@J Thorsson Hi. Just commenting to say I recognized the bucko immediately. I wasn't gonna comment but read this last one and decided to answer. I'm only one person but I'd imagine there's a decent overlap. I hang around on both science and philosophy channels. I will say I'm not a Peterson fan, not really a hater either though. He's too obsessed with Postmodernism. Still glad you got something useful out of him. I'm all for self improvement.
@J Thorsson If I understood your first reply correctly... Yes, I agree our culture treats reason and emotion as opposing forces. I don't see it that way. As for politics... your guess is correct I'm more on the left, big qualifier, for an American. But my first priority would be on the libertarian-authoritarian axis. I'm not religious myself either. But I do agree with Peterson on the importance of meaning and purpose. I just wish he'd stay out of the woo. I'm not really upset/offended/etc by him. In fact following, understanding, him helped me clarify my own views. Which is something I imagine he'd like. Still his personality is very unsuited to politics or high public exposure. I hope he retires to a more quiet life and doesn't end up a martyr.
I literally just binged all of Don Lincoln's videos last week so this crossover is a hugely welcomed surprise! Thanks Space Time and Fermi Lab for this great crossover!
This episode was far too short for how amazing it was. I love me some collabs and one between Fermi and Spacetime is amazing. Definitely need more of this!
"We love you" "And we love you" "And that's how you study the most elusive particles in the universe" Love confirmed to be the most important part of science - you heard it here first, folks! PBS Space Time approves of your public displays of affection!
If only I had seen this video a few days ago. I've just been on board the experimental particle physics express for knowledge's sake, and tried to explain to someone at a party why it was exciting that we were doing neutrino research. Then they asked "well what can we do with that?" And I had to concede that I did not know. And now thanks to this I do, after the conversation *sigh*
If it wasn't a geek party, the additional knowledge would not have helped. Fear not, we can be your Spacetime party friends. No matter what that other guy was trying to pull.
But doesn't that perfectly fit the laws of entropy?!? I mean. You can't have the answer before the question is presented. The universe just doesn't flow that way.
I visited this lab in college. One of the most amazing things. I wanted to add some details. The detector is actually tons of little cells, filled with the liquid which creates a blue lights when a neutrino hits it. The neutrino beam actually has two particles, as it travels, it splits and there is another lab being built to detect these that split from the straight beam. The cell detectors use fiber optic cables to detect these tiny blue lights and all these cells are than mapped out. I asked, so how do you know that the particles and neutrinos and not something else. We don’t know, just that it is far underground so limits possibility of most other stuff. Now, out of these trillions a second, I believe it was something like 1 or 0 neutrinos get detected per day. The amount of neutrinos detected was very low. Now the following is my own opinion and I am not physicist: we don’t actually know what these are or what is being detected, these theories aim to describe a natural phenomena, that is the extent of its truth.
@@doktormcnasty The best, all the people are talking about it. You know, nobody new about particles before but all of a sudden Im like, bing bing bong bong Particles, tiny particles And my scientist, big strong guy, a biker, comes up to me and says "sir"...hes crying, tears running down his cheek "sir, youve done more for particles than any president"
For some reason it just blew my mind that you can draw a line from your feet any angle down and it will eventually reach a point where it goes OUT of the earth, without curving. Makes me unnervingly aware that I’m just attached to a huge ball floating in space
They're being successful at trolling humans. If they were either massless or quite a bit more massive, our theories would work. But their mass just happens to fall in a very narrow range that completely screws with us. They're doing it on purpose.
@@lordgarion514 Read a post on reddit some guy made about neutrinos being proof that God is a complete ass. Funny to think of this being the kind of exasperated humor the standard model is directly responsible for.
yeah, but it also contains a lot of empty space. Kinda makes you wonder, if there was that much mass at the beginning, such that what's left over is considered a tiny amount, why didn't everything just immediately collapse into a black hole? And why isn't the cosmic microwave background, the cosmic X-ray background instead? /shrug
@@DFPercush its all relative though- objects like stars or galaxies may seem like they contain a LOT of matter, relative to the objects we're familiar with here on Earth, but compared to the space between them (the space between star system and star system, galaxy and galaxy, galactic cluster and galactic cluster, etc.) they are absolutely minuscule. The average density of matter in space is only something like one atom per cubic centimeter!
I love how Don casually says they are going to send a super intense beam of neutrinos through the Earth from Chicago to South Dakota to a detector one mile underground. The engineering that happens for these enormous Physics experiments blows my mind.
Just off camera, there was a crew of exuberant, extroverted and impeccably dressed homosexuals "updating" the test chamber with recessed lighting fixtures and adding a hide-away chest of drawers to the muon source. 🤔I assume next week they'll add a _cozy little breakfast nook_ to the protons.
With 10x the budget, they could build a more efficient system and increase their detection rate 25x over. It would answer the same questions but faster.

I watch a lot of youtube, but i can honestly say, this by far has been my favorite chancel since i found it six months ago or so.Thank you for helping me expand my mind by making such amazing content. i look forward to more amazing videos to come.
I know this is a case of Dunning-Kruger effect, but I always thought that the question why there was more matter than antimatter would be neatly explained by something resembling the bubble universes. What I mean is there is a random fluctuation in the matter/antimatter ratio in any given volume of space, but the “global” ratio would still be 1/1. We just live in a local bubble that happen to have the ratio marginally to the mater side, but because of the inflation and space-time expansion we would be never able to observe other more balanced (or even anti-matter heavy) patches of space. I know this is untestable /probably/. Also, I know that people who actually have years of studies and published papers on the subject must have entertained that idea (because, despite my mammalian instincts to the contrary, I am not the sole person capable of coming up with that), but I've never heard it discussed or proposed - please do tell me, why is that so. Is there some obvious /obvious to astrophysicists/ reason why that idea is pure nonsense, or is it just too speculative and philosophical in it's nature that it's not really worth being talked about, or maybe something else?
IANAAP, but if there were clumps of matter clouds/clusters/galaxies and antimatter clouds/clusters/galaxies, we should be seeing more gamma ray sources when they run into each other. And we have seen many examples of galaxies that have collided or will collide or were involved in a past collision. Now one could argue that perhaps a matter/antimatter split happened early enough in the history of the universe that cosmic inflation spread the matter and antimatter clumps apart, but we can also look for primordial gamma rays and use that to establish lower bounds for this hypothesis. AFAIK, there aren't many proponents of the hypothesis that there are equal parts matter and antimatter in our observable universe.
It is extremely improbable (to the Nth degree) to have such a large clump of mostly matter only because of a statistical fluctuation. It would be like flipping a coin N times and have it always come up heads every time where N is the number of particles in the Universe. Might as well say "God made it that way". Yes, if you have a large enough meta-verse to form the bubbles in then it's possible to have such unlikely bubbles but you would still need to explain why were are in such a very unlikely part of the meta-verse. Almost any weird experimental result could be chalked up to being an extremely unlikely statistical anomaly but saying that is basically giving up on science. It's more fun and interesting to see if there is a less unlikely explanation.
BitJam that is not what he is saying though. Due to the expansion of the universe, the ratio between matter and antimatter interacting at the time of the Big Bang needed to make our universe possible is very close to 1. So even an extremely small fluctuation in an inflating universe would produce a bubble. And I think this concept is actually explored in inflation theory but I'm not sure it is been taken in account very much.
@@Vasharan Just to make myself clearer, I was thinking of the bubble with marginally more matter being at least one order of magnitude larger than the observable universe.
Well... when you scale up your PC size to several kilometers, and you only use non commercial custom DIY parts... your aesthetics taste of PC gamer, shifts towards more refined dystopian steam/cyber-punky sides..
I do not understand much since i never got the chance to study physics properly but I follow every content you make and little by little i learn something , thank you for the great video
A universe full of photons isn't exactly nothing. It's nothing _useful_ but it's not nothing. So the philosophical question "why is there something rather than nothing" was deliberately twisted here for there to be a scientific answer rather than a scientific ¯\_(ツ)_/¯. And while this might feel more satisfying on a surface level, I honestly hate it when people do this. It's imprecise, it muddies all sorts of waters and it's honestly a style of science communication that usually not to exhibit is a big part of what makes this channel so amazing to me.
Basic questions go unanswered, like: what's so special about Argon that it's the "choice" atom to detect neutrinos? Why even mention it if it goes unexplained?? Just call it "a detector" and be done with it.
Certain nuclei are more prone to interacting with neutrinos than others. For example deuterium requires a high energy neutrino to split it into two protons but tritium will interact with any energy neutrino to form helium 3. Argon-40 is a susceptible nucleus that requires no purification, is common and can form a liquid through which signals can travel easily.
Thanks! This looks like some sort of neutrino's "chemistry" - a phenomenological approach on how neutrinos interact with different nuclei. The difference from actual chemistry is that chemical substances interact via valence electrons, i.e. through electromagnetic force rather than weak force.
Matt, thank you!!! The missing silly intro music and slower pace of talking is greatly appreciated. One of the reasons I enjoy Don's videos is his tempo. I have to watch both your videos many, many times to absorb them all (which I do), and the music and fast pace can grate on my nerves. Also, my two faves together! Thank you a lot... Sara
It's fun to see these two communicating with the same dramatic pauses and inflection that they use in their videos. Kind of like Siri and Alexa having a conversation, except more entertaining.

I do not understand much since i never got the chance to study physics properly but I follow every content you make and little by little i learn something , thank you for the great video
Ahem.
Most elusive particle *that we know of.*
😉
A universe full of photons isn't exactly nothing. It's nothing _useful_ but it's not nothing. So the philosophical question "why is there something rather than nothing" was deliberately twisted here for there to be a scientific answer rather than a scientific ¯\_(ツ)_/¯.
And while this might feel more satisfying on a surface level, I honestly hate it when people do this. It's imprecise, it muddies all sorts of waters and it's honestly a style of science communication that usually not to exhibit is a big part of what makes this channel so amazing to me.
Who You Gonna Call: Ghost Particle Busters
Thank you for this episode. Don is truly one of the great explainers of our time.
This episode feels a bit too heavily cut down.
OH MY GOD(NESS)! Dr Lincoln on PBS Spacetime, at last!
After 5+ years of following FermiLab and PBS Space Time, my wish has been granted!
Everybody knows that it borrows its energy from the future and pays it back when it's interacted with..
Is that why they avoid interacting? Because like most people, they don't want to pay up and give up the ghost?
Double take! Two of my favorite UA-camrs -- in one video?!? So happy right now... 😭😭😭
Am sure, i have lots of particles in my vacuum cleaner
OMG, I love this guy! Great team up!
Basic questions go unanswered, like: what's so special about Argon that it's the "choice" atom to detect neutrinos? Why even mention it if it goes unexplained?? Just call it "a detector" and be done with it.
You should be a sit-com director classic!
My guess is that it's a cheap noble gas.
Fermilabs and PBS Spacetime ?? Oh my god-particle, this was awesome
Why do they use liquid argon?
Certain nuclei are more prone to interacting with neutrinos than others. For example deuterium requires a high energy neutrino to split it into two protons but tritium will interact with any energy neutrino to form helium 3.
Argon-40 is a susceptible nucleus that requires no purification, is common and can form a liquid through which signals can travel easily.
Thanks! This looks like some sort of neutrino's "chemistry" - a phenomenological approach on how neutrinos interact with different nuclei. The difference from actual chemistry is that chemical substances interact via valence electrons, i.e. through electromagnetic force rather than weak force.
Cross over between 2 of my favorite youtubers!
I can finally say “I believe in ghosts” thanks science!
The greatest crossover event in all of physics!!
Who you gonna call??
Ghostbusters!
To see these two guys together is a special treat! Now do a cross-over the other way!
"Why is there something rather than nothing?" Next you will be asking whether the universe is nothing more than the product of my imagination.
Well if you think it therefore it is.
You may have a point there, or did i imagine it?
The universe the product of your imagination? That's silly. It is the sum.
Richard Braakman Isn't it the convolution of one's imagination ?
Dr. Don Lincoln! This is the biggest crossover yet! Fermilab + PBS Spacetime!
Matt, thank you!!! The missing silly intro music and slower pace of talking is greatly appreciated. One of the reasons I enjoy Don's videos is his tempo. I have to watch both your videos many, many times to absorb them all (which I do), and the music and fast pace can grate on my nerves. Also, my two faves together! Thank you a lot... Sara
It's fun to see these two communicating with the same dramatic pauses and inflection that they use in their videos. Kind of like Siri and Alexa having a conversation, except more entertaining.
Oh wow...Spacetime and Fermilab in one video! Definitely a box checked there.
Oh my jesus lord I can hardly believe it, I hope this is the first collaboration of many!
