The meeting yourself one is weirder than you think, because every time through the loop, the you who's meeting the younger you is a little different from the you who you met when you were the younger you, because you'll have the experience of meeting a slightly different older you. So it will be an unending loop of miniscule changes - but incremental and probably unnoticeable changes, not like the "back-and-forth" nature of the grandfather paradox. To illustrate. Let's say you go to the past, meet younger you and give the instruction, "when you get to be me, pass on this instruction to yourself but add one to my number. My number is 1." ... assuming young you honours the agreement, what happens to the number!
depends how it works, but no. Version a meeting version b, a is 'different' for having met b, sure, but that 'difference' isn't repeated infinitely, unless time is both alterable, and the time travel event is basically looping, somehow. Otherwise, some weird version of you visited, said their number is 1, but when you get to the other side of the convo, YOU HAVE TO SAY 1, because you already did. Nothing happens to the number. If it did work that way, it'd be branching timelines, and after the convo, shit's different, so there wouldn't be a guaranteed self referential loop, really. There wouldn't need to be a second future you, meeting a third past you. About the only way it works 'right' is multiverse, not time travel. Otherwise, from an outside perspective, it 'seems' to be a loop, but it's not. Just a string crossing over itself.
The speed of causality is instantaneous. Once the event takes place, it is history. The information concerning that event is transmitted throughout the universe at the speed of the carrier wave. You can outrun the pizza delivery person but you cant go back in time to watch the pizza being made.
Except the twin one, multiple timelines, temporal weapons/lottery, and temporal afterlife "paradoxes" which seem not to be paradoxes as much as just interesting considerations. The Schrodinger one seems to be a different paradox to me. Or is at least a unique enough perspective on the Grandfather paradox to constitute a significant reframing.
Are we not going to talk about how all of these were talked about and demonstrated perfectly in the TV masterpiece 'Dark'? Really hoping I'm not the only one here who's seen it lol
Addition to the bootstrap paradox/temporal inheritance paradox: You receive an infant puppy from an older version of you that went back in time. You raise the puppy until it is a year old. Then, you travel back in time to give the puppy away to the younger you. Now, how could the past you receive a newborn puppy, when future you gave away a year-old puppy? This applies to any amount of time spent by a bootstrap object. Whether 1 year or 1 second, the version of the object young you receives will age until you give it back. Now, from the perspective of the puppy, even if you only had it for 1 second, it would feel like it’s constantly travelling forward in time, and thus, aging.
Even more of a paradox is that eventually, the puppy will turn into an old dog and die, even though you were well aware that future you gave past you a living animal, not a dead animal body.
If you think first of the future you, he would have never had a puppy to give you because he would have never recived one. Now, the question is what would happen if you decided to buy a puppy and then give it to yourself in the past. Can you even try to give yourself something that you didnt ever recieved? Can you even look at your future you if he has no memory of himself looking at a future version?
@@CCABPSacsach what if instead of giving someone the same dog, or book, or whatever item, but you made a new copy each time? Both instances of the object would maybe exist at the same time, but the newer one always gets transported back in time
@@Catman_321 that’s a good form of time travel, but now the question is “how do we get a newborn puppy clone from a 1 year old dog” Unless, of course, the dog would turn into what it looked like one year ago, which would imply that going back in time [x] number of years will make you younger by [x] number of years. Which is weird, imagine going back in time before you were born. Would you turn into the stuff in the food your mother ate to make you? Or wait, this brings up the even bigger question: what counts as “you?” If your cells are always changing (dead cells falling off, new cells being made), and all your atoms are made using stuff you have eaten, you from a year ago was made of different atoms than you today, and you today are made of things you from a year ago has eaten. So going back in time this way, your atoms become… the food and water you consume? Weird thinking about time travel this way
Thanks for sharing. History is full of Bootstrap Paradoxes because there is a lot of stuff that happened are either stuff that can't be explained, coincidental, accidental, complete randoms, defies logic somehow or just random. So maybe this is how it happened in the first place. It already happened, just make it easier so it becomes more of a something.
I'm going to write a book based on all these paradox, there will be examples of each. Or.... maybe I already wrote it! Maybe you copied this from my future book!!!! You're in trouble now, I'll see you in court... unless I already have. Maybe you made my book a best-seller. In which case, thank you, UA-camr from the past!.
Okay, my brain started to turn to mush, but I didn't recall seeing the 'Phillip J. Fry' Paradox, where an idiot goes back in time and accidentally kills his own grandfather, but ends up sleeping with his grandmother, thus becoming his own grandfather. Also known as 'Doing The Nasty in the Past-y' Paradox.
Some of these paradoxes are just variations, examples, and implementations of the same paradoxes. It would be nice for the video to include examples taken from the movies. There are enough time travel movies and stories out here to provide these examples. Star Trek alone has numerous time travel episodes. So much that Star Fleet requires the teaching of temporal mechanics where Trek luminaries like Miles O’Brien and Janeway are very fond of.
99% of these assume one single timeline which may be the case but more likely it’s the Many Worlds or Everett Interpretation. Also as others have wisely pointed out in the comments but it bears a repeat mention - most of these are made up scenarios of the most basic paradoxes - so really repeats of the same concept. And weird combos of quantum physics like wave function collapse upon observations and the double slit and Schrödinger (thought) experiments indicating superposition. Kind of a stretch to claim the Fermi Paradox can be laid over time travel too. All in all though well done on the graphics and explanations though!
The Many Worlds Interpretation resolves nearly all paradoxes, even the Multiple Timelines Paradox. If a time traveler goes to the past, the mere displacement of space upon arrival creates a new timeline, with any and all possible permutations branching from that point. Conversely, traveling to the future causes the traveler to arrive in a timeline where their absence influenced events up until their arrival. In all instances, the traveler can never return to their original timeline, as it is virtually impossible to create the exact conditions necessary to return. You may be able to return to a near exact timeline, but you would effectively be an impostor to that timeline’s version of yourself. In short, anything goes.
My personal thoughts is it would create branched timelines. So if you went back and stopped something happening you would notice it in your timeline. youd have to stay in the timeline you changed to see the results
Examples: Grandfather: Marty redirects his mother’s affections to himself, _Back to the Future._ Bootstrap: Link learns the Song of Storms from the windmill guy, who learned it from Link, _Legend of Zelda: Ocarina of Time._
Thanks, this will be very useful for something I'm personally cooking :) Got a question for you, from your opinion.... Do you agree that... (Polchinski's, Future Knowledge, Temporal Communication, Time Travel Invention, Temporal illness, Temporal Inheritance, Temporal Artistic Influence, And finally Temporal Species Evolution...) Paradoxes. Are all just different FORMS of either the Grandfather/Bootstrap paradox? Meaning, ultimately they have the same problem --> Breaking Causality OR Missing Origin point. What do you think?
Basically, yeah. Nature of the beast. I mean, for there to BE a time travel paradox, the time travel 'event' itself has to be fucked with, to alter the 'start' of the event, for shit to get screwy enough to be a paradox...
i kinda feel like there should've been a minute or two explaining like, 6 ways time travel might work, then having a note on each paradox saying which type that falls under.
The grandfather paradox and its variations are only paradoxes when viewed through a certain lens. If you go back in time and kill your grandfather before your father is conceived you wouldn't cease to exist, you would simply be the guy who went back in time and killed his grandfather and your timeline would continue forward from that point, albeit in a different one from which you started. Actually you would have to kill your grandfather (or some relative essential to your conception) because if you did continue to exist there would be two of you, the second of which would go back in time and them three and suddenly an infinate amount of you which causes all sorts of problems.
depends how time works. Let's aay you go back, and cut kid you's hand and rub ash into the wound - do you develop a scar where there once, wasn't one? If yes, mutable timeline, and killing your grandpa prevents your birth, travel, and killing your grandpa - a fucked casual situation If no, some other situation. It's not really a paradox in that scenario. Funny thing about the 'new version of you' going back to the future, IN back to the future - there should be a doc and marty from that timeline, in that timeline.
I see a lot of repeats in these. A good third of them are just inheritance paradox. Another third are grandfather paradox rebranded and the twin paradox doesn't belong in this list
Travel back in time breaks the concept of causality by it's own. When you are able to move backward through a 4d space, then the observed cause and effects switch their order. Hm, probably have to rewatch Tenet :)
For me an underappreciated ‘paradox’ is that time travel in itself would be utterly useless without a complex element of space travel associated to it: If one travels only in time, but not in space, one would - due to celestial movements - invariably end up somewhere unintended. Most likely NOT anywhere back on earths surface….
As far as not being pestered by future time travelers, it still might be possible to do time travel or send messages to the past. But one could not go further back then when the time machine was first created.
Since accelerating is the key to time traveling to the future (because of time distortion), decelerating would be the answer to traveling to the past. However you cant decelerate past 0 therefore making it impossible to go backwards
I have a transmitter that can send information back in time, and a receiver that can receive such information. On Saturday night, just after the Lotto numbers are drawn, I use the transmitter to communicate the winning numbers to the receiver at 12 noon on that Saturday, which means that early in the afternoon I can play the winning numbers and set myself up for life. Under what circumstances could the use of this technology in this way create a time paradox? It would seem that if I transmit the winning numbers as soon as they are drawn, there would be no paradox. But what if I transmitted them eight days after the draw (assuming that the Lotto draw occurs every Saturday night)?
What I am positing is possible scenarios in which my use of the technology leads to changes in Lotto payouts to other players and consequent changes in the actions of those other winners if the size of their prize is changed.
The REASON you would send yourself the info (aka winning numbers) is because you were not, at that exact moment "set for life" (you hadn't won and only saw the winning combination after you played). If you send yourself the winning numbers, you would win, thus this past you (who continues to evolve in this new reality from that inception point) would have no reason to broadcast winning numbers in the past. Therefore, you never do... in the first place?!
Temporal timeline transportation Paradox: Will time travel events change instantly and cause time travellers to be trapped or would it create alternate timelines? Let's say that someone is sent in time 50 years into the past and it causes ripples in the events of the 1970's such as new music or political changes. Would the people in the 2020's instantly feel the change or would they be safely positioned in a separate timeline?
Time is either linear and actual time travel is not only impossible but an illusion. Or time is not linear and reality is an illusion. None of these paradoxes exist.
Exactly, it's just a change to the future, although the exception would be if the cumulative changes would have prevented the time traveler from traveling to the past in the first place.
Not a paradox really, but travelling through time as it is generally presented implies that the time traveller travels through time to (roughly) the same spot, but this doesn't take the incredibly long distance the earth/solar system/galaxy have moved from the "same spot" over that time.
And this is why time travel no matter which way you look at it. Is a tedious ability, that's why I prefer time manipulation. Like slowing or accelerating time instead
Time travel paradoxes are impossible without multi dimensional time. Just try to draw a paradox in comic strip where the character moves into a previous box.
not quite. It's more like, our perspective is limited. I mean, do you really think stop signs ARE red? That that's a property they have? Think about it, that's not how light works, hell, light only 'looks' that way to us based on the structure of our eyes and mental processes. Fuck, we don't even 'process' reality that much, the brain guesstimates and updates with new data. The illusion might be, there's no real 'past' or 'future', just a pattern seeking brain noticing differences ant connecting the dots to make a picture that doesn't exist, like constellations. Flipside - maybe time travel will exist, paradoxes can happen and nothing bad happens, because either 'shit don't work that way', being more than one 'style' of time, or reality just don't give a fuck if it doesn't make logical sense, shit just is.
Almost all of these are wither the grandfather or butterfly paradox is different angles Although all of them give new understanding of how time travel in general can unravel
Im fairly certain a good chunk of these paradoxes all fall under the same type of paradox and are just different examples and applications of the same thing.
About the Predestination Paradox... that case could theoretically not just create a temporal loop... Because as we know, time runs only in one direction so it can't repeat itself. It's possible that kind of paradox could create an entire parallel dimension where time is ingulfed and can just turn on itself. With events that continue to repeat for infinite. That's a kind of "time trap" where even the unfortunate creator of the loop can't escape... nor die, since his time just reload. He is trapped inside perpetually. Time travel is actually the true source of some of the most brutal horror scenarious human mind can conceive. We seriously should not build a "time machine".
Ok, hear me out. Isn’t it weird how we are both here watching this video randomly? Or maybe it’s not random, maybe we’ve been thinking about time travel, but we randomly started thinking about it and started watching videos on it. But isn’t it crazy how 2 random dudes that don’t even know each other decided to randomly watch the same video because we thought about the same thing just a day apart?
You forgot Niven's Rule of Time Travel Possibility: Presented (although probably with a slightly different name) in Larry Niven's essay "The Theory and Practice of Time Travel", it is this: If time travel is possible in a universe in which it is possible to change the past, then time travel will never be invented in that universe. This presents the idea that, if time travel is invented, some future time traveler will go back and prevent its invention.
Exactly! Travelling to the past creates a circumstance that will alter the initial need to do so. If you go back to prevent an event, then you do, then there is no need to go back in the first place and thus, you never do in the "first place". What is the "original" timeline then? Does such a concept even exist? Say I was looking at my wife from our bedroom while she was combing her hair in the bathroom. I KNOW she is alone there, from my perspective. Now... let's say I had the ability right then and there to go back in time 5 minutes, and join her in the bathroom.... what happens to the original "me/observer" that wanted to travel back in time in the first place since I never saw "myself" with her, originally, yet I clearly am and should technically always have been there, if I went back 5 minutes?
The democracy paradox would only be possible in certain countries/periods whose electoral process is flawed. In Brazil, due to the electronic voting machine, it would be impossible to vote twice in the same electoral process
Wouldn't "Paradox Self Correction" when it comes to this kind of thing cancel most of them out? I think the timelines where most people do the paradox foolishness die out till it hits a universe where you aren't a Paradox fiend. - I went back in time and killed or engaged actions that would kill my grandfather... thus, I wouldn't be born to kill my grandfather thus I never killed him, or replaced him. - I went back in time and met myself... I gave myself information to make better choices, however... because I keep going back and updating the info, my future gets better and better... Till it doesn't then all of it is undone.
Depends on how those changes propagate. See "Millenium" movie where paradoxes cause time quakes that physically destroy the future. Most time travel stories include discussion of the paradox blowing up the time traveler and his space time, so the self improvement strategy might be evolutionarily filtered out.
A lot of these were the same thing just in specific situations... I see the logic sure but then easily compare it to the original.. and it's the same damn theory
You missed one. The Hitler Paradox, in which a time traveler goes back in time and kills Hitler before WW2 starts, but in doing so prevents the need of doing so to exist.
These paradoxes are just useless, and as one the comments in the comment section said that must are just versions of grandfather paradox without grandfather, and all of these can be easily countered by 2 theories, the theory where no changes in the past is possible and the multiverse theory
@goldenalt3166 I mean yeah you are right mate, but that is the logical explanation to the question yk, there is no meaning in trying to make it complicated for no reason, because if you insist on trying to come up with a time travel theory without paradoxes is the same like saying what is in room if there is no light but the answer should not be darkness
@Poptrilogy In a sense, they are based on a faulty assumption that causality is only past to future and that it can be violated by time travel. Obviously, if time travel is possible then this assumption about causality is wrong.
@@Poptrilogy Time travel violates the assumption that causality is only in one direction. Paradoxes assume that it only works a certain way which is unjustified.

Not a paradox really, but travelling through time as it is generally presented implies that the time traveller travels through time to (roughly) the same spot, but this doesn't take the incredibly long distance the earth/solar system/galaxy have moved from the "same spot" over that time.
2 MONTHS AGO!! Ahh tysmm❤❤
And this is why time travel no matter which way you look at it. Is a tedious ability, that's why I prefer time manipulation. Like slowing or accelerating time instead
1:20 time traveler moves a chair the timeline:
I don't like the Novikov self-consistency principle. It suggests that free will is not an actual thing because time is written in stone.
i mean, scientists now, without time travel, say it's not an actual thing, too. I wouldn't sweat it too much.
There is a theory that time as we know it is an illusion. Could this mean time travel is possible without any paradoxes?
Time travel paradoxes are impossible without multi dimensional time. Just try to draw a paradox in comic strip where the character moves into a previous box.
not quite. It's more like, our perspective is limited.
I mean, do you really think stop signs ARE red? That that's a property they have? Think about it, that's not how light works, hell, light only 'looks' that way to us based on the structure of our eyes and mental processes.
Fuck, we don't even 'process' reality that much, the brain guesstimates and updates with new data.
The illusion might be, there's no real 'past' or 'future', just a pattern seeking brain noticing differences ant connecting the dots to make a picture that doesn't exist, like constellations.
Flipside - maybe time travel will exist, paradoxes can happen and nothing bad happens, because either 'shit don't work that way', being more than one 'style' of time, or reality just don't give a fuck if it doesn't make logical sense, shit just is.
There are a bunch of these paradoxes that can be merged together with other ones.
And then you have the "time travel paradox paradox". If time travel were possible, it would resolve whether all the paradoxes really existed.
Or more importantly none of the paradoxes exist if causality isn't strictly past to future and time travel itself proves that isn't the case.
If you go back in time 69 million years, any changes you could possibly have made would be erased 4 million years later.
Almost all of these are wither the grandfather or butterfly paradox is different angles
Although all of them give new understanding of how time travel in general can unravel
I was just searching on UA-cam. what came first the chicken or the egg? And I ended up here What A paradox 😂
Im fairly certain a good chunk of these paradoxes all fall under the same type of paradox and are just different examples and applications of the same thing.
About the Predestination Paradox... that case could theoretically not just create a temporal loop... Because as we know, time runs only in one direction so it can't repeat itself.
It's possible that kind of paradox could create an entire parallel dimension where time is ingulfed and can just turn on itself.
With events that continue to repeat for infinite.
That's a kind of "time trap" where even the unfortunate creator of the loop can't escape... nor die, since his time just reload.
He is trapped inside perpetually.
Time travel is actually the true source of some of the most brutal horror scenarious human mind can conceive.
We seriously should not build a "time machine".
Ok, hear me out. Isn’t it weird how we are both here watching this video randomly? Or maybe it’s not random, maybe we’ve been thinking about time travel, but we randomly started thinking about it and started watching videos on it. But isn’t it crazy how 2 random dudes that don’t even know each other decided to randomly watch the same video because we thought about the same thing just a day apart?
@LikeABoss1211 nah, it's just because there are no other videos about temporal paradoxes around.
One notable example would be Church from Red vs. Blue. I’ll give you a little hint: his next plan goes about as well as the first one. 🤣
Should put their movies or novel to give us examples.
I swear I’ve seen this video before, in 5 years.
Imagine Someone Put All Of These Time Travel Paradox That One Person Did All Of These Things In One Movie Man It Would Be So Chaotic😂😂😂
What about if you go back in time and do something your past self wont need to do it therefore you won't but then it wouldn't be done after you did it
You forgot Niven's Rule of Time Travel Possibility: Presented (although probably with a slightly different name) in Larry Niven's essay "The Theory and Practice of Time Travel", it is this:
If time travel is possible in a universe in which it is possible to change the past, then time travel will never be invented in that universe.
This presents the idea that, if time travel is invented, some future time traveler will go back and prevent its invention.
Exactly! Travelling to the past creates a circumstance that will alter the initial need to do so. If you go back to prevent an event, then you do, then there is no need to go back in the first place and thus, you never do in the "first place". What is the "original" timeline then? Does such a concept even exist? Say I was looking at my wife from our bedroom while she was combing her hair in the bathroom. I KNOW she is alone there, from my perspective. Now... let's say I had the ability right then and there to go back in time 5 minutes, and join her in the bathroom.... what happens to the original "me/observer" that wanted to travel back in time in the first place since I never saw "myself" with her, originally, yet I clearly am and should technically always have been there, if I went back 5 minutes?
given iit's not guaranteed, nor is there likely 'a' time travel creation event, eh.
The democracy paradox would only be possible in certain countries/periods whose electoral process is flawed. In Brazil, due to the electronic voting machine, it would be impossible to vote twice in the same electoral process
While interesting thought exercises, many of these are not actually paradoxes.
Such as the Butterfly Effect.
Outer Wilds spoilers:
Polchinski's paradox is the version of "breaking spacetime" that you you see in Outer Wilds at the High Energy Lab.
The way AI says par of ducks
Several where subject of Star Trek episodes.
Wouldn't "Paradox Self Correction" when it comes to this kind of thing cancel most of them out?
I think the timelines where most people do the paradox foolishness die out till it hits a universe where you aren't a Paradox fiend.
- I went back in time and killed or engaged actions that would kill my grandfather... thus, I wouldn't be born to kill my grandfather thus I never killed him, or replaced him.
- I went back in time and met myself... I gave myself information to make better choices, however... because I keep going back and updating the info, my future gets better and better... Till it doesn't then all of it is undone.
Depends on how those changes propagate. See "Millenium" movie where paradoxes cause time quakes that physically destroy the future.
Most time travel stories include discussion of the paradox blowing up the time traveler and his space time, so the self improvement strategy might be evolutionarily filtered out.
Every paradox in this video is invalidated by the parallel world theory
A third of these are not even paradoxes. You don't comprehend what a paradox actually is.
A lot of these were the same thing just in specific situations... I see the logic sure but then easily compare it to the original.. and it's the same damn theory
5:46 So COVID-19 was from future 😮
*COVID-69😎🙃
So... like half of these aren't paradoxes at all, and a solid 3/4s of the remaining ones are the same paradox repeated with different themes.
History abhors a paradox
You missed one. The Hitler Paradox, in which a time traveler goes back in time and kills Hitler before WW2 starts, but in doing so prevents the need of doing so to exist.
Its just the same as the grandfather paradox
These paradoxes are just useless, and as one the comments in the comment section said that must are just versions of grandfather paradox without grandfather, and all of these can be easily countered by 2 theories, the theory where no changes in the past is possible and the multiverse theory
Those are both not time travel.
@goldenalt3166 I mean yeah you are right mate, but that is the logical explanation to the question yk, there is no meaning in trying to make it complicated for no reason, because if you insist on trying to come up with a time travel theory without paradoxes is the same like saying what is in room if there is no light but the answer should not be darkness
@Poptrilogy In a sense, they are based on a faulty assumption that causality is only past to future and that it can be violated by time travel. Obviously, if time travel is possible then this assumption about causality is wrong.
@@goldenalt3166 Can you please elaborate of what do you mean by this?
@@Poptrilogy Time travel violates the assumption that causality is only in one direction. Paradoxes assume that it only works a certain way which is unjustified.
No evidence of a soul, so there's that.
Tid resa is only possible to parallel universes. End of discussion.
likes are perfect 777 i cant like it
Back to the future wore it better
Pretty loose definition of "paradox".
Comment
There's no such thing as a paradox.
Blah blah blah (pause) paradox
Yeah, many of these are just repeats of other paradoxes.
