That’s fucking horrifying, to be a living thing in that kind of system. It must taken those people millions of years to reach what we reached in 10,000 years due to all the resets. My heart goes out to whoever lives in those systems, even though it’s more likely than not that their life forms wouldn’t have the time to evolve into intelligent beings in those environments.
This timeline makes no sense. This entire simulation covers a few decades or centuries at best. There would be no time for a single civilization to develop before the system comes apart. Each orbit you see is an actual orbit, not a representation of thousands of orbits.
@@centrossect001 Well duh but this is meant to be representative of the 3 body game from the books so I need to destroy and rebuild at least one civilization. Besides we don’t know how long each orbit actually takes, so it might be much longer than an earth year.
Wow I didn't expect this repost to blow up suddenly on CZcams Fun fact: the original video on the Chinese platform Bilibili blew up when the (Chinese) Three Body TV series aired, and now it's the same with the Netflix one :)
You could try this again, but with the three main masses looking more like suns and the planet looking more like a planet. Maybe even you could have a way to keep track of how much light the planet is getting based on it's distance to the three suns, and from that calculate when exactly it's in a stable or chaotic era.
Came here after seeing the show because I wanted to know if the planet would collide into one of the suns in real life... But it turns out the reason the system doesn't last is something different.
I love how a star and the planet gets flung out at the end. It explains why 3 star systems are exceedingly rare, because after enough time passes, one of them would very likely end up ejected!
Yeah, perhaps... except these simulations don't seem to start in an orderly fashion, as real star systems do. Star systems form from an amalgamation of stellar gases in a disk configuration. This means 3 things: the stars formed would all be on the same plane and thus orbit in relatively equal degrees of eccentricity; the most massive star or the first one to reach a big enough size would become the center of the 3-body system and lead to a stable planet-like configuration for the other stars that would only change as the mass of the stars change over their lives (but probably never to the extreme shown in this simulation); and finally there would be barycenters between the 2 orbiting bodies that would serve as a center of orbit for the outside star. Essentially, 3-body systems (like Alpha Centauri IRL) are totally possible in a stable configuration given that they all form together (which I believe is how A Centauri formed). Another possibility was the capture of a rouge star, which then would account for the random nature of this simulation but would unequivocally end with the eventual collision of 2 of the stars. Obviously this has not happened and seemingly will NOT happen with Alpha Centauri, as the AB Centauri stars orbit the barycenter of the C star in a stable 79-year period.
@@mknote Yes but it's not really a 3 body system when it's stable. You'll have two stars that orbit each other in a center of mass and then the other star in the middle of it's center of mass
@@matthewcromer5399 By definition 3 body system doesn't have to be unstable. n-body systems are chaotic, because they can be both stable and unstable and we're unable to predict how they will behave. Actually we can calculate how any system will behave for any length of time, but in real life we can't get exact initial values, so our simulation will get increasingly less accurate with time.
I find it a little hard to believe that the trisolarians can build 11 dimensions super computers the size of a planet folded into the size of a proton but can’t simulate their star system movements.
Building a 11-dimensional supercomputer is actually easy for them, you just have to ram a bunch of shit into a proton. However, as scientists in the book have said, the three body problem has no answer, which means it is chaotic and impossible to predict.
Well three body system is what is known as a chaotic system, which means that even THE SMALLEST deviations in the starting conditions change the results drasticaly, especially with more time passing. That means that not only would they need to measure the masses and positions of all three stars and the planet at the same time and with absurd prescision, but also account for the smallest influences on the system, like other galaxies. The model in the video works and would work the same way each time because all of these variables are set prescisely, which is almost imposible in the real world.

Also, do you have a longer verson of the video? I'd like to know what happened to the planet and the yellow star as they went off the screen.
The planets go on to infinity after they went off and there's nothing interesting. The system fall into such state quickly regardless of the starting state (which I handcrafted) so it was very difficult to make the video longer. For planet POV I made this: czcams.com/video/ZbktsZJGau4/video.html The trajectories used in that video were made up though :( I haven't figured out how to merge these simulations.
@@i-fu9yg In an ideal scenario (computer simulation) with no perturbation the motion can be predicted by Newton's laws. However in real life there're inaccuracies like relativistic effects, gravity from objects outside the system and numerical error, making long term predictions extremely difficult, which is why we often call it random.
The issue with the premise that a super advanced race of alien beings coming to Earth because their system it's too chaotic, wouldn't occur. Naturally, a planet within a 3 body system wouldn't have enough time or chances to reach something like multicellular life. From our best understanding, life seems to be a consequence of random probabilities within nature that in the right conditions can produce complex life. A system with such chaos would reduce these probabilities from occurring in those conditions.
Idk the masses of the objects but if size is any indication this is more like a 4 body simulation. I wonder if the ejection time is inversely proportional to the number of bodies with similar mass. That could explain how the trisolaran system survived for eons.
How did so many civilisations of trisolaris spawn , that would have taken millions of years, by which time , either the planet or a sun would have been ejected or collided
I think that life may not spawn on a planet that definitely did not come to orbit the systems that definitely never formed a naturally occuring 3 body orbit for any meaningful amount of time before one was ejected. Badass premise though.
Well, technically yes, but I don't think the planet's mass is accounted for (and it is relatively negligible anyway). I think the purpose was to show what a planet orbiting a 3 body star system would look like.
No. But we would know how to set up the initial parameters of the system (velocity, position, masses) so that the 3-body system would remain stable for as long (or as short) as we'd want. Essentially we would be able to predict the 3-body system far into the future.
It’s hard to take a system with more than 2 bodies and predict the future with any accuracy if you don’t know the EXACT positions and velocities of every object. Like, if you’re off by a millimetre then your simulation might not be able to predict something a million years out. And we don’t even know the position of every object in our solar system to within a millimetre.
No, knowing how a system behaves is different from controlling it. This is literally Control engineering in a nutshell, and to make it simpler, to control a system you need to “write it” as mathematical model, usually we can simplify complex systems, we can get away with ignoring small effects that would make the model significantly more complex, or we can make sure a system is always on a certain stability zone, all of this to get a simpler approximation of the system and control it with some method. But if the system is chaotic, well, basically your F*kd
@@fakestory1753 there are stable 3 body systems but they are all specific scenarios, basically exceptions with an hierarchy order of masses or high symetry. Ofc this is not the point of the problem when we are talking about a ``3 body problem``
Here you are playing the symphony to the planet waltzing around the three suns... While Trisolarans are getting wrecked and destroyed by gravity countless times, going through stable and unstable eras...😁🤌
With time, even the slightest changes in the environment (or small errors in determining relevant parameters) could have huge impact on the accuracy of the simulated system. All the suns constantly gained or lost weight and speed. So without knowing exact parameters, all predictions would be probabilistic. Meaning, the slightest change in parameter value could determine which era would you end up in, chaotic or stable. And for the longer time you try to predict, the more probable is to f up with calculations.
Totally ignorant about the physics, but I’m wondering - Wouldn‘t there eventually be a collision, or at least some body drifting out of range eventually? Seems to me that a three body star system wouldn‘t be one for long.
These simulations don't seem to start in an orderly fashion, as real star systems do. Star systems form from an amalgamation of stellar gases in a disk configuration. This means 3 things: the stars formed would all be on the same plane and thus orbit in relatively equal degrees of eccentricity; the most massive star or the first one to reach a big enough size would become the center of the 3-body system and lead to a stable planet-like configuration for the other stars that would only change as the mass of the stars change over their lives (but probably never to the extreme shown in this simulation); and finally there would be barycenters between the 2 orbiting bodies that would serve as a center of orbit for the outside star.

Obviously this has not happened and seemingly will NOT happen with Alpha Centauri, as the AB Centauri stars orbit the barycenter of the C star in a stable 79-year period.
it’s because all of those outside influences are so far away that their influence is minimal, which is why the Alpha Centauri system can have 3 stars and even planets in a stable formation. The planets are much closer to their host star than the other stars in the system, so its orbit extremely closely approximates a standard orbit. Same with the two central stars versus Proxima Centauri on the outskirts, the latter is about 0.2 light years away, letting the two central stars have very close to a standard two body relationship. The perturbations are not nearly as dramatic as the system shown in the video, and will not be expressed in the lifetime of our star.
I’m sorry, where has this ever been observed or even divined to have happened in our universe? In other words, is this a purely speculative simulation or just a theoretical cosmological construction? I’d like to be informed about it if so.
No it’s exactly the same, that’s what’s so fascinating about three body systems, they are predictable but only if you know the exact initial conditions. So if you were around to see the creation of this system you would be able to predict it with 100% accuracy however if you were a lifeform that evolved on the planet it would be impossible for you to know the initial conditions and therefore unable to predict the movement of the system.
@@catgirlproductions7792interesting thing there. If it's simulated using Einstein equations and also compact objects like neutron stars or black holes, their trajectories are fundamentally unpredictable, i.e. they deviate from previous runs with the exact same parameters. Or so I read.
@@catgirlproductions7792 It's not the problem that they don't know the initial condition any condition could have been "initial" for there. The problem is that it's impossible to KNOW any condition - exactly - in real life. The simulation plays out the same every time because it's digital, the speed is 1000.99999 km/h exactly for example. In reality, the same speed is 1000.99999+error and there is no minimum error small enough not to cause an opposite result (than the one without the error), making the movements unpredictable.
@@catgirlproductions7792 not quite, "initial condition" does not mean that you have to be there at the beginning (what would that be? big bang?), but rather that you need to know the *exact* condition for a given time from which you want to start forecast the evolution of the trajectories. So it's more a problem of measurement accuracy of coordinates and velocities which always will have some errors
It's calles 3 body system, because the gravity of the planet is low enough for it not to count. For example the gravitational pull from the earth to the sun is extremely low, because they're so far from each other and the earth is big a magnitude lighter than the sun.
It could, but In this scenario it doesn't fall into one of the 3 stars because its velocity and distance are high enough to continually make a perfect balance between fall and escape
Wait, so the bugs NEVER figured this out, even when they managed to create 4 world sized super computers and then shrink them into the size of a proton?
It’s not possible. It would require calculating the effects of every atom in the Universe (because they all impact the starting positions of the planets). If any unpredictable event (like a simple spec of dust) enter their solar system over the course of a million years, then all their calculations would be off and they’d all die. Determinism =/= predictability, I suggest you read into “chaos theory” to understand more.
@@am.655. "Determinism =/= predictability" is such a succinct way of putting it - thank you! This is very useful to remember even for more abstract/philosophical discussions.
It’s in-figure-outable. when their star gets picked up by a the gravitational pull of another sun, there is no way to tell how much that change is gonna take and how their star will react.

However in real life there're inaccuracies like relativistic effects, gravity from objects outside the system and numerical error, making long term predictions extremely difficult, which is why we often call it random.
@@i-fu9ygthey’re not random. They’re chaotic.
The simulation is nice.
That's the epitome of chaos, supposing any form of life exist in such chaotic environment, how will it faire
Trisolarans punching the air rn.
There were times, when precise calculation of Mercury orbit seemed unresolvable.
I think another song fits perfectly for this is "Goodbye Moonman" from Rick and Morty
What kind of simulation program is this?
We'd like to congratulate you on your promotion from planet to starship
Is that mean there is no equation to describe & predict its movement?
I didn expect this ending
The issue with the premise that a super advanced race of alien beings coming to Earth because their system it's too chaotic, wouldn't occur. Naturally, a planet within a 3 body system wouldn't have enough time or chances to reach something like multicellular life. From our best understanding, life seems to be a consequence of random probabilities within nature that in the right conditions can produce complex life.
A system with such chaos would reduce these probabilities from occurring in those conditions.
Watching this blow up with the new Netflix show and I'm all for it!
Idk the masses of the objects but if size is any indication this is more like a 4 body simulation. I wonder if the ejection time is inversely proportional to the number of bodies with similar mass. That could explain how the trisolaran system survived for eons.
The planet's gravitational effects on the suns are neglected in the code, so it's in fact a 3 body simulation.
I like the political fan-fiction on this: Some-Body (else's) Problem
I hate it when this happens
if someone is on the planet, will the person be thrown out on the plant when the angular speed is change or velocity of the planet is changed?
Hahah nice question. If u figure it out tell me..

I understand why they want to get away from it.
The San Ti had no chance! 😆
Birth of rogue planets.
How did so many civilisations of trisolaris spawn , that would have taken millions of years, by which time , either the planet or a sun would have been ejected or collided
That thing that came through our Solar System. A few years ago, how did that effect The celestial mechanics of our solar system
That's a big planet
I think that life may not spawn on a planet that definitely did not come to orbit the systems that definitely never formed a naturally occuring 3 body orbit for any meaningful amount of time before one was ejected.
Badass premise though.
Will it finally evolve to a no body problem?
there are 4 bodies...
Well, technically yes, but I don't think the planet's mass is accounted for (and it is relatively negligible anyway). I think the purpose was to show what a planet orbiting a 3 body star system would look like.
Normally, a planet has below than 0.01% of star mass.
it can be ignore.
because a planet orbiting a two body star can have a stabile orbit.
Looks fine but I guess I'm just built different
So if a mathematical representation of a 3 body system becomes possible, does that mean we'll make a stable three body system?
No. But we would know how to set up the initial parameters of the system (velocity, position, masses) so that the 3-body system would remain stable for as long (or as short) as we'd want. Essentially we would be able to predict the 3-body system far into the future.
It’s hard to take a system with more than 2 bodies and predict the future with any accuracy if you don’t know the EXACT positions and velocities of every object. Like, if you’re off by a millimetre then your simulation might not be able to predict something a million years out. And we don’t even know the position of every object in our solar system to within a millimetre.
No, knowing how a system behaves is different from controlling it.
This is literally Control engineering in a nutshell, and to make it simpler, to control a system you need to “write it” as mathematical model, usually we can simplify complex systems, we can get away with ignoring small effects that would make the model significantly more complex, or we can make sure a system is always on a certain stability zone, all of this to get a simpler approximation of the system and control it with some method.
But if the system is chaotic, well, basically your F*kd
i don't know what are your mathematical representation
but there are already couple of stable 3 body system known
8 figure is one of them
@@fakestory1753 there are stable 3 body systems but they are all specific scenarios, basically exceptions with an hierarchy order of masses or high symetry. Ofc this is not the point of the problem when we are talking about a ``3 body problem``
No wonder the alien wanna get out of this sh*t
They can try cyberpunk so that they don’t have to consider the habitability of the planet for living things.
It's the first time i see a three body problem with four bodies

Deterministic chaos
Imagine having a Trisolaran as a manager and telling him you couldn't turn up for work due to bad wheather conditions.
Here you are playing the symphony to the planet waltzing around the three suns... While Trisolarans are getting wrecked and destroyed by gravity countless times, going through stable and unstable eras...😁🤌
If we can't predict it How are we simulating it correctly? Simulation is also a kind of predictions
With time, even the slightest changes in the environment (or small errors in determining relevant parameters) could have huge impact on the accuracy of the simulated system. All the suns constantly gained or lost weight and speed.
So without knowing exact parameters, all predictions would be probabilistic. Meaning, the slightest change in parameter value could determine which era would you end up in, chaotic or stable. And for the longer time you try to predict, the more probable is to f up with calculations.
do you get the same result every time?
입체로 보니 삼체인의 고충이 확 다가오네
Poor trisolarans :(
u say that until they invade us
There are four bodies!
Totally ignorant about the physics, but I’m wondering - Wouldn‘t there eventually be a collision, or at least some body drifting out of range eventually? Seems to me that a three body star system wouldn‘t be one for long.
Yes, eventually that would likely happen
Clearly that planet cannot sustain life
Three body problem with 4 objects? 🤔
Rogue planet on its way
When is the next stable era😂
С тремя звездами не пробовал, но эй, у нас как раз есть три тела: солнце, луна и земля.
four-body problem
Simulation means it is predictable
These simulations don't seem to start in an orderly fashion, as real star systems do. Star systems form from an amalgamation of stellar gases in a disk configuration. This means 3 things: the stars formed would all be on the same plane and thus orbit in relatively equal degrees of eccentricity; the most massive star or the first one to reach a big enough size would become the center of the 3-body system and lead to a stable planet-like configuration for the other stars that would only change as the mass of the stars change over their lives (but probably never to the extreme shown in this simulation); and finally there would be barycenters between the 2 orbiting bodies that would serve as a center of orbit for the outside star. Essentially, 3-body systems (like Alpha Centauri IRL) are totally possible in a stable configuration given that they all form together (which I believe is how A Centauri formed). Another possibility was the capture of a rouge star, which then would account for the random nature of this simulation but would unequivocally end with the eventual collision of 2 of the stars. Obviously this has not happened and seemingly will NOT happen with Alpha Centauri, as the AB Centauri stars orbit the barycenter of the C star in a stable 79-year period.
This is 4 bodies. Not 3 bodies.......
I do not understand how this is considered to be a " problem".
As you can see, it solves itself. Every . Single . Time.
How the heck do our planets are still on a stable track after being pushed and pulled like this for billions of years
it’s because all of those outside influences are so far away that their influence is minimal, which is why the Alpha Centauri system can have 3 stars and even planets in a stable formation. The planets are much closer to their host star than the other stars in the system, so its orbit extremely closely approximates a standard orbit. Same with the two central stars versus Proxima Centauri on the outskirts, the latter is about 0.2 light years away, letting the two central stars have very close to a standard two body relationship. The perturbations are not nearly as dramatic as the system shown in the video, and will not be expressed in the lifetime of our star.
I’m sorry, where has this ever been observed or even divined to have happened in our universe? In other words, is this a purely speculative simulation or just a theoretical cosmological construction? I’d like to be informed about it if so.
There are binary star systems in the universe so yes there are real planets that are orbitnig multiple stars.
So, 4 body problem then?
0:51 holy shittttt
So is the simulation different every time you run it?
No it’s exactly the same, that’s what’s so fascinating about three body systems, they are predictable but only if you know the exact initial conditions. So if you were around to see the creation of this system you would be able to predict it with 100% accuracy however if you were a lifeform that evolved on the planet it would be impossible for you to know the initial conditions and therefore unable to predict the movement of the system.
@@catgirlproductions7792interesting thing there. If it's simulated using Einstein equations and also compact objects like neutron stars or black holes, their trajectories are fundamentally unpredictable, i.e. they deviate from previous runs with the exact same parameters. Or so I read.
@@catgirlproductions7792 It's not the problem that they don't know the initial condition any condition could have been "initial" for there. The problem is that it's impossible to KNOW any condition - exactly - in real life. The simulation plays out the same every time because it's digital, the speed is 1000.99999 km/h exactly for example. In reality, the same speed is 1000.99999+error and there is no minimum error small enough not to cause an opposite result (than the one without the error), making the movements unpredictable.
@@catgirlproductions7792 not quite, "initial condition" does not mean that you have to be there at the beginning (what would that be? big bang?), but rather that you need to know the *exact* condition for a given time from which you want to start forecast the evolution of the trajectories. So it's more a problem of measurement accuracy of coordinates and velocities which always will have some errors
Yeah, that's a four-body problem. No deal.
Assume the planet mass is negligible
@@d9zirable agree
This four bodies … 3 stars, 1 planet = 4 😏
It's calles 3 body system, because the gravity of the planet is low enough for it not to count.
For example the gravitational pull from the earth to the sun is extremely low, because they're so far from each other and the earth is big a magnitude lighter than the sun.
Почему они не сталкиваются?
I don’t think collisions are a part of this simulation

How did life survive for the billions of years required for intelligent life to evovle?
Because our solar system does not behave chaotic over the observed served timespan.
@@clawer2969 I'm referring to the sci-fi series "3 body problem"
why i see 4 bodies ?
the white one is a planet
why no collision?
It could, but In this scenario it doesn't fall into one of the 3 stars because its velocity and distance are high enough to continually make a perfect balance between fall and escape
Why is this called a three-body problem when there are four gravitational bodies? Is it because one of them is not nearly as massive as the others?
It’s a planet orbiting 3 stars
yeah that's it
Wait, so the bugs NEVER figured this out, even when they managed to create 4 world sized super computers and then shrink them into the size of a proton?
It’s not possible. It would require calculating the effects of every atom in the Universe (because they all impact the starting positions of the planets). If any unpredictable event (like a simple spec of dust) enter their solar system over the course of a million years, then all their calculations would be off and they’d all die. Determinism =/= predictability, I suggest you read into “chaos theory” to understand more.
@@am.655. "Determinism =/= predictability" is such a succinct way of putting it - thank you! This is very useful to remember even for more abstract/philosophical discussions.
i thought they did figure it out, and the answer was that they were gonna die no matter what because of how unstable the system was
It’s in-figure-outable.
when their star gets picked up by a the gravitational pull of another sun, there is no way to tell how much that change is gonna take and how their star will react.
why is it considered a problem?
becaause days are unpredictable. years are unpredictable and you can come insanely close to two suns at the same time and get cooked.
Also the problem is predictability. You cant predict where all 3 bodies will be X time in the future.
i pity the santi people
But which is planet xD
