There's a great paper by Kip Thorne, _et al._ that shows a way to resolve these paradoxes without breaking time. The idea is that if an object's trajectory towards the time portal would cause a paradox, its future self emerges at a slightly different angle, so that it causes itself to enter the portal at that same altered angle instead of missing entirely.
I like to imagine this is how time travel would work in real life, a natural system that occurs in a way so that all the pieces react to one another in a way that they all fit together every time.
@@Connorses right if time ever would break itself, instead a force shows up changing the trajectory of what/who was going to break time instead to use that power to become that force that changes that trajectory. (like you creating a time machine but before you can use it, you show up from the future to warn against using it for anything other than obligatorily making the trip to warn yourself that you just received)
There's a game called Achron, which is an RTS with time-travel as a mechanic. It handles time-travel by using "time waves" that propagate along the timeline from past to future and carry changes along. You, as a player, play in a sort of meta-time, which gives you an overview of the playable timeline which you can look in at whenever you like. It's a bit complicated, but definitely an interesting kind of game.
That's cool! That's also how time travel works in Back to the Future, incidentally. It's why Marty didn't disappear instantly, and why in 2, old Biff was able to return to his own timeline instead of the altered future he created by giving himself the almanac
@@z-beeblebrox Similar, but not quite. The ripples in BTTF start when the change to history is made. The time waves in Achron are constantly and regularly moving up the timeline from past to future. You can clearly see their boundaries moving across the timeline in your UI. You can even avoid units being wiped out by time-travelling them over an approaching time wave.
@@z-beeblebroxWhile true, there's another reason why Hill Valley looked the same when old Biff returned to the future. Remember how he starts gasping and clutching at his chest when he arrives? That's because it continues into a deleted scene where he disappears (the ripple from his changes catches up with him there). And the answer to that, as confirmed by the creators, is that one day Lorraine finally had enough and shot him dead. I suppose he didn't end up making as much impact as he'd hoped, with the entirety of future Hill Valley remaining unchanged after Biff's reign and death.
I found your channel today and, I have to say, I'm surprised you don't have more subscribers. Your content and delivery are top notch. I guess the topic is just a bit too niche for the algorithm to pick it up.
I’m not sure if you still check these videos, but I loved the initial demonstration of traveling to the past through portals. It reminded me a lot of outer wilds, and I was curious if that was a source of inspiration
@@TodePond without any real spoilers besides how the game handles this one weird interaction. The game runs the physics of an object forward to predict where it will be and show it there. It's in a very contained environment when they have to actually use it so there's not many ways to break it. If you turn off the time machine before the object travels into the "time machine" then it does break the game and give you a game over. There's a bigger example but I won't go into it.
I'd like to see a version of Branch where "Redundant" branches are faded 😄 For example, each Simulation with no frogs is identical from a causality perspective. By "closing" identical branches, maybe this will help keep the number of open timelines from spiralling out of control? Really cool video regardless! 🐸
That would be really cool! They could visibly merge together! I definitely want to experiment with 'closing' timelines more now, and that's a great idea for it. Thank you very much for watching too! I'm glad you enjoyed it! 🐸
Maybe when two branches have the same "fate" (there's some point in both their futures where all the objects are in identical positions and have identical velocities) it'll speed up or slow down one of the branches to make the two converge at the same time so it'll be easier to delete them?
yea! it's like, if we think of these branching timelines as objects in some kind of "worldline space", then timelines that play out similar would be close together. And timelines where essentially the same thing happens are basically in the same location. An infinite strand of almost identical universes, from which some could branch off at any point if a time travel arrives there. And to simplify the visualization, you just show one to represent them.
I implementing time travel in a game I made in a way kind of similar to the branching method, except each branch could only create one branch. All departing time travelers will arrive in a different universe, but they will all arrive in the same universe as each other regardless of when in that timeline they used their time machines. This can be implemented really easily by simply simulating the entire universe from beginning to end, removing any actors that time travel out of it, and then simulating it again but adding back those time travelers at the time that they wanted to arrive. Repeat until you end up at a universe that nobody time travels out of. This happens to work equivalently to that episode of Futurama where they use a time machine that only goes forwards, and discover that their universe repeats itself. Because in this way, backwards time travel is actually just traveling forwards one lifespan of the universe, minus how far back you wanted to go. As mine was a video game, the oldest version of the actor had free will, while all of the younger "time clones" followed recorded keyboard inputs. This can still cause a lot of chaos, as if one past version of the actor is prevented from time traveling, now in every subsequent timeline a different version of them will also go missing, eventually including the one that prevented them from time traveling in the first place. The grandfather paradox doesn't break the simulation, but it does cause enough confusion that I guess you could say it "breaks time."
I loved this video because I have always loved the idea of time travel and the many different ways it's done in fiction. also I love how you made the video "restart" that was the best part in my opinion :)
Great implementation! Time travel/control in physics engines is the coolest thing ever! Thanks to the youtube algorithm for recommending me the video I've been looking for as long as I can remember!!
how about this idea: there are two types of frog: normal and anti the energy and mass of an antifrog is exactly opposite to that of a normal frog when a frog and antifrog are combined, they are instantaneously combined into nothing when traveling to the past, both a frog and antifrog are created in the same space (which cannot interact with each other), meaning that a net of 0 energy/mass has been added. let's call this new frog a neutral frog, or nog. supposing the frog actually makes it through, it and the antifrog part of the nog are combined into nothing and the frog of the nog is left free if it doesn't make it through, you now have a frog and a nog which adds to 1 frog worth of mass/energy because the nog has none. if two nogs collide, they are both destroyed because each half of one destroys the halves of the other. when an antifrog collides with a nog, the result is an antifrog when a frog collides with a nog, the result is a frog
Sorry to interrupt but I've only now realized that this is not time travel. This is actually time travel. A better example of this would be...*time travel* I love your humor
There are lots of interesting things here. Though personally I can only find the "branching timelines" model plausible at all. It just seems like paradoxes absolutely wouldn't be allowed, but at the same time you can't just have arbitrary restrictions like "if you're gonna cause a paradox (how does the universe know) this portal is now a solid wall". Instead, time travel isn't real, and you're just transported into a copy world where everything LOOKS like you've traveled back. I can't imagine the Nexus thing either, just because again you can't really tell in advance if a paradox will happen... it's just a simplification to avoid an actually closed loop spawning infinitely many nearly identical worldlines. But they're still all separate, right? The question remains how a single finite person travelling back through time could possibly cause an entire clone universe to be created! but maybe that's also just a conceptual simplification. Well if we move away from game engines, where we expect the player to have some real-time control, there's also the possibility that all of spacetime has been laid out from the start: in such a way that even if movement backwards is allowed, it just happens to never cause any paradoxes. Some kind of equilibrium state, where even uncaused time loops would be possible. Sadly this doesn't translate at all into a game that can be controlled, unless there's a way to recalculate this equilibrium depending on user input... that seems expensive though.
hey i did code this for real, so "if you're gonna cause a paradox" is definitely possible to figure out :) all the code is at github.com/TodePond/TimePond
@@TodePond that's true ig. does it work by simulating into the "future" and deciding based on that? because it seems like for that to be reliable you'd have to simulate pretty far (like, maybe something doesn't directly cause a paradox, but its past effect causes a different frog to start off a chain reaction that obstructs the first frog in the past?)
@@ilonachan it projects into the future, and then projects how it would project the future's past (ie: the present). if the new present is different in any way, then we know that it's impossible
lol! At beginning: Welcome back, to the SandPond Saga. one minute later: Welcome back, to the SandPond Saga. two minutes later: Welcome back, to the SandPond Saga. a moment later: Welcome back, to the SandPond Saga.
my personal theory is just that time is multidimensional with at least 2 dimensions, so that when you're travelling back in time you're not ending up in a situation that interferes with what already happened for you but an entirely different state of the entire universe
Another implementation would be the idea of vacuum energy and use it to create another frog through the portal, just as a quantum fluctiation. But this borrowed energy cant last very long so the frog disappears. Basically going into a portal adds vacuum energy and coming out of one subtracts vacuum energy.
OH you should do one where when going through a portal branches time, every portal travelling frog exclusively gets its own branch. Yes it breaks time faster but that way you'll NEVER have paradoxes, since the frog never interacts with itself
Haha yeah it was much smaller back then! And yeah I was trying to lead into a Tenet-style one for the PondSand Saga section. I got like, halfway there, but ran out of time
in my opinion there's 4 key types of time travel (0-3). only 2 of which appears to cause a paradox. type 0. destiny trap. events of the past can not be changed. any attempt to change the past has already failed, else we would already have found time travelers. "one often finds their destiny on the path they takes to avoid it". type 1. time has fixed points. facts. things that are required to happen. be them cosmic scale events or miniscule quantum ones. the "curve" a timeline follows MUST pass through these points, maintaining tangent to the point. the rest of the curve can be any of the infinitely many quantum permutations where changes have inconsequential results on the outcome at these points. similar to type 0 in that one can not know if they have altered the past because simply knowing what happenes/happened defines it as a fixed point. only where there was already uncertanty can you force a single option (and thus creating a new fixed point). in this way you can change the past, but you'd have limited ways of verifying it was changed and thus usually appears identical to type 0 from any first person perspective of the timeline. type 2. retrocausality. the future affects the past as much as the past affects the future. time does not care about cause and effect on the grand scheme of things. it is a continuous hyperstructure that has its own shapes and rules and geometries. like a (true) klein bottle is impossible with just 3 dimensions time itself is part of the shape. it can fold back on itself creating apparent paradoxes from our perspective but from a hyper dimensional standpoint simply represents an arbitrary "knot" in the geometry. what appears impossible to our linear intuition is perfectly viable and does not self contradic. type 3. fluid time. like a river that never knows where its been nor where its headded we each follow the contuors of causality. divert a river up stream and it will wither and fade or change form and shape. time paradoxes are serperfluous and either are inconsequential or non destrictive. moving from one river to another does not negate your past, but the place and time you originated no longer exists, replaced by something new or changed; like the ever flowing river they constantly shift and bend on their own naturally. you cant return to the exact timeline you started from. at best you will travel to one with only infinitely small differences.
one thing that'd be ez to do is just a cellular automata with portals that can't go further back in time than how long it takes to cross the distance between them, so no paradox
i noticed that you said you would play outer wilds in the comments of this video a few months ago, did you do that yet i love that game and i was wondering what you thought of it if you have gotten around to it yet, also your videos are really cool
I derive immense pleasure from the act of viewing the captivating and intellectually stimulating production entitled "Top 9 Ways to Make Time Travel." As I immerse myself in this extraordinary audiovisual experience, I am treated to a meticulously curated compilation of the most intriguing and imaginative methods proposed for traversing the fabric of time. The creators of this remarkable piece of media have undoubtedly invested considerable effort and ingenuity into crafting an insightful and entertaining exploration of the concept of time travel. Each of the nine featured ways, no doubt accompanied by expert commentary and visually compelling illustrations, serves to fuel my imagination and ignite a sense of wonder, as I contemplate the possibilities and implications of bending the temporal boundaries that govern our existence.
just a reminder: math is a logic system that helps us prove things about our real world. the fact that we can do all of this with math says something about our reality
If there was time travel, I don't believe a paradox would be possible, I think that rather than not being able to we just wouldn't do it, not out of caution though.
So, what about the simplest solution: determinism. Time travel can be possible but what goes on at every point in spacetime is fixed in each solution of the equations of motion. Each solution is consistent. Supposedly inconsistent things that “break time” aren’t actually solutions of the equations of motion. Just pick one of the solutions and feel utterly, not surprised at all.
@@murdey Not sure how to interpret that "Hmm" ^_^. My description was quick and also, stuff like "equation of motion" is of course jargon. And what I described is not one unique hypothesis either, since there is still a lot of free details. But even so, if you have any questions about what I mean, I'd be happy to elaborate a bit.
@@TodePond that's fair; in my personal case i just plucked it into a media player with a "force mono" setting and already watched it, but accessibility is an important thing to have, so better late than never i guess
Walking. Running. Flying. shuffling. Waving. Moving in general IS time travel. You just see this kind. If it were spatial or quantum it'd still be movement but unseeable.
You create a broken universe with those kind of rules that allow someone to create an "alternate timeline" where they never accomplished what was an obvious start of your successful time travel into the past. The energy used in the attempt to thwart yourself would cause a reaction of your future self to jump out of the way, right? I would have a muscle memory of performing the act of trying to jump into my own way, and I would think that the universe would simply delete the problem by making the act of interrupting yourself result in your time travel into a one way trip via a black hole into the terribly distant future; by the time hawking radiation caused the black-hole to evaporate, you'd be emerging into a new universe much like you did when you came out of the big bang in the first place. It's an odd thought to think that the creator created eternal life literally. It just takes forever for it to happen, makes sense, right?
These video's from you are really unique and awesome. But time travel into the future is possible and predicted by Einstein and physically tested. There hasn't been one scientist in the planet that has proven Einsteins Relativity theory wrong in any way either. It's just that you or something is always somewhere and not duplicated by some portal mechanic. We don't just step in a machine and go into the future but gravity does effect fine in a very significant way. Traveling to the past is another thing, we constantly view the past (light beams that travel to our eyes and are perceived by our brains) but cannot make changes in it. But again, I'm really enjoying your videos. Keep making them.
Thank you very much! I'm really pleased you are enjoying my videos! Time is so interesting, and time dilation is so cool. I think that time in the 'real world' works quite differently to how it does in my little physics engine :)

Some kind of equilibrium state, where even uncaused time loops would be possible. Sadly this doesn't translate at all into a game that can be controlled, unless there's a way to recalculate this equilibrium depending on user input... that seems expensive though.

type 1. time has fixed points. facts. things that are required to happen. be them cosmic scale events or miniscule quantum ones. the "curve" a timeline follows MUST pass through these points, maintaining tangent to the point. the rest of the curve can be any of the infinitely many quantum permutations where changes have inconsequential results on the outcome at these points. similar to type 0 in that one can not know if they have altered the past because simply knowing what happenes/happened defines it as a fixed point. only where there was already uncertanty can you force a single option (and thus creating a new fixed point). in this way you can change the past, but you'd have limited ways of verifying it was changed and thus usually appears identical to type 0 from any first person perspective of the timeline.
type 2. retrocausality. the future affects the past as much as the past affects the future. time does not care about cause and effect on the grand scheme of things. it is a continuous hyperstructure that has its own shapes and rules and geometries. like a (true) klein bottle is impossible with just 3 dimensions time itself is part of the shape. it can fold back on itself creating apparent paradoxes from our perspective but from a hyper dimensional standpoint simply represents an arbitrary "knot" in the geometry. what appears impossible to our linear intuition is perfectly viable and does not self contradic.
type 3. fluid time. like a river that never knows where its been nor where its headded we each follow the contuors of causality. divert a river up stream and it will wither and fade or change form and shape. time paradoxes are serperfluous and either are inconsequential or non destrictive. moving from one river to another does not negate your past, but the place and time you originated no longer exists, replaced by something new or changed; like the ever flowing river they constantly shift and bend on their own naturally. you cant return to the exact timeline you started from. at best you will travel to one with only infinitely small differences.
That was overwhelming. Since mass and energy are one thing, if you have enough energy you can make a new particle, same thing about the frogs.
A criminal lack of mention of Dave Strider in these comments D:
Jokes aside, loved the video!
I love you’re videos
Oh neat, it's my old pal, the YOU DESTROYED THE FABRIC OF SPACETIME ending!
one thing that'd be ez to do is just a cellular automata with portals that can't go further back in time than how long it takes to cross the distance between them, so no paradox
Genius, great video!
Thank you! Thanks for watching it!
i noticed that you said you would play outer wilds in the comments of this video a few months ago, did you do that yet i love that game and i was wondering what you thought of it if you have gotten around to it yet, also your videos are really cool
My god, this is now my new farorite channel !
make one frog stop entering the portal if the frog sees its clone, but if it doesn't, then don't enter the portal
yo, i've seen you, you're the guy from a good place, you've got the time key i believe
What if you did some sort of B Theory approach? Visualizing time a physical 3rd or 4th dimension in which everything exists as a line which changes.
I derive immense pleasure from the act of viewing the captivating and intellectually stimulating production entitled "Top 9 Ways to Make Time Travel." As I immerse myself in this extraordinary audiovisual experience, I am treated to a meticulously curated compilation of the most intriguing and imaginative methods proposed for traversing the fabric of time. The creators of this remarkable piece of media have undoubtedly invested considerable effort and ingenuity into crafting an insightful and entertaining exploration of the concept of time travel. Each of the nine featured ways, no doubt accompanied by expert commentary and visually compelling illustrations, serves to fuel my imagination and ignite a sense of wonder, as I contemplate the possibilities and implications of bending the temporal boundaries that govern our existence.
Love the Video, Its interesting. and i know i'm a bit late to the party.
I think the fade out version works best
8:14 Woah the frogs slowed down time across all the timelines, by making too many timelines. How does that work?
just a reminder: math is a logic system that helps us prove things about our real world. the fact that we can do all of this with math says something about our reality
i''m going insane from this video.
what was this taken out of? there are several videos spliced together here it seems
If you mean the repeated intros that's just a stylistic choice this channel uses (presumably emphasised due to the subject matter)
What are you talking about? There was only one intro and time never broke.
Pin of shame
@@aaronking2020 lmaoo yup
8:34 14 different time travels?! What? 🤯
My mind is broken.
I'm just slowly losing my sanity as I watch this...
Have you tried the Peabody and Sherman anti paradox tactic where if one touches themselves thats a paradoxs and impossible so both are made as one
If there was time travel, I don't believe a paradox would be possible, I think that rather than not being able to we just wouldn't do it, not out of caution though.
Can you make this timetravel area public?
Pond pond pond pond!
Is this the theory that inspired Tenet? Am I gonna get temporal pinsired?
Where can I find the 3D simulations like at 0:15?
edit: nevermind, I just found the BIG Sand video
So, what about the simplest solution: determinism. Time travel can be possible but what goes on at every point in spacetime is fixed in each solution of the equations of motion. Each solution is consistent. Supposedly inconsistent things that “break time” aren’t actually solutions of the equations of motion. Just pick one of the solutions and feel utterly, not surprised at all.
Hmm 🤔
@@murdey Not sure how to interpret that "Hmm" ^_^. My description was quick and also, stuff like "equation of motion" is of course jargon. And what I described is not one unique hypothesis either, since there is still a lot of free details. But even so, if you have any questions about what I mean, I'd be happy to elaborate a bit.
These are cool :)
Thank you! 🕶️🐸

...ow, why is there a stereo effect on the voice, it's hard to understand and there are no subtitles either
it's for the ASMR lovers :)
and because I love *you*, I just added some subtitles right now!
@@TodePond
that's fair; in my personal case i just plucked it into a media player with a "force mono" setting and already watched it, but accessibility is an important thing to have, so better late than never i guess
If i just comment on a small creator vid, will i always get response? Cool video btw, the rewinding thing with variation is so fascinating
You usually will on this channel! And thank you - glad you liked it :D
how do you rotate the portals?
im messing with the timepond and cant figure it out
Hey :)
check out the readme for some templates you can try: github.com/TodePond/TimePond
I really need to clean it up and add more though!
@@yellowbox7065 drop an orange ball on a portal
Walking. Running. Flying. shuffling. Waving.
Moving in general IS time travel. You just see this kind. If it were spatial or quantum it'd still be movement but unseeable.

7:23 This reminds me of TenəT
Hmmmm, What happened to the original thumbnail why is the frog yellow
It's a variant from another timeline!
@@TodePond I swear the frog was red
@@officer854 woah you're right! also I swear it was called "SandPond Saga", not "Sandpond Saga" 🤔
@@TodePond hmmm
Repetition legitimizes
You'll see me next time? Or perhaps you'll see me last time :O
Where is this cool engine it looks cool and fun
i also like sand pond sgaa
I wish I could time travel to protect myself but I don't have thr power
You create a broken universe with those kind of rules that allow someone to create an "alternate timeline" where they never accomplished what was an obvious start of your successful time travel into the past. The energy used in the attempt to thwart yourself would cause a reaction of your future self to jump out of the way, right? I would have a muscle memory of performing the act of trying to jump into my own way, and I would think that the universe would simply delete the problem by making the act of interrupting yourself result in your time travel into a one way trip via a black hole into the terribly distant future; by the time hawking radiation caused the black-hole to evaporate, you'd be emerging into a new universe much like you did when you came out of the big bang in the first place. It's an odd thought to think that the creator created eternal life literally. It just takes forever for it to happen, makes sense, right?
These video's from you are really unique and awesome. But time travel into the future is possible and predicted by Einstein and physically tested. There hasn't been one scientist in the planet that has proven Einsteins Relativity theory wrong in any way either. It's just that you or something is always somewhere and not duplicated by some portal mechanic. We don't just step in a machine and go into the future but gravity does effect fine in a very significant way.
Traveling to the past is another thing, we constantly view the past (light beams that travel to our eyes and are perceived by our brains) but cannot make changes in it.
But again, I'm really enjoying your videos. Keep making them.
Thank you very much! I'm really pleased you are enjoying my videos! Time is so interesting, and time dilation is so cool. I think that time in the 'real world' works quite differently to how it does in my little physics engine :)
Time travel to the future is easy to simulate: just change the speed of time.
How do you rotate the portals in the website
Я наткнулсч на твой канал и, я должен сказать, я удивлен что у тебя не так много подписчиков. Контент и твоя подача на высшем уровне. Я думаю, ткмы, которые ты берешь в видеороликах, через чур нисшевые для алгаритмов.
Очень жаль, что ютуб не пробвигает такой контент и вам приходится делать контент такого уровня на такую маленькую аудиторию.
Why can you only release five versions?
I broke the others by accident when I was making the more complicated ones at the end :) woops
@@TodePond Oh. Would it be possible to re-code them, or would it be too much work?
@@AstroEli133 someone could look back through the repo history to find a fixed version, but i don't have time to do that currently
@@TodePond Oh.
Please make the different frogs public
Variations:
Sandpond Saga
Sand Pond Saga
Sand-Pond Saga
Sand PondSaga
PondSand Saga
SandPond Saga
How about Stein's Gate style time travel? I bet that's simulatable
You missed the easy one, the past is immutable.
