Why the Three-Body Problem is Unsolvable*

What is the THREE-BODY PROBLEM? What does it have to do with the award-winning book of the same name? And how can it help us understand problems that are practically… unsolvable? Noted Space Zaddy Kyle Hill explains.

“Chaos does not mean randomness.” A sentiment shared by respected scientists and exasperated dungeon masters around the world.

[vsznry]

I just realized.. this was the whole point of Heath's Joker:

All these years I was a bit confused because the Joker describes himself as an Agent of chaos & a dog that chases a car without understanding what its doing.
But then he seems to have planned every little detail…

Thus, that's the whole joke,
the Joker is unpredictable, but not random.

Fun fact: Tolkien included elements of this theory in the Lord of the Rings. It was represented by the question: where are the Entwives? aka: the tree body problem.

Jeff seems like someone who treats everyone like long missed old friend but doesn't actually remember anyone in particular. 😅

[omgchomp]

"he's a friend from work" got me lmao

@7:16 "back when this virgin was creating the cover for Dark Side of the Moon" - ABSOLUTELY EPIC.

"What is Chaos?"
CHAOS IS THE ONLY TRUE ANSWER! - Most sane chaos cultist

"to recap, no cap ... fam" - Goldblum levels of cadence and delivery 👌

Fact (of the fun variety): chaotic systems with very small predictability horizons are used to generate "random" numbers in computers because digital machines are very bad at not following precise, predetermined steps. That is why pseudorandom algorithms are still repeatable and you can play on the same Minecraft world more than once if you copy down the seed value (initial condition).

Edit: it seems a lot of people are confused by my phrasing. I'm not saying chaotic computer algorithms are the _only_ way to generate pseudorandom numbers in computation, I'm saying they are used for that purpose. The video is about chaos, not generating random numbers, so I'm making the connection lol

"back when this virgin was creating the cover for dark side of the moon"
man, thats a lot of chaos in that joke

[ntm]

The layers in that "he's a friend from work" joke. Amazing.
(There's the obvious Thor says that line and kyle is discount Thor layer. But in addition, Jeff Goldblum appears in the movie that line comes from [Thor: Ragnarok]. So during the filming, Jeff and -Kyle- Chris Hemsworth were in fact coworkers.)

[usernametaken]

Awesome stuff. I never even considered why we couldn't predict weather further than a week's time, this is the kind of stuff you never stop to think about, and we usually take for granted.

[doggedout]

"Goldblum!" I often yell, at the sky, while shaking my fist.
For no particular reason.

The best thing is that they got the dialogue right AND the attitude right: he's right on the line between smug and infinitely humbled.

My brother in law asked me if I had been watching the Three Body Problem. I told him I had not, but I was familiar with the concept in physics and proceeded to explain it to him and its history in the understanding of chaos. He said I should really watch the show. I haven't yet, but I probably will.

As I understand it, its only unpredictable because you don't have precise or complete enough starting conditions to remain accurate for as long of a time scale as you're interested in. The longer the time scale you want to be accurate over the more precise your starting conditions need to be.

It could be just because you didn"t measure precisely enough to be accurate over the time horizon you want, Heisenberg's uncertainty principle means there is a limit to how precise your starting conditions can be, and random quantum phenomenon adds randomness to your system.

So even if you had a system with no introduction of randomness due to quantum phenomenon (which is impossible) and you exactly measured the velocity OR position of each particle in the system to an "infinite number of decimal places". Heisenberg's uncertainty principle means there will always be a non-zero level of imprecision in your starting conditions. So the time horizon of accuracy of any model is inherently finite.

An entire video dedicated to chaos ? Mmmh...

The coastline of Britain will also constantly change, since water is constantly eroding it. Not to mention the sea levels are constantly changing. They could be going up as the polar caps melt and add water to the sea or recede if we start getting another ice age from the water freezing up.

Kyle - This might come across weird, but I love you, man. Your videos are chock full of awesome info, but it's your sense of humor that make them. Honestly, never laugh as hard when I'm learning as when I'm watching one of your vids.
