  • 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!

  • @larrybremer4930
    @larrybremer4930 Před 13 dny +20

    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.

    @Tordvergar Před 12 dny +8

    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.

      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.

    This tangentially reminds me of a discussion I once had with a co-worker, who refused to see any difference between _predicting_ an outcome of a process and _simulating_ the process through all intermediary steps until you reach the outcome. As far as he was concerned, those were _the same thing,_ and if simulation was too slow, you just needed a better computer, and voila: you get your answer almost immediately. That's what "predicting" something means, right?
    I finally was able to illustrate the difference by pointing to an analogue clock on the wall and saying: "What position will the hands be in, tomorrow at 15​:​30? You can answer that _directly_ from being told the time. You didn't need to imagine a clock going through all the minutes between now and then, sequentially, or take a real clock and spin its hands really fast to arrive at the answer. Your knowledge of the rules governing the motion of clock hands allowed you to _predict_ their position at a given time, without referring to, or even thinking about, any intermediary positions."

  • @thebuccaneersden
    @thebuccaneersden Před 8 dny +1

    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?

  • @lusvd

    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).

      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.

      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.)

      After the US UFO announcements the book by Liu Cixin rose in popularity. It's a dark forest story that's been adapted into a Chinese TV series & re-adapted by Netflix in the US this year.

    How does one submit a question with chance to be aswered in an episode? Is it Patreon based or here on YT?

    One starts out with very solid equations of motion for a pair of bodies right? Then you add one body more and the calculation becomes indeterminate which kind of goes against your intuition right because there's nothing nebulous about the equations of motion. Is there some deeper mathematical theory or theorem regarding this particular process going from order to chaos?

    So if you study hard enough and devote yourself to completely understanding the subject, you can become a Master Perturbation Theorist.

    Unfortunately, that series will not have a season 2 or 3 because it would be too expensive.
