Federation’s total conquest by the Dominion. Or in which Starfleet would make deals with shady crime lords to acquire some kind of biological weapon when faced with an existential crisis. And I can even see a world where a clever criminal would *claim* to be from a government agency or black-ops division as a tactic. But do any of those things apply to Section 31? I would argue no. The closest Section 31 has come to that kind of presentation came in the TV movie, but even then, it was clear that Starfleet was involved – albeit that the mission was still off-the-record. So this idea is simply debunked by what we’ve seen on screen – as fun as it might seem.

Theory #12:
Jean-Luc Picard is Wesley Crusher’s biological father (and he treats him the way he does out of a sense of guilt or obligation).

Still frame from Star Trek: TNG S1, showing Picard, Dr Crusher, and Wesley.
Picard with Wesley on the bridge of the Enterprise-D.

Sometimes you come across a theory – even one that’s been doing the rounds for years – and you just feel… gobsmacked. I simply don’t read Picard and Wesley’s relationship in this way, and any paternal feelings Picard has for the younger Crusher is pretty clearly explained within the context of the show as stemming from his close friendships with Jack and Beverly. Picard does come to appreciate Wesley’s talents, even giving him a role on the bridge of his ship… but not out of any kind of obligation or guilt – it’s in recognition of Wesley’s skills.

I will admit that Picard’s third season complicated my rebuttal somewhat, as we learned that Picard and Dr Crusher did have a child together, and that Dr Crusher kept this a secret. If she did it once, could she have done it years earlier? It could have been an interesting plotline in The Next Generation or even in Picard, if it had been handled well, but despite having some merit in theory, nothing in the show itself leads us to that conclusion. And such a complex story would require a very sensitive and well-written episode or arc, and I’m not sure it would’ve been handled well or been well-received by a large portion of the fanbase. So this one… it can be your head-canon, if you like, but it goes no further in my opinion!

Theory #13:
The Progenitors evolved into the Founders.

Still frame from Star Trek TNG showing an ancient alien/Progenitor.
A Progenitor in The Next Generation.

I don’t know if this theory came about because the same actress (Salome Jens) played both the ancient alien hologram in The Chase and the Female Changeling on DS9, but I suspect that has something to do with it! In any case, this theory posits that the “Progenitors,” as Discovery would later dub them, didn’t go extinct or disappear from the galaxy, but instead evolved to become the Founders of the Dominion. And on the surface, it doesn’t seem totally impossible. The Founders claim to have once been fully solid. And the Founders are capable of genetically engineering entire races. But if the Founders *were* descendants of the ancient aliens who seeded the entire galaxy with life… you’d think they might’ve mentioned it.

For me, that’s where this theory falls down. Something so monumental to who the Founders are – and most Founders seem to be almost ageless – would surely be preserved knowledge, handed down through the millions of years of their existence. Yet the Founders not only don’t bring this up, but they’re distrustful of any non-shapeshifters to the point of paranoia – not something you’d expect to see in the grandparents of the galaxy’s races. I don’t really like the way the Progenitors’ storyline went or what it says about the Star Trek galaxy, and perhaps that’s my own bias showing through when I rule out this theory. But I do believe that something so important would be known to the Founders, and it would be something they’d have at least tried to communicate in their various dealings with “solids.” Not to mention that, for a race that would need to be billions of years old… it’s weird that their technology got to a 24th Century level and apparently stayed there.

Theory #14:
Every film and episode that premiered after First Contact takes place in an alternate reality, due to the changes made to the timeline.

Still frame from Star Trek: First Contact showing the launch of the Phoenix.
The launch of the Phoenix.

Time travel is a pain in the arse, isn’t it? Time-loops, paradoxes… all of that. It’s very difficult to write a compelling time travel story and pull it off flawlessly – even more so in a long-running franchise with a timeline that has to be basically consistent from one episode to the next. This theory posits that the changes Picard and co. made in the 21st Century were so serious that the Star Trek franchise can essentially be divided into two alternate realities: pre- and post-First Contact stories.

I don’t know how to word this without using terms like “destiny” or “fate,” but I think the way we’re meant to read the events of First Contact is that the interventions by the Borg and Enterprise-E were always “meant” to happen; i.e. they happen in every timeline. That’s why there was no Department of Temporal Investigations inquiry, and no ramifications for Picard for meddling in the timeline. We could also ask why First Contact should be the divide – why not other time travel stories, like The City on the Edge of Forever, Assignment: Earth, Past Tense, or even Endgame. All of these made major changes to the timeline that, by the same logic this theory uses, could create an alternate reality.

Theory #15:
Discovery Seasons 3-5 didn’t happen – and what we saw are Pike’s imaginings during his convalescence on Talos IV.

Still frame from Star Trek: Discovery showing Saru, Tilly, and Burnham.
Tilly, Saru, and Burnham in the 32nd Century.

I don’t see how you could subscribe to this theory without also writing off Starfleet Academy, Section 31, and probably Strange New Worlds, too, as they’re all connected. But setting that aside… this theory reminds me more than a little of the Star Wars so-called “theory” that one or more of the sequel trilogy films is “about to be removed from canon!!1!” In short, it feels like a bit of a cope from folks who don’t like Discovery, the 32nd Century setting, and in particular, the Burn.

My personal view, by the way, is that – somehow – a future Star Trek production should find a way to gently push Discovery’s 32nd Century out of the prime timeline, partially because of how depressing the Burn is as a future destination, but also because of how it turns any potential future film or TV show into a de facto prequel to Discovery. But that isn’t the issue here: this theory posits that nothing we saw on screen in Discovery’s 32nd Century actually happened to begin with. That simply isn’t true; Discovery, Strange New Worlds, Section 31, and Starfleet Academy all coexist in the prime timeline. You can choose to disregard different parts of Star Trek from your personal head-canon; fans have been doing that for decades. Or you can choose not to tune in to any new shows set in that era. That’s totally okay. But this theory can be nothing more than head-canon, and a heavy hit of copium for folks who hate where Discovery went.

Theory #16:
Dr Zimmerman used the Professor Moriarty hologram when creating the EMH.

Still frame from Star Trek: Voyager showing Dr Zimmerman.
Dr Lewis Zimmerman.

In the episode Elementary, Dear Data, we saw the creation of a sentient, self-aware hologram: Professor Moriarty, Sherlock Holmes’ nemesis. Moriarty would later be re-activated and trapped in a holographic world, before apparently being transferred to Section 31’s Daystrom Station by the early 25th Century. As one of the first truly sentient holograms, it’s not impossible to think Starfleet would’ve wanted to study Moriarty, figuring out how a simple miscommunication with the Enterprise-D’s computer could lead to such an entity coming to exist.

This theory goes a lot further, though, suggesting that Dr Zimmerman – the creator of the EMH programme – used Moriarty in some way, either as a “template” or just to further his own research. And while nothing on-screen explicitly contradicts this idea, it’s just not something I think makes a ton of sense. Zimmerman is presented as egotistical and selfish, so the idea that he’d rely on someone else’s work instead of developing his own holograms doesn’t make a lot of sense. And it’s strongly implied in DS9 and Voyager that the EMH Mark I (i.e. the Doctor) had a long and difficult creation process, with some of Zimmerman’s more basic holograms coming first. So while the idea of Starfleet researching Moriarty makes sense, I don’t think Zimmerman being involved really does.

Theory #17:
Enterprise’s mysterious “Humanoid Figure” is Archer from the future, and he’s trying to sabotage his own earlier missions. For some reason.

Still frame from Star Trek: Enterprise showing Archer and the Humanoid Figure.
Archer meeting… himself?

This theory has the benefit of having been discussed by some of the original writers of Enterprise – with a suggestion that this was even a seriously-considered plot point for what would’ve been Season 5. But as we said above: time travel, time-loops, and paradoxes are really difficult to get right, and the idea of an older, jaded Archer somehow deciding that he wants to sabotage his own earlier mission and his own life… such a story would be difficult to write in a way that made sense, and it would be a challenge to pull it off successfully.

I’ve always interpreted the “Humanoid Figure” as simply being one of the leaders of a faction from the Temporal Cold War/Temporal Wars, though to be honest, I try not to think too hard about this element of Enterprise. Time travel stories just aren’t my favourites in Star Trek, and a significant portion of Enterprise was taken up by these kinds of plotlines. If the “Humanoid Figure” was meant to be Archer – which he wasn’t, at least not originally, as no identity was built into the character at first – it raises too many questions, and would realistically have needed a multi-episode arc. Given what we know of Archer’s future – his captaincy of the NX-01 and his later role in the founding and leadership of the Federation – this villainous turn (and his apparent acquiring of time travel tech) doesn’t make sense, and I struggle to see how a story could be written to take Archer from the textbook definition of a Starfleet captain to a man who tries (and fails) to sabotage… himself.

Theory #18:
We (the audience) are living in the timeline that ultimately becomes the Mirror Universe.

Still frame from Star Trek: Discovery S3 showing Terrans on the bridge.
Soldiers of the Terran Empire.

Do you ever read something and just think to yourself, “god, you were *so close* to understanding the point… but then you blew it?” The Mirror Universe is *intended* to be uncomfortably close to reality – any sci-fi dystopia is! That’s the point of the genre, and Star Trek’s Mirror Universe is meant to be a mirror (get it?) of our current society’s darkest impulses, moral failings, and inclination towards autocracy. That’s the entire point! It’s Star Trek showing us a dark reflection of ourselves to make us pause and think.

If you see elements of the Mirror Universe in today’s world, that isn’t because we’re in some dark timeline that Star Trek predicted… it’s because the stories were deliberately written that way to show us some of our own failings and societal problems. The point isn’t to fall into depression and pessimism, to say that we’re on a dark path and there’s nothing we can do but wait for the Terran Empire to emerge. We’re meant to look at these stories and say, “let’s do something about that. Let’s make changes for the better.” The Mirror Universe, with its pantomime-level overacting and one-dimensional baddies, has never been my cup of tea, and as a metaphor I think it’s almost too basic and too unserious. But in a way, that’s part of how it works: it’s storytelling by fable. The point was never that we’re locked into a dark path to the “bad outcome,” the point is that we have these dark impulses, but we can overcome them. Bad things can happen, and bad leaders can rise to power – but we can stop them.

Theory #19:
The Genesis Device and replicators are the same technology.

Still from Star Trek III showing the Genesis Planet.
The Genesis Planet.

This one made me smile. In a way, I like the idea of Starfleet looking at the Genesis Project and saying, “yeah, let’s not use it to terraform planets, let’s use it to make bowls of tomato soup.” It’s just kind of small-scale and silly. And it’s true that, out here in the real world, technological innovation often comes from unexpected places. An attempt to create a high-strength adhesive famously led to the weak glue used for post-it notes, for instance!

Star Trek works best when its technologies are deliberately kept vague. That allows for maximum wiggle-room when telling a story, and it also allows for head-canon like this to exist. I guess you could say that, based on what we know of both the Genesis Device and replicators, they both use subatomic particles to change one form of matter into another. But does that mean that one was developed from the other, or that Starfleet shut down Project Genesis only to use the same technology in a totally different way? I don’t see it.

Theory #20:
The entire Soong family are clones – which is why they all look the same.

Composite image of various Soong characters from Star Trek.
A family portrait…

This theory exists for one reason and one reason alone: every member of the Soong family that we’ve met is played by the same actor! Brent Spiner took on the role of Data’s creator in The Next Generation, and this was later expanded in Enterprise and Picard to include new ancestors and descendants of the Soong family. They all look the same because they’re all Brent Spiner. But could there be more to it than that?

Adam Soong, the earliest-known Soong ancestor, was interested in genetic engineering, so could he have cloned himself in the mid-21st Century, sometime after the events of Picard’s second season? I mean, it’s not *impossible*, I suppose. But we know in the prime timeline that genetic engineering has been outlawed, so the practice can’t have continued through the generations all the way to Altan Soong in the late 24th Century, surely.

Theory #21:
Worf has an incorrect (or incomplete) idea of what it means to be a Klingon, because he only learned about his culture from Federation books.

Worf is a Klingon… but he was raised from a young age by humans. That’s a core part of his character background, and having lived away from his homeworld and his people, Worf can feel torn between his loyalties to Starfleet and to the Klingons. But does Worf truly know what being a Klingon means, having only learned about his culture from books? Some fans seem to think he doesn’t, arguing that it explains why Worf seems to lack the famous Klingon sense of humour, being very dour and serious almost all of the time. Others have even suggested that Worf might have a form of “Klingon autism.”

There is the kernel of an interesting idea here, and I think it could’ve been fun to put Worf into a Klingon story as a “fish out of water,” or better, as someone who *thinks* they know everything… until they’re confronted by people who’ve been immersed in that culture from day one. But Star Trek never went down that route, and there are other examples of stoic Klingons who share some of Worf’s traits. It’s an interesting theory, in some ways, but we’ve spent so much time with Worf over the years, and he’s had so many encounters with a huge number of Klingons, that if this theory were even close to true… we’d have seen something more concrete.

Theory #22:
Romulans are the “true” Vulcans, and Vulcans are the ones who left.

Still frame from Star Trek: Strange New Worlds showing a Romulan commander.
A 23rd Century Romulan.

This just flat-out isn’t true. It’s established multiple times in Star Trek that the Romulans were the ones who left their homeworld behind after rejecting the Vulcans’ moves to embrace logic and purge their emotions. Now, if this theory had said that Romulan culture is the original Vulcan culture, I guess we could have more of a conversation, because there’s a way to read the Romulan-Vulcan split that would say the Romulans preserved a pre-Surak, pre-logic culture that the Vulcans may have possessed. But that’s never been confirmed on screen.

What I think would be a way more interesting theory is this: the Vulcans have *always* known the Romulans’ true identity, but chose not to share that with Earth and humanity, perhaps out of a sense of shame or fear. I think there’s a great case to be made that the Vulcans either kept track of the Romulans or else were able to scan their bio-signs, analyse their language, or something after re-encountering them. It’s always seemed likely to me that Vulcan leadership, at least, was aware of their shared history – even if individuals like Spock may not have been. But this idea that the Vulcans are the offshoot… it just doesn’t line up with what we’ve seen on screen in many different stories.

Theory #23:
There is no “Q Continuum;” there’s only one Q, and after billions of years of isolation and loneliness, he’s developed some kind of multiple personality disorder.

Still frame from Star Trek Picard S2 showing Q.
Q in Star Trek: Picard.

Again, we have a theory that directly contradicts things we’ve seen on screen. As far back as The Next Generation, Q was confirmed to be just one member of a species, and we even met other Q in the show. I guess this theory would also propose that all of those individuals were the same Q, but that doesn’t make a lot of sense, does it? Nor does the idea of a Q civil war, as seen in Voyager, or one member of the Continuum committing suicide. If we’d only met Q a few times, and never seen other members of his race, I’d at least have to concede that this one was plausible. But having met dozens of other Q and literally visited the Continuum itself… I think there’s more than enough evidence to dump this one in the “debunked” pile.

There are mysteries associated with Q, though – not least what became of the familiar John de Lancie character after his apparent “death” in Picard’s second season. I just don’t see this as being a plausible theory, or even something mysterious at all. The Q Continuum exists, other Q exist, and trying to overwrite that would mean dozens of stories would be adversely affected. It’s an interesting thought, for sure, but one that just feels thoroughly debunked by what we see on screen.

Theory #24:
The species that abandoned Armus were the Founders.

Still frame from Star Trek: TNG S1 showing Armus.
Armus.

This theory obviously comes from Armus and the Founders both existing in a liquid state, and I can see why it might seem plausible on the surface. But there are two pretty big issues which, in my view, render it null and void. Firstly, Armus lives in the Alpha (or Beta) Quadrant, whereas the Founders and Dominion are native to the Gamma Quadrant. Without access to the Wormhole (which the Founders canonically did not know about until they met the Federation), that’s a decades- or centuries-long journey.

Secondly, and perhaps most importantly, if the point of creating and abandoning Armus was for the Founders to shed their “skin of evil,” and to leave all of their negative traits and qualities behind… it didn’t exactly work, did it? The Founders are paranoid, hateful, and view themselves as superior to most other forms of life. So… how is Armus alone the sum total of all of their negative qualities? Between that and the distances involved, I have to say that I don’t find this one to be plausible. The fact that both the Founders and Armus are liquid doesn’t do enough to outweigh that.

Theory #25:
Apparent discrepancies between The Original Series and the rest of Star Trek are because TOS is a holonovel being viewed from the 24th Century.

Kirk, Spock, and Dr McCoy.

I admire the lengths some fans are willing to go to in order to smooth out inconsistencies in Star Trek’s canon. A similar theory states that These Are The Voyages didn’t happen as shown, because it was an exaggerated or misremembered holo-programme. But in this case… I mean, firstly there’s just no evidence at all that a single part of TOS is a holo-programme. Then there are episodes like Trials and Tribble-ations, which very clearly show that TOS and the 24th Century share a setting. And while there can be inconsistencies within Star Trek’s canon, I’m not even convinced at this point that the line should be drawn between TOS and the rest of the franchise. Why not between, say, Voyager’s finale and everything that came after?

This will sound unsatisfying, especially for folks who love to theorise – and I get that, believe me. But the plain and simple fact is that these discrepancies and inconsistencies exist because Star Trek is a long-running franchise, and these are stories. Sometimes, a new story seems to overwrite or retcon something, or makes a change that’s inconsistent with what came before. While I have argued in the past that internal consistency is important, I’m also not a stickler for the tiniest minutiae of canon, and I believe there’s enough wiggle-room in Star Trek for all of the various parts of its universe to coexist in a single setting.

So that’s it… for now!

We’re flying too close to the sun…

I hope this has been fun. Twenty-five theories was a lot, but at the same time… I feel there’s more to this idea. So if your favourite bad theory didn’t make the cut, stay tuned. I may revisit this concept in the future, if I can find more fan theories to pick on.

As I said at the beginning, this was meant to be a bit of fun, and not something to get too wound up or upset over. While I don’t personally subscribe to any of these theories – for reasons I’ve tried to explain – I found all of them to be interesting, and I don’t want to dent anyone’s passion for Star Trek. I’m a theory-crafter myself, so I respect and appreciate other folks putting their theories out there to be discussed.

I’ve got a few more ideas for articles and columns as Star Trek’s huge sixtieth anniversary year rolls on. How many TV shows and franchises can say they’ve made it this far, eh? Not many, that’s for sure! It’s a testament to how amazing this franchise is that so many years later, people like us are still discussing and debating every aspect of Star Trek, and still enjoy getting lost in this fantastic setting.

So please stick around throughout 2026 for more pieces celebrating all things Star Trek! Next month, I daresay I’ll be writing a review of Starfleet Academy’s first season. And I’m still hopeful we’ll see Strange New Worlds before the year is out. And there are other theories, discussions, and episode re-watches to get into, too.

Thanks for tuning in this time… and Live Long and Prosper, friends!

Star Trek: Discovery theories – weeks 1-2

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-4, Star Trek: Picard Season 1, and for other iterations of the Star Trek franchise.

Now that all of the international broadcasting nonsense is out of the way, let’s get back into my weekly Discovery theory updates! We only missed one week, and there’s still a ton of speculating to be done about the story of Season 4, the gravitational anomaly, and what might become of some of our favourite characters.

If you’re new to my weekly theory updates for Discovery Season 4, here’s how the format works: after every episode I go back to my theory list. I cross off theories that have been debunked, celebrate any that appear to have been confirmed, update any that have seen progression, and add any new theories that the most recent episode has spawned. There will be some theories that, for whatever reason, the most recent episode didn’t advance in any way, so those will simply be restated to keep the list up-to-date and in one place!

I wrote up all of my pre-season theories into one list a couple of weeks ago, so this time we’ve already got two confirmations to take a look at before we jump into the main list.

Confirmed theory #1: The Spore Drive will be rolled out to more ships.

Book in Discovery’s Spore Drive cube.

Finally! After the revelation in the Season 3 finale that Book – and potentially anyone else with similar empathic abilities – could control the Spore Drive, the last hurdle in the way of it being rolled out to other Starfleet ships had been surmounted. It finally feels like Discovery is on the cusp of finding another use for what had been one of the most controversial technologies introduced in the series.

In Kobayashi Maru this was almost treated as a throwaway line, so I wouldn’t blame you if you missed it, but President Rillak confirmed that a “next-generation” Spore Drive is being developed by Starfleet as part of the Federation’s plans to rebuild and expand. It wasn’t stated on screen, but I wonder if the USS Voyager-J might be fitted with a Spore Drive as part of its retrofit; the vessel was in spacedock, after all.

The USS Discovery makes a Spore Drive jump.

I’d been hoping that the series would go down this road for a while. Moving forward in time to the 32nd Century means there are no “canon purist” arguments in favour of abandoning the Spore Drive, keeping it a secret, or ensuring that only the USS Discovery could use it. And the events of the Season 3 finale seemed deliberately designed to create an easy way to expand the Spore Drive to more ships – perhaps even paving the way for future Star Trek productions in this era.

We don’t yet know what the implications will be of Kwejian’s destruction on Starfleet’s plans. It was implied in the Season 3 finale that anyone with empathic abilities could use the Spore Drive, not only Kwejian natives, so the loss of Kwejian and most of its population shouldn’t mean that the Spore Drive expansion has to be abandoned. It might be possible for Betazoids, Deltans, or even Vulcans to train to become Spore Drive navigators.

Confirmed theory #2: A new character joined the main cast.

A new name has been spotted in the opening credits!

Following the departures of Nhan and Georgiou, it felt like there was definitely scope to either promote a recurring character to the main cast or create at least one new one! We’ve met President Rillak, who seems like she’ll become a recurring character, but the one who’s been promoted to join the main cast is Blu del Barrio’s character of Adira.

Adira makes a great addition to Discovery’s main cast of characters, occupying a similar role to Tilly in Season 1 in particular. As Tilly has undergone significant character growth across the show’s first three seasons, there was scope to bring someone brand-new aboard the ship, and having that person be someone young and eager is a positive thing. Adira is not only involved in their own storyline with Gray and Dr Culber, but also as a scientist can work with Stamets, Tilly, Saru, and Captain Burnham. I think Adira has the potential to be a versatile character in whatever stories lie ahead.

My original version of this theory centred around the question of Captain Burnham’s first officer. Now that we know that role has gone to Saru, it seems as though the main and recurring characters for this season are set.

So those theories were confirmed. Now we’ll take a look at some new theories and a few updated theories.

Theory #1: President Rillak knows what the anomaly is… and may be responsible for its creation.

President Rillak in Kobayashi Maru.

This ties into a broader point that we’ll be considering from several angles: the possibility that the gravitational anomaly is not a natural phenomenon. If the anomaly is artificial in nature, the question of who is responsible for its creation crops up. It could be a weapon deployed by another faction, of course, but it could also be a Federation creation – perhaps a weapon designed to defend against the Borg, a rogue experiment to try and prevent a second Burn, or something else entirely.

If that’s the case, President Rillak almost certainly knows more about the anomaly than she’s willing to say right now. Perhaps she’s hoping that it won’t be what she fears it is, or perhaps she’s trying to cover her own back – Captain Burnham did go out of her way to describe her as a “politician,” after all.

Does President Rillak know more about the anomaly than she’s saying?

President Rillak is a character with depth, not simply an “evil admiral” character trope. But it wouldn’t be the first time that Discovery has presented us with a fairly hard-line character in a position of authority who turns out to be concealing a dark secret.

As the head of the Federation, President Rillak is committed to doing whatever it takes to preserve the organisation. The anomaly may have been part of those plans… somehow. If she isn’t responsible for its creation directly, she may still know what it is if a past Federation President signed off on its creation. She may be covering up that secret on behalf of the Federation.

Theory #2: Captain Burnham and/or the Red Angel time travel suits from Season 2 are connected to the anomaly.

Captain Burnham.

Though we did see some moves away from Discovery’s laser-focus on Michael Burnham in Season 3, the show has put her front-and-centre in all of its main storylines so far. Season 2’s Red Angel storyline was connected to Burnham in a major way, and I wonder if Burnham might similarly have some kind of connection to the anomaly that she’s currently unaware of.

Perhaps the Red Angel suit, which Burnham sent back in time in the Season 3 premiere, malfunctioned somehow, and its powerful wormhole-creating technology gave rise to the gravitational anomaly. If the Red Angel suit completed its journey back to the 23rd Century, the anomaly may have had centuries to grow and expand unchecked.

This was the last we saw of the Red Angel suit back at the beginning of Season 3.

I’m not sure that this one is particularly likely, but as I said last year about a possible Burnham connection to the Burn, not only does Discovery kind of have a precedent for telling this kind of story, but there would also be something very dramatic about this revelation. In this case, Burnham would be indirectly and unknowingly responsible for creating something devastatingly damaging. How would she react to that, and how would Book react given what’s just happened to Kwejian?

If time travel is involved, perhaps a future Captain Burnham or a parallel universe Captain Burnham could be responsible for the anomaly’s creation – either intentionally or not.

Theory #3: Gray’s transfer to a new body won’t be simple.

A holographic representation of Gray’s synthetic body.

I adored the scene with Gray, Adira, and Dr Culber in Anomaly. As someone who’s struggled to come to terms with my own gender identity and my gender expression, it was so deeply relatable to see Gray “customising” his new body. But also included in that scene was a line from Dr Culber about how the “Soong method” used to transfer consciousness into a synthetic form has a very low success rate.

I suspect that line was included as a kind of pre-emptive plot hole plug that will have nothing to do with Gray! If the Soong method was said to work every time, then it would be very difficult to kill off any Star Trek characters from the 25th Century onwards, because fans would rightly ask “why didn’t they transfer to a synth body?” So I suspect that’s why the line was included.

Admiral Picard had his consciousness transferred to a synthetic body in the finale of Picard Season 1.

However, it felt a little ominous for poor Gray. It was great to see that Adira, Dr Culber, and others had been working hard to help Gray become seen again after the events of Season 3, and I have no doubt that somehow we’ll see Gray in a physical body before the season is over. But we’re only two episodes in at time of writing – will it really happen so quickly, and so seemingly simply?

I’m not convinced of that yet! There are many things that could go wrong, delay the transfer, or prevent it entirely. And there are an unlimited number of technobabble explanations for finding a new way to give Gray a body! So let’s see what happens – but I wonder if this storyline might have a few twists and turns along the way.

Theory #4: Book will find Kyheem and Leto inside the gravitational anomaly.

Book with Leto and Kyheem shortly before the destruction of Kwejian.

In Star Trek: Generations, Captain Picard encountered Captain Kirk inside the Nexus – despite Kirk being declared “dead” after the Enterprise-B encountered the energy ribbon. We don’t know what the gravitational anomaly is yet; one of my very early pre-season theories involved the Nexus, but that seems to be debunked already! However, the anomaly’s mysterious nature raises the faint possibility that at least some of those it appears to have “killed” may not be as dead as they first appear.

This theory is, I freely admit, a bit of a long-shot. And it hinges on a fundamental question underlying the story of the season: is there more to the gravitational anomaly than meets the eye? If the anomaly is just an extreme example of space weather, flitting through Federation space destroying anything unfortunate enough to be in its way, then probably everyone on Kwejian is dead. But if the anomaly harbours some kind of gateway, wormhole, portal, time vortex, or any of the other Star Trek-y technobabble phenomena that we’ve seen across the franchise’s history, then it’s possible that at least some of the folks on Kwejian found themselves transported to whatever realm lies inside of the anomaly.

Theory #5: The anomaly is a sentient life-form.

Could the anomaly be similar to V’Ger?

“It was only trying to communicate!” has become a Star Trek cliché, often used to describe how the seemingly-aggressive actions of an alien life-form are actually something innocuous. Perhaps the same is true of the gravitational anomaly: at its core is a life form, perhaps one not dissimilar to the Sphere seen in Season 2, and it’s on its own mission of exploration.

V’Ger from The Motion Picture is an interesting comparison. Like the gravitational anomaly, V’Ger was massive in size, capable of destroying space stations, fleets of ships, and even threatening to destroy entire planets. When Admiral Kirk and the crew of the Enterprise were able to figure out V’Ger, however, they found a life-form at its core, one which was just as curious to learn and grow as they were.

Theory #6: Saru will be given the captaincy of the USS Voyager-J.

The USS Voyager-J.

Saru’s future was briefly discussed before he offered to serve as Captain Burnham’s first officer. He has already been offered a command of his own, so Starfleet clearly values his command abilities and experience. President Rillak was seen to be assessing Captain Burnham’s suitability for the captaincy of the USS Voyager-J in Kobayashi Maru… and she mentioned having a shortlist of candidates. Could Saru be on her list?

At time of writing, a fifth season of Discovery hasn’t been officially confirmed. But if the show is to run for another season – or more – the question of Saru’s role comes up. It would be possible to work out a way to keep him on board as first officer for longer than one season, and in many ways I think that’s something fans would want to see. But at the same time, from an in-universe point of view, it kind of makes sense for Starfleet to use its experienced captains where possible.

Captain Saru.

Several of the qualities that President Rillak said she was looking for in a potential captain seem to apply to Saru. He’s more level-headed, less likely to put himself in a dangerous situation, and more inclined to think of the big picture. He has a weakness when it comes to Kaminar, as we saw toward the end of Season 3, but generally speaking he isn’t someone who lets his emotions get the better of him. His wisdom and calm demeanour could be valuable in the captain’s chair of the Federation flagship.

If Saru did depart Discovery in a future episode or season, could that perhaps set the stage for Star Trek: Saru… or perhaps Star Trek: Voyager-J? That’s a very interesting possibility! One element of Season 3 that I felt didn’t really get as much attention as it might’ve was that Saru was the Star Trek franchise’s first non-human captain (in a leading role). There’s perhaps scope to follow him on another adventure sometime in the future.

Theory #7: The gravitational anomaly is a superweapon.

The USS Discovery approaching the anomaly in the second Season 4 trailer.

We touched on this theory above when we considered the Federation’s possible complicity in the creation of the gravitational anomaly, but there are many other ways such a story could pan out. The anomaly’s unpredictable nature, as noted by Tilly and Saru at the end of Anomaly, could imply that there’s an intelligence at work, perhaps dictating the anomaly’s moves. This could be the anomaly itself as suggested above, but it could also be the case that the anomaly is being controlled or manipulated by something or someone externally.

If the anomaly turns out not to be a natural phenomenon, and is indeed deliberately targetting the Federation, who might the possible culprits be? And what would be the purpose behind attacking the Federation in this manner? If it’s the precursor to an invasion, perhaps later in the season we’ll see whoever is responsible making their next move.

Theory #7a: The Borg are responsible.

A Borg drone seen in The Next Generation.

We don’t know whether the Borg Collective still exists in the 32nd Century; it hasn’t even been mentioned since the USS Discovery’s arrival. However, out of all of the factions in Star Trek, few seem capable of creating a weapon on the scale of the gravitational anomaly. This wouldn’t be in line with the Borg’s usual modus operandi, as they prefer to assimilate rather than attack from afar. But a lot may have changed in the centuries since we last encountered them, meaning this could be the opening salvo of a Borg attack… or the last gasp of a dying Collective.

Theory #7b: The super-synths from Picard Season 1 are responsible.

This is all we really saw of the super-synths.

We still don’t know very much about the super-synths that Soji and Sutra attempted to contact in the Season 1 finale of Star Trek: Picard. Other than claiming to offer support and help to synthetic life, what are their goals and motivations? Was their offer even genuine, or was it a trap? The mechanical tentacles glimpsed in Picard Season 1 looked terrifying! Moreover, we know that the super-synths have the technology to move stars – something only possible with an advanced understanding of gravity. Creating a stable 8-star octonary system is an incredible technological and gravitational feat, so they have precedent of a sort when it comes to working with gravity.

Theory #7c: The Kelvan Empire is responsible.

Rojan, a representative of the Kelvan Empire.

This one might seem to come completely out of the blue! In The Original Series, Captain Kirk met representatives of the Kelvan Empire, a faction originally from the Andromeda galaxy. Seeking a new home, a Kelvan scouting party had reached the Milky Way and were looking for worlds to conquer. Kirk would ultimately dispatch an unmanned starship offering to help the Kelvan Empire find new worlds to settle – but what if his offer was rejected? Given the vast distances involved, the timelines kind of line up for the Kelvan Empire to return to the Milky Way.

Theory #7d: The Sphere-Builders from Enterprise are responsible.

A Sphere-Builder seen in Enterprise.

A defeated faction in one of the Temporal Wars, the Sphere-Builders initially hoped to convert a large swathe of the Alpha Quadrant to match their native extradimensional realm, and constructed a number of large space stations known as Spheres to facilitate this transformation. Crewman Daniels would tell Captain Archer that the Sphere-Builders were defeated in the 26th Century, but could they have since rebuilt? The gravitational anomaly isn’t necessarily the same as what they were trying to do with the Spheres, but they’re one of the few factions in Star Trek that might be capable of creating a weapon on this scale.

So those theories were new or saw some advancement in the first two episodes of the season.

To keep these theory posts as uncomplicated as possible, I like to keep all of my theories in one place. So below you’ll find all of my other Season 4 theories. These weren’t debunked or confirmed in the first two episodes, and indeed saw no real movement at all. They remain in play, though.

Theory #8: A major character will be killed.

A Starfleet coffin draped with the Federation flag as seen in Deep Space Nine.

Season 3 saw a couple of major departures: Mirror Georgiou entered the Guardian of Forever’s portal, and Nhan remained behind aboard the USS Tikhov. Yet despite the dangers the crew faced as they navigated the 32nd Century, battled the Emerald Chain, and figured out the mysteries of the Burn and the Verubin Nebula, only one ally – Ryn – lost their life.

Killing off a character can be an excellent way to communicate the stakes involved if it happens at a relatively early stage. It can also be a storyline that brings a lot of emotion, as we have to say goodbye to a beloved member of the crew.

Dr McCoy and Sulu playing dead in The Wrath of Khan.

In short, I think there are plenty of reasons on the production side why killing off a major character could make sense in Season 4. Discovery has seen a number of characters leave the series – far more than any past Star Trek show, in fact – but the series’ death toll is still relatively low when compared to many other modern television shows.

There are also a couple of characters who feel in danger for different reasons. For a full breakdown of which characters I think might be on the proverbial chopping block, check out my list of “death predictions” by clicking or tapping here.

Theory #9: There will be a character crossover from a past iteration of Star Trek.

Voyager’s Doctor is a contender!

Yes, I’m officially bringing this theory back! This is one that I doggedly clung to for all of Season 3, and while it arguably kind of happened with the Guardian of Forever, that wasn’t really what I meant.

The show’s 32nd Century setting has shot Captain Burnham and the crew far beyond anything in Star Trek’s established canon, and that should mean that practically everyone we remember from other Star Trek shows won’t be around any longer. But this is Star Trek – with some creatively-written technobabble, practically any major character could have survived all the way through to the 32nd Century!

Could Sutra still be alive in the 32nd Century?

It’s also possible for Captain Burnham to discover the logs of a long-dead officer; someone we as the audience would be familiar with. While this would be less of a “crossover” than if a character from the past could be physically present, it would still be a lot of fun to see!

There are a handful of characters who could have survived to the 32nd Century based on what we know about them from past iterations of the franchise. Included in this category would be people like Soji, Voyager’s Doctor, and a few others. But as we’ve seen in episodes like Relics and even the film Generations, all it would take to make a big crossover happen is some kind of temporal anomaly, stasis field, or other technobabble!

Theory #10: Burnham may not remain in the captain’s chair.

Michael Burnham in the captain’s chair in a promotional image for Season 4.

This is a controversial one, so let me just say up front that I’m neither in favour of this theory nor opposed to it – I just think it’s a possibility. As things stand, Discovery has had four different captains across its four seasons. One of the show’s unique points of interest within Star Trek’s broader canon are the very different ways in which these individual captains commanded the ship and crew.

It’s got to be considered at least a possibility, then, that the show will continue this trend. This doesn’t mean Captain Burnham will be killed off; I’d actually argue she’s pretty safe. But there are many different routes to her potentially leaving the ship, such as a desire for freedom that we saw in Season 3, or even perhaps taking up a new, more senior role within Starfleet.

Captain Burnham in Anomaly.

If this theory were to come to pass, it would be something I’d expect to see at the very end of the season. Even if Burnham seems 100% committed to her new role as captain, I don’t think it’s a theory we can definitively rule out.

It’s worth mentioning that at time of writing Discovery hasn’t been officially renewed for a fifth season – so all this talk of who’ll be in the captain’s chair by then could be moot! And of course this theory has a very strong counter-argument: that Discovery’s main story arc across its first three seasons can be read as Burnham’s ascent to the captain’s chair.

Theory #11: Kovich works for Section 31.

Kovich in Season 3.

This is another Season 3 theory that I’m choosing to bring back! The question of who Kovich is and what role he played in Starfleet and the Federation was left open at the end of Season 3, and we know that the character will return in some capacity. As someone who seemed to talk around the issue at hand and not reveal everything he knew, Kovich strikes me as potentially being a Section 31 operative – or even the head of the organisation.

We don’t know yet if the Section 31 series that was announced in 2019 will go ahead as planned. But if it does, there could potentially be a connection between Kovich and Georgiou that would tie the two shows together. Kovich is mysterious enough that his character could be taken in many different directions – but my money’s on Section 31.

Theory #12: The ban on time travel will be explained further.

Admiral Vance first told us of the ban on time travel.

This one is a hope as much as a theory right now! In short, the ban on time travel was introduced early in Season 3 primarily as a way for the writers and producers to avoid questions about why the 32nd Century was so different from how the far future had been depicted in earlier Star Trek productions, as well as to explain things like how the Burn was able to catch the Federation off-guard and why Georgiou couldn’t simply be sent back in time when she needed to.

But the ban itself raises some issues – the biggest one being the lack of detail on how it works and how something like this could possibly be enforced. As I said several times last season, it isn’t possible to just un-invent a technology so useful and powerful as time travel. Even just a few lines of dialogue going into a little more detail on the mechanisms involved in the ban would be really useful.

Theory #13: The Federation has flouted the ban on time travel.

HMS Bounty travels through time in Star Trek IV: The Voyage Home.

Sticking with the time travel ban, another theory I had last season was that the Federation – and Section 31 in particular – might have deliberately flouted the ban and failed to abide by the rules. Someone as straight-laced and committed to Starfleet ideals as Admiral Vance is highly unlikely to have sanctioned such a move, but someone like the shadowy Kovich (who we talked about a moment ago) might have. President Rillak could also be involved.

Obviously the bulk of the season’s story will deal with the gravitational anomaly. But there’s scope to either talk about the time travel ban in a standalone episode or even tie the two stories together – perhaps the anomaly has been unleashed as a result of unsanctioned time travel.

Theory #14: The story will connect with the Short Treks episode Calypso.

The USS Discovery seen in Calypso.

Despite a handful of moments in Season 3 which seemed to connect to Calypso, the story of the season overall ended up going in a very different direction. While we saw a couple of things that arguably did tie in to the Short Treks episode, major things like the USS Discovery undergoing a refit have actually moved the plot even further away.

It’s possible that Calypso will forever remain an outlier in Star Trek’s canon – an episode tied to a vision of Season 2 or Season 3 that was changed before it made it to screen. But earlier in Season 3 it felt like we were getting close to seeing how it could all be tied together – and I’m hopeful that Season 4 will find a way to do so.

Theory #15: The crew will have to defend the Verubin Nebula.

The dilithium planet at the centre of the Verubin Nebula.

The Federation is in a weakened state, and even if we see worlds like Ni’Var rejoin the organisation it’s still nowhere near as powerful as it once was. The Verubin Nebula is thus a very tempting target for anyone looking to gain an edge in a galaxy where dilithium is still in short supply. As the only known significant dilithium supply, whoever controls the Verubin Nebula will have a massive tactical advantage.

We can compare the Verubin Nebula to Deep Space Nine’s Bajoran wormhole in that respect – it’s a resource of huge strategic importance. Season 3 didn’t show us much about the makeup of the galaxy’s factions outside of the rump Federation and the Emerald Chain, but it’s got to be possible that factions like the Dominion, Klingon Empire, or even the Borg still exist and would want to seize the Verubin Nebula for themselves.

The USS Discovery arriving at the Verubin Nebula in Season 3.

Season 4 has teased a scientific puzzle – the gravitational anomaly. But that doesn’t mean there won’t be villains in play, and Discovery has introduced us to several compelling and interesting villains over its first three seasons.

To make a long theory short, it would begin to stretch credulity to think that everyone in the known galaxy would see the Federation rebuilding and having access to dilithium and not want to find out for themselves what’s going on. Once the Verubin Nebula’s existence becomes known, even if the Federation promises to share its bounty with all comers, it seems very likely that someone would want to take control of the dilithium supply for themselves.

Theory #16: Captain Burnham and the crew will encounter the Klingons.

The Klingons have been part of Discovery since the beginning.

By the late 24th Century the Federation and Klingons were firm friends, having been allied for a century and after fighting side-by-side against the Dominion. We don’t know if that alliance endured to the 32nd Century, but it’s certainly plausible to think that it did. The Klingons might even have joined the Federation at some point, and their violent warrior culture may have been significantly pacified.

One thing that could be very interesting to see is how the crew of the USS Discovery – almost all of whom are veterans of the Federation-Klingon war – would respond to that. They’ve worked alongside Klingons like L’Rell before, but many of them still see the Klingons as an old enemy. The story of overcoming that prejudice could mirror episodes like The Wounded from The Next Generation, and would be very interesting to see.

Theory #17: Some areas of the galaxy – such as the Delta Quadrant – avoided the worst effects of the Burn.

The USS Voyager was the first Federation starship to explore the Delta Quadrant.

It’s quite possible that Season 4 won’t revisit the Burn narrative in any detail. But one thing I’d be curious to see is the true extent of the disaster – did it reach all four quadrants of the galaxy equally, or did its effects fade out after a certain point? Michael Burnham discovered that the Burn had a point of origin, and that it radiated out from that point like ripples on the surface of water. Ripples eventually diminish, fading away the further they travel, and perhaps that’s true of the Burn as well. There could be whole areas of the galaxy that didn’t even notice the Burn – and maybe the ship and crew will visit one such region.

If the Delta Quadrant was left largely unscathed, for example, what might that mean for the likes of the Borg? It’s possible they aren’t even still around in the 32nd Century, but it’s also possible that they’ve had more than a century to expand and build up their forces while the Federation suffered.

Theory #18: The Guardian of Forever will be back.

Carl – the Guardian of Forever’s new persona.

Having reintroduced the Guardian of Forever in Season 3, I wouldn’t be at all surprised to see Discovery return to the Guardian’s planet in Season 4. The gravitational anomaly is something new and threatening, so it’s possible Captain Burnham might want to ask the Guardian for help or information.

The Guardian of Forever is also the only way we know of at present to travel through time – something that might be necessary if Season 4 makes an attempt to link up with Calypso in a big way. There are many reasons why Captain Burnham might want to revisit the Guardian, and it would be great to bring back actor Paul Guilfoyle, who played the Guardian’s humanoid avatar in Season 3.

So that’s it! Those are all of the theories I currently have in play.

Stay tuned for weekly updates to this list after new episodes air! I try very hard to publish my theory updates in between episodes so that nothing is out-of-date! Season 4 is off to an exciting start – and there are plenty of mysterious elements to get stuck into.
