Agreed Fred should definitely do a video on DUNE and LIGO/VIRGO. A bit unrelated but within Physics is also ITER - the most complicated machine humankind has built. A lot of construction quirks within all those experiments!

Great video! Physicist here. You got one thing slightly wrong: All particles are either of type boson (spin is a whole number & that is usually a force transmitting particles) or fermion (spin ist NOT a whole number & that is usually some kind of matter). Neutrinos are of type fermion (some kind of matter) and quite heavy for their size, but they hardly react with any force we know off. On the particle level, measuring something is the same as interacting with it. And since neutrinos do not really interact with other particles, it is absurdly hard to measure them - or even show they exist. That is also why neutrinos are good possible candidates for what constitutes dark matter. And since dark matter is a huge topic (gaping whole in current cosmology), neutrinos are especially interesting. Thanks for shining light on this topic. The construction side itself is already nuts.

Particle physics has gotten to the point where much of the experimentation is of massive scale and massive expense. And a substantial amount of the particle theory is so far out there that it can't be tested (eg string theory) and thus has attracted significant self criticism by some particle physicists pointing out that it's dubious science (science needs to be testable, or, as they say, falsifiable, to be meaningful, and a lot of bleeding edge particle theory cannot be, so is it physics or is it philosophy?) There is a lot of physics that can be done for $600mm that this neutrino experiment costs. For instance, high temperature superconductor research is much less costly and potentially far more impactful. That the world wide web is accounted for as a practical spinoff of particle physics is telling. It's got nothing to do with physics per se. There's nothing wrong with physics for the sake of physics, but again, when one particle experiment costs $600mm, there is a lot of other physics that could be done with these dollars (yen, euros, etc).

Nice little physics lesson to start us off. One note is that neutrinos do interact with other matter (or else how would we detect them) it’s just extremely rare. That’s why we need a giant vat of water under a mountain, to act as a filter, reducing all the noise of other particle interactions which would far exceed any interactions by neutrinos. As you mention later, it is the interaction with an electron that the observatory measures. Anyways, love the channel!

As a Particle Physicist, please next time get some consulting from an actual scientist it's painful to listen to at times... First our known matter is made out of Fermions and Bosons, Quarks, smallest building blocks of Protons and Neutrons in the nucleus are Fermions as well as electrons and neutrinos, while all interactions vectors are called Bosons. Neutrinos are amongst the lightest and least interactive particles, talking about size is a smidge misleading, and I would refrain of using regular sizes to compare particles. Note that they do interact, which you stated later in your video, but the initial claim of not interacting is wrong, they do but with very low probability, which explains why the target needs to be so big. In the case of CERN we never detect directly neutrinos, as you mentioned their probability of interaction is quite small, so even if we have a repetition rate that is quite high (40MHz collision rate, the actual data taking is quite smaller but whatever) we detect all the particles that do interact and then look at the missing momentum in the event, which indicates that something left the detector without interacting. You can detect neutrino from accelerator but in this case the intensity of the neutrino beam is high because they are specifically generated to be shot in a certain direction. It is noted that the Cherenkov radiation is coming from the electron being kicked around moving faster than the speed of light in the medium and not the neutrino itself. Otherwise interesting to see a video about HyperK and the engineering behind it. If you are interested you could look into the civil engineering of the LHC or for that matter the FCC, it's quite interesting.

FYI, while smaller, there was been a neutrino detector like this in Sudbury, Ontario, Canada. The Sudbury Neutrino Observatory (SNO) was a neutrino observatory located 2100 m underground. The detector was turned on in May 1999, and was turned off on 28 November 2006. The SNO collaboration was active for several years after that analyzing the data taken. It used a 6-meter-radius (20 ft) sphere with 1000 tons (1M kg) heavy water, and was suspended in a vessel which was filled with normal water to provide both buoyancy for the vessel and radiation shielding. It had about 9,600 detectors.

With surprise he discovered a way to unify all the particle physics in terms of a beautiful mathematical framework. The model he discovered called SU(5) Grand Unified Theory and if it is correct proton should undergo decay. One of the purpose of this giant water tank is to detect that decay. Now its time to wait to see what it can discover.

It's so hard to wrap my head around neutrinos. I think of it this way: a neutrino is so, so tiny, that even atoms are spaced so far apart - like stars are to us - that they can pass through without interfering with them. I've no idea if that's the correct way of looking at it though :D

The Super-Kamiokande is so beautiful looking despite being just a big test tank.

Make sure when you create the tunnel you make it to where people can walk on it on both sides to get from vehicle/train. Also make it big enough to let rescue crews be able to move freely and turn around in cave with their vehicles to avoid having to shut cave down due to dangerous hazards. Also make sure you have a two way strip inside because of traffic flow being blocked on one side could cause horrible delays and angry people. Also put a slow speed limit so if someone wrecks it doesn’t do much damage to the people in the cave, the vehicle driven, and the cave itself. Just a little tip or too you probably are aware of.

This is amazing

Quick correction : the Icecube neutrino detector at the south pole is larger than this.

So why do we want to detect nutrinos? It's not like they effect much stuff since they rarely hit anything

Timestamped Highlights 00:28 🌍 The Hyper Kamiokande is a massive structure being built in Japan, costing over half a billion dollars, and is the largest neutrino observatory in the world. 01:43 🏔 The structure is hidden deep in Mount Nugo, which provides excellent insulation from background radiation, making it ideal for spotting neutrinos. 04:24 🚧 The construction process involves drilling and blasting through rock to create a cavern, which will eventually be filled with 260 million liters of water. 06:46 🔬 The observatory will detect neutrinos by observing the weak glow called cherenkov radiation produced when neutrinos collide with electrons in the water-filled cavern. 08:55 🌐 Advancements in particle physics have led to various applications, including medical scans, tumor diagnosis, and treatments for diseases, as well as improved weather forecasting and information sharing systems. 09:57 🎙 Learn more about the Hyper Kamiokande and other construction topics on the world's best construction podcast, available on various platforms.

i definitely thought of this first i should’ve done it

The University of Utah constructed a neutrino detector in a silver mine by Park City in the 1960s and to access it you have to ride an old time mining train wearing a hardhat and coveralls which I got to do as an undergrad.

🙏🙏 Thanks for the information

The 6:30 claim that it needs to withstand the massive pressure from all the water, it doesn’t work like that. It only needs to work against 70 meter water column so that’s roughly 7 bar

Hey I worked on development for part of this upcoming experiement!
