- In the first of a new three part series, we go behind the scenes of Super Kamiokande, the world’s largest neutrino detector.
For more than half a century, Japan has been at the forefront of 'big physics', asking fundamental questions about the laws which govern the workings of the universe. Questions of this magnitude require cutting edge technology on a truly massive scale. Over three episodes, Nature reporter Davide Castelvecchi travels across to Japan to get a rare look inside three of its flagship experiments.

3:33 "They are so sensitive they could spot a candle on the surface of the Moon." is such a beautifully poetic statement about a master crafted instrument of discovery.
You sound unhinged. It is NOT a poetic statement. It is what this thing is literally capable of.
@@alainportant6412 Lashing out at people for no reason is unhinged.
7:13 Hyper Kamiokande
@Grand unified celery "We aim to discover proton decay. That's not yet discovered in Super-K."
@@drurysherry If they can confirm the existence of proton decay that would be not just one of but THE most bitter sweet discovery in history. It might mean we will learn the Universe's expiration date.
@@orion3253 Sounds like one big elitist jerkov with no application whatsoever.
I hope taxpayers aren't funding these big holes in the ground !

People claiming to not be able to understand some of the scientist speaking. TURN ON CAPTIONS!
I had no issue understanding him
Just the people claiming they can't understand need to turn on captions ur good. 👍@@Gangstabean420
Inside looks like a film set of a sci-fi movie! :O
So awesome
I was reading about this
Came to see how it looks like
Me encanto este reportaje
Finally seeing Super-Kamiokande in TH-cam.
Japan ❤
Thank you, Japan!
Wow! Thanks for sharing this with the world.
Wow it's like a giant pool with 100's of eyeballs covering the walls. watching.
How about to arrange the pattern in a fractal pattern ?
This is gonna be my favorite!!!
Part of the movie Eagle Eye was filmed in this room
Explained so simply by Shiozawa
It's bigger on the inside!
thank you so much
Ghost Particle? 1:25 TO 1:47
thank you for video
do they vacume seal it?
2:27 its background, not noise
That's a lot of water weight, correct me if I'm wrong but 50,000 tons of pure water would weigh 100 million pounds?
Subtitles in english of the spoken text would faciliate understanding.
Turn on captions
@@michaelharrington75 Thanks - didn't realize it ..
SUPER GENIAL. SORPRENDENTE TRABAJO MADE IN JAPAN. EXITOS Y ADELANTE CON TAN BUENA INVESTIGACIÓN. Creo que poco a poco descubrimos que vivimos dentro de una materia-mente que tiene vida propia. 100 puntos para Japón.
Wow before I watched this video then you show me a picture of the inside of that Super-Kamiokande, I wouldn't believe you
This should be at least 30 min long.
Interesting and appreciated, but it would have been really nice to have had some subtitles, so we could properly understand the Japanese scientist being interviewed, and know the job title of the people being interviewed.
Any chance of this in your next two videos?
There are subtitles. Go to menu on the video and turn British English on.
When is Kamiokande 64 coming out?
next should be kamiokande cube? lol
And im still here with the kamiokande entertainment system
Kamiokande VR plz
This is NERV hq?

@@Daniel-gj2cd They still haven’t showed central dogma and Lilith
@@namesomega3694 I'd rather not see a real life version of Lilith tbh
her hair is also weird. outside the Standard Model.
Is that David Byrne playing banjo in the background?
Is it just me or does he sound *exactly* like Károly Zsolnai-Fehér from Two Minute Papers?
Neutrinos
Breakfast of champions
Im literally hearing:
🔊🎼🎶"In the Hall of the Mountain King 👑 🏔️"
If neutrinos don’t interact with the EM force how do they produce light? Or is that just an analogy of what’s happening?
Small probability to interact..As they have very little tiny masses
They emit a very faint shockwave or radiation which the photomultiplier picks up, the purpose of the water is to slow down the neutrino as it passes through and the purpose of the location inside the mountain is to ensure that there is total darkness,it is called ghost particle aside from being difficult to trace it can only be observed at night.
Antinutrino is same as Anti matter ???
Antimatter is just matter with same properties except charge, for example positron, is just an electron but positive.
In the case of neutrinos, it's kinda difficult, because they don't have charge, so some say, antineutrinos are the same as neutrinos, i don't know how the difference them tho.
In 2001 one of the huge $3000 PMTs imploded under the pressure of the water column, generating a shock wave and setting off a chain reaction of implosions of adjacent PMTs that ended up destroying over 6,000 of the tubes in a massive cascade. oopsies
A cascade failure like that seems almost like a design flaw
In other words, you appreciate their recovery ability.

Am I the only one who thinks these videos should be longer?
what is this music in the background? couldn't you have just accompanied the whole thing with music without it sounding like super mario?
If neutrinos have some mass, how can they travel at the speed of light? Un peu slower, non?
Un neutrino ne pèse pas plus de 10^-37 kg donc il est 1 000 000 de fois plus léger qu’un électron, je crois que c’est l’explication
most likely a teeeeny tiny bit slower..which begs the question...what variance in speed do neutrinos have
Dang ol super mariocarte man
I can't stop hearing "The king under the mountain" in my head
Can we put regular music RATHER THAN stereotypical music. I mean, if this were filmed in the US you wouldn’t put cowboy music, would you?
to be honest, I quite like the music :)
What's wrong with it? It's good unlike cow boy music....
Relax sjw
As usual, your ignorance blocks all possibility of actually learning something
Am i the you one who would feel beyond uncomfortable inside there
1:21 I totally thought he was speaking Japanese here and wondered why there were no subtitles.
lol
It's only 8 minutes long??!! Come on.
Anyone what is the purpose
No doubt no good for humanity
The purpose was to detect and gather information about the activities of neutrinos
@@junkmail6475 for what gain
You can track nuclear reactors with this technology.
It's over 9000 of oragnge balls!!
Would it not be better to somehow observe how neutrinos affect living matter...like our cell walls? Where do kids get their energy? You hear this all the time...maybe in passing through our cell walls they make the tiniest of vibration...like hitting a drum skin...the mitochondrial dna uses this to distribute energy to our body...or the light body...kids cell walls are bouncier that old people so transmit more useable vibration
Nature is supremely unwasteful...
Further...answer this how do we know 100% for sure that the search for new particles by smashing light into itself...how do we know that is not creating the super small sub atomic particles rather than them being pre existent withing what you have now broken
Do they have an issue with algae growing in the tank?
John Murray its like highly purified water, basically just plain old H_2O
Does algae grow in caves? Why would it grow here
make that machine small , that we can hold. empty the tunnel. sent 1 person with it inside.
The japanese sounds like my friends but better
watch this tripping... thank me later ;)
I hope they have emergency crowbars there.
Mines of Moria if Thrain had Japanese ancestry
those who've seen Don't Look Up is it just me or the 2 foreigner scientists looks like Dicaprio and Lawrence ? (don't be mean i know some of u pendejos thinking. don't.)
This is jus tesla3
Building it on top of a earthquake fault, though?
Is that Jet Li's voice ?
Kelihatan ngeri
All this just to find neutrinos.....Well, everyone needs a hobby.
And what have you done?
English plzz
I want to understand
Thats why Samsung better than iPhone jajaja 🤣
pretty alt science gf
The f*ck is this music ?
WHY in the F are they wearing masks when in the tank? So much contamination is being exhaled into the tank it's basically FUBAR
you shouldn't speak english regarding such topics if you are not completely fluent in it. some things being said make no sense, and would be confusing to a native speaker.
He's English is very well spoken
@@wormwood6424 this guy is acting out like a woman
Great Video, thanks for sharing. Would be nice if you respect the japanese Culture next time and shave your beard before going into a hypersensitive Facility where a single hair can mess things up. Arigato gosaimashita ♥
imagine a neutrino-fission experiment and they create a supernovae explosion lol some things were meant to be left alone
I'm guessing this will have no good outcomes for humanity
That is an awfully pessimistic view to take.
@@junkmail6475 unfortunately true tho
all the big machine, other thing, is still big compromise for the environment. everything is creating energy.
How much did Japan pay to sponsor all these videos? 😂
Jayanta Mondal I wonder how small your brain is to think Japan need to pay to advertise these kind of video....Japan technology is well-known as one of the most advanced and futuristic, even for the United States...What do you think Japan get from sponsoring these videos ?
Raymond Pham You really have a minuscule brain if you can’t comprehend the huge amount of publicity that Japan stands to gain out of this. Publicity brings public confidence and more investments and funds for that specific country. If you still can’t understand and turn a blind eye to it, you are surely living under the rock.
@@jayantamondal719 honestly, the funds and grants a public-announced project received mostly not about these kinds of topics like in this video...For example, my biology professor at UCI received 10 millions dollar funds from U.S Army and much more from other department of U.S government annually...His research is about using stem cells to boost the reproductivity other cells...I was like wtf when I know about his research and amount of funds he get every year. but no one really know about his research until I work for him as an undergrad student...Hope you get what Im saying here....These kinds of video is more about educating and informing the audience more than attracting money from investors
@@raymondpham297 not his but your brain is miniscule
@@vishveshtadsare3160 Talk of Nature getting paid to visit a place, it's the most reputed scientific Journal in the English speaking world for sciences and just yesterday they wrote Google to back off from publishing low quality papers.
İnitial music is so bad.
It's only 8 minutes long??!! Come on.
