What is the three body problem? Neil deGrasse Tyson and comedian Chuck Nice break down why the three body problem is unsolvable and what makes it mathematically chaotic.
Is the solar system unstable? Find out about Isaac Newton’s worries about the solar system, Pierre-Simon Laplace’s calculus, and perturbation theory. Would a binary star system be chaotic? What about a star system with three suns? Four suns? Five? Learn about the restricted three body problem and how the Jupiter-Earth-Sun system could be chaotic down the line.

I don't watch a lot of TV so I didn't know this was going on. A colleague of mine ask me about the three body problem because she's a TV watcher. She wanted me to break it down. But the explanation ended abruptly because she doesn't believe the Earth is a sphere. It saved A LOT of time!

I think a simpler explanation is that when you stack too many rules, then you end up in a situation where it is too difficult to model with predictive precision because it requires parameters that continuously change, so you never get one single cohesive equation. I generalized the answer, because it applies to so many things in life beyond astronomy. But that's basically it. right?

​@@grimmspectrum1547 I think you missed their point. She's talking about the entery point of a subject. 3d modeling is a good example. So many kids want to make their own game characters and what not. Many even try. But the complexity and the headache of looking for the right content is a huge blocking point. If you find someone like Niel in the field you have interest in. It can bridge that gap and turn an interest into a life long hobby.

@@grimmspectrum1547What they are really saying, is that if the content is delivered in a hopelessly boring manner, you'll lose a far greater percentage of the audience right out the gate. This is especially true with many youths having short attention spans. They end up not being interested from not being engaged by the teacher, as opposed to the subject matter itself. My HS Chem teacher, was boring, went off on tangents off subject and said some borderline racist things. However much Chem he actually taught probably got tuned out by most of the class, myself included. No interest was developed or nurtured, yet other forms of media have made it more interesting in my adult life. I'm a professional computer nerd, that does enjoy learning. A better teacher may have opened my eyes to another pathway. I remember my chem teacher for all the wrongs reasons. Can't recall a single music teacher, and in spite of having limited interest in music as kid I started learning guitar myself as an adult. I'll probably never be a proper musician, but anything I've decided to try and become proficient at is self taught.

With a chaotic system with exactly known starting conditions we can model it forward for a decent period of time - infinitely or until the system dies with perfect inputs. The problem is that our accuracy of measurement isn't all that good, especially for distant stars. Then you have a big star cluster and "Oh no! Inaccurate measurements!" And then the system diverges wildly from prediction because no measurement can be good enough IRL.

Well, with spoiler alerts... It was all about the problem. The plan "they" had, at least. They just wanted the chaotic minds from Earth to show them how they do maths, to see if they could solve it. Then at some point they realised the chaotic minds will undoubtedly turn hostile, no matter what they did when they arrive. Unfortunately, they were already decades into their one-way trip to meet their trip to meet us chaos maths "geniuses". So, they declared war. Because that is apparently what a non-chaotic mind will do as it doesn't know any other way to respond. Since it is fiction, we ignore all the obvious plot holes along the way. Like, if they can lie about their appearance, why couldn't they lie about their intentions? Still a pretty good story, methinks.

I remember trying to tackle this problem in a senior level math class. It was a course on mathematical models, and we all had to pick some problem to present to the class. Someone did traffic analysis for highways, etc. It is so easy to state the problem in English, yet unsolvable. The system ends up taking 18 degrees of freedom (3 objects x 3 dimensions x 2 to count position and velocity) The final week of the semester, the teacher points me to a book that has the definitive mathematical proof that the system is unsolvable.

There's a different kind of 3 body problem in chemical kinetics. It basically says that simultaneous three body collisions are highly improbably, so they can (almost) be ignored, and chemical mechanism (nearly) always occur via two-body collisions, even if three reactants are involved. If three reactants are involve then the mechanism occurs via some kind of sequence of two-body collisions rather than by a true three-body collisions. Put another way, in chemistry, mechanisms that truly rely on the simultaneous collision of more than two bodies (which could be either atoms or molecules) are extremely rare. There's also a problem with unimolecular reactions, which are reactions that seem to occur without interaction of a second body. I won't delve much further into this problem here except to note that true unimolecular reactions are also rare. (This is unlike the problem of radioactive decay, which is like an ideal unimolecular reaction, not requiring interaction with a third body somewhere along the way.) There is something called unimolecular rate theory, but generally these unimolecular mechanisms rely on two-body collisions somewhere along the way, which activates one of the collicion participants into a metastable state that takes some significant time after the two body collision before something happens, which typically would be either an isomerization of a dissociation. Also, unimolecular rate theory usually applies to molecules containing more than two atoms because energy must slosh around the molecule in different ways before a statistically lucky event happens when the energy sloshes into motion that makes something interesting happen, such as the breaking of a chemical bond.

I think he missed an essential part. Why chaos (high sensitivity to initial conditions) means we cannot predict the evolution of a system over a long enough time frame. There are two reasons, one requires explaining the imprecision of numerical methods, so I understand that he didn't so this one. The other is because of imprecision in measurement and because we're not taking everything into account, which I find very intuitive.

Beautifully described. "You can calculate incrementally what's happening," but the system is chaotically dependent on conditions. Also, it's why even with the Sun, Earth, Moon system, Newton was unable to reliably solve the Longitude problem. This gets particularly interesting when resonance is added. Many of the planets (and moons) in our Solar System are in orbits that put them in resonance with each other. That very significantly delays the onset of chaos.

The predictive model is very sensitive to initial conditions as explained by Neil but also what catches up to you is that averages of forces over a time slice will also have some amount of imprecision and while each time slice will usually cancel out their imprecisions that is not always the case where you get streaks that cause precision to decline and that problem also grows over time as you calculate more and more slices of time where what are basically rounding errors start to skew the predictive results compared to the actual system being modelled.

I feel like this cannot be stressed enough: The problem here is that the "solution" is chaotic, it's not that the behaviour cannot be computed/calculated or by all practical means "solved". It's just that there is no NICE solution and that initial values matter a lot. So for instance, you can perfectly numerically simulate the behaviour of the entire solar system to predict the position of each object in like 10000 (or N) years provided you have enough infomation regarding current masses and positions. The system is still deterministic! it's not something like quantum mechanics where we literally can only predict probabilities. UPDATE: Ok, after reading the comments I realize that this being cahotic implies more than just "oh you just need to throw more computation at it". In order to predict the behavior of a chaotic system you need arbitrary precision for *each step of the simulation* and so the errors start compounding. This means that even using the most advanced computers that we could possibly build it wouldn't be enough to accurately predict the movement of bodies! (at least not with 100.00% certainity and of course specially when there are many bodies that influence each others equally) (butterfly effect).

​@@hoantran8654 No. Orbital systems are NOT always intrinsically unstable. Some are, and those particular orbits decay sooner or later, leaving those which are not prone to decay. At the present age of the universe, we don't tend to observe many of these systems, because they've already decayed. We ourselves happen to inhabit a planetary system which has remained stable for several billion years, which is several hundred million orbits on average. If it were inherently unstable, odds are that it would have decayed by now. But instead it happens to be one of those systems which are inherently stable. Mathematically you can think of it as a gradient which is concave up. An unstable system is concave down.

As usual, Tyson does a terrible job of answering the question and leaves people more confused than they were before. No, the issue isn't that 3 bodies move chaotically, it's that there is no arithmetic solution to the problem. In other words, there's no equation you can write were you plug in starting values and a time and get out positions and velocities for the 3 bodies. THAT is the 3 body problem, not anything about chaotic movement.

The thing is, a planet in a 3 star system like the Centauris would likely only orbit one star system, not be shared between them all. (The Trisolarans are from a planet orbiting the Centauri stars, but in reality Trisolaris would probably only be orbiting the Alpha Centauri AB system or Proxima Centauri [Alpha Centauri C]) Proxima Centauri has two known planets, Proxima b and Proxima d, while Alpha Centauri A may have a neptune sized planet in its habitable zone. Alpha Centauri A and B orbit far enough for A to have its own habitable zone, but close enough (in addition to B's much smaller mass at 0.9 Solar masses) that B does not maintain its own stable planetary orbit as far as we know. If Trisolaris is larger than Earth, its likely this Neptune sized planet within orbit around Alpha Centauri A, if its similar sized, its likely Proxima b in orbit around Proxima Centauri. Proxima b is an earth sized world and its within the habitable zone. However, Cixin Liu would have had no way of knowing any of this, as the first of these planets to be discovered wasnt seen until nearly a decade after the publication of The Three Body Problem, and neither would the researchers who came up with the scientific problem.

One of the most common approaches to solving the three-body problem is numerical integration, where the equations of motion for the three bodies are solved numerically using techniques such as the Runge-Kutta method or adaptive step-size methods. While computationally intensive, this approach allows for accurate predictions over short to moderate time scales.

In cases like this, "solution" means "an algebraic function that gives the future state given the current state and length of time." When you have such a function, you can do a LOT more kinds of analyses than you can when you have to run an iterative simulation. This was especially true before we had computers. A function that doesn't need to be simulated isn't chaotic. That is, if something is chaotic, you can't produce such a function. The element of chaos is what makes it impossible. (In certain cases, provably impossible. I don't know whether the 3-body problem is provably chaotic. You can prove a system is chaotic if you can prove that the term rises exponentially with time.)
