There is a theory within the field of science fiction known as the [Multiple Present Theory]. It's one of the classic paradoxical theories of time travel that essentially, I've started to think more deeply about it.
The lines have long since disappeared. Sophia went home after dinner. Now I'm on the roof of the apartment complex, smoking a cigarette.
As she was saying.
The [Multiple Present Theory] shows that if a reality is altered, a kind of different timeline would be created but without erasing the previous one, so that both the memories of one reality and the other are real. It is said that the individuals coming from them are aware of it to the point of confusion, because they do not know how to differentiate in which reality they live.
That's according to Wikipedia.
In particular, that is the only explanation I have regarding what happened with the lines.
I'm not a big fan of science fiction, in fact, I don't even know much about that genre. They are just mindless speculation on my part and nothing more than that. I don't really know if that was reality or if I was hallucinating like the most idiotic.
Only...
I have this feeling of something out of place. It's just a hunch, but since I don't know what what I saw is about, I can't give a totally concrete explanation.
─Hey, mister compulsive smoker, could you give me a cigarette too? I brought you a can of beer.
The voice comes from my older sister, Chris. Apparently she deduced that she would be here, to have a little time alone to organize my ideas. Just like she said, she brought a can of beer for me that she put on the edge of the roof to my right.
Chris snatches the cigarette box from my pocket along with the lighter; and she starts smoking with me.
Siblings who spend enough time together are said to tend to share traits and habits with each other. At some point I ended up hitting these bad habits on Chris, so this is all understandable.
「Kssh」 -. The refreshing sound of a beer can being opened.
I take the cigarette out of my mouth for a moment to take a drink from the Heineken. The respective flavor of this drink is a very pleasant one for the palate once you get used to drinking it.
Smoking and drinking, well, even though it's just a can, it's still a bad combination.
At least that way I can clear my mind a bit and think more clearly about what happened...
...
...
...
Wait.
Chris studies Astrophysics... if there is someone who should be well informed on the subject, it could be her, right? Tell me if I'm wrong.
...
No. I am not mistaken.
─Chris.
─What?
I have a question. It is only hypothetical but I would like you to answer it seriously.
─Go ahead.
Well. Now that I put it in the bag, it is time to throw the ball.
I have my doubts about this, the truth is that I am thinking that I am absolutely crazy but I consider that the best of the current case is to ask someone who has a better clarity of things than I do. In this case, my older sister is that person.
─If there was a person who lives in the middle of a series of time loops, how would that person know that they are in them? And hypothetically speaking with the same subject, what would produce it?
─Huh? Why are you asking me about science fiction? That is both physically and statistically impossible.
─It's true, it's true. But I still want to know, please, you are from Harvard, you should know how to argue simple science fiction theories with real science, right?
─Not because I'm from Harvard I have an answer to everything, you idiot... but, I have an idea. Listen carefully.
My older sister started with her explanation. As we looked down at all the people coming and going in New York, we held our conversation.
─To begin with, a time loop is a space-time alteration that joins two different points in time, making the beginning of one the end of the other and vice versa. Spatially speaking, a time loop is a vivid example of Einstein's theory of relativity on wormholes. To put it in easy terms, a time loop is produced by the odd paradox in space-time.
I understand what it says. To put it in simple terms, it is like folding a sheet without creating a break in the paper and putting a tubular figure connecting the two points. It's that, more or less.
─Following the [Novikov's Principle of Self-Consistency] with the purpose for which it was made, then the [Time Travel Paradox] is resolved. But for this, it must first be shown that there is an event that caused this paradox or some change in the past that causes it, then the probability of that event is zero.
Instead of considering the typical models of paradoxes such as the [Grandfather's Paradox] in which a time traveler travels to the past and kills his own grandfather, eliminating a part of his parents and therefore eliminating the existence of the. But, the traveler himself would not disappear, but rather, he himself would exist in a different timeline but with many different details because one of his two original parents did not exist, in short, the traveler would not have killed his grandfather or missing.
Novikov uses a more favorable mechanism for mathematics with something simple to understand:
You hit a billiard ball into a wormhole and it travels back in time to crash into the old version of it; that way it would hit it, change its course, and prevent it from traveling through a wormhole in the first place.
I guess there is no more to explain, so I keep listening to my sister.
─Therefore, instead of being a common paradox, a time loop could be called a recurrence in space-time. But hey, it doesn't matter much since after all, if it's a causal loop, it's not like much can be done in the same way.
─Casual loop? -. I ask with interest. It is a term that I have not heard before.
─Ah, it's not too complex. It is only a paradox that is not paradox since its produced loop is self-coherent and therefore, there is no paradox. -. She explains.
So that follows the same principle of self-consistency that she has already explained.
Due to the influence that a time traveler has on the past, it is understandable that the butterfly effect is applied. Nevertheless. In the special case of science fiction, this term "causal loop" is used to define why when the time traveler in various works of this genre, travel to the past and alter it, they would not be rewriting what has already happened, but rather, playing their role in what is already known and therefore not making any kind of change.
─So, if we follow the model that we have up to now. A person can travel to the past, however, he cannot do anything to change it, right?
─Well, you're 50% wrong and 50% right.
─Why...?
Chris tosses the butt of the finished cigarette and pulls another cigarette out of the box she stole from me. I also do the same with mine.
After the change of tobacco to consume, and a couple of shared drinks from the same beer can, we continued the conversation.
─In itself, a paraconsistent logic must be applied in all its splendor to validate what is known as [Self-fulfilling Prophecy].
A paraconsistent logic is a system that tries to treat contradictions or paradoxes in an attenuated way. Since time travel is full of infinite variables, then a type of logic that "agrees with inconsistencies" is necessary to have an objective point of view about the problem.
Regarding the self-fulfilling prophecy...
The sociologist Robert K. Merton formalized the structure and consequences of it in the book Social theory and structure, where Merton himself gives the following definition:
Self-fulfilling prophecy is, at first, a false definition, which awakens a new behavior that makes the original false conception of the situation become true.
In other words, this goes a bit hand in hand with Newton's "Action-Reaction" law, since according to Merton's concept of a "self-fulfilling prophecy" it explains that people do not simply react to what things are like. situations, but also, to the way in which they perceive such situations and therefore, their behavior is fundamentally based on their personal perception of the situation and the meaning that it attributes to the situations in which they find themselves.
Therefore, putting these two ideas together entails having a tolerance for any type of abnormality presented in human behavior according to the self-fulfilling prophecy. Connecting all the points, then I am making my own summary.
However, there is still something that bothers me.
─Chris, if we are talking about a self-fulfilling prophecy, then we are saying that...
─Exactly. In such a case, free will is not an option. What happens is according to the laws of causality and chaos theory.
The flapping of a butterfly in Brazil can bring a hurricane to Texas, huh...
In that we are already entering an increasing complexity. I understand every word perfectly, but I know that there are still many things to mention.
─Time travel has an interaction with hyperspace, right? You know, going from the third to the fourth dimension is imaginable at this point.
Hyperspace is a simple notion about everything that surrounds us.
• 0 dimensions corresponds to the point.
• 1 dimension corresponds to a line.
• 2 dimensions correspond to a plane.
• 3 dimensions corresponds to space (from 3D, which is all we perceive)
• 4 or more dimensions correspond to one (or more) hyperspace(s).
Oh well. We are talking in terms of physics and of course my sister has something to say.
─In part. The light always goes to the future. Therefore, if we take it that way, then it is logical that all matter always goes forward. The only way to travel in time is something that has not yet been demonstrated and logically it is travel at superluminal speeds or never better said, faster than light itself. Here I will quote a little a man that I admire. Physicist Michio Kaku observed Euler's beta function and raised under consideration that if we add a fifth dimension to the four already known, which are three spatial and one temporal, it is possible to propose a theory that in its best example, postulates that all equations corresponding to the light and the gravity would be united, in a theory of the Kaluza-Klein type.
...
But if we speak in those terms...
─The existence of black microholes, huh?
The more I think about it, the more I think I've really lost my mind to insanity. But hey, it is worth trying to decipher the enigmas of the human mind.
It's ridiculous, ha.
How could something like time travel be possible?
The existence of something like a micro black hole has not been proven, therefore, trying to defy the laws of space-time is just a wrong thinking of man.
─I haven't finished speaking yet, why does it sound like you've reached a conclusion? I have yet to answer your second question.
Oh, true. I already have a solution to the main problem, which led me to the simple conclusion that it is impossible for there to be time loops, we reached the point where you are going to explain to me how it is that a person who lives in those loops would be able to remember it.
─It's not that difficult. I will explain it simply with this example that I found on the internet, so... imagine that you are that person who lives in the loop. We already said that what happens in a loop is already written, there is no free will unless you exert reverse causality, but it does not matter.
─Aha... And what's the use of imagining it?
─That's what I'm going to do. Listen carefully to my words and apply it. You are the one who lives in the loop, the human mind has billions of kilobytes of information in the brain and of course you will not be able to keep your memories in their entirety, but sooner or later, there will be some remnants.
?
─Remnants...?
─Fragments of memory from other loops. They wouldn't be too big, but they could still be a huge help if you live in a loop. Well. Let's continue with the example... How much is the success rate for an event postulated in the [Law of Really Large Numbers]?
Ah, about that.
I remember reading it a while ago.
─In 1 out of 1000 occurrences, then the result is 0.1% with just one trial. This only applies with an unlikely but not impossible event.
─Perfect. That said, the probability that such an event will not occur on the first attempt is 99.9%.
That's right... it is.
And therefore, in a set of 1000 independent attempts, the probability that it does not occur in any of them is 0.999¹⁰⁰⁰ = 0.368, or also expressed as 36.8%. And therefore, the possibility that this event occurs at least once is 1 - 0.368 = 0.632, or rather 63.2%.
─If we present it in the same way, then the "unlikely" event has an occurrence of 99.9% after 10,000 repetitions. The human mind would not be able to perform these 10,000 repetitions between loop and loop, after all you are still the same person no matter what changes occur around you. A person living in the loops shouldn't be able to find out that he lives in one unless it is revealed from an outside source, however if the calculations don't fail me, when the trend of a single occurrence exceeds 99.9% of its 10,000 rehearsal repetitions, is when the remnants of the loop begin that will create sequences in the affected person (or people).
In this case, a maximum entropy is not possible, which establishes a less skewed probability distribution to which a statistical system can be attributed is one in which, given fixed conditions, it maximizes the entropy.
In short.
It seems that maybe the tile has moved a little.
