Time Travel and Superposition in Dark

I was no more than four years old when our car got stuck on a snowy hill decades ago. Everyone but me went outside to push to get us out of the frozen road. More people gathered from other cars to help each other, and soon everyone was engaged in a small rescue operation. That certainly didn't mean I didn't help—as well as others pushing the car from the outside, I did the same from the inside. From the back seat, I put my hands on the front and pushed hard. In my defense, deep down I knew that what I was doing was kind of weird and useless. At the time, I just didn't know why. I was just ashamed sitting alone and doing nothing. Well, like they say, with age comes wisdom, and now I know that what I did was physically impossible, just like in the case of Baron Münchhausen—when he got himself and his horse he was sitting on out of a swamp by pulling his own hair upwards. And just like in an old expression about an absurd and impossible thing one can do—if I were to pull the bootstraps on my shoes up, lift myself into the air, and jump over the fence.

In science fiction, the word bootstrap is also used to portray the impossible task in all the paradoxes that are always hard to understand. Within time travel, the bootstrap paradox is a theoretical paradox that occurs when an object, information, or human is sent back in time and becomes trapped in the infinite cause-effect loop in which it no longer has a detectable point of origin. For a simple example, if I somehow send a copy of this very blog post to my younger self before I write it in the first place, the origin of the text becomes utterly unknown. It exists in the time loop, and I become just somebody who typed it in. Yet, the text will still have my own style of writing and my own thoughts written down and not somebody else's. Hopefully, you will not find this case implicitly weird, because weird in this blog post is yet to come.


I have been aware of the existence of Netflix's 'Dark' for a long time now, but due to its scientific background and complexity, I knew it required continuous binge time to watch it, and last weekend I finally decided the time was just right, and I swallowed all three seasons in just three days. Like no other TV show, it was solely based on time travel and quantum superposition, and... in a word, it was outstanding. With lots of characters to follow through both space and time, it did require full concentration, but thankfully, due to the fantastic direction, script, and performances of all involved, it was more than understandable and enjoyable, to say the least. It is impossible to continue this without spoilers, so if you are eager to watch it first, this is the point of this blog post to stop reading, and I advise it strongly.

Anyhow, Dark's premise is all about bootstrap paradoxes. There are multiple plotlines in the show heavily embedded in time loops, just like my example of this blog post traveling to the past. If that was weird, imagine what this kind of paradox, involving time travel of real people and their intertwined stories, could do to your sanity only as an observer. On top of that, season one passed with very few or no special effects, and there was no reason for that either. In Dark, all the post-time-travel effects are already embedded in the future, or the present, from where they traveled back in time. For example, Helge already had all visible face scars that were consequences of Ulrich's time travel. Also, the stories about the murdered woman on the bottom of the lake were already socially spread even before Katharina was murdered in her own time travel.


Even though Mikkel's time travel was the prime story behind Dark, where he ended up being a father to Jonas, the main protagonist, for me the strangest and most ingenious bootstrap paradox is Charlotte, who was born in the future, traveled to the past as a baby, and became a mother to Elisabeth, who in her own future became a mother to Charlotte herself. The endless loop between them lies in the fact that they are both mother and daughter to each other. And even this is not the weirdest bootstrap compared to the entire Nielsen family. Martha and Jonas' child, who is in the show and the strangest character of them all, in his own time travel became a father to Tronte, who was Martha's own grandfather. This practically means that Martha's son was his own great-great-grandfather. In the aftermath, most of the members of the Nielsen family are practically the result of a direct or inherited bootstrap paradox and have to thank their existence to time travel itself.

To be honest, I was so perturbed and unsettled with all the relationships by the end of season two that I was not sure how they would come out of this at all. There were so many open loops with no indications how it could go any further. At that point, I thought that this show would go down the drain very quickly, or they must come up with something even more out of the ordinary to continue the story. And then, at the very end, in the last episode, came another Martha, who stood by the dead Martha and answered Jonas' question about where she came from exactly with "Die Frage ist nicht aus welcher Zeit, sondern aus welcher Welt". Well, I am not fluent in German at all, but I know a word or two, and in this case I knew very much the difference between Zeit and Welt. In the outcome, even before the subtitle showed up, I was left staring at the screen with my mouth wide open.


The final season introduced even more time travelers, both new and doppelgangers, but more importantly, the story started to unveil now with the introduction of the cause and effect of the quantum superposition mirrored in the macro world(s) and character's actions. In the quantum world, superposition means particles can exist in different states and even multiple places at the same time. The weirdness comes if we try to observe the process. At that instant, superposition breaks into just one outcome of their many. Just like with the double-slit experiment of light behavior* or in binary superposition with Schrödinger's cat in the show explained by H.G. Tannhaus in one of the episodes.

The difference between the micro and macro worlds, with time travel involved, was that in the macro realm it was now 'possible' to act differently in the same time loop and in one pass to choose one outcome and in the other a different one. That allowed for the same superposition collapse, but in two time loops to create two different Jonas' and two different Marthas and to even further complicate the intertwining situations now with three worlds involved. In the ingeniously written ending of the show, as I expected, time travel loops were impossible to untangle, and the only outcome was, again with time travel interfering, to save one world at the expense of the other two and, by doing so, to prohibit any time travel in the original world.

The ending of two worlds disappearing was just perfect and beautiful, and the very last scene explains which of all the characters survive existence and which ones were only products of either direct or inherited bootstraps and therefore not possible to exist in the final world.

Technothrillers

You know that feeling with reading novels when your bookmark location is in the second half of the book and you find yourself turning pages faster and faster in order to find what happens next? If your reading interests coincide with mine, the most likely case is that you are reading either science fiction, spy or fast-paced action thrillers, or good and old adventure stories filled with espionage and politics in the background.


Well, that was before. Nowadays, if I wanted all that combined in a single novel, there's a new subgenre called technothrillers, and with some of them, especially with new authors in the self-publishing realm, and on almost all occasions, I found myself turning pages even faster. Three of those great technothrillers you could find are presented in this blog post. The premises are extraordinary, and all of them are borrowed from science fiction: smart robotic nanoparticles enhancing human bodies, evil artificial intelligence operating on Darknet, and one extraordinary idea of teleportation based on time travel.

Let's start with a nanoscaled interface between the human brain and computers. It has always been a holy grail to make this efficient ever since the invention of the first computer. Even now to create this post, I am using the old-fashioned keyboard to type the letters, checking for typos, taking care of the grammar, and rolling the mouse around the table for lots of other commanding purposes. "Interface" by Tony Batton is giving us all the potential outcomes of the system without all those helping gadgets only by using nanoparticles with remote access to everything with a CPU and with the thriller plot that is, in one word, outstanding. I will only add that I touched the icon for the sequel purchase just a couple of moments after I finished the book.


For the next technothriller in line, these three reasons were enough for me to hit the download button: DarkWeb & Net layers of the internet, villain AI, and automated corporations. It was amazing how all this, not so hard to imagine, near future inspired Matthew Mather to create this astonishing novel named "Darknet". Simply put, I felt that all that's happening in this techno adventure was as real as in any ordinary thriller. This reality, in one way or another, is really knocking on our doors, especially the part with automated corporations with no need for humans in roles of CEOs, CMOs, CTOs, and all the other C?Os. The scary part is that we don't even need supreme AI to take over, just advanced automation. The thriller part of the book is as perfect as the premise itself. Enough said.

Last, but not least, comes the boldest sci-fi premise in Douglas E. Richards' "Split Second". While at first it is not immediately comprehensible how time travel can be used for teleportation and then for the entire thriller story, it is quite simple really. I don't really like to spoil the book here, especially since the author kept the details from the reader for a big portion of the pages, but I have to say that it is an ingenious idea. I will just give you a hint to think about it: we are living in a universe with four dimensions by its nature, three spatial ones and time as the fourth. If we move along one dimension, i.e., up and down, we are not really moving left or right or forward or backward. We would be only using one spatial dimension and traveling forward in time. The other two spatial coordinates would stay the same. Similarly, the question from the book was, what if we were able to use only the time dimension and move just a fraction of a second forward or backward in time and NOT use spatial dimensions by doing so? Where exactly would our spatial coordinates be AFTER the time travel? Where would everything else be after our arrival? If you are intrigued, this book is definitely for you.


To summarize this spoiler-less review, even though I liked and enjoyed all the stories the same, the plausibility of the background science fiction is always important to me, and with these three, "Darknet" is maybe something we could witness within our lifespans, and just for that fact, if I had to rate these three technothrillers, it would be my first choice of recommendation. As much as I would love to see something similar to the nano-sized robots floating in our bloodstreams, the "Interface" premise is still going to wait for a better understanding of our own intelligence and brain activity. The wait must also include significant nano-scaling of the CPUs as well. As for the time travel, if you ask me, this might stay in the fiction only for a very long time, perhaps even to stay in the realm of the impossible, but who knows, we might witness one-day time travel of the information data somehow if sending any mass back in time proves to be unfeasible.

Nevertheless, I truly enjoyed all the twists in stories, all the characters and their interactions and development, writing styles, and how everything unfolded at the end of all three novels. A warm recommendation goes without saying.

Schrödinger's Cat and Intelligent Movies

In short it goes like this: "There's a cat in a box... That has, like, a 50/50 chance of living because there's a vial of poison that's also in the box. Regular physics would say that it's one or the other. That the cat is either alive or dead, but quantum physics says that both realities exist simultaneously. It's only when you open the box that they collapse into one single event." This quote is me paraphrasing James Ward Byrkit, writer and director of the movie "Coherence", which I've just watched. Although Erwin Schrödinger, back in 1935, when he first wrote his famous thought experiment, invented a pretty complex radioactive trap for the poor cat inside the box, I think that "vial of poison" and James' full description in the script is one of the best interpretations of the quantum paradox there is. The quantum weirdness is one of the most intriguing areas in science that has been buzzing our minds for about a century now. I wrote about it a little last year in the post Quantum Weirdness, and when it comes to science, it was one of the posts I enjoyed writing the most in the past.


About 90 years ago, Niels Bohr, the greatest Danish physicist of all time, described quantum mechanics with perhaps the best explanation ever since. He said something like this: "A quantum particle doesn't exist in one state or another but in all of its possible states at once. It's only when we observe its state that a quantum particle is essentially forced to choose one probability, and that's the state that we observe. Since it may be forced into a different observable state each time, this explains why a quantum particle behaves erratically."* Well, describing the quantum behavior has been a challenge ever since, and because of Bohr, who managed to do it first, all other explanations combined we call today "The Copenhagen Interpretation". Schrödinger's cat is just Erwin's metaphorical attempt to put it closely into our world of big, which we should understand better. But we will get back to the 'cat' later.

And relax, this is not going to be a scientific post or some nerdy brainstorming and (usually) utopistic ideas of mine. Instead it will be about movies. Yep. Just a short glimpse of one of my favorite directions within the sci-fi genre of movies. The one where, just like with reading books, you don't need any big productions, fancy and state-of-the-art visual effects, expensive sets and VFX, or famous actors to create great entertainment. This is a genre I like to call sci-fi for the brains. Like in the movie "Coherence", the plot is placed down to the real people, or to be precise, into familiar settings. There are no spaceships or vividly animated aliens or any villains for that matter. All you need is your imagination and a little background knowledge, and that's all.


I will show you now three movies. I recommend them warmly and without spoiling the films too much for all of you who still didn't have the chance to watch them. A couple of days before "Coherence", I saw the blockbuster "Edge of Tomorrow". I liked it a lot, of course, but still, even with a great cast and effects, the story is nothing exclusive or new. It also provides expected closure and leaves no room for too much thinking or brainstorming over the story. On the other side, "Coherence", with its relatively anonymous cast and script that can easily fit within the set in some small theater or school gym, tried to exploit the very cat of Mr. Schrödinger's and provide one more Copenhagen interpretation, only this time with people in main roles and our own personalities instead of "a vial of poison". It all started with a simple dinner party and with ordinary people who eventually realized what might happen when you open the box. Is the cat alive or dead, or, to be precise, what is really happening when different possibilities emerge out of the box at the same time? Try to find out at the end of the movie. It's not what you might expect and what we got used to in regular movies, but not every story has a happy ending. I guess in this one, the ending is like in quantum mechanics and like the cat from the century before, "Coherence" has both a happy ending and ... not. You have to see it to understand. That's all I will say.

The second sci-fi jewel in the same subgenre is "The Man from Earth", written by Jerome Bixby and directed by Richard Schenkman back in 2007. The science behind this one is biology and how, in its most divergent (and also on the edge of impossible) path, it might affect the very history of mankind. Or to be precise, explained it. The story focuses on John Oldman, the man who, due to some biological anomaly, hasn't aged ever since he was born in Cro-Magnon tribal society 14000 years ago. Like any other science fiction, the movie doesn't try too much to explain the reasons for his presence and instead portrays his struggle to fit, ability to learn throughout time and adapt to different parts of the world, and his everlasting craving to tell somebody his story. And this film is exactly what it is about—finally, the "old man", Oldman, currently a university professor who's about to leave and start another loop, decides to share everything with a group of his peer colleagues. Well, he will learn that impossible stories like his one are not possible to be accepted that easily or at all. But the audience behind the screen will get great entertainment and possible solutions for some parts of our own history, and especially religiosity and its main figures during the eons. Including Buddha and Christ. Oh yes, and don't expect the sword fights, mad scientists, or any action at all, like it was in "Highlander" and its almost stupid plot with cutting heads off for the "prize". The set of this movie is only one small living room. The only thing you have to do is sharpen your brain cells before clicking the "Play" button.


Finally, the last one is "Primer", an extraordinary film written, directed, and produced by Shane Carruth. Shane was also playing the main character in the movie, and the entire project finished with only $7,000. It's hard to say what science is behind this one. Probably the best bet is to use the word "fringe" for this, as the main theme and background technology is "time travel". The script is based on one of the oldest time travel paradigms. The one that doesn't include parallel universes, and instead the time traveler is ending up in his very own universe where the danger of the "butterfly effect" can ripple the time stream and change everything. This is the most intelligent script and movie I have seen so far, and before I watched, I read some reviews and remember this one: "Anybody who claims they fully understand what’s going on in ‘Primer’ after seeing it just once is either a savant or a liar". Well, I am not either, and to be completely honest, I didn't manage to follow the entire story and understand it after the first (and last) watching, but more or less I got almost the whole picture from that only session.

The key point in understanding the science (fiction) behind "Primer" is to comprehend what is happening with the guy who enters the time machine and, when he does in the first place, why his major concern is to make sure that his parallel copy enters the box no matter what. The problem with this is well speculated in the article from Discover Magazine I read once, and in short, if time travel into the past is possible, nature must have some mechanism in order to prevent inconsistent events like in this case, the non-entering of the box by the time traveler after the loop is initiated. Confused? Maybe to better understand this paradox, take a look at this image***:


The hazard is obvious: if the "original" in its own blue timeline didn't enter the box at 6PM, the green parallel timeline would not exist in the first place. In other words, if "double" meets "original" and stops him from entering the box, the paradox is obvious, and we can only imagine what happens if that "butterfly" occurs. That's why "the science fiction behind time travel" in recent years actively rejects this approach and involves another universe being the destination for time travelers instead of the origin universe, which would explain the consistency of traveling into the past. Of course, we might ask what would happen if ALL "originals" from ALL universes decided to time travel? Whatever universe they arrive in, the copy of them will be needed to enter the box in the destination universe, and we have the same problem again; let's call it the "Multiverse Butterfly Effect"... Anyway, if you didn't see "Primer" or want to watch it again, try to comprehend this image first. It will help a lot.

These three movies, even though from the same genre and subgenre, differ in the background science used, and I can't truly compare them with each other. So I can't favorite one of them, but these are the movies I like to give thoughts to again and again... They are not really made for just entertainment and, for me, are more memorable than regular sci-fis.

Welcome to MPJ

Hello folks, or should I say random web reader! Or perhaps you are here on purpose. Or maybe you are a humanized or automatized bot or crawler, doing your scheduled intelligence for whatever reason you do that every now and again. Either way, now that you are here, this probably means you read at least one of my posts and are now wondering who I am? Well, even though I believe in privacy on the net, I guess when you are having a public journal, it is not really possible to maintain. Therefore, I created this page so I can introduce myself a little and say something about the blog itself.

My name is Milan Zivic, and basically, this would be just a stream of my texts, thoughts, or whatever I think is worthwhile publishing. Actually, I don't think of myself as a writer, especially in written English, which is not my native language, and the fact is that this is not what I do best. What I do best is programming, and I have been doing that for several decades professionally. I like to think that I am one of those at the other end of the outsourcing chain. However, writing is sort of a habit I am enjoying more and more with every passing year. The feeling is just right, and as long as I have ideas, inspiration and imagination, I will be around.


On the other end, I really wish to have more time for writing, but free time is something precious these days, and ultimately, in short, I decided to establish a website instead of actively participating on several social networks. I think it is important; after all, every now and then, I have something to say. It's not always smart or right to the money, but this way it will stay written rather than forgotten, and someday far in the future it will be a nice collection of thoughts and written memories.

The website structure itself is more or less the same as what you can stumble on in all other weblogs on the web. Additionally, my own background within web design and website development is giving me a chance to maintain a little bit of a customized look and feel for the complete application. I chose Blogger to host it mainly because it is one of the best services out there, and they did a really great job connecting blogs with other services, not to mention that using client scripting is free and almost without any limitation. Please do not hesitate to share stories you like on your favorite network for discussion, feedback, complaints, etc. Please feel free to contact me on any occasion and for any feedback.
