When you break 3 rules of natural law and they give you the name 'weak'
"You dare oppose me, mortal?"
Seems right.
😂😂😂
🤣Too underrated man...
Hank *really* conveys the utter bafflement & distress the weak force introduces to physics.
My dude, when he was talking about some of this stuff. I was like, how did he just say that like it's Tuesday? My head hurts.
@@wesleymercer4536 This video is kinda garbage don't worry. Seems like they parroted some sensationalist news article from 2010 or something, instead of researching it and explaining it appropriately.
@@KucheKlizma all of it is true, it isn't sensationalism.
The weak force can even break conservation of energy, but only briefly before the energy gained has to be destroyed again, making the overall interaction net-neutral. This is also why the weak force has such a short range - the w- bosons have to be destroyed quickly in order to destroy the energy formed by their generation, during which time they can only travel so far.
This can happen because according to quantum mechanics, as long as the change in energy multiplied by the time the change occurs for is less than Planck's constant, energy can indeed be created and destroyed.
Edit: must say I'm still confused on this last part. Everything I've found says *more than* Planck's constant, which seems contradictory to the idea of requiring a short timescale, in fact requiring at least a minimum amount of time, with seemingly no upper limit. Not sure what's going on here.
@@alansmithee419 Do you need any help?
It's adorabe and hilarious. I FINALLY GET IT
I'm starting to think physicists call it weak purely as an insult.
I know this is a joke, before I get whooshed, but I thought you may be interested to know that the reason it has that name is simply because it's weaker than the strong force. It is in actuality much stronger than gravity, but these two are the nuclear forces, of which it is the weakest.
@@alansmithee419 its called the weak force because of the distance it effects and not so much the strength of its force.
@@mikoi7472 I did some searching.
I found one source that agrees with your explanation and one that agrees with mine.
So it seems no one really knows.
@Jushiro Ukitake I already knew the weak force was the weakest in terms of the 3 already derived from electromagnetism. (Until a theory of everything links gravity as well, if it ever does.)
I was simply talking of the naming scheme of the forces. At the quantum level like that we don't necessarily talk about strength in the same way. For instance, gravity on the small scale is the weakest, meaning it effects the least, but on the grand scale it becomes the strongest.
@@mikoi7472 Wrong. Strong force is much more powerful than Gravitational Force. Only blackholes have a stronger force than thy Strong force.
Yep. Yep. I know some of these words.
Me too, SCIENCE!
lol funny comment!! That said, he explains stuff quite well, at a level that anyone with a high school physics course under their belt, can understand especially if one looks up a few of the trickier words such as "charge parity".
I just wish he'd stop taking speed and slow down enough for me to contemplate his stuff.
@tundrazwolf he doesnt mean understand it completely. he means understand the weak forces role and answer the video question. obviously youre not gonna learn every detail of particle physics from this one video.
@tundrazwolf it depends how much you want people to understand. i understand that weak force is breaking a bunch of rules. how its doing this maybe not but thats not the point of the video. any highschool kid can now answer the question to the video.
Best closing ever: "We hope you're okay after that." 😁
Yeah, I am actually pretty disturbed... I didn't know this before! :(
Maybe (I've suggested this before, but I'm just a regular guy, so no one cares) there's something wrong with one of our previous assumptions...
Like the Red Shift - maybe there's a fundamental principle of the universe that we're ignoring, misleading us into changing our measurements??
great revelations in science are almost never an "Ah-HA! I've found it!" type of moment. They are almost always "Hmm.... that's not what i expected...."
Sometimes they're even "WTF just happened?"
"That's the third batch this week that's gone mouldy...wait, what's that?"
Or "huh? that's weird"
**THANK YOU. This is the first time I have seen anyone explain this interesting feature about the weak force.** Before this video, I didn't know a) the weak force violates time symmetry, or b) the weak force differentiates between matter and anti-matter.
I have watched tons of of popular science videos by well-known experts about particle physics, and consider myself a relatively well-educated layman. I've seriously watched hundreds and hundreds of hours. I actually recognize some of the terms, but this is the first time anyone has explained it so they made sense.
Check out Fermilab & PBS Space Time,
And prepare to be confused!
Pbs Space time is just there to mess with our mental health at this point 😂
Those two channels, plus David Butler are my absolute favorite science channels. I think they all probably mentioned what he's talking about here, but this is the first time it was explained so it made sense.
I'm in a similar boat, I can't believe I hadn't come across this already!
I like people in other boats like mine. let's be friends!
Maybe the "Weak Force" is just pissed off because we've called it "weak", so it's throwing a tantrum.
Also, on a less jokey sidenote, but equally ignorant, maybe there's no such thing as going backwards but only forward in opposite directions. I don't know why that popped into my head, but I had to get it out here.
Ricardo Petinga to go foreard in opposite directions implies that you've turned around in between. So that is a different concept to going backwards.
@@TheRABIDdude Got it. Hadn't though of it like that. Thanks!
Look up some thing called "Feynman Diagrams" where the three dimensions we live in are all on the x-axis and particle transformations are on the y- axis. Scientists studying these diagrams have proposed that these diagrams suggest backward time travel is possible, because the particle interactions going forward are identical to these processes going backward if you put negatives inn front of each particle. ( for negative particles, a negative times its own negative turns it into a positive particle.)
* Insert Infinite joke here. *
It's slander is what it is: The weak force is about 25 orders of magnitude stronger than gravity. It's only because gravity's force carrier has infinite range and (as far as we know) there's no negative mass particles, that gravity gets away with its weak sauce performance. When every atom in the planet pulls at you together, it finally gets noticeable.
1:00 "It's the Mongols of the forces." LOL I got that CrashCourse reference.
The mongols are like an easter egg throughout the entire content the greene brothers have put out haha
It made me very happy
Physics for historians
I'm out of the loop, what video/s did I miss?
I don’t understand but would like to know
Weak nuclear force appears
*confused screaming*
This writing is amazing! So many concepts were efficiently introduced! Thanks!
It must be terribly difficult to write so effectively. They’ve got the it down!
That’s the difference between good science and ‘good’ sociology: science benefits from being pithy; sociology conceals its emptiness under a grossly verbose and repetitive barrage of vacuous but vehement opinion.
wrr, say any nmw is ok
Hank Green is the best, I get a little sad when I click on a video and he's not hosting it.
"It may be the reason you exist!"
As opposed to all those totally unnecessary fundamental forces
Possible Episode Suggestion: How exactly do the diffrent types of Radiation ( Alpha ,beta , Gamma and Neutron) effect the DNA on a molecular Level? Keep it up with the more complicated Videos they do actully teach somethimng new instead of cewing old well known stufff again Thanks SciShow!
You probably mean "affect" rather than "effect", although that is conceivable, too, just less likely.

I'm not sure but won't the decay particles just interact with the nucleus of your atoms.
This changes the atoms properties and causes them to become unstable.
This will slowly spread throughout your body since they are unstable and decay again and again.
The answer is: 42
Ben Helmet I'm afriad that's not correct at all. That chain reaction is what happens in a nuclear bomb, not in anything else.
The weak force is also responsible for stars, because the proton-proton reaction relies on the (rare) conversion of a proton into a neutron in a proton-proton collision to create deuterium.
You will need an extra electron to create neutron in deuterium
So why it's called H H fusion or He h fusion instead of P P fusion ?!
Really nice to see you exploring more difficult topics and approaching them in a simple way ; would be nice to see you go into more complicated details with all types of videos.
"Weak, am I? I'll show them. I'll be a thorn in their side that they can never remove." (Diabolical laughter follows)
PBS Spacetime did a really good video on CPT symmetry!
Ah let's see. There's gravity, which refuses to be quantized like the other 3 forces. The weak force, which violates CPT symmetry, and the strong nuclear force, which we don't even fully understand or have a proper mathematical framework for. So electromagnetic is the only "normal" force. 😄
It violates cp symmetry, not cpt. Scientists hope it does not violate cpt symmetry.
+TheDeafCreeper Hmm didn't Veritasium do a video on that saying we'd discovered a particle that violates CPT?
@@feynstein1004 I don't believe so, I thought he said the same things said here. It's been awhile since I watched that video though.
Meh, the strong force is pretty well understood (if you make the usual assumptions that high energy is weird). We definitely have a mathematical framework for it (QCD).
And the weak force is somehow bound to the electromagnetic force, the electroweak force governed by the
W and Z vector bosons.
I've always wondered if there were particles smaller than quarks that act as the true fundamental fabric of all reality, ultimately governing the physics of all other particles and forces
We are limited by what is observable to us, which is governed by our rate of technological advance. Given our infancy in regards to technology, it would be naive of us to think that the current macro/micro scale objects are the true limits of what exists. I would say it is almost certain that there exists even larger/smaller objects/forces/whatever, including sub Planck.
q.v. Preons
Hank can make just about any topic interesting. He has just the right amount of humor in his talks, usually through expression not just words. Good job Hank, I'm guessing we will see you on TV one day.
It's honestly so exciting to me whenever I learn about things that scientists find "weird" and can't quite figure out yet because it really sparks my imagination to try to think up solutions. I'm sure that it inspires the experts in these fields even more! It's exciting to imagine all those minds out there trying to solve all of these riddles our universe is filled with.
"Use the Force Luke!"
[Luke taps into the powers of the Strong side]
"NOT THAT ONE!"
What did the Jedi Proton say to the Sith electron? ..."The force is strong with me!"
Why do you protect those who are weak? They only act to decay your little rebellion.
For 3 years i have been putting off subscribing cause i fell you never go in depth enough. you make things funny instead of giving more information......this episode did it. you got me today. Kudos.
For what it's worth, that was a good episode. More quantum mechanics, I'd say. Moar!
I also would have at least mentioned that the weak force and electromagnetic force have been combined into one "electroweak" force, making the odd nature of the weak force even stranger. Maybe skip anything else about the electroweak force depending on your audience, like the internal gauge symmetry of (SU(2)XU(1)) and what that means mathematically or that the unified (electroweak) theory starts with a set of four massless vector bosons and that because those bosons are massless, the theory becomes renormalizable, which allows us to eliminate certain infinities that would otherwise make it hard to understand.
But still, it's interesting that the electromagnetic force is "well behaved" when its cousin is the Mongols.
So, whenever you learn a new word, it helps to keep it stored if you can use it in a situation... 🤔 Situation to use "renormalizable"...
There's also theory that all the forces were once united as one "superforce" at or around the time of the Big Bang, so really all the forces might be just aspects or different expressions of the same thing, the same "superforce", not just only electromagnetism and weak force combining ;)
everything is light.
+John Doe: Just curious, to what do you refer? Clearly, everything is not "light" in a conventional sense. You might be referring to the holographic principle, although that isn't related to the "holograms" we make with lasers, but instead really says that the maximum amount of information that can be contained in a given region of space is proportional to the surface area of that region, rather than the volume of it. (And if you were to pack too much information into a given region, that region would collapse into a black hole, at which point any additional information added to the black hole--as matter or energy--would increase the size of surface area of the event horizon of the black hole to maintain the balance.)
I may be wildly misinterpreting what you mean, though, so thought I'd ask.
sorry, everything is electromagnetic radiation.
Weak force laughs at the face of physics
weak force watch physics and says: pfffffffffff rules...

I always thought gravity was the most hated because we can’t properly integrate it into the standard model
RapierNeedleCrime they are all hated in a way, if you really pay attention you realize science is all about constant hate on everything
Standard model is fine. quantizing it is a pain
I hate it because it always gets me down.
you really had to go there.......good one.
Just give the scientist a comfortable bad, then had them sleep on it. I guarante they will love "the gravity" after they woke up from their sleep 😎
This has been the most well explained video of what 'reality' is i've ever seen. The weak nuclear force is a paradox within our universe and you finally made it click for me.
*May the weak nuclear force be with you*
And also with you.
Always!
Damnit, Gudako. Go back to spinning the Gacha.
Aw thanks. May you not be cancelled out by antimatter, either
That’s not how the weak nuclear force works!
This is, by far, the BEST scishow episode I've ever seen!
Because all the other Nuclear weight lifters just need a decent spotter! Gotta make them GAINZ! (Sorry Muscle Hank)
Uh oh....muscle hank won't be happy Tom
Cinedojo haha I'm shaking in mah boots!
"we hope you're OK after that", Apart from the mild headache, yeah.
One of your best in ages IMHO. Love more in depth content.
Excellent episode!
"Hopr you're okay after that" - haha did not see that coming as a closure.:)
This is a very good video overall. I have a few (hopefully constructive) suggestions.
1: Please stop oversimplifying matter/antimatter interactions (5:20). It's becoming a sore spot among some of the other science educators, such as The Science Asylum and Fermilab, which will probably result in more "debunking the myth" videos. The result of matter/antimatter contact is far from "nothing".
2: IMO one of the coolest things about the weak force is that it isn't always weak. For some particle types, it's an extremely strong force.
3: I think it's also worth mentioning that at high temperatures, the weak force kinda "merges" with the electromagnetic force to become the electroweak force. So if the weak force is the unusual goth kid in your class, and electromagnetic is the popular kid that everybody knows, they eventually get married.
Weak + electromagnetic? I ship it.
With that analogy things get pretty wierd when at even hight temperatures/densities the also merge with strong force and gravity
You are missing the point. Whatever you are saying MAY be 'cool' to know but isn't relevant to this video.
This is my fav episode in months, thanks Hank.
so an aberration that makes the weak force a Mongol is the reason the universe exists at all.
i may or may not be having an existential crisis after learning this.
My kid also violates T symmetry, if I buy a big lego creation, he can turn it back into bricks much MUCH faster than I can turn the bricks into said creation.
This episode is amazing! Thank you SciShow! :-)
Excellent piece. And ,I always get really good feelings listening to your intro beat.
A few problems with this video:
1) Not all radioactive decays involve the weak force. In particular, α-decays - where an atom spits out a helium nucleus - really don't have anything to do with the weak force.
2) Weak interactions come in two types. What this video describes are "charged current" interactions, mediated by the W, which change the identity of particles. But, there are also "neutral current" interactions, mediated by the Z, which do not.
3) It's really just wrong to say that the spin states the weak force discriminates between are "clockwise" and "counterclockwise." That should be easily made clear by asking "clockwise relative to what?" The only meaningful answer to this is "relative to the particle's direction of motion." (This defines what are called "helical states".) The problem is that someone moving faster than the particle would see it as having the opposite direction of motion and, thus, the opposite spin sense. But, the motion of an observer can't change whether or not the particle undergoes a weak interaction.
What the weak force actually discriminates between are what are called "chiral states". Unfortunately, no one seems to have a good intuitive way of explaining exactly what these states are. (Shockingly, telling people that they correspond to the two different spinor representations of the Poincaré group doesn't usually help much.) So, while it's understandable that explaining chiral states would be outside the purview of this video, and while there _is_ a connection between chirality and helicity (namely that the chiral and helical states approach being the same as speed approaches the speed of light), it's really just not right to substitute in the helical states instead.
While you are correct, this would never work as a video for wide audience. Those minor simplifications are fine price to pay for explaining HEP to people.
(So that we keep having funds for research, lol)
The W and Z are also a vector bosons for the electroweak force.
@@gerhardshtopany5360 Agreed on the third point. But the in the first two he is correct, they could and should have mentioned them.
@@windsaw151 No. The concept they were trying to get across is differentiation and the fact that of the four fundamental forces only the weak force differentiates. That was clear. The basis for the differentiation may, from YOUR point of view, be oversimplified, but for /me/, with nothing more than grade 10 physics of 30 years ago and a lifelong appreciation of science, muddying up the explanation by including multiple extraneous definitions that do not contribute appreciably to the concept of differentiation by the forces, is both unnecessary and counterproductive.
A general rule of thumb in ANY explanation is "more words = more confusion." Unless all the words used are familiar and comfortable, in which case "more words = less attention".
That's why you didn't learn about any of these in grade 10 physics either.
Jesus you are seriously obnoxious about this. You have to understand that spin is a very difficult concept to grasp and not everyone here has a degree in physics to understand that concept. Unless you can explain this concept to someone who barely went through 10th grade physics without frying his brain you're wrong. Start being humble and think about what others think like, and stop acting like an obnoxious intellectual who needs to nitpick every single stuff and expect everyone to be on the same level as you.
Best SciShow episode in ages! Thanx. love

Well written episode unlike some of the sci show space or seeker anything episodes. Man. That was refreshing. Thank you
Can you do an episode on the Unreasonable Effectiveness of Hydrodynamics?
I really liked this video. It was nice to see SciShow dive a little deeper into some of these more intense topics!
Ok. Let me run something past you (not going to do the Patreon thing right now): whenever I see stuff about symmetry-breaking I always have to wonder if that discrepancy is being compensated for somewhere else. Your tutorial thus reminds me of another question that occurred to me a couple weeks ago: Is Uncertainty conserved?
To whit: quantum effects make Heisenberg's coupled quantities unknowable beyond a certain precision...and YET we have Quantum Entanglement, where measuring spin on one thing ABSOLUTELY determines the spin on an entangled partner...even across the Galaxy...
...so does it not seem that the "lost" certainty is appearing somewhere else? Is (UN)certainty *Conserved* in the final description? IOW's, is the "missing" symmetry actually just _displaced_? Perhaps even accounting for the time bias?
I reccomend you to sit down
Drink a cup of water
And breathe

Hank's antiaging secret: weak force.
You can tell the age of a video by how long his hair is. It keeps getting shorter. There was also a period where "Evil Hank" was hosting.
Wow! Good job Hank. I geeked all over this video.
Where's Muscle Hank when we need him?
He died
That was amazing! I’ve been looking for more videos on symmetries after watching PBS Spacetime to get a better grasp on it. I would love to see more quantum theory and astrophysics videos!
One video I would really enjoy: What the heck are the other leptons? (i.e., tau/muons, and their neutrinos)
I don't really know myself so yeah, that would be interesting. From what I've read/seen so far, it seems like the electron "wants" to decay into a gamma ray but can't because it possesses charge (and charge cannot exist in isolation; it has to be bound to something) but when that charge is eliminated when it meets a positron, both particles are free to decay into gamma rays...which they do.
Muons (and taus) are heavier versions of electrons and since decaying into less massive electrons wouldn't violate conservation of charge, they do decay...and quickly. Though I have no idea why muons and taus are the masses they are or what causes charge to come into existence in the first place but charge does seem to be that pesky thing keeping us all here in existence.
The RUclips channel “kurzgesagt or in a nutshell “ created a RUclips video called “what is something” that covers some of this stuff.
That is a great video! Until now I've never understood what the weak force is, what it does, or what purpose it serves. Thanks Hank. Thanks Sci Show team.
Get your bets in on what Muscle Hank will say😂
Sebastian Elytron better not disappoint with a “weak” response.
Or an elaborate hank troll
"The weak nuclear force is for the weak." Is my guess ^_^
I haven't seen muscle Hank in months. Is he still around?
@@TheFlipside he died of Parkinsons disease
Okay now this is weird. there's 3 people in this comment chain with the first name "Sebastian." Myself included. I never thought that would happen
That was an AMAZING explanation bro!
Hmm, so let's create a hypothetical universe that is all antimatter. Given that the weak force converts -B0 to B0 faster than B0 to -B0, wouldn't a population inversion occur anyway where there would eventually always be more B0 than -B0?
Nice :D
That's only if the reactions happen more or less as frequently as one another. If -B0 to B0 conversions happen less frequently for some reason it would balance the scales. I don't know if that's true for our universe. Just throwing that out there.
Yeah, that makes sense. I was assuming about a 50/50.
In an antimatter universe it's not entirely sure what would differ. B0 mesons are rare and exotic things that rapidly decay. A preference would be noted, as it is in our universe. But we don't know if other, more common but smaller changes might have bigger effects. For example some anti-isotopes might decay at different rates to their matter counterparts, changing the balance of elements. An antiverse might be much like our own, totally different or impossible to even create.
@@Voidsworn Could you explain the B0 joke to my friend?
So interesting!! Thank you SciShow!!!
It's not the length of the vector that counts...
It's how you apply the force.
Interesting video SciShow! I’m would like to learn more about how the universe is both expanding and a hologram at the same time and how that fits in with the world as we know it including the laws of physics that govern everything.
Not as weak as me *eyyy*
kremit the frog not as weak as your sex life
That's mean innit
Hi, Hank,
you asked for it, so here's a case.
It's about gravity - mass attraction - and inertia.
We can hide the effect of gravity with a variety of tricks. For example in
a falling elevator. And with some other tricks as well.
But whatever we try and do and do, we cannot hide the effect
of inertia as a mass is set in motion from rest.

A fascinating explanation, of this oddball force, which I never knew about. Interesting stuff.
what is going with spin? Everyone says 'this is spin but not its really spinning that's too complicated to explain. can you please at least try to explain it?
@Kay this was very helpful thank you, I have researched the subject further and your explanation seems to line up with what others say, except how you say it makes it much easier to understand.
I love videos like this, it's been to long in my opinion, I have wanted to know about week force for a while.

Do a video on fetal microchimerism! It's so wild.
Does the fetus develop animap parts?
haha no not exactly! Basically in mammals, fetuses develop with some of their mother's cells and mothers develop with some of their fetus's cells and this seems to contribute to autoimmunity later in life but it also helps the mother's immune system to tolerate the fetus. So everyone has cells in their body that aren't genetically theirs.
@@4loscomments I think they covered that partially in a previous 10 vid. Something about the top 10 ways being pregnant is like hosting an alien invader in your body...or something. You make it sound more as if it's deserving of it own vid, though.
It definitely is! It's so fascinating. Honestly everything with the immune system is fascinating but I think this is especially cool.
Well they gotta do a vid on chimerism in general, first.
Thanks for the good explanation of the symmetries!

Weak nuclear force: ''hey look at me, i'm a special snowflake"
It's basically the force that wants to paint its walls black, listen to Linkin Park all day and yell stuff like "IT'S NOT A _PHASE_, DAD!"
...I have no idea who a force's "dad" would be, but you get the idea. :P
When you shoot a beam of subatomic particles in between specially shaped magnets some curve one way some curve the other way. Nobody knows what property is causing this so we label it spin because spin is binary.
Particle spin is treated like it is some elite concept that can't be understood by regular people.
When you're explaining the weak force, there is no need to stray off topic and accurately explain spin. It's good enough to let people see it as a spinning particle. They're not treating us like children or hiding something. They're simply focusing on their primary topic.
The particles curve because of charge not spin.
Spin is better described as polarity of a wave.
So everyone is a mistake😂💀
No, everyone is the weak force trolling the universe.
Yay, it's not just me.
Not really, Determinism shows everyone MUST exist. That's just the way our Universe is goin'.
