One thing my wandering mind came up with is using strong, precise neutrino beams as communication encoders/carriers. They would be perfect because they can go trough matter without interacting as ghostly as they are, yet hard to utilise untill we understand them better. But imagine if used for the something like the internet it could mean we can beam data trough the earth to the desired receiver instead of having to rely on our gigantic cable network that goes around the surface, cutting time and making the whole thing operate faster. Also creates options for a more direct peer-to-peer approach for communication. Other things that pop to mind are maybe they can be used for imaging tools for new purposes, like X-ray has. We just need to know them with more precision and how they do interact with other physics. Cool little things, they are! Edit: This starts to sound a lot like sub-space communication from Star Trek hehehe

Someone with more knowledge can probably come with some specific answers as to how this can help, but it's often the case that research like this leads to technologies that were entirely unintended. If scientists didn't play around with electricity in the 1800s with no real clue of its applications, what would the world look like today? And research into quantum phenomena directly leads to things like better semiconductors and thus modern technology.

The applications are always largely the same with high energy physics. There's usually a few go-to ones: Sometimes learning the rules of our universe don't have obvious applications right now, but will down the line. An example is Einstein coming up with special and general relativity (both seemingly having no use for the layman in the 1930s), and both of those were incredibly important 50 years later when the US needed to perfectly sync 26 satellites in motion to create a Global Position System (GPS, which everybody uses near daily). Another benefit of high energy physics research is the stuff that's invented in the journey. Such as the world wide web (made to share documents at CERN), or better concrete or tunnel-bores or air-motion systems for underground colliders. Which then help mining and city foundation-laying operations worldwide. A third benefit is the actual direct benefits of the discovery, whatever it may be. Sometimes there's an immediate use (such as with electric lightbulbs or xray scans), and sometimes it's a delayed use (such as burning information into a DVD using lasers, or some future radiation proofing of shuttles for trips to Mars. The fourth, more philosophical benefit is that it yields something we can be proud of as humans. A military veteran or congressman might wonder how high energy research might aid in the military defense of the United States. A better thing to wonder is what in the United States is worth defending if not our arts and scientific achievements.

I love the new DUNE logo.

I think of FermiLab as CERNino. Or the smaller non-hadron collider. But I do hope they can learn a lot more about neutrino's.

My first thought was; who is going round sterilising all of these poor neutrinos and what have they ever done to us? Second thought was; what a bad joke that was but at least I got to see another fancinating video by Dr. Lincon and what fermilab are planning. I look forward to see what is learned. Possibly in a later vid? I could listed to Dr. Lincon for hours and thanks to this channel I have :)

Best wishes to Fermilab and to you, Dr. Don. I've heard about the troubles there and I'd hate to see the best accelerator program in the US go away.

Physics is everything! :D

Can you make a video explaining the theoretical rationale for the existence of sterile neutrinos?

The spice must flow

Did I understand correctly, or am I totally wrong: You measure a number of electrons and muons in each of the two detectors. Then you compare the proportion of muons / electrons to the total of detected particles (or the proportion between the two kind of particles), for each of the two detectors. Then having obtained the composition of the "particle cocktail", you can determine where you are in the oscillation, for a given distance. Or is it a bit more complicated than that?

Neutrinos are really interesting

Please build a detector or 2 for C.N.B. (cosmic neutrino background) to start mapping it.

Whoa! Doesn't another type of Neutrino muck up the nice symmetric grid in the Standard Model?

@juliavixen176

That "symmetric grid" illustration that everyone puts in pop-sci videos is crap. It's really misleading and leaves out a lot of information. There are other illustrations that are better. If the chart included chirality, then the sterile neutrino would fit into an obvious gap. (Anyway, that chart doesn't show anti-particles, or color charge... there are several different gluons, for example. Above the electroweak unification energy the W±, Z⁰, and photon don't exist, etc. etc.)

2:30 ... they might be able to change their identity in a process of subatomic switch loop called neutrino oscillation. 4:56 a paper

The beam in the video appears to curve around. How do you steer neutrinos? I thought that due to their low interaction properties they would have to travel from their creation and through both detectors in a straight line

2:40 consistent with, never proved.

Good news in Good new year 2024. Same for all members of your team who are making huge things for negligible masses since 1970. As my quest these neutrino is propose to take care of missing energy, then how various oscillation states or flavour is right for same energy lose. You are looking for another one could be a whole generation Feel lucky

The protons (red lights) are what are being accelerated and directed at the beam on the far right producing the neutrinos. (green light)

Have provisions been made (from a design standpoint) to remove the first detector from the stream to see if the percentages of the different particles change in the second detector.

can graviton have oscillation ? can it turn someting else ? i hope you kind something above Standard Model

can't measuring the same beam twice affect the results? Are not the beam of neutrinos affected in a way, that may change the outcome of the second detection?

Hi there, did you know about neutrino4 experiment conducted by Anatolii Serebov.......if I understand they detected right handed neutrino.....

Getting down to business.

3 cheers for a dune reference.

Cool as always ...BUT - Might be better without a "switcheroo" - totally crashed my phocus on TJE subject...had to check first what the swicheroo means and rewatch the video again

Question about black holes. I've learned from you and several other physicist explainers on KZread that an outside observer watching an object fall into a black hole sees it slow down slower and slower approaching the Event Horizon, but never actually fall past the EH. The object falls past the EH normally to itself, but watches all of time pass outside the EH. So how can a black hole grow, from an external perspective, if nothing can ever actually fall into it? And how can an object watch all time pass by as it crosses the EH, if all black holes eventually evaporate in a finite amount of time?

The centre of the universe appears to be my head. I see the same distance in all directions.

Does this oscillation require some sort of interaction with matter? If so, you would expect it not to oscillate in open space. Maybe it conserves energy when it interacts as not to violate it?

it's indirect. It modifies the oscillation vs. propagation behavior in a manner that is inconsistent with 3 states. It's kind of light shinning unpolarized light on a birefringent crystal...you instantly see that light has two different propagation states, but there is no room in the observation to accommodate an unseen 3rd state.

@@markstyles1246 That depends on how close to the speed of light the average speed is. The closer, the higher the temperature. There is no "highest" temperature there, as you can get arbitrarily close to the speed of light (90%, 99%, 99,9% etc.).

is the difference just that sterile neutrinos would be right handed? is it possible (or just consistent) that there would be three generations as well, we just don't expect them to be generated or seen because the weak force is restricted to left handed fermions? this is confusing stuff 🤔

Dude, happy New year 💚☘️🌈 yummy 😋

As Mr. Spock says; fascinating.

Is there any likelihood that detecting the neutrinos is somehow affecting their oscillation behavior?

you have a video about a cat turning into a jaguar and then into a tiger and then back into a cat? great! I'll have to watch that.

Good luck with the new program! I hope it gives great results, whatever they may be. Proper time is a kind of spin. Antiparticles have the opposite spin to normal particles, and thus go "backwards" in time. Proper time is also the source, or reservoir, of potential energy.

the real question is, does the black mesa research facility exist, and why you've changed it for working at fermilab dr. lincoln ?

Imaging Cosmic And Rare Underground Signals has to be the most tortured acronym I've ever heard, but I'm looking forward to seeing how well it flies.

Do you think there is a Sterile for each cousin element, and perspective is the reason they can't be seen... like a 2 way mirror works, in essence.

So to be clear in the experiment diagram at 7:11, in between the three facilities the neutrinos are just passing directly through solid earth, right? I know that's regular for neutrinos but it's still pretty funny

Out of curiosity, a quick Google of solar neutrino flux yielded: "The flux of solar neutrinos at the earth's surface is on the order of 10^11 per square centimeter per second." I can't help but wonder how on Earth (literally) can any experiment discriminate between that density of background neutrino flux and those produced by Fermilab? Is there a good source of info on that?

The neutrinos in the beam are all focused in a very small fraction of a second. In addition, they are much higher energy and beamed in a specific direction. Imposing those criteria basically rules out all solar neutrinos.

can a global network of high-performance neutrino detectors identify, locate and track sources such as nuclear weapons or nuclear submarines in the deep ocean?

Since neutrinos are associated with their corresponding leptons, might a sterile neutrino possibly imply the existence of a 'sterile electron'? Something with the mass of an electron but no charge? And stretching things further, could such a thing be a candidate for at least part of dark matter?

The short answer is no... in the standard model, but technically, the sterile neutrino is not predicted by the standard model either, but there is a very conspicuously absent right-handed neutrino while electrons (muon, tau) come in both left and right-handed versions. The long explanation has to do with the Higgs mechanism breaking electroweak symmetry, and I'm not going to try to summarize it here.
