The Matrix franchise has a pretty simple premise as far as sci-fi goes, but the closer you look, the more complicated it gets. The first movie stands on its own very well, as many sci-fi blockbusters do, but extending the story and expanding its world created a lot of new questions – and not all of them can be answered organically in the format of an action movie. With three original movies and a belated fourth installment now out there, The Matrix has raised a lot of questions without answering them, even if major themes are reconciled in the end.

Most Matrix mysteries revolve around small world-building quirks, not gaping plot holes. For a film series with a tight runtime, The Matrix actually fleshes out its world pretty thoroughly relative to some other sci-fi behemoths, and where it doesn’t, there are plausible answers that simply haven’t been confirmed (yet). Personally, I don’t think we should expect the most robust sci-fi concepts to be fleshed out in a film — we should reserve that for long-form media like series, comics, and prose. This is definitely the case for The Matrix, where many questions are answered by implication instead of being outright spelled out.
Still, The Matrix franchise is moving forward with a new film in development at Warner Bros. and potential spinoffs on the table as well. These are the kinds of productions we should expect to answer the nagging questions of the four movies we’ve seen so far. Here are three of the biggest Matrix mysteries that could serve as springboards for future installments.
How Are New Children Born?

Over the years, fans and critics have often pondered how new human children are born inside The Matrix itself, when most of humanity lives within a simulation, and their real bodies never leave their tanks. We’re told that in the real world, their bodies are engineered and grown within the tanks using The Machines’ advanced technology — as opposed to characters like Dozer, who were born naturally in Zion. However, it’s never explained how exactly the Matrix simulates the birth of a new person while engineering them on the outside as well.
The most popular fan theory here is that programs within The Matrix monitor when two humans are planning to procreate, and harvests their DNA to synthesize their child while the humans go through a simulation of pregnancy. The more you think about this, the more incredibly precise the timing would have to be, though it is certainly within the scope of the Machines’ powers as we know them.
Another popular theory is that the tanks not only sap energy from the humans, but help to give them supernaturally long lifespans. The humans could then cycle through multiple lifetimes in the Matrix, living as different people each time. This would match with the series’ overall transgender allegory, as it would add a twist of body dysphoria, but that could also mess with the humans’ immersion in the simulation. Agent Smith did say that the Matrix has to be as realistic as possible or else the prisoners’ minds might reject it, after all.
Trinity’s backstory offers us a twist on that last theory — she claims that she once had two children in the Matrix, but she eventually learned that they were only programs put in place to mollify her and keep her docile. Some fans speculate that all children within the Matrix are in programs like this, while the adult prisoners do not notice that neither they nor their offspring are aging. Again, this would require that humans are incredibly long-lived and that their memories are altered quite often.

Does Sati Have Control Over The Matrix?

By the end of The Matrix Revolutions, the exiled program Sati seems to be nearly as important a figure as Neo. She was created without purpose through the love of two other programs, Rama-Kandra and Kamala. Her parents arranged to have her smuggled into the Matrix to live among humans so that she would be less likely to be found by the Machines, who would likely delete her since she had no function. At the end of that movie, Sati, the Oracle, and Seraph watched a unique multi-colored sunrise together, and Sati said she had created this sight for Neo.
All this implies that Sati is a unique new evolution, combining the strengths of humans and Machines into an entirely new form of consciousness. However, in The Matrix Resurrections, Sati displays no such powers or purpose. Grown up now, she reveals that she knew Neo and Trinity had been resurrected and held prisoner for 60 years, and that her father was actually the engineer in charge of their new tanks. However, there was no hint that she could manipulate the simulation as we saw her do before.
Sati’s story in Revolutions was so promising, and it was disappointing to see her fade into the background of Resurrections. With more Matrix stories coming, hopefully, one of them will shed light on Sati’s life as a free entity and how she’s using her unique gifts. As it stands, we have to wonder why she wasn’t arranging vivid sunrises or working other miracles in the latest timeline.
Is Trinity “The One?”

Finally, The Matrix Resurrections throws a wrench into the concept of “The One” by granting Trinity many of the same powers that Neo has, which are supposedly unique to this singular, pre-destined hero. As mentioned above, The Matrix franchise is usually pretty good about explaining anomalies like this, so it’s a little odd that the movie left this one up for interpretation.
We know that The One appears in cycles to “reload” the Matrix and that the five Ones before Neo all chose to maintain the status quo rather than risk human extinction. Neo broke that cycle through the power of his love for Trinity, and as a result, they both died at the end of The Matrix Revolutions. Resurrections doesn’t dispute this — it tells us that Neo and Trinity were in fact dead, but they were resurrected by the Machines so they could be studied, and ultimately, tapped for the immense power of their bond.
With Neo’s death, it’s possible that the cycle moved on to begin searching for the next One, and it’s possible that a resurrected Trinity looked like the perfect vessel for that power. At the same time, there are plenty of other explanations that make sense as well. It’s possible that all the manipulations of The Analyst and this foray into unknown territory triggered something within the Matrix, so that multiple people can now tap into the powers of The One, or that Neo and Trinity were so entangled that they were able to share these powers. Whatever the case, it’s definitely not cut and dry by the end of the movie.
Hopefully, The Matrix franchise plans to continue answering its biggest questions without contradicting itself in the process. The series is facing its biggest change yet, as the next movie will be the first not to be directed by either of the Wachowskis. In the meantime, the original Matrix Trilogy is streaming now on PlutoTV, while The Matrix Resurrections is available on Max.
