Highly recommended the book "three-body problem" that is mentioned in this video. I read the Chinese version first a couple years ago, and it's just fascinating, especially the second of the series, which unveils a theatrical formulation (a.k.a. Dark Forest) of the interactions between civilizations in the universe. Although it's a sci-fi, most of what described in this series actually have scientific basis are within reasonable possibility. Anyway, the English version translated by Ken Liu is great in term of quality, still highly recommended if you can't read the original version in Chinese.

In my vision of that machine (I was still a kid), the Solar system's planet orbit a fixed setting as if an axle was lodged into the center (not the Sun itself nor the mass of the machine). The planets will act as a centrifuge while the sun provides solar energy. The asteroids and the other bodies floating within and around will be harvested and mined for their resources. Eventually the other planets will also become mined and harvested for their resources, their core or in theory will be used much like the sun or whatever properties energy can be extracted from them. At that age, I just discovered what an engine was and learned recently about the Solar System; I combined them in my head.

It's refreshing to finally see a video that discusses this. Unsolvable problems such as this one are really good reminders that our "knowledge" is not nearly as "certain" as we think, hope, or want.

If you like such a theme, also check out the "Halting problem" in theoretical computer science....

[@FinGeek4now]

They're not unsolvable though and you said it yourself, they are just really good reminders that our knowledge is not as certain as we think. We're missing other variables and maths to solve such problems.

[@johnmanno2052]

@@FinGeek4now That, unfortunately, is open to much debate. Far more debate than a comment section on KZbin could hold. In a very very small nutshell, what I mean by unsolvable is something that has no, and in fact cannot have, a final answer. Which seems to be most nontrivial problems, both material and otherwise.

[@FinGeek4now]

@@johnmanno2052 It's not a huge debate tbh, as we don't know what we don't know. Have someone put an object into a sealed box, then bring it to you. Your objective is to state what is inside the box without opening it or asking what it is, etc.. Quite the unsolvable problem? Not hardly, as anyone that can see in four+ dimensions will tell you exactly what is inside the box and then wonder how you cannot solve such a simple problem. Does that mean you'll never be able to perform the problem? Not necessarily - someday we may very well advance far enough down the technological path that we'll be able to have higher dimensional probes which can see in higher dimensions than what we are capable of naturally. In the case of the 3BP, we're missing something(s) and until we find what we're missing, we won't be able to solve the orbital dynamics. That is a far cry from saying that it is unsolvable and that it cannot be solved. A better qualified statement would be that, "The 3BP cannot be solved using our current models."

Even in a closed system (which is never the case), we have several other external factors/forces to consider: - other stars & galactic gravitation - star's fluctuation and life cycle changes (energy bleeding, CMEs, solar wind, etc) - background radiation and smaller star system objects (asteroids, comets, etc) - dark matter/energy (if they are a thing) - general relativity and space/time expansion - chaos theory (uncertainty principles say we cannot even measure that initial states of velocity and position with 100% accuracy, for any of the bodies!) - quantum mechanics may come into play on larger scales in some way (more RNG) So, mathematically, you can model a N-body system, but only from a perfect initial state/start point.

Very fascinating, honestly a reminder of how far we have come and how far we have to go. But on the topic of that experiment, I don’t think that we are unstable, or that insane unforeseen possible endings are so close to being real. I think that if it we were in a universe where Mercury was less than a millimeter away, we would have needed a whole completely different series of events for that to happen, from the beginning of our solar system, to our universe, to the beginning of time, in a way that it is and was physically impossible to reach that ending, that there was no way that Mercury could be 1 millimeter different, because if that were true the laws of physics would have had to be different, fate of cause and fate of circumstance in our universe seemingly with endless varieties but truly only one; the only reason we perceive free will and change is because of our limited perception of time and the respectively infinite amount of variables that go into every event of time.

[@clmBerserker]

" I don’t think " But thats the thing, just because you think it doesnt make it true. We dont know the future, and there are restrictions to what we can know. While its highly unlikley anything would happen(during out lifetime), be certain that it can. "the only reason we perceive free will and change is because of our limited perception of time and the respectively infinite amount of variables that go into every event of time" For free will, I am certain the major factor is the illusion of choice. As for change, what sort of change are we talking about, I change my underwere atleast twice daily but I'm guessing thats not what you mean.

Hey! Thanks! It was a composition made specially for this video. The link is here! soundcloud.com/imageaudio7/soundtrack-of-ted-ed-newtons-three-body-problem-explained-fabio-pacucci

[@xxprogressxx624]

This is the best explanation I've heard of the 3-body problem

[@anishhirlekar1033]

4:57 - Dehydrate! Dehydrate!

[@calciferlangary]

It's a chaotic era.

[@Gbtx6]

I'm glad this same guy keeps also voicing these videos after all these years. His voice is a staple to TED-ed videos ❤

[@mydeenraihan2152]

While watching TED Ed videos,always used to click like before it starts, because I am very much sure about the content quality and the knowledge being delivered to us through your videos will be informative and wonderful.

[@gringo1723]

NO LONGER TRUE...

[@MindsetInsurance]

The episodes on Netflix is so good. Who’s waiting for season two? ❤ ⬇️

[@tunkycool]

I have no idea what he's talking about but the music and animation are so calming 😊❤

[@risav202]

Just needed this, was reading about chaos theory and butterfly effect.❤

[@vishank7]

Do check out Veritasium's video on the subject! Is absolutely stunning.😄💎

[@prakharchaudhary9797]

I just heard of it in SAT physics.

[@Tymeshifter]

And the narrator tried his best not to mention it.

[@meenispham]

what's the name of the books?

[@androktasiai8185]

Me when our school suggests online schooling: " What? There's no way I would learn with that! It's too difficult!" Also me: *Listens intently at TedEd vids and actually learns a thing or two* "Aight.."

[@Skwertydogs]

All three books in the series are excellent. Even the unofficial fourth book "The Redemption of Time", a work of fan fiction, is a terrific read.

[@Cenourafnord]

Muito obrigado por postar um vídeo que aborda um pouco do problema descrito em um dos melhores livros que já li; "O problema dos três corpos". Estava sentido falta de uma explicação melhor e você apresentou muito bem nesse vídeo. Abraços

[@emmaccen]

3:27 is a work of art ❤

[@Gravitight]

@ 1:16 he says gravitating asses lol

[@IntoTheCinemaVerse]

😅

[@jlcjanes]

Who is here from Netflix?

[@t-rexreximus359]

😂✋ guilty as charged

[@sanhitaguin9683]

Guilty!!

[@andyc8704]

Gizza

[@mikelay5360]

It's not a coincidence. Netflix and Google share our information. How did KZbin know to recommend this video after I just finished binging on Netflix

[@jorgeblanco7504]

✋🏽

[@emmanuelgonzales586]

This brings the saying "two's a party three's a crowd" to a whole new level

[@Player-fp5xh]

i think this just proves how magnificent and strange our existence is. it seems planned, set into place

[@BaxterJaspurr]

Yes, this is more scientific evidence that it is the atheist who is irrational. A 1 mm change in a million mile orbit can cause havoc and there can’t be an intelligent being behind it all to begin with?

[@VietVuHunzter]

I highly recommend the trilogy "Three Body Problem", or "Remembrance of earth's past" by Liu Cixin for anyone who into sci-fi.

[@dennismoti9343]

Reading the first book now, super excited to see this.

[@ItsAustinSea]

Just binged the show on Netflix, now this is being recommended to me on KZbin Good to know Netflix is selling my data lol

[@karu6111]

It’s google

[@joelface]

It's an extremely popular show that just came out so a lot of people just watched it, and so a lot of people happened to look up videos on it. That dug up this video. People that watched the show are likely to click on this one, since it's from a TedTalk, which is interesting. So, I'm going to guess that they're just recommending this video to a lot of people right now, rather than that they bought your netflix watch history.

[@zhuangsj]

What is three-body problem ? Do not answer! Do not answer! Do not answer!

[@VickrantShindé]

How accurately or precisely are you ‘measuring’ or calculating the point of a center of mass for two gravitational masses

[@itsnlee]

Now the title of the Netflix show makes sense. I was so intrigued by the title.

[@nesha_owo]

came here cuz im currently watching 3 Body Problem

[@cyrus05w]

At 2:41 Knowing that Jupiter affects the rotational habit of the Sun I'm curious if you're going to mention the factor of weight. Or mentioned in the equation mass maybe.

[@brutexploiter]

Just gathering knowledge before watching Netflix’s 3 body problem

[@md.shihabahmed7558]

Same, haha😂

[@popnroc593]

here because of netflix

[@luismarques9736]

Me too

[@048elhambhuiyan8]

​@@luismarques9736 Me three

[@a.m.doesit9347]

😅

[@randomjasmicisrandom]

Yep.

[@JeffSans]

Same

[@RicardoTorres5]

2:25 That reminds me of a triple pendulum (look it up). I immediately got the picture of how messy and difficult to calculate it can get vs a double pendulum.

[@exx8eran]

The video contains contradictions. The problem is not that there are "open variables" to the system (as otherwise it wouldn't have been deterministic and 2 system with the same known parameter would have been able to cnverge to different solutions). the problem is that we don't have an analytical or not computational cheap way to solve it currently. And because the chaotic nature of the system, inaccurate data might lead us to a really wrong solution.

[@adamlahaie723]

I was thinking the same thing, if there were too many unknowns, it wouldn't be possible to solve it numerically, but it is. I think they oversimplified that part

[@luftstolle]

Yeah, I don't know anything about this three-body problem, but I don't think that can be correct. There is no mention of that on Wikipedia either. That makes me think that the author is not an expert in this, and makes me highly sceptical of "Ted-Ed" in general. I also doubt that the current solar system, if accounting for just internal gravity, will destabilize within 5 billion years with a probability of anything close to 1/2000.

[@cookiedoe6068]

My phone must be listening to my bf watching Netflix in the other room

[@amal3227]

I love the sound design and visuals on this

[@crackedwindowproductions]

Anyone here after watching the Netflix trailer?
