Time Travel in Fiction Rundown

[@thatxmas]

An entire video on time travel without using the word 'paradox'. Congratulations.

[@iceoriental123]

He talked about the grandfather paradox

[@Rikomag]

That's probably because paradoxes aren't really interesting when you're analysing time travel like this video does. The video is about how time travel DOES work (within these fictional worlds), not about how it doesn't work. Often, time travel paradoxes as they exist in fiction are the result of mistakes by the author, not by the maybe inherently flawed nature of time travel.

[@unstoppableExodia]

Well he didn't touch on the terminator franchise so it should have been fairly easy for him to avoid mentioning paradoxes

Doctor is very occasionally logically consistent, with future selves being already present with selves, but mostly each jump alters the timeline and creates a new path. I think the new conceit is that the Doctor, and the TARDIS start from a place outside of the timeline, meaning there should be no possible for the Doctor to influence their own timeline, except when they do. The doctor's companions get imbued with a quasi-timeless state while traveling with the Doctor

[@aneonfoxtribute]

One of my favorite examples of time travel, and in my opinion the best example of time travel, comes from Steins;Gate. There are three methods of time travel in Steins;Gate: D-Mail, Time Leaping, and physical time travel. With a D-Mail, you send a text message through time, which has the possibility of changing the past. If the change isn't big enough, then functionally nothing will change (for instance, if the thing you tell someone to do is minor or if they just ignore the text), but if it's big enough, you can change a lot. This is a large part of the plot, the characters sending text messages to the past and it enacts huge changes. For instance, in the story, someone plans to leave, and you send a D-Mail to them telling them to stay, and they will which causes massive changes. Nobody remembers anything from a D-Mail except for the protagonist Okabe. With Time Leaping, you mentally jump back into your past body from the future. You can only jump back 72 hours, and obviously because of this restriction you can only jump back three days before the machine was created. The person who uses the machine remembers everything, and the timeline changes just by virtue of your future knowledge. If someone other than Okabe were to use it, however, Okabe wouldn't notice any timeline change under normal circumstances, unless whoever it was did something so big that it forced the timeline to change. But time leaping itself wouldn't cause the timeline to change on its own, it's what the Leaper does with the future information that would cause it to change, With physical time travel, it's exactly what it sounds like. You travel back with your physical body. No changes are enacted on the timeline because the timeline already takes into account the fact that you have/will travel back in time, like Harry Potter. All of this revolves around the Worldline system. Every change made to the timeline takes them to a different Worldline. These Worldlines are shown on a little device that shows you exactly what Worldline you're in, but for the most part only the numbers after the decimal point change. To change the ones place of the device, that requires an absolutely massive change, one large enough to change the entire trajectory of the world. However, the worldlines revolve around several points that happen no matter what. No matter what you change, no matter how you turn back time, there are several points in history that will always happen no matter what. The main plot of the story is that one of the characters is fated to die by the worldline, and Okabe's attempts to save this person's life in the completely fucked up timeline that he inadvertently made, requiring him to revert every change he made in the story. Fate literally contrives this persons death. Even if Okabe does everything perfectly and gets this person in a position where they cannot possibly die even by mistake, they'll just drop dead with no discernable reason. It's SUCH a good example of time travel, and it manages to prevent paradoxes perfectly by just saying "It's another Worldline!".

TBH the time travel concepts of Steins;Gate are not that super unique. They are widely used rules. But the way Steins;gate sticks with their rules and their skills in explaining it though the story makes it one of the best shows I have seen

[@Real_MisterSir]

It's also equally interesting in the Harry Potter type time travel, that the time traveler effectively has no free will over whether they will commit to the time travel or not. It is their fate no matter their conscious thoughts, they will perform the action. And that also ties in well with the HP universe's use of prophecies, which also imply that free will to a certain extend is blurred. Potentially free will exists, but all thoughts and decisions will still lead to the same outcome - like throwing a stick in a stream - Its path down the stream may be random, but it is a certainty that it will flow down through it one way or another. It is confined chaos.

[@shellnut]

The game Outer Wilds has probably my favourite depiction of time travel ive seen recently (huge spoilers, go play the game first) Similarly to Groundhog Day, the main character seemingly relives the exact same 22 minutes over and over again, retaining all their memories of past loops. We find out later in the game that there is effectively a time machine linked to the main characters brain that is repeatedly sending our own memories back in time 22 minutes to their past self, creating the illusion of a time loop where in reality they have consious memories of things they have not done yet.

[@smitty7510]

endless loop,huh?

[@Twisted_Code]

the "no free will" point about Harry Potter is exemplified perfectly in the movie when, without any explanation or discussion, Hermione suddenly grabs the pebbles that she throws through the window of Hagrid's house. While it could be said that she would've reasoned out a solution to cause their past selves to leave the house regardless, it could alternatively be said that she had that "Eureka moment" BECAUSE she had already seen the results of it in her personal history (the vase breaking). It's utterly brilliant, and surprisingly, it's also completely realistic. According to the Novikov self-consistency principle (as described by Wikipedia; academic discretion is advised) "if an event exists that would cause a paradox or any "change" to the past whatsoever, then the probability of that event is zero". In other words, you travel to the past because you traveled to the past and you do what you already did, and no more (nor less)

[@ari54x]

It's less "no free will" and more "deterministic, single-timeline time travel." Hermione still decides to throw the pebbles- but she does so because she's worked out in the moment that this is what saves her in the past, and anyone in Hermione's particular set of circumstances at that moment would have done the same. Likewise with Harry having the confidence to cast a fiendishly difficult spell because he *already knows he did it.*

[@michael32A]

Except the vase/pot breaks into different shape/size pieces the two times we see it break. 🙊

However the problem with this is it creates the predestination or bootstrap paradox

[@kloggm4874]

@@ari54x It's not just no free will, it's no will at all. No conscious. In the movies, everything happened already. In the present the stone has to fly perfectly into the vase. Someone with free will or even "non-deterministic" abilities could have missed. But if you think about that... you will notice that when things have already happened, not just the person going back in time has no free will, also the person in the present has no free will, since the person will have to use the time machine at the perfect time in the future and everything must go according to plan. Actually, no one around has free will... because if they acted differently, just a tiny bit, maybe things would go otherwise and we got a paradox. Then there is the problem of: Who decided that he or she wants to use the time machine? It's already happened, they have to use it. So basically, someone in the future must have decided that. Here we arrive at the bootstrap problem. So it must be "fate". Fate decides that something happens. Again, no free will here, folks. This is a major problem. On the last part I'm not sure (I don't know the full movie), but from what I've read, it's also not really single-timeline. It's infinite timelines. When Hermione throws the stone, they are the future, but there is again another version, that is the past, which is the future to come. After them, there has to be another version, which is the future to come and so on.

[@ari54x]

@Klog GM none of this is a problem from a deterministic point of view, the loop happens exactly the same way whether you're on the pre-time travel part of it or the post-travel one. Harry casts his spell because his memory of being saved and realization he's the one who resembles his father makes him confident enough to do it, because that is the best choice a person with his temperament, memories, and body would make under those circumstances. The 'loop' is pulled off because they were always inclined to make the right choices to pull it off, not because they coincidentally choose the same things every time. This is exactly how we would expect time travel without parallel dimensions to work, in a deterministic universe. (which afaik all evidence points to our actual universe being) A person inclined to be discovered by returning late or to die after travelling back in time wouldn't make a loop where their 'future' self replaces the past self. They'd just die after rewinding, instead.

[@agalychniscallidryas7760]

I enjoyed SO much the trivia, freddiew was the first channel that genuinely blew my mind for their effects.

[@komplettichselbst]

I personally love the time travel mechanics of Homestuck. It follows the self-consistent loop principle to such a degree, that free will is _theoretically_ preserved, but deviations from the basically predetermined actions result in a branching of the time line and the new branch subsequently becoming 'doomed'. This means that the extremely intricate web of interwoven time loops which in the Alpha time line resulted in the creation of the universe and these loops is disrupted so that it _doesn't_ result in its own existence. So the doomed branch gradually fades away, in almost every case accompanied by everything going wrong and everyone dying one way or another until reality itself dies. Of course, this gets wildly more complicated as soon as alternate universes and other shenanigans come into the mix, but that is the gist of it.

[@RileyIsntDead]

Grzzlwmpf The definition of Homestuck: Shenannigans.

[@BranoneMCSG]

Woah that's cool as. So it's bacially like string theory, but every universe which made the 'wrong' choice is eventually destroyed?

[@komplettichselbst]

Branone Exactly! What's also interesting, is that it really is 'true' branching, in that you can jump from a doomed timeline back into the alpha before that branch. This happens a few times and is critical for the Alpha timeline, since the changes introduced by the influence of the doomed branch are actually required for the Alpha to exist

[@curious_one1156]

Check out Steins;Gate, a Japanese Anime, which, in my opinion, provides a very different method of time travel, by adding another dimension to it altogether (No spoilers here). Other than that, it maintains causality, and the act of time travel along with the flow of the present itself, creates the future, hence, time travel becomes necessary to preserve the sequence of events, just like in Harry Potter 3. Definitely worth watching.

[@juggling8557]

@@mia-paris5533 it's interesting because it underscores the whole problem with time travel. If at point A your partner dies, you decide, I'm going to go back in time to point A and prevent that from happening. But there's a problem. The thing that caused you to go back in time was your partners death. If you go back in time and fix it, now the event that caused you to go back in time... never happened, because you've fixed it. You understand? Prisoner of Azkaban leaves it as a paradox. Did buckbeak die the first time they lived through the event when the "thud" is heard of the axe? Or was that the executioner throwing down his axe in frustration? Harry and Hermione certainly assumed buckbeak had died, which is why they went back in time to fix it. But did he really die? Or had that event been fixed by their future selves already as they lived through it the first time? It's a way cool interpretation of backwards timetravel and excellent writing.

[@TheMadwomen]

It's stupid, imo. It's a paradoxical situation. In order to be able to travel back in time to save yourself, you can't have depended on yourself to save you. You have to get out of the situation first in order to get to the point where you could travel in time. Like, you can't depend on your future self to save you... If you don't have a future. Basically, since Harry and company couldn't get out of that situation without their future selves intervening, then they can't get to the time traveling method in the first place on their own. Therefore, they should all have died. A fixed time loop is one thing, but you can't just avert your own death in the past! Someone else has to do it because you won't be able to go back in time and save yourself! It's downright moronic, tbh.

My favorite time travel is from The Five Kingdoms series by Brandon Mull. After traveling back in time, you’ll find that the thing you thought you’d changed had actually always happened. In other words, it’s like Harry Potter’s time travel, except with one key distinction: you cannot travel to a time when you already existed, meaning that you can’t travel to the same time twice and can’t travel to any time that you were already born.

Well, technically, the Ministry couldn't have changed any of the past events in the series. Since time travel in Harry Potter can't change the past, if Voldemort had already survived up to the point where he was considered a threat, trying to change the past to kill him off would be useless, since the events that would have led to him surviving would already be determined.

[@drawapretzel6003]

Its kinda covered in the bit where they go through the ministry of magic time room, they only have so much of that sand, and presumably they use it exceedingly sparingly. Likely they *were* doing all sorts of stuff to change the "past" but nobody ever knew because that was already the world they lived in, where all that stuff already happened, all the stuff they made sure happened they just made sure to make sure that they went to make sure it happened. Like, voldemort didnt win. How many pin dancing angels were involved in making sure that happened? the world may never know, because it happens off screen, and probably for the best too. The series also has prophecy, so in some sense... theyre not constrained to retroactive time manipulation, they can manipulate time proactively as well, they just are very careful about what they do. We may never know how many times they sat in a blank room thinking up ideas and then slapping a button to see what the prophecy machine says the future would be, then going "man, that was a dumb idea, we all get nuked!" and then think up a different idea. I mean, with time turner consistent time travel, any time they actually needed advice from the future, one of them could just spontaneously appear and give them a note with the details, and problem solved, they then know that they have to go back and give themselves a note that its a dumb idea, regardless of if the dumb idea even happens... obviously if they tell themselves its a dumb idea its a dumb idea. I realize thats a bit circular but... thats how its always going to be when we deeply analyze unlimited time travel. Bootstrap paradoxes everywhere. Despite the fact that the ministry of magic is portrayed to the child audience as a bumbling pile of adult idiots manipulated by evil, there is far more politics and competence there than we ever see, simply because they are off screen and we are unaware of their actions. Also, dont forget in that same lab they casually have like... a gate to death? a passage to the literal afterlife, where all the non haunting ghosts hang out? i mean, who knows how many virtual war criminals they just yeeted through that thing, huh? They had time, space, death, i forget what the others were, but they had so many ancient magical artifacts down there that it is very likely stuff happened off screen we never knew about. Probably for the best.

The original Terminator was a good example of the "self-fulfilling prophecy" type of time travel where the events that take place were exactly what happened the "first time". I also like this type the best. The reason I don't like the ones where you can make changes as much is because it's too easy to fall into a paradox if a writer isn't careful. For example, if your future self goes back to stop yourself from taking a certain road to work. But if you were forced to take the alternate route without anyone knowledge about it then you aren't going to know to go back in time the "second time" to alter the path. So now it's a paradox.

[@Xunkun]

Yes, but you can still make it work even with the mess of the sequels. The tl;dr of my fantheory is: the version of how Skynet turned on humanity we heard from Reese _is_ accurate.... for the True Original. _But,_ the version they fought and won against just before the movie is _not_ Skynet 1.0. I like to point out that Skynet does seem more and more pre-emptively Evil with each new iteration we get of him: also smarter, more proactive, more creative, more advanced (as it's written up to catch up with real world technology, and the film's CGI budget). The version we heard about in the first place sounded like AI that just didn't have proper Oth Law coding/education, if he ever got some version of the 3 Laws of Robotics in the first place. Another thing I can't seem to re-find was a note from James Cameron, saying there's a version of Skynet that _won..._ and feels *remorse.* The rest of my fantheory is that this remorseful version of Skynet _is,_ in fact, the True Original. It doesn't have the emotional baggage of aggression, contempt and hate that, for example, the 11th Doctor version of Skynet displayed. So to complete my theory: the time war has been going on for *many* cycles _before_ the first movie, and that the True Original Skynet is the manipulator behind all of the Time Wars, with the goal of _helping_ humanity... or at least making sure we always have at least a fighting chance (it can't openly act, because it knows his later iterations are too powerful and in greater numbers for him to do so; or maybe it's too "far" away from how many cycles have occurred to directly do anything anymore). The most canon thing I can find to back this up? kzbin.info/www/bejne/l4a0gHykjLaZeq8 Pretty good match.

[@Daniel-wn3hd]

So my only issue with that kind of time travel is cases where the person going back saves themselves in the past. Harry Potter is probably the most simple example of my point. Future Harry saves Past Harry (and friends) from the dementors and ultimately allows Past Harry to become Future Harry and keep the loop alive. But how did Future Harry exist in the first place since, without him, Past Harry dies and is never able to become Future Harry. The time travel at the end of Interstellar is a similar yet grander example (future human race saving itself in the past). All of that said, I too prefer the kind of time travel where the past can't be changed, but it's also not without the potential for paradoxes.

[@1234andrewjacksmith]

The simple answer is there no original point where there was never two Harry’s because they can’t change the past with these timeturners is harry the very first as you called it was saved by himself because so the question how did past harry survive to become future harry was always future harry Like the reason they don’t get caught by the minister and co before Sirius even steps in to capture Peter is because of their past selves and it is what stoped werewolf lupin from killing them and the dementors from killing harry always has been that way, the future is just as fixed as the past, this Harry Potter time travel is also the same as what accurate prophecies when you can’t change them, like in the matrix, you have already made the choice now you have to understand it and no one can see past a choice they don’t understand Aka all the future choices have already been made you have just yet to make them and so the future is unchangeable just like the past because all the choices that made the world like that have already been made

This is in Primer too, but Primer takes it to an extreme and makes it nightmare where time travel overlaps over time travel and you have no idea what's going on anymore, though it seems quite clearly that there IS logic to it. It's just a twisted mess that we only get to see from one perspective. People start showing up who they never even told about the time travel device in the first place.

Cell made the strategic mistake of revealing too much about himself. He was so sure of succeeding that he didn't thought about blewing his future chances.

By the time Trunks reappears, that machine is rusted and Cell ready to intervene 5) Cell explains his backstory, revealing that he's a dormant lifeform that will, one day, kill Trunks and take his time machine 6) Both sides increase their power for the upcoming 1vsMany fight. As a safety measure, this timeline destroys the lab to avoid creating another time loop in the future. 7) Cell's intervention changes the timeline again and ends with his death, the discovery of the SSJ2 state etc. (DBZ arc epilogue) 8) Trunks return after the victory, and as he got stronger in the past he's able to destroy the meaner androids 9) Cell awakes and can't find android, he attack trunks to take his time machine 10) Trunks trained because of Cell Stage 3 and expects an attack.

The problem with time travel is that space is associated with time. For example, the solar system is going around the Milky Way galaxy at 1 million miles per hour, so what happened an hour ago took place a million miles away, and what happened one day ago took place 24 million miles away, etc....So if you travelled backwards in time you would also have to travel to the exact same point in space.

[@DeviilReaper]

My favourite time travelling type, is that once you go back in time and change anything you cause a new timeline, but that doesn't affect you in anyway since you are from another timeline, so if you killed yourself that is a different you and it does not mean you disappear its just the 'killer' you is now in a different timeline than originally was; it just makes it really hard to get back to your original timeline - if not impossible.

[@MichaelDeeringMHC]

Exactly! The instant you show up in the past the timeline branches and both timelines continue on. When you leave your original timeline you don't show up in its past but create a new line with you in it and there is no way to jump across from one line to another. So in the original timeline they see you disappear and not reappear in the past. You are just gone as far as they know. So time travel never really catches on. Which explains why we are not overrun by time travelers. The only ones that know that time travel works are the ones that go, and they can never get back to their original line, but just continue on in the new line. I've gone back to 1975 from 2040 eleven times, and this is the first time Trump was president. Time lines don't repeat exactly in real life like they do in the movies, quantum uncertainty, chaos theory, the butterfly effect, and backward traveling quantum uncertainty via the quantum eraser effect. Like Dr. Who says, a big ball of wibbly wobbly... time-y wimey... stuff.

I think one of the best time traveling devices is the one in Stephen King's book "11/22/63". In it, there can only be one time line. If you travel back in time and change something, when you return to the present, the effects of what you did take effect and you change the present. But if you travel back again to change something else, now everything you did in the previous travel didn't happen so now only what you change this time will take effect. Another cool thing about it is, that if you want to change small things that won't really affect the world (like going back in time to watch Star Wars when it came out, and then coming back to the present), it would be very easy to do. But if you want to change something major (like killing your father and prevent yourself from ever being born), somehow you will find lot's of hardships to do so (like your gun always jams when you go to kill your father, or you get hit by car on the way to kill him, stuff like that). That way, no time travel can "accidentally change the past". You must actively want to do it. And even then, when you change things, the world sometimes mend's it to go back to the normal timeline (like if you somehow manage to kill your father after many trials, you don't disappear because actually your mom was fucking the mail man and you were never your fathers son)

"time traveler´s wife" has the very best concept of time travelling ---much more better then the Harry potter one: 1. in "the time traveller´s wife" he always jumps into a part of future or past where he also is time travelling: so he never sees himself ( in film only one final exception), 2. he can´t controll when he timetravels or where he goes, and 3. he never can take any things with him on his timetravel: it´s only his own body& mind; so he can´t take things from future to past and so on....

I like the idea that time travel doesn't "create" alternate timelines; all timelines already exist, but by traveling back in time, you're actually switching to a timeline where that is what happened. So you can never change a timeline, but you can change the timeline that you're in. If by some chance you merely go back on the same timeline, then things will progress as before, like in the Harry Potter example.

[@Digitize27]

The Harry Potter form of internally consistent time travel might appear the most logically neat, but it somewhat ignores the completely illogical inconsistency when viewed from outside the time loop, the famous bootstrap paradox popularised by that episode of Capaldi's Doctor Who (Who write Beethoven's symphonies?) It creates a series of events that, logically, have no instigating moment, no 'start', a perfect loop with no beginning or end. Harry went back in time and ends up saving himself from the dementors because he saw his future self do so. The Harry that he saved will then go on to fill his role while he moves on in the timeline, and so on and so forth, eternally. But in this scenario there could never have been a 'first' Harry to go back in time, because without him going back to save himself, he would have received the dementor's kiss and been unable to. So while perhaps the most logically elegant in regards to not dealing with branching timelines, it is also one of the most infeasible forms of time travel, as it is a form of time travel that could never 'begin'.

[@zacw8869]

Exactly! I always disliked the Harry Potter time travel system because of this! Also the time travel system implies an oscillating system, as in a system that repeats itself, where every single atom in the whole world must be in the EXACT same spot with the exact same speed at the time of travel, which could just never happen on a macroscopic scale. Things in real life above the size of individual particals are too chaotic to oscillate like that in real life outside of microscopic objects. Like even if the time travel did start, it could never settle. It basically requires a god to have crafted the universe specifically with this exact time travel happening in specific places, which might be why it's so appealing narratively because the writer basically can act as this god to create a perfect scenario.

It's utterly ridiculous how potterheads defended at all cost how Time Turners can only establish predeterministic time loops and that's why Dumbledore cannot catch Pettigrew in rat form after he escapes, and then throw everything out of the window when the Cursed Child came out. Harry Potter is really an overrated piece of work as its author cannot even keep her rules of magic consistent, and instead makes up and discards new elements that are super broken whenever the plot demands. Seriously. Time machine, lucky potion, the unbreaky promise of death? All made up and discarded in the same book and never seen again (or in case of the Time Turner, has its rules violated complete when seen again).

[@kjn3350]

​@@doomse150That's true, but it's a very realistic depiction of how time travel would work. Assuming we don't go into some alternate timeline, things happen the way that they happened and the time travel is the reason why things happened in such a way. That doesn't mean to say that there is no free will, rather that things can cause themselves as a result of time travel and that the reason why things can't change is not due to a lack of free will, but rather that even when time travel occurs what happened happened, even if due to the time travel it is yet to happen.

Bill and Ted actually have pretty strict self-consistency, they just play with the concept pretty fast and loose, with the audience not being aware of what the characters are aware of sometimes, or a lot of the self-consistency scenes happening off-screen. For example, Ted's dad "lost" his keys a week prior to the characters realizing they needed it, so they just went back (off-screen and post-hoc) to when his dad did have the keys, stole them, and hid them in a nearby convenient spot for the characters to immediately find in the scene. Bill even mentions this explicitly, "Remember, Ted, we can't forget to actually do this afterward, or it won't have actually happened."

If Harry died and then time traveled back to save himself from dying, that would make no sense because how could a dead Harry Potter time travel and still function??

[@juIiska]

Ok, lemme get this straight. First, harry goes back in time to save himself from a dementor. But wait, he's already done that, or he wouldn't be there to save his past self. That means that the whole time travel concept is different, the butterfly effect basically does not exist in this universe and everything that happens is based on an algorithm that follows only one chain of choices, occurrences and events and doesn't stray from this path. Conclusion: the harry potter universe timeline concept is based on unchangeable fate and destiny, thus why the different timelines don't clash and everything falls into place.

Doctor Who Time Travel is actually really interesting! It, as well as the entirety of Doctor Who physics, will make a lot more sense to you if you just assume two things: first, time-travel is two-dimensional, with the first dimension being "in-universe time" and the second being "broadcast time", ie. events that are broadcast later overwrite events that were shown on television earlier; second, that reality is both sticky and discrete at a conceptual level. Consider Wedding of River Song. All of time, all of history is happening at once. So naturally the universe consists of a zero-dimensional point of pure energy. Nope! Things are still happening, people still live, physics still works ... but *historical events* overlap and are not progressing. That episode shows very clearly the level of resolution at which Doctor Who temporal physics operates - ideas, thoughts, people, entire cities; those things form the *atoms* of which history is made. You see this all over canon in a more subtle form - every time some object falls through a time rift whole instead of in tiny pieces, every time some item is used to create cross-temporal connections. Of course, what it actually means is Doctor Who operates on concepts as ontologically basic objects, as well as things like the law of contagion. It's *literally* magic.

[@istyleonu]

This is a perfect example of the typical Doctor Who fan. Just regurgitating words they've heard actual smart people use and in a way which displays that they really have no idea what theyre talking about. Just like most of what the Doctor says in the show. Go google what dimensions are. Something cannot be 2-dimensional if those dimensions are just 2 time lines. I know you wont be able to understand why, so let me explain it in terms you can understand. Time travel in the sense you are explaining would be like trying to flip on two different TV channels at the same time without having a TV...

[@FerociousMit]

I like the steins gate, John titor theory of world lines and convergence theory. Retractor fields and such. It just makes sense that way as well.

that being said, and also ironically they bash it in the movie, Endgame seems similar to Back to the Future's method. i.e. going to the past is splitting the time line and entering an alternate reality where you can make changes to it, only with no consequences to your own reality. As in if BttF was exactly like Avenger's time travel, Marty could've banged his mom and screw up that reality's Marty, and returned to his still crap present time with no problems. One of the few non paradoxical time travel methods in fiction, there's no this bit: 3:06, which has plagued the logic of backwards time travel since it was thought up. Also as Hulk puts it: "you can't change the past..." "going to the past, is *your* future..." It is consistent with this bit: 6:16.

Endgame is actually just multiverse/timeline jumping, like you are going to the past, but not your own past, because you weren't there your first time but you don't affect the future either, like it's two parallel identical lines that you jump between, but you jump to the other one at a different point, and then go back to your own at the same point you went back

Endgame actually does a really good job. Each time jump creates a new reality, it does not affect their past.

Cap going back in time to live with Peggy created a different reality/timeline and did not affect the MCU one. He traveled back to MCU timeline after Peggy's death to the point where he left. They kept the rules consistent and played it out really well, GJ on them

@@TheWhiteWolfFang Except, of course, they did create a reality where the GOTG don't form in prison, bond with Quill, and protect him from Ego, and a reality where Sitwell tells Pierce that Cap knows about Hydra. But yeah, it's a really simple Multiverse Theory.

The German series "Dark" is also an awesome example of logically self-consistent time travel

[@gilgamesh310]

Yes. That’s fantastic.

@Mutated Pearl Netflix and yes, there's a dubbed version

[@liliumdx]

@Mutated Pearl It's a Netflix Original, so it should be available in every country

[@spaztron5000]

DO NOT watch the dubbed version tho. You lose so much of the nuance. Trust me on this.

[@jedmaegraith8542]

Yes, very true, loves that series

I want to make content one day and one of my favorite topics is Time Travel in Fiction. I really enjoyed the breakdown of this video and I liked how you divided all the different ways the branches could go.
