Unanswered Questions

Even though the main explanation is consistent and ties the whole movie together there are still a few parts of the movie that are not explained and have to rely on theory. Here are some of those questions with possible explanations and some common mistakes people make.

What Creates The Tangent Universe

Time PortalWhy exactly does a Tangent Universe (TU) occur? Are they a natural phenomenon or are they artificially created. There is one theory that scientists in the future build a machine that somehow causes a rip in time back in the past. Another theory is it could have been caused by Alien involvement.

Quite a common thought is Frank saving Donnie in the beginning is the cause of the TU. Donnie was meant to die and by surviving he altered things which caused the corruption. This is not true though, we are already within the TU when Frank wakes Donnie up. Frank's special powers only work within the TU so he would only be able to wake Donnie after the TU had started.

The same goes for the Artifact not being the cause of the corruption. The jet engine appears several minutes after the TU had started. The Philosophy of Time Travel states that the Artifact is the first sign of evidence that a TU has occurred.

The First Jet Engine

The ArtifactOne major question is where does the jet engine in the beginning of the movie come from originally? If it came from the future where exactly and what day did it come from?

A common answer to this question is it's the same engine Donnie sends through the portal from the plane his mother and sister were on. The engine travels through time and lands on Donnie's house. It's exactly the same event as the end of the film only the first time round Donnie survives.

This is extremely unlikely though as the portals are just a gateway between the two Universes. The first engine lands in the Tangent Universe (TU) so if it came through a portal it would have to come from the Primary Universe (PU). The engine Donnie rips of the plane at the end is from the TU and travels through a portal into the PU so there is no way it can be the same event repeating.

If it did come from a future point in the PU once the corruption is fixed by Donnie that future event won't happen now so we will never find out exactly how it occurred.

Another theory is the Tangent Universe is a copy of the Primary Universe but as it's being formed there is a glitch or copying error. This error produces a duplicate engine that is then dumped into Donnie's bedroom. This anomaly makes the TU even more unstable and it must be sent into the PU.

Roberta Sparrow: The Philosophy Of Time Travel

Roberta Sparrow (Grandma Death)Roberta Sparrow writes the book "The Philosophy Of Time Travel" which helps guide Donnie but how exactly did she know all this information? There are a few plausible explanations for this. It seems like she had a similar experience herself so either she was a Living Receiver or one of the Manipulated Dead in a previous Tangent Universe.

Both options would in theory give her all the information required. If she was a Living Receiver she would obviously have known what to do and the Manipulated Dead have a large understanding of what is happening within a Tangent Universe. It's possible she may have somehow retained some of the information from her experience once the Primary Universe started up again.

Does Donnie Have To Die

Donnie DarkoThis subject is one of the most debated parts of the movie. A lot of people make the mistake of thinking Donnie waking up and cheating death in the beginning is what caused the Tangent Universe (TU) to occur. The assumption is then once the Primary Universe is restored Donnie stays in bed otherwise he risks causing another TU to start and the whole cycle will repeat. This theory is not correct though, Donnie and Frank have nothing to do with the creation of the TU.

We hear about other Living Receivers in The Philosophy of Time Travel who were killed by the Artifact they returned. If we include Donnie then it seems the Living Receiver always dies once the Primary Universe is restored. The question is what would happen if Donnie got out of bed again and survived? The moment we see Donnie laughing in bed at the end the Primary Universe is already restored. If Donnie got out of bed and dodged the second engine after that then in theory nothing would change as the corruption is already fixed.

Another important point is whether Donnie chooses to die. The Donnie we see in bed at the end is not the same Donnie from the last 28 days. How much knowledge he has of what happened in the TU is very questionable and it’s quite unlikely he knows he is about to die.

The question of destiny plays quite a big part here, Donnie was meant to die but Frank saved him. It’s possible he was chosen as the Living Receiver because his life is now expendable; he is going to die anyway. Once back in the real world it's Donnie's destiny to die.

I believe Donnie stays in his bed, knowing he would die at the end of the film. He realized during his time in the TU that following his fate (the water-like spear coming from his chest as seen when Donnie finds his dad's gun or at the Halloween party) lead him to saving the entire universe including his family and one true love, Gretchen. He fully realizes that if it had not been for Frank waking him up, he would have died from the jet engine, thus that was originally his fate. Donnie is very happy to know he is continuing to follow the "righteous path" (God, fate, whatever you decide) and die like he was originally planned to.

Side note: he could also see his own death as a sort of atonement for murdering Frank (even though he had to from a plot perspective).

I think Donnie chose to die thinking that if he lives, the tragedies occurred in the Tangent Universe would happen in the Primary universe, which is actually not the case, because as what have been mentioned previously, the glitch has already been fixed when he woke up. In other words, Donnie made an "unnecessary sacrifice."

So technically, Donnie knew all along about the powers he had and what his ultimate mission was? And if he did, why didn't he do it earlier, why do it only when Gretchen was dead?

So do you guys think its possible to find a worm hole?

"Frank had to die in a previous tangent before coming back to rescue (and guide) Donnie. Since the tangent universe is eventually destroyed by being reset, this is how Frank initially died and then returned in the next tangent universe as the Manipulated Dead and guided Donnie to eventually shoot him (part of the Ensurance Trap set for Donnie to send the engine back). "

I disagree the destruction of the world is how Frank initially died. as the destruction of the world would mean the destruction of also the PU and everything in existence. In the first original TU Donnie died, as Frank wasn't dead yet to go back and save him. The Halloween party still happened and Frank still went on the beer run which I believe was to go to cellardoor to get the beer. However, Donnie wouldn't of been there and so Frank would of go into the cellardoor where the bullies were with the knives and they would have killed Frank. This would allow him to become a manipulated undead and travel back in time to save Donnie from the flight engine, as he was the receiver and needed to be rescued to save the world. It also has merit as the bullies have knives which would have been used to kill Frank. and Donnie also used a knife in the mirror to attack Frank, perhaps foreshadowing what happened in future. This theory there is only one TU but is looped backed to the beginning once from time travelling Frank after his death with the bullies in the cellar.

Another theory to add onto this but is wild and I cant find much evidence is that Frank is the son of Mother Dead and that is why he went to the Cellardoor for beer and also why he seems to have previous knowledge of POTT

The one thing that really bothers me is that the element of metal is a required element. I could understand that water would be a worthy element because I could understand that a TU would not be created until the stabilization of the PU. To JUST USE Earth as our example: Until the stabilization of the planet, the PU would be a Chaotic and NATURALLY Disorderly existence - therefor, disorder is order and so a TU cannot occur. OK, so when the planet forms, water is formed as well and order becomes the norm. It is when the beings of Earth CREATE Disorder, that a TU may occur, because the PU is being given Disorder when it is in a state of Order. So, to me, that is the pre-requisite of the PU being "ripe" for a TU.

So, my issue with Metal being a required element for the artifact is this: What if a TU occurs when there is no civilization that has discovered Metalurgy? the Clovis People, for example, used Stone Tools. Even though the Clovis People could have brought Disorder to the PU (which they did, they had plague, famine, war, death,...blah de blah) how could the Clovis, or any other group of Ancient Peoples NOT HAVE CREATED a TU? On that note: Why didn't the KT Event cause a TU? Or any other Mass Extinction for that matter? Am I to believe that this schism in Space-Time is carrying a watch? It just simply ISN'T disorderly enough in the PU until society creates metallic items? It isn't disorderly enough until Humans?

If I am to accept that an outside source created the tear in Space-Time such as Aliens, Scientists, or whatever: it's awfully coincidental that these rifts ONLY occur when Metal is a known product. If one SINGLE event occurred at any time on Earth during anything besides the past 3000 or so years, the PU would be in a perpetual catatonic state while a never-ending loop of TUs occur. That's...stupid. Why is Metal a required element of the artifact? It either is, and somehow the Movie's Universe is fantastically lucky for the sake of a complicated and intelligent plot that is remarkably short-sighted, or it isn't a requirement and Grandma Death was wrong...which makes her exceptionally lucky to have written a book about the experience as a whole that coincidentally fits PERFECTLY with the experience shown in the movie.

Seriously, it's highly suspect that a Rift occurs ONLY when Metals are understood enough to have an artifact at all, and ONLY when there is a society that could produce a Living Receiver. During the Billions of years of Earth's stable existence...No issue happened, convenient. So perhaps someone made a rift in existence (maybe twice...if Grandma was a survivor, or even more if she actually cites real events in those myths.) and it just so happens to occur in a time period that has refined metals...every time. If someone knew about the rifts and purposefully kept rifts during these time periods: A: why would they make them, risking the fabric of existence itself, and B: how could they police the use of rift-making ghosty-stuff to ensure it's done only during times with Metal?

Honestly, the more I think of this, the more I dislike the movie. I thought the movie was a pretty fun experience, but I hate when time travel gets put into media because people are terrible scientists. Donnie Darko is a cool movie, but I strongly believe it's intelligent for narcissistic reasons and ultimately actually idiotic.

I'm An Avid Fan.

I've either forgotten, or never realised, how does the TU work?
I think the PU paused completely until the safe unraveling of the TU has taken place then the PU resumes as normal.

At the begging img of the TU cycle, how does Donnie survive the crash allowing him to reach his future and kill frank, so frank can travel back in time and save him. If Donnie died initially frank couldn't have gone back and woke him up because Donnie didn't survive the crash to go and continue his journey and kill frank!?!

I think Donnie chose to die because he's suicidal. After waking, having some knowledge of the last month, Donnie concludes that despite a completely Donnie-centric world, he still loses and is ultimately troubled. Its like a big joke; Donnie laughs at how pathetic and worthless he is and as a final "screw it", he faces his depressed state with a malaise confidence and lets fate take him. Its like the person that shoots themselves: the person crying wont pull the trigger, it's the person smirking that will - suicide is a "final option" that is darkly relieving.

Yes. A sequel would be awesome. It would be sooooo chilling to hear donnies voice telling gretchen to "wake up".
