Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-3 and the teaser trailer for Season 4. Further spoilers are present for the following: Star Trek: Picard Season 1, Star Trek: The Next Generation, Star Trek: Generations, Star Trek: Voyager, and Star Trek: Enterprise.
Star Trek’s First Contact Day virtual event has given us an awful lot to digest! We got teasers for Picard Season 2, Lower Decks Season 2, Discovery Season 4, and more details about Prodigy. If you missed the event, I wrote up my impressions of everything we saw, and you can find that article by clicking or tapping here.
This time, I want to look at the teaser for Discovery’s impending fourth season in more depth, and in particular start making some guesses about what may be going on! The teaser was barely ninety seconds long, and with the show at least six months away it may be futile to speculate about pretty much anything! But that hasn’t stopped me in the past, so let’s jump in!
My usual disclaimer applies: I don’t have any “insider information.” I’m not offering up these suggestions saying any are unequivocally true. This is nothing more than speculation from a fan – and a chance to spend some more time talking about Star Trek, which I absolutely adore.
In the run-up to Season 3 last year, I spent a lot of time speculating about the event that ultimately turned out to be the Burn. When we first heard its name I put together a list theorising a number of possible connections to past iterations of Star Trek – but as you know by now, none came to pass!
Discovery has had an on-off relationship with Star Trek’s broader canon. Season 1 sidestepped a lot of things, redesigning the Klingons, visiting the Mirror Universe years before Kirk’s first crossing, and fighting a major war. Season 2 tied itself much closer to canon, bringing in Captain Pike, Spock, and revisiting Talos IV. Season 3 shot forward into the future, and told a story that touched on past iterations of the franchise at points, but had an overall narrative that stood on its own two feet.
In short, trying to guess whether Season 4’s main storyline will be related to something we’ve seen in the past or not is a crapshoot. Maybe it will be, maybe it won’t. Regardless, if it’s going to be something brand-new then naturally the details become impossible to predict! So in this list I’m going to look at eight possibilities from Star Trek’s past that could explain what we saw in the teaser.
First of all, let’s explain what exactly we saw! Stamets described a “gravitational anomaly” that’s at least five light-years in diameter. This anomaly appears to be incredibly destructive, and if Burnham is correct, it’s appearing and disappearing at random. As a result, it could potentially strike any Federation or non-Federation world or starship without warning.
Assuming that this anomaly is the main problem facing Captain Burnham and her crew in Season 4, I’ve got a few ideas for what it could be, or what it may be related to. I quite like the idea of Discovery sticking with the “natural disaster” concept from Season 3. It worked well last time, and presenting the crew with a puzzle, mystery, or challenge that’s more scientific in nature than military could be wonderful to see. As long as such a storyline manages to avoid feeling either repetitive or anticlimactic, I think it works in principle.
One final point of note is that, due to disruption caused by the pandemic, Discovery Season 4 began filming back in November, well before Season 3 had finished airing – and crucially, before the creative team had time to process any feedback they were getting about the season’s themes and storylines. As a result of that, it may be the case that Season 4 doesn’t make as many changes from Season 3 as some fans would have wanted to see. But once again, that’s speculation on my part!
So let’s consider this “gravitational anomaly,” then. What could it be? What have we seen in past iterations of Star Trek that could potentially be involved? Will there be any tie-ins to other ongoing series, such as Picard, or will the show set up something we’ll see return in a future project, such as Strange New Worlds? Let’s jump into the list and see if we can make some reasonable guesses!
Number 1: The Nexus
When I first saw the teaser, my mind immediately went to the Nexus, the energy ribbon seen in Star Trek: Generations. The Nexus was large, more than large enough to engulf an entire planet, and while it may not have been light-years in diameter when we saw it in that film, it’s possible it grew… somehow! The Nexus was incredibly destructive, causing the destruction of two transport ships and seriously damaging the Enterprise-B, not unlike some of the damage suffered by the USS Discovery in the teaser.
There are two crucial points which made me think of the Nexus, though. The first is that the energy ribbon was said to contain a “gravimetric field,” which sounds an awful lot like Stamets’ “gravitational anomaly.” Both seem to be connected to gravity, and as we saw in the teaser, the USS Discovery appears to lose its artificial gravity at one point.
The second point I consider key to the Nexus being a possibility is that we already know it’s something that recurs. The Nexus returns to the Milky Way galaxy every 39.1 years (according to Data in Generations) and unless something major happened in the intervening centuries, this force of nature should still be present, periodically crossing through the galaxy.
At a couple of points in the teaser we saw members of Discovery’s crew looking dazed and confused, not unlike how Soran and Guinan appeared after being transported out of the Nexus by the crew of the Enterprise-B. Perhaps we can infer from their demeanours that they’re not quite sure where they are or what just happened – maybe that means they’ve just spent time inside the Nexus’ paradise-like realm.
Though the stated size of the anomaly relative to what we saw in Generations may count against it, I like the idea of revisiting the Nexus. Would Discovery bring aboard a Soran-like villain, someone hell-bent on getting to “paradise?” Maybe!
Number 2: The super-synths from Picard Season 1
It’s absolutely true that I also suggested the super-synths could’ve been the cause of last season’s disaster! But that doesn’t mean I’m done suggesting ways for this unnamed faction to reappear in Star Trek, especially considering that the teaser for Picard Season 2 suggested that series is moving away from them.
At the end of Picard Season 1, we learned that there is a race of super-synths that exist somewhere out in deep space – perhaps many thousands of light-years away from the Milky Way galaxy. They offered to come to the aid of any synths that ask for their help, though whether this offer was genuine or not was not clear – as indeed was very little about the faction!
Soji and Sutra, two of the synths from Coppelius, attempted to make contact with the super-synths, but despite opening a beacon and a portal to their base, Soji was ultimately convinced to shut it down and cut off her attempt to communicate. We thus learned precious little about who the super-synths are or what their objectives may be. They seemed menacing, and may harbour an anti-organic hatred that could make them diametrically opposed to the Federation.
We know that, in principle, this faction can open portals in space to allow for travel far faster than warp drive. Perhaps getting too close to one of their portals causes the kind of damage seen to the USS Discovery, and their portals may appear to be “gravitational anomalies” when detected on sensors. The super-synths clearly have a powerful understanding of gravity, such that they were literally able to move stars and create a stable eight-star octonary system. It’s thus at least possible that they use gravity or gravitational anomalies as some kind of weapon.
One thing that Picard Season 1 left unresolved was the fate of the super-synths. Having been contacted, were they now aware of the Milky Way and the Federation? Might they be hell-bent on attacking the Federation? If their offer of help wasn’t genuine, might they arrive to attack the synths who live in the Milky Way? There are a lot of unknowns, but it’s at least plausible that they could be involved. As I’ve said numerous times, finding a way for Picard and Discovery to work together, using similar themes, factions, or even characters would be fantastic and something truly worth doing. This may not be the way it happens… but it could be!
Number 3: A graviton ellipse
The Voyager Season 6 episode One Small Step introduced the graviton ellipse, a fast-moving anomaly that can travel through subspace, normal space, and even other dimensions. The ellipse was drawn to electromagnetic energy – such as that emitted by spacecraft! One ellipse appeared in the Sol system in 2032, during an early manned mission to Mars, and “swallowed” the Ares IV ship. It later attempted to do the same to the USS Voyager.
The graviton ellipse was smaller than five light-years across, so again we have to contend with size. But there are points in its favour! Firstly, the ellipse was specifically drawn to spacecraft and other future technology. Though we didn’t see it attempt to “eat” anything on a planet’s surface, it stands to reason that similar technologies used in power generation may emit the same kind of electromagnetic radiation that an ellipse would be drawn to.
Secondly, the ellipse moved essentially at random, disappearing into subspace to reappear many thousands of light-years away. One single ellipse was known to have visited both the Alpha and Delta Quadrants. This seems to fit with what we know of Discovery’s “gravitational anomaly” – specifically the part Captain Burnham told us about its random, unpredictable appearances.
Finally, the graviton ellipse was known to cause damage to spacecraft, draining their power, as well as gravity-related disturbances in space. An encounter with an ellipse may not have destroyed Ares IV or the Delta Flyer, but they were known to be very difficult to escape from.
The drawbacks of this option are that graviton ellipses were relatively well-understood as early as the 24th Century, and with Discovery Season 4 set over 800 years later, it stands to reason that the Federation would be well-equipped to at least know what they’re up against if an ellipse seemed to be in the vicinity. Secondly, there was no indication that the ellipse would stay in one area, causing widespread damage in the way Discovery’s fourth season teaser suggested. Despite those negative points, however, I think it’s at least a possibility. Perhaps post-Burn technology has drawn an ellipse to Federation space, or it’s even possible that someone has found a way to weaponise one to attack the Federation.
Number 4: The Sphere-Builders from Enterprise
Discovery’s third season had a couple of interesting references to Enterprise, specifically the “Temporal Cold War” arc. One faction involved in the Temporal Cold War were the so-called Sphere-Builders: extradimensional beings who were attempting to convert part of the Milky Way galaxy to match their native realm so they could colonise it.
Though the time-travelling agent Daniels told Captain Archer that the Sphere-Builders were definitively defeated in the 26th Century, Daniels was from a time period before Discovery Season 4 is set, so he may not have been aware of any future involvement they had in galactic affairs!
The Sphere-Builders, as their name implies, built spheres. These moon-sized objects were spread throughout a region of space known as the Delphic Expanse, and emitted huge amounts of gravimetric energy, causing the entire region to become unstable and peppered with anomalies.
The spheres were also able to cloak, concealing them from 22nd Century human and Vulcan ships. The region of space a single sphere could affect was huge, and in the mid-22nd Century there was a large network of them, perhaps consisting of over 75 individual spheres. A hidden anomaly-generating piece of technology with a connection to the Temporal Wars? That sounds like something that could cause the problems afflicting Captain Burnham’s ship as seen in the teaser!
If a rogue sphere were on the loose, if the Sphere-Builders were returning, or if a single sphere had been left in the Milky Way, forgotten about since the 22nd or 26th Centuries, it stands to reason based on what we know of them that it could be the cause of the “gravitational anomaly.” This concept is potentially interesting; a leftover “doomsday weapon” unattended for centuries could make for a fun story. It would also be great to see a tie-in with Enterprise!
Number 5: Tyken’s Rift
A Tyken’s Rift was mentioned in the Picard Season 1 episode Nepenthe, but before that one had been seen in more detail in The Next Generation fourth season episode Night Terrors. It was described as a rare spatial anomaly, one capable of encompassing entire star systems.
Unlike some of the other entries on this list, size isn’t a problem for a Tyken’s Rift! If a whole binary star system (i.e. a system with two stars) was able to fit inside, it’s more than possible such an anomaly could be five light-years in diameter!
The Enterprise-D wasn’t badly damaged by its encounter with the rift, but it was trapped inside and unable to escape. The Tyken’s Rift was also said to drain power, trapping ships inside. Perhaps the damage to the USS Discovery was not caused by the anomaly itself, but by pushing the ship past its limits trying to escape?
The drawback to a Tyken’s Rift being the cause of Discovery’s anomaly is twofold. Firstly, aside from a slow but steady power drain it didn’t seem to be harmful, and we saw nothing in Night Terrors to suggest this anomaly could or would cause catastrophic damage to a ship. And secondly, the Tyken’s Rift that the Enterprise-D encountered appeared to be stationary. It was even included on stellar maps, so it would be easily avoided.
I don’t think either of these points totally rule it out, and as one of the relatively few named anomalies in Star Trek that are massive enough, it seems fair to still include a Tyken’s Rift as a possibility.
Number 6: Species 8472 and Fluidic Space
One of Voyager’s most interesting adversaries was Species 8472, known only by their Borg designation! This powerful extradimensional faction were able to outwit even the Borg, fighting a very successful war against them for a time.
Species 8472 were native to a realm filled with an organic compound. Voyager’s crew named this region “fluidic space,” and it seemed as though Species 8472 based much of their technology on this organic material, including their spacecraft.
The Borg became aware of fluidic space some time in the mid-late 24th Century, and attempted to travel there and assimilate it. But Species 8472 proved resistant to assimilation, and waged a war on the Borg, eventually travelling through to normal space to continue the fight. The intervention of the USS Voyager gave the Borg an advantage, but it seemed shortly thereafter as though the war ground to a stalemate.
Species 8472 made one further incursion, but after an agreement with the USS Voyager, agreed to return to their own dimension, content that the Federation proved no threat. However, that was 800 years ago! A lot can change, and perhaps Species 8472 have decided to make a return.
This would change the “natural disaster” concept, making it perhaps a precursor to invasion. Whether that would be good or not depends on how well it was executed – as well as your personal preferences for storylines! Given what we know of Species 8472 and their technology, I think it’s at least possible they could be the cause. Perhaps Stamets’ anomaly is some kind of gateway to fluidic space.
Number 7: The Borg
On the other side of the war with Species 8472 were the Borg! I also suggested Star Trek’s iconic cybernetic villains as a possible cause of the Burn last season, and despite seeing some ex-Borg in Picard Season 1, we haven’t really seen the faction proper in Star Trek since Enterprise Season 2 in 2003. Perhaps now is the right time?
Borg technology outpaced the Federation in the 24th Century by a considerable margin, and I’ve seen nothing to suggest that wouldn’t continue to be the case. The anomaly Stamets and Burnham discussed in the teaser may well be a natural phenomenon, but if it turns out to be a weapon, I can think of few other factions capable of creating and wielding one so massively powerful. Other Borg technology, such as their transwarp network, was known to have gravitational effects as well, so perhaps that’s another sliver of evidence.
This doesn’t really fit with the Borg’s usual modus operandi, and that is certainly a mark against it! But then again, the Borg are very adaptable, and travelling back in time several centuries is not exactly standard procedure for assimilating a planet either, yet that’s what they tried to do in First Contact! The gravitational anomaly could be the opening salvo of an attack; the artillery barrage to soften up the Federation before the Borg drones rush in to assimilate the survivors. The Borg certainly seem capable of doing something like this, and with the Federation having been on the back foot for more than a century as a result of the Burn, the Borg may have been using that time to build up and prepare for a large-scale invasion attempt.
We don’t know for sure if the Borg are still around in the 32nd Century, or if they still hope to one day conquer and assimilate the Federation. After more than 800 years, anything could have happened to them! However, it’s plausible that they still exist in similar form to how we last saw them.
The anomaly seemingly “attacking” both Federation and non-Federation targets could be indicative of an intelligence at work behind it. Space is huge after all, and the chances of it hitting a target as small as a starship, starbase, or planet regularly seems unlikely without some kind of explanation. Is it a force of nature drawn to energy, like the graviton ellipse mentioned above? Or is it a Borg weapon deliberately targeting Starfleet? The latter may seem unlikely, but it’s not impossible!
Number 8: The Burn
I certainly hope that Discovery Season 4 doesn’t just drop the Burn and proceed as though it never happened. After the cataclysm caused huge disruption to the Federation and the wider galaxy for over a century, I think we need to see a lot more of the consequences of that event before we even consider a “reset” of the Federation!
Perhaps what this anomaly will be is some kind of “mini-Burn,” affecting a smaller area. It could be a ripple effect of the original event, or otherwise connected to it in some way. Hopefully it won’t be caused by poor Su’Kal, who’s been through enough over the last 125 years! Though the Burn was presented as a unique event, perhaps it had lingering effects that are only just becoming known.
Season 4 needs to walk a line between acknowledging the events of Season 3 without dwelling on them the whole time. I understand that the writers and producers have other stories to tell in the 32nd Century beyond the Burn, but given how catastrophic it was I feel strongly that we need to see at least some of its lingering impact. Connecting the Burn to this new problem would create a degree of separation, allowing the season to go in new directions but without dropping the massive event entirely.
The Burn was a disaster which “caused dilithium to become inert,” and which caused active warp cores to explode. It wasn’t known to have gravitational effects, instead being some kind of shockwave that travelled through subspace. That could certainly count against it!
However, if this event were connected to the Burn in some other way, rather than being a direct result of Su’Kal’s outburst, perhaps it could be explained. I couldn’t even guess how such a connection could be made; it would be some kind of technobabble connecting the anomaly to dilithium and/or subspace. But it could be done, and it could be made to fit!
So that’s it. Eight very early theories about Discovery Season 4 and the mysterious “gravitational anomaly!”
As mentioned at the beginning, I quite like the idea of the series going down a “natural disaster” route, allowing the crew to solve a puzzle and unravel a mystery, rather than simply pitting them against a Federation-threatening adversary. Perhaps that will be what ultimately happens, but I think it’s at least possible we’re seeing some kind of attack or weapon as well. Time will tell!
The teaser was action-packed, and the new season looks to be in great shape. I think that there are possible downsides to another “huge galactic disaster” storyline so soon after resolving the Burn, in that it risks feeling tacked-on, derivative, or even anticlimactic if it’s an event smaller in scale. But despite that, if this anomaly is going to be one of the main storylines in Season 4, there’s a huge amount of potential.
Star Trek’s past didn’t provide the key to understanding the Burn last season. Will something we’ve seen before come into play in Season 4? Maybe!
Star Trek: Discovery Season 4 will debut on Paramount+ in the United States, and on Netflix in the United Kingdom and elsewhere, sometime later this year.
