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.

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.

After reading 3 body problem, I'm curious, if trisolarean problems could be solved with planetary drives. Yes, 3+1 body problem can't be precisely solved. But unstable systems are chaotic only when they aren't tinkered with. Instability is neccesary for system to be controllable. So, if bifurcation points are calculated precisely enough, it should be possible to drive planet towards somehow comfortable traectory along suns, using relatively affordable amounts of energy. Or, at least, to make it more predictable.

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

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.

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.

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.

@@puppypalice 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.

@@puppypalice 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

because the mass of the planet is negligible compared to the mass of the three stars

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?

If they cannot be predicted then how can you do?

@mastershooter64 2 күн бұрын

It's not that they cannot be predicted. You can predict any system n-bodies that are gravitationally bound to arbitrary precision. They did this by hand 200 years ago and discovered a planet! (uranus or neptune i think). The problem is you cannot solve the equations describing the n-body system analytically when n > 2. The equations are a coupled system of differential equations and an analytical solution means you solve for it in terms of known functions or special functions. But that doesnt mean you cannot numerically solve this system of ODEs (ordinary differential equations). Numerical solutions for any differential equation is possible with the correct method and so that's how these are simulated. Actually an n-body system is quite simple to make (if you dont worry about precision too much) you can just use an Euler integrator or RK4 (they're algorithms for numerically solving ODEs). TLDR: we can predict them numerically, the only problem is we cant get a exact solution to the system, only and approximate one (but it's really a non-issue as you can achieve arbitrary levels of precision)

You know what prediction means, don't you, my friend? It's not a prediction, it's just positions on random possible movements based on probability.

@spacesweedkid27 2 ай бұрын

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.

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?

@aidanm.655 2 ай бұрын

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.

@OyunTireni Күн бұрын

It would have broken the system even more because it would not have destroyed the star, it would have made it worse. If we were to eliminate one or two stars or one sun through something like a wormhole, the planet's orbit would be completely disrupted and it would either fall out of the system or orbit the last remaining star, which would make life even more impossible.
