Astronomers think there should be 5 times as much dark matter as ordinary matter - a shadow universe that makes up most of the mass in the universe. But after decades of trying, no experiments have found any trace of dark matter - except one.

Had a good friend working for his PhD for the Italian side of the project. The material science is insane. They used copper from old sunken ships for a lot of the hardware, because it is way less contaminated with radiation. Super interesting projects and marvelous engineering
That's so cool!
It is steel that they use from the ships that were sunk before the nuclear tests, or any iron that was made before then.
You made me post my first youtube comment. Ever. ;) We use lead from sunken Roman ships. But that's super rare, so it's really only used in the CUORE experiment for some of the shielding, and for soldering stuff in some specialized applications, such as in CRESST. Old iron is too brittle. And copper can be made extremely clean using electrolysis (and even cleaner doing the electrolysis underground)

@@Foolish188 and that’s how the dark matter age of humanity will begin , dark tech ? 🤣
we know what to look for because dark matter interacts gravitationaly, which is a thing we can measure. it's like being blind but looking for the fire because it radiates heat.
More like telling a person from the stone age that they might get a shiny surface from heating up certain rocks hot enough. So long as they keep seeing rock after the fact, they will try to better insulate the rock or try to find other samples. When one finally melts, they may see a semi-shiny surface and assume, correctly, that they are close. They will likely then try to perfect smelting techniques to get a better finish/metal over time.

"It may elude us, but at least we tried."
That right there is what science is all about. Loved that quote.
Having evolved as sentient beings, in a universe where some things might never be detectable or provable, is the ultimate cosmic irony.
That's one of the great things about science: even if an experiment fails, it may still be a win because of the interesting data gathered in the process which in turn may lead to fascinating new discoveries.
So the most important science quote isn't "Heureka!", but: "Hey, that's funny..." - because that's how _every_ expansion of knowledge begins. 🙂
ok
Luminiferous aether has eluded us for almost 200 years.
But when you are well and truly aware of the electric universe model, it is pretty much the dumbest statement ever.
Really loved this one, not only this being a question that has been haunting humanity for years but to see the excitement of the scientists in the field of study. I'm excited to see the result of the mirrored Dama/Libra! It might just indicate that they've been dectecting something else but the mere possibility that it will give similar results to its sister machine is life-changing.
Whoever took those points on the original wave and connected that with to dark matter is a genius

WOW Derek what a brilliant, easy while thick, luminous while talking darkness, open episode of Veritasium You did! Simply Thank You. In the first animation you answered so many 'never dared to ask' questions i had about motus, speed, momentum of the Solar system travelling through empty space, and in the end a clever openess: let's see 🙏🏻❤️
This is an incredibly oblique yet straightforward comment, bulky in the edges, yet so thin in the middle. I almost couldn't see it even though it was so large.
I'm a PhD candidate working on DM and I think this video was great. I see so much discussion online where people assume scientists are just being narcissistic when we assume DM exists and that it must be like the new version of luminiferous ether theory, because they're not in tune with just *how much* **independent** evidence we have that is cleanly explained by particle DM.
My only gripe with the entire video would be that I wish you had mentioned specifically that the idea of a particle "we can't see" or being "dark" isn't absurd in the slightest--I think part of why laypeople have gripes with the idea is that they think it's absurd that we could just posit something "invisible" is there. In reality, we already know of MANY particles that are similarly "invisible"--like neutrinos! In this context, "invisible" just means "doesn't interact with light" which is precisely true of neutrinos, and yet we are bombarded with trillions upon trillions of solar neutrinos every second from the sun. Unfortunately, we are not so lucky that DM is as easy to detect as neutrinos :)
My prediction: A simple discovery by the JWT will finally put an end to DM. Better have a backup plan.
Look I’m suspicious of dark matter theory because, if you’re going to try and invent an entire new class of particles that supposedly only interacts with matter/light through gravitational force alone, but there’s zero and I mean ZERO evidence that these supposed particles exist………
COULD (particle) dark matter theory turn out to be correct? Absolutely, yes, but forgive me for being suspicious of a theory that frankly has zero evidence in support of it
We KNOW beyond reasonable doubt that there’s plenty of mass unaccounted for in our universe, this is true, and I also am suspicious as hell of MOND because (just like particle dark matter theory) it’s an ad hoc explanation with no real evidence to support its validity……
My basic point is this: Don’t think that the ‘opposition’ to dark matter theory is because it’s weird and people can’t ‘see it’ because quantum mechanics is absolutely weird as hell, but it’s true it gives very precise predictions and is verifiable and testable through endless experiments
It is frankly unscientific at the core, to believe in particle dark matter theory as anything more than a POSSIBILITY, unless and until there is evidence for it
We’ve spent years and billions of dollars building dark matter detectors and as of yet, nothing………
Again I’m not saying (particle) dark matter isn’t real, and it MIGHT be the best explanation we’ve so far come up with, but unless and until there’s actual evidence for it……. Forgive me for being a skeptic 🤷🏼♂️
Fascinating!!
Though, something does not exist until it is proven to exist. It is possible we will "will" dark matter into existence because of how well the concept fixes our problems, but it is due to something different entirely.
All so fascinating.
This is not just about it being invisible but also intangible and only interacting through gravity.
Sometimes I feel ashamed to be a human, but sometimes I watch a Veritasium video and pride comes back.
The means deployed to find the secrets of our universe are amazing.
And it takes so much humility to say "it may elude us, but at least we tried"

I was supposed to be writing my articles for my Masters Degree classes rn. I've been watching videos all afternoon. This is probably my 20th video. It's 10PM and I wrote nothing. (*presses play button)
So, a year down the road since this was posted now: have they been able to reach any sort of conclusion in Melbourne? Thanks for updating us, Derek.
They only started data collection in early 2023, so it's probably going to be a while before results are published.
Moreover there are other experiments trying to replicate the DAMA/LIBRA results, and one from south korea (COSINE-100) managed to "in a way" replicate the results. I put this in quotation marks because with their initial data analysis method they got a null result (aka: they found no signal whatsoever) but then they took their data and analyzed it with the somewhat particular data analysis method DAMA/LIBRA used in their publications and "found" a signal as well.
Problem: This COSINE-100 signal is almost the inverse (the phase is flipped) of the original DAMA/LIBRA signal, so this is no good news for the dark matter theory as it might be some other effect. Or even worse, the signal might have been induced by the data analysis method itself and be completely arbitrary (low frequency noise generated by the photo multiplier tubes that is not modeled/compensated correctly).
For more info just google "An induced annual modulation signature in COSINE-100 data by DAMA/LIBRA’s analysis method", the paper is freely available, short, and the non technical part relatively easy to understand

Thanks for a great vid!!
But we must know, we will know!
Okay normally I would agree with you but "Dark Matter" is such an obviously false and dumb theory that I have to say all the money dumped into finding a clearly non-existent particle was truly wasted. It's a bad theory that tries to crowbar a mystical magical particle to fill in the gaps of our understanding of gravity on large scales. They were NEVER going to find one and surely that was obvious from the start.
that statement made me laugh .. It felt more like "than why bother"...
We have to live with possibility, we have to be optimistic, we have to hold our hopes to make it happen...
there is much more important things to know right now, the money would be better spent dealing with useful work, rather than looking for something that is so elusive no one has made any observation of it.
It's comforting to know that this kind of research is being done. The kind that doesn't have any clear economic purpose, but instead is just for the sake of the pursuit of knowledge.
This is a very important point! It's not obvious that a civilization would pay for this.
amen brother
There isnot a single research which don't have significant important. Sooner or later we are going to find the use of dark matter and it is gonna pay off. It just like 16th century people thinking what is gonna do good by learning about space and stars.
Billions of dollars in grant money is not economic to you then?
dark matter is actually just the medium in which consciousness exists, aka it is the soul. that is why it can be found in mountians/ancient volcanos where xinu deposited souls at the beginning.

I’m physics graduate and at one time in my life, very recently actually, I used to want to be a scientist. When the time came around for me to choose my Masters, I chose to study Dark Matter. It was almost my whole life for nearly three years, but academia just wasn’t for me. Coupled with the pandemic, I quit for the sake of my mental health and am much happier now, but man. Hearing all the names of the experiments, of the physicists involved, the history and development of the theory… It takes me back you know? I still love physics, I still admired it and I still understand it. In a way, I miss it, but I don’t think I want to be a scientist. I’m happy just reading articles every now and then, remembering what I spent years studying, revisiting a huge part of my life.
I kind of lost track here. Anyway, I just wanted to say thank you for the video. It almost feels like one last visit before leaving a place I know I’ll never be in again. Thanks
academia is switching your brain from analog to binary.
Conduct your own little experiments bro, if you can. Make humanity proud.
That's kinda sad but yeah absolutely alright, keep doing whatever you find happiness in! And if you think there really was something serious that held you back from pursuing your true interests, don't worry man you got this. You'll sure get it right this time.
Man, I feel you. I specialized in theoretical particle physics with dark matter in mind for my entire masters programm. Now I'm starting my thesis in nanooptics because I think I'm not cut out for writing down theories that might get experimentally checked several decades from now. I needed something more tangible you know?
But I still miss the stuff. Nice to know that I'm not the only one.
I 100% agree with you, I recently finished my masters before running away from acadamia. It was interesting hearing about DAMA/LIBRA again in an optimistic light, i got so used to hearing people say, "yeah but no one else can repeat it" and dismissing it you forget that they have discovered something even if it is just tourists cause DM detector interference.
Saying Brilliant is everywhere and interactive, is one of the best sponsor intros relative to the topic I have seen
If Dark Matter didn’t interact with itself at all aside from gravity, wouldn’t it end up piling together into singularities in places? If there aren’t repelling forces to keep particles from occupying the same space?
Could be
Okay so exposition time from someone who's currently working on dark matter densities. If dark matter does interact with itself, then yes there would be the dark matter equivalent of friction and dark matter would slowly migrate to already dense places in the Universe. This is because friction is the result of particles colliding/interacting and re-distributing their energies, and changing the energy of a particle alters its trajectory. However, we have no evidence (that is significant and that I know of) for this dark matter self-interaction.
Think back to the Bullet cluster example. If the dark matter did self-interact significantly, it would have behaved more like the ordinary matter; colliding and getting stuck in the middle. This didn't happen, and instead the dark matter clouds passed through each other completely unfazed. No significant self-interaction means no way of re-distributing energy, and thus dark matter particles don't alter their trajectories once they're on a set path. This means that the only dark matter particles that would end up in singularities, are the ones that were already going to collide with one head-on, and the radius of no escape from a heavy object is very small compared to the rest of the Universe. So yeah, that's why we have dark matter zipping around all over the place.
@@paulthomas963 Curious, why do you think forces arent carried by particles? And why do you think degeneracy pressure should be a fundamental force when its just an extreme manifestation of the pauli exclusion principle but the Strong/Weak forces shouldnt be fundamental forces when they describe how atoms stay together?

gravity itself, we observe space-time curvature. in a group of billions and billions of stars, that ákes a lot of curvature, including a slower time, slower speed, hence the center of galaxy appears in sync.

The lab where the Dama/Libra is locates is called INFS (istituto nazionale fisica nucleare) and they also tested neutrinos’ speed with the CERN in Ginevra.

You know that if you put Dark Matter in a translater to the german "dunkle Materie" you can actually hear how it is pronounced.

I imagine scientists made out of dark matter are setting up similarly complicated experiments to try to detect this mythical "regular matter"
😂
I love the idea that their world has played out so exactly the same as ours that they actually have the same English language, except by some quirk they call themselves "dark matter" and call us "regular matter"
That's racist.
we would be like dark matter to them
Dark matter doesn't interact with itself so I don't think it can form the same structures as ordinary matter

I must add, one of the interesting facts about the Universe🌌 is, if the rate of expansion of the Universe would have changed just only by one part in a Quintillion after the Big Bang, a Quintillion is one with 18 zeros after it, 1,000,000,000,000,000,000, then, the Universe would have continued to expand or collapsed back on itself.

The correlation between the dark matter peaking in june and November and the increase in chances of getting hit by a meteor during those same months is spooking me out 😮
They literally explained it tho if your flying through space faster your way more likely to hit things than when you go slowly lmao
Some things are coincidentally similar, though
@@matthewplizga1920 Eh but aren't you more likely to avoid getting hit by things too, because you could get out of the way faster? Also consider this: it's a well-known idea that if someone is trying to shoot you, run in a zig-zag, not a straight line. Doesn't matter how fast you run, what makes you an easy/hard target to hit is the direction that you're moving.
My point is that there are more factors that can affect how easy of a target Earth is -- not just its speed.
@@suubisuubi No. Moving faster through space makes you more likely to impact stuff. This is a well established principle, there's plenty of videos and explanations on it with good visuals. Zig-zagging doesn't matter at all, so long as the speed remains constant. Also, meteors don't aim themselves. They just exist in space at some velocity, and if earth exists near them, they will impact earth.

That ending statement is powerful. Sometimes there will never be enough evidence for an absolute certainty. At least not in this timeline
I have to get this out: "Dunkle Materie" is literally just the German words for dark matter and every letter in it is pronounced in the order it's written and without any alterations
We cannot see the ubiquitous creation of matter 'particles', but they are happening everywhere as wave-motions of space..
"Commendation from NASA for research work at Massachusetts Institute of Technology on the Earth's atmosphere and the Moon's surface for navigation of the Apollo spacecraft to the Moon..
Dr. Milo Wolff has found the structure of the electron consisting of two spherical quantum waves, one moving radially outward and another moving radially inward. The center of the waves is the nominal location of the electron 'particle'. These waves extend infinitely, like charge force. All 'particle' waves mix and contribute to each other, thus all matter of the universe is interrelated by this intimate connection between the fundamental 'particles' and the universe. The natural laws are a direct consequence of this Wave Structure of Matter (WSM), thus WSM underlies all of science."
"Mathematics has the completely false reputation of yielding infallible conclusions. Its infallibility is nothing but identity. Two times two is not four, but it is just two times two, and that is what we call four for short. But four is nothing new at all. And thus it goes on and on in its conclusions, except that in the higher formulas the identity fades out of sight." (Johann Wolfgang Von Goethe)
"Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality." (Nikola Tesla)

Excellent, as usual!
Just a note on geography. The Italian Alps are the mountains that separate Italy from France and Switzerland. The mountain range that goes down the spine of Italy is called the Apennines. DAMA/LIBRA is located under the Gran Sasso, specifically the Corno Grande, which at 2,912 metres of altitude is the highest peak in the range.
Is that the one that's causing problems to the local water supplies?
Aaaaannnnddddd... this is why I switched from particle physics to condensed Matter physics. I personally do not have the patience to run an experiment that is like this. Intentionally trying to detect something that doesn't interact much by definition sounds like a frustrating experience. The same goes for the the neutrino community.

What a great Veritasium video!
i've lived near the italian detector for years and it is absolutely amazing to discover so much time later what did they do and discover inside that laboratory. There is a gallery which passes just trough the gran sasso and in that you can see a door with written "INFN Laboratory". I've always been curious to discover in what is at the other side of the door but it is almost impossible to enter in there whitout any specific pass.
I just wrote a massive thesis about dark matter'ss density within the universe (rather than detecting it on Earth, like this video is about)! I'm very glad that you mentioned Vera Rubin, the absolute legend, in the discovery of dark matter (4:26) -- she's often left out of the narrative for no good reason, but she is such a key and integral figure.
The LSST was renamed after Vera Rubin, so she finally gets her recognition :) btw what exactly was your thesis about?
Discovered dark matter you say....
@@kevinpils4716 I wrote about the structure of low surface brightness spiral galaxies, getting my research group a couple steps closer to properly modeling our galaxies’ dark matter haloes! My thesis was a part of a larger project, working on evaluating core-cusp transformation of dark matter haloes. Hopefully, we’ll have it published within the next couple years :~)
@@bogbutter can I have your report?
@@bogbutter In my humble opinion, science started with the telescope/microscope for a reason. What you can't see (well) you can't test (well), and what you can't test is not science. Statistics aren't all powerful and won't fix a blurry image (it's not possible to zoom in the pixels of an image like in a movie), what they may actually do is create fake information (see ML up-scaling).
So in conclusion, anything too big to see properly in detail (such as galaxies) or too small (such as the quantum world) is not science, and will not be science until we figure a way to see properly (one that doesn't rely on statistics). Until then we may have theories, but those ain't better than the theories we did in the past about the earth being flat. Instead of focusing on making theories and more theories, we should focus on making machines too see properly.
"it may elude us, but at least we tried." The essence of experiment expressed in a single sentence.

I knew that someone pointed it out in the comments xD
Kinda hurt my german speaking soul
Knowing what he was trying to say, and hearing "Dankel Matterie" was bizarre. I am confused how this can happen on a channel that focuses on research. It's not like there aren't phonetic spellings, tts softwares and native speakers to help with the pronounciation.

I love the bit explaining why the current consensus is for the existence of dark matter instead of our understanding of gravity being wrong or incomplete. It seems to be the number one question for people who have gained at least a cursory understanding on the phenomenon.
Well there are a lot of things that we "know" that can be wrong... in phisics most of them comes to gravity, and time...
Same. I'm more wont to believe that our understanding of gravity is wrong rather than the existence of a large amount of invisible matter, but the explanation shows that there's more to it than just "our data is not lining up with our theories". I guess the thousands of intelligent physicists around the globe who know much more about this topic than any of us would have thrown away the dark matter hypothesis if there were no such convincing evidence.
@@Cuestrupaster Yes but the thing is, like Echo.120 expands below, is that with what evidence we do have it seems to be much less likely that our theories have a fundamental issue with them.
This thing always pops up in the comments on videos about dark matter, hence why I made the comment in the first place. And I do understanding why it's appealing to think that it must be the theories that are wrong, since we have no direct detection after 90 years of having seen the effect. The human mind likes pattern detection, and for the layman it seems like there is no pattern.
But the scientific consensus on the matter has been formed by people who have spent *literal lifetimes* studying the topic. And the evidence they've found points towards dark matter being real, whereas the other other option has way less evidence. So surely it makes sense to pursue the one that has some merit to it, instead of going on a wild goose chase just because we've found nothing so far?
@@echo.1209 Precisely! It's very appealing to look for explanations elsewhere.
@@echo.1209 um...i guess, but they don't all agree. Check Sabine Hossenfelders videos on it. Basically, yes reject MOND but that doesn't mean its possible for a future theory to correct the disrepecy and nor do they know the exact candidate of dark matter to fit (none proposed quite work perfectly...). Plus, there are multiple other reasons to look at our theory of gravity from dark energy to disrepency with quantum mechanics anyway.
even if the experiment shows nothing, that's something
Love the vid. Derek Muller's final question is funny: "Do you think that dark matter interacts with ordinary matter?" The reasons scientists have posited the existence of dark matter is that ordinary GR gravity/curved space-time is inadequate to explain some observed phenomena, such as the speed of stars at the outer ends of galaxies. "Dark matter' is shorthand for saying 'there must be some other matter that we can't see out there that's interacting with ordinary matter.'
Meanwhile, in another part of the Universe: ‘I really like the idea that because 20% of the mass of the Universe is Dark Matter, maybe there is an entire Dark Standard Model if you like.’

Good thinking outside our infinite 📦
Technically it's more like 15.63% if viewed from someone in the dark matter universe. But I like to think there's not just two guys out there speculating, but instead six guys all covering only 15.63% each, all looking for the other 84.37%.

Wow I actually did a seminar on this last semester and especially held a presentation on DAMA/LIBRA. What might additionally be interesting to know is, that there are already two experiments currently running, which try to independently find the same signal as DAMA/LIBRA, named Cosine100 and ANAIS. Both have around three years of measuring time and are starting to become able to judge if the DAMA/LIBRA signal can be reproduced. So far the results of ANAIS seem to indicate no signal can be found, while Cosine is not yet able to make a clear statement, since the bestvalues for certain interesting parameters lie inbetween the zero hypothesis (there is no signal) and the DAMA/LIBRA finding. So right now the trend is leans towards the signal not being due to dark matter, but only time and more experiments will tell, if this ts the case.
where do i get updates on the experiement he talked about in the video?
God bless the guy who decided to call it ANAIS ehauheauehauhaeauheuhuhue

Speak for yourself
"History abundantly shows that people's views of the universe are bound up with their views of themselves and of their society. The debate in cosmology has implications far beyond the realm of science, for it is a question of how truth is known. How these questions are answered will shape not only the history of science, but the history of humanity." (Eric Lerner, 1992)
One of the main reasons 'big bang' is pushed so ferociously is that it has been endorsed by the vatican..
"In fact, it seems that present-day science, with one sweeping step back across millions of centuries, has succeeded in bearing witness to that primordial 'Fiat lux' (Let there be light) uttered at the moment when, along with matter, there burst forth from nothing a sea of light and radiation, while the particles of the chemical elements split and formed into millions of galaxies ... Hence, creation took place in time, therefore, there is a Creator, God exists!" (Pope Pius XII, 1951)
300 years before this, 'the church' had Giordano Bruno publicly murdered for saying that space is infinite..
You 'do the math'.. NO! Please don't! This is why the erroneous ideas of 'infinity' are used in mathematics, specifically to confuse people into a misunderstanding of what infinitude actually means.. If space is infinite, 'god' cannot be..
They found nothing, otherwise it would be all over the news.
The longer people keep shutting out the possibility the universe is designed, the further they get from any sort of light. Dark indeed.
