As a potential ghost in 2030, this is an invasion of my privacy.
You talk as if we still have privacy to be invaded.
@@Jossandoval ... occupation of my privacy, then?
Schrodinger Cat is in two minds about this
@@Jossandovallol speak for your self, some of us take a lot more precautions than others

Of course they're using proton beam to catch "ghosts". Life imitates art again.
Don't cross the streams
The new one just come out in cinemas
One imagine that the scientists naming this project were well aware of that movie reference. Pretty clever.
Who you gonna call? CERN!
Ahhhh, nice to see some coverage for our lovely detector! I'm from the SHiP collaboration and worked on the electronics for detector - and boy, this will be fun. Thank you for covering our work!
Wavelength the size of a galaxy! Now that wave function collapse would be spooky action at a serious distance. That guy's head would bobble off his body.
hahahaha 😂
That would need one huge CB antenna, good buddy. Keep your shiny side up, and your dark matter down.

These are ghost particles, of course they are spooky.
Indeed.
Sabine: Can we please stop calling them "ghosts"? Scientists: ok, lets call it "Magic"
Never let scientists name anything.
I'm just glad they're not looking for hidden Tachyons - That acronym would have to be re-thought!
You are talking about the Baryon Utilizing Large Lasso to Search for Hidden Tachyons?
@@SiqueScarface Yes well spotted! Although I would imaging we're also talking Capture Radius Aperture Protocol.
@@steveellis2829It could be Well Oriented Research into Singular Events.

Sabine, when i heard this story i thought, how can they write a piece that tells me, a scientifically literate person no clue what they are talking about. I eventually found that same experiment website. I then wondered if you would make a nice little video about it improving on the story and enlightening us all. So glad you got to it and glad i wasnt alone in being puzzled by the story.
But aren’t they always looking for hidden particles? If the particles weren’t hidden, we wouldn’t need to look for them.
No, you can’t get money by saying that you want to look for particles. You need something specific that many bureaucrats and scientists think is a good use of money. The days of just looking for things ended decades ago.
When a "particle" is spread out, like a densification of "aether," covering a wide area, like a waveform in a medium, and this is its ("particle's") coarsest possible state, then how could it be measured ? It is present; it is "dark", but unmeasurable (like "aether"). It is easier to say that: "It does not exist" (AS PARTICLE). It is a local quality of space rather than a particle. If, for example, we imagine that the "cosmological constant" has a local variation or transformation, how could it be measured ?
@@Lund.Jor how do you get away with calling it a particle at all :p
They aren't only looking for hidden particles. They also are examining the properties of the known particles more closely.
@@bjornfeuerbacher5514 those are usually funded.
Sabine, I used to comment on all your videos. As a psychometrician I feel we have quite a bit in common with physics (the whole measuring "invisible" things). Anyway, I can't do that anymore-you're on a roll these days. Thank you.
👋 Good to see you here!
To me, it's quite a human faith restoring thing that felt compelled to comment that. Thanks
@@SabineHossenfelder Hello Sabine, in your other video, you mentioned that you think most of the research done in your field, was BS. Do u also think this way ab the research at CERN?
I think it's indeed the best way to describe dark matter as ghost because nobody ever has a glimpse of it, and maybe I can finally interact with it after becoming a ghost upon my death years later lol... 👻
And it might not even be real, although what is these days? 😊
Dark matter is dilated mass. G.R predicts dilation not singularities. In the 1939 journal "Annals of Mathematics" Einstein wrote - "The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of G.R. predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters (star clusters) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light." He was referring to the phenomenon of dilation (sometimes called gamma or y) mass that is dilated is smeared through spacetime relative to an outside observer. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light". A graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light. A "time dilation" graph illustrates the same phenomenon, it's not just time that gets dilated. Dilation will occur wherever there is an astronomical quantity of mass because high mass means high momentum. There is no singularity/black hole at the center of our galaxy. It can be inferred mathematically that dilation is occurring there. In other words that mass is all around us. This is the explanation for galaxy rotation curves. The "missing mass" is dilated mass. Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. To date, 6 very low mass galaxies including NGC 1052-DF2 and DF4 have been confirmed to show no signs of dark matter. This also explains why all planets and all binary stars have normal rotation rates, not 3 times normal. The concept of singularities is preventing clarity in astronomy. Einstein is known to have repeatedly said that they cannot exist. Nobody believed in them when he was alive including Plank, Bohr, Schrodinger, Dirac, Heisenberg, Feynman etc.
@@shawns0762 Interesting, I have always thought that as well. "matter cannot be concentrated arbitrarily" Singularities are a result of the mathematics used to solve the equations. If a very large black hole got moving fast enough, perhaps space might rip apart. Anyway this video is interesting. Space is "something", and time as we consider it, is also somewhat an artifact. You can't measure it without expending energy. Energy state transitions have to propel everything. Perhaps the mathematical constructs and descriptions are flawed / limited in terms of actually describing reality. Perhaps a ghost math exists and we should hunt for that instead.
@@never2yield20 Einstein's reasoning on why singularities do not exist is solid as a rock. Television and movies popularized singularities beginning in the 1960's. The recent discovery that very low mass galaxies have predictable star rotation rates is virtual proof that dark matter is dilated mass.
@@shawns0762 Yep, the "dilated mass" is a concept I haven't heard of before. Guess I will have to do some research. My physics has gotten old. But I have never been fond of the "dark matter" explanation. I also find the large universal structures interesting. Does "dilated mass" explain or being applied to explain ? Singularities are a result of flaws in our mathematics. Infinities in a sense could be flaws. Since do they really exist in reality or are just needed to make out mathematical frameworks operate properly.
Awesome work, Sabine!
Wow. Most of us just search for Easter eggs at this time of year.
Interesting stuff! Thanks Sabine!
Absolutely LOVE the way everything is phrased in this video. :) As always, thank you! It also occurs to me when watching particle physics related videos how well researched (even if far fetched and fictional) much of the writing for Ghostbusters was. ;)
I think that in 5 years they have a nre project called Search for Hidden Targets.
Nre?
I can’t believe she said “bullshit” hahaha
You should hear her when she talks about politics.

She's German, no time wasted in getting to the point.

She says it as it is, bullshit is bullshit is bullshit no matter who you are. Brexit is bullshit too. So are many politicians.
You should have saved this episode for Halloween. 👻👻👻
It would have been thoroughly debunked by then😉
bless your heart
Title of the video has a question mark (?) Thus the answer to the question is always: NO.
Hidden practicals are also looking for creative scientists. I hope they find each others 😅
ive already seen several conspiracy theorys about how cern is gonna open the demon portal
Damnation. We were being very quiet about the Large Demon Collider. The Small Demon Collider was quite successful.
Goodbye Fermi paradox!
Still working on the BFG9000.....oh, yeah.
@@vilefly I now have the music from the original game in my head!
X is packed with cern conspiracy theories
Sabine, you are awesome. Thanks for your KZhead stuff.
Now I'm conCERNed...
xD
Had Ron elevated your conCERNes?
Womp womp
CERN , now specialising in proton exorcisms .... rid yourself of ghost particles now 🤣 {only 100m euro per service!}
seems a proton pack, or simply calling a priest, might be more cost effective
I commend the BBC for avoiding the phrase "dark matter." I was just complaining yesterday that "dark matter" is the headline of every mystery of physics. Ghosts makes me stop and scratch my head.
I'm glad I wasn't the only one confused by those headlines; it took me a while to figure out what "ghost particles" was referring to.
"it's not super expensive, only one-hudred-million" Sabine's sponsorships be PAYIN'! :P
Relax, I work for SHiP and we barely get any money. This experiment has a developement + running time of roughly 30 years. 100.000.000 is not a lot, trust me.
@@MicroageHD I am relaxed lol I'm just making a joke about her saying 100 mil isn't expensive lol yes, i know comparatively to other experiments that cost billions, it's cheap, but that comparison wasn't explicitly mentioned which makes it funny. relax :D i'm not trying to say SHiP is a waste or not worth it or trying to call anyone out. it simply sounds funny to say, out of context, "100 mil isn't much" take note of the 'tongue sticking out face' emoji in my original comment.
Good. nicely explained.
I saw a video talking about "rogue" planets that are wondering around the galaxy (and presumably all galaxies). It was postulated that there are a lot more of these "dark" planets out there then we thought and this could even be the source of dark matter. the idea was that if there were enough planets without stars to orbit around, they would be very dark and hard/impossible to detect, but would add up to a large gravitational force. did you ever think of doing a video on this idea? thanks Sabine for all the hard work on your videos. i really enjoy them.
Not that it isn’t possible, but there would have to be an absurd number of them to be the entire cause of dark matter.
Stars are just so massive compared to planets, if dark matter is 80% of all mass in galaxies can you imagine how many planets it would represent?
The point with dark matter is that what we observe is that it has a gravitational effect, but it doesn't interact with electromagnetism or weak and strong nuclear. If there were just many planets that we can't see, we indeed would see these gravitational effects, but we would also see more effects appart from gravity. That is all the point with dark matter and its difference with normal matter, it is not just normal matter that is in a dark place.
I found the particle responsible for dark matter but I lost it at home. My mother always tells me "you're always losing those damm particles and I must find them later!!"
Why do you think it's a particle? Astrophysicists call dark matter an "observable effect for which a cause has not yet been found." It's effect is easily seen. What causes it is unknown.
“Poke and Hope”… works as a strategy playing pool and now it’s applied to Physics…good luck. Experimentalists are easy! heehee…
you get neutrinos from your bananas too! oh no! :)
And an electron and daughter calcium-40!
I'd certainly consider 100 million euros expensive, but particle physics operates on a different scale these days.
As a stiens gate fan i cannot allow CERN to mess with dark particles 😂
Calling them "ghosts" is a literal zeitgeist.
You literally do not know what the word means.
Brilliant, nice experiment....
Ah, next to Bosons and Fermions we will finally have Casperons.
The hardest thing in the universe to find is something that does not exist. as far as i know, a Nothing Detector has yet to be invented.
They should have called it SHiT: Stubborn Hunt for Imaginative Theories.
😂 so true
Dark matter of the gaps.
that was sabine dancing around in a ghost costume 🤣
That might be, she moves very nice in her music videos
I always believed that apparitions are real. Physicists will soon find out.
I thought a part of the SPS was demolished and the remaining part is a pre-collider to the LHC? Cool if they reactivate it.
To misquote "Field of Dreams," "Build it and the particles will come!" 🤪
The Scooby-Doo gang should poke around CERN. See if they can catch a guy in a mask.
Ghost? Ship? Is the CERN now looking for the Flying Dutchman?
There is of course hidden machinery: its an outgrowth of mirror symmetry.
We can forget that brains can have a sense of humor. Thanks Sabine...
All that build up for something so short and sweet, 😆 i don't envy having to make videos like Sabine does 👍👍
What I don't get is how a massive particle is less interactive than a neutrino? isn't the dark matter neutral and more massive? how is that something similar but way bigger is less interactive?
That is what they thought in the past, what i understood is that the theory shifted to defend that hipotetical dark matter particles are actually less massive. There is also the opposing theory, modified gravity, that doesn't need new particles.
Dark matter, the Easter bunny, string theory, Bigfoot and UFOs...
Who you gonna call…? Ghostbusters!
Thanks, Sabine! 😊 I've heard ghosts are good people. Or were, I'm not sure. Anyway, stay safe there with your family! 🖖😊
"It's not- It's not shutting down!"
The fact that there isn't an eye-watering price-tag attached to this experiment makes me a lot less cynical about this than I usually am about particle-physics experiments.
Could regions of reinforcement from overlapping gravitational waves explain what we observe as 'dark matter'?
what is the frequency of a particle that has a wavelength of the universe? and is such a thing really observable?
They gonna love them hidden particles, this is exciting
I was wondering about the possibility that we might have missed something rarely produced or hard to detect in an energy range lower than the maximum of our particle accelerators, and had been thinking to ask it in the comments to some future Fermilab video . . . and here it is, under actual consideration.
Who ya gonna call? CERN!
Lol, I used to work at CERN with the CHORUS collaboration experiment, looking for neutrino oscillations out of the same tungsten target. I bet this is at the same experimental location. Ironically the neutrino oscillations couldn't be detected at CERN because we were too close to the source of neutrinos...
Scientist opens door and looks in the closet for hidden particles, "Peek a boo."
Sabine is a Ghostbuster now
Sounds as if Star Trek's Transporter could become a scientific reality someday.
How many ghost particles in the average ghost?
😅one should ask the ghostbusters
the experiments have been done. the papers written. the results ignored for more costly endeavors. good job.
Thank you for your insights. Maybe it has more explanatory power to assume that the particles also go through the superfluid phase transition that you were working on? (name it superghosts)
Yes, the masses of particles that can form superfluids are in the same range. I've actually spent quite some time trying to come up with estimates for direct detection experiments, but in the end I couldn't find a way to say anything sensible about it. (So I said nothing...)
@@SabineHossenfelderThank you
. . . and I suppose that SHiT stands for "Search for HIdden Things"
Shoutout to whoever have to machine those Tungsten to spec
Try looking for temporal particles. We seem to forget that time bends as well as space. 🖖😎👍
Your videos are more interesting, fun and easy to understand than videos from PBS Spacetime.
SPS operates at 450 GeV, not at 5 GeV like Sabine said.
Tungsten is prone to corrosion. Tantalum cladding fixes that.
Well one thing is certain. I ain't afraid of no ghost and neither does CERN!😁
Sabine let her inner Texan out for a moment.
Let's talk about the ectoplasm field.
Sabine, you could write an excellent guide to writing science articles! It would be great to read about Karl Popper and falsification, how to write about science without writing oversimplified bulls*t that "isn't even wrong," to borrow one of my favorite critiques of bad arguments. I was fully expecting you to call bullsh*t at first, just on the basis of the headline of the BBC article, so it was interesting to discover what a reasonable experiment it really is and WHY it's a good one, and to realize it was merely the BBC that was full of it. So much bad science writing in the world!You're a gem amongst so much drek.
2:23 _Tantalium_ - perhaps we should regularise the name to fit in with Aluminium.
If there are no 'ship ghosts' then where does Captain Jack Sparrow come into the equation? 😊 And they say physicsts have no sense of humour
Maybe it's an excuse to fire those big, powerful things more often - that's got to be a lot of fun.
There’s actually an employee named “particles” who works at CERN. He hides everyday and they look for him.
The why files is the most honest debunction channal
Why isn’t this all over the news like what
If it keeps the particle physicists out of trouble, I’m for it.
What if dark matter is the fabric of the universe, the quantum foam, or the ether, or whatever you want to call it? Fabric bunches and if more is gathered in a spot we would expect to see stars gathering more in these gathered folds, you know like that supercluster.
The fact you didn't flash a quick reference to ghostbusters movie of some kind makes me sad :)
What conversation tidbits would hold your attention on a first date Sabine?
Wie lange kann man dieses Publikationstempo durchziehen?
My ghost is getting ptsd before im ready
They're calling them ghosts to catch people's attention. I think it's a good idea.
To a hammer everything is a nail to a physicist everything is a particle
For particle physicists. For astrophysicists everything is a star: main sequence stars, neutron stars, white dwarf stars, red giant stars, black stars (now called black holes), star nurseries, star clusters, binary stars, etc.
Someone behind the project needs to find a way to get the device officially designated the PKE. They are already using positron coliders (though sadly, while probably for the best, this one is licensed)...
Remembering a time when saying "low energy" about a 5 GeV accerator would have gotten you laughed at....
Found a ton in my Belly Button
The "It is dark matter" is like "It must be Aliens!"
"If we assume gravitational interaction with a dark matter halo..." "Why do you always blame it on dark matter?" "Because if I blame it on elves they'll cancel my funding. Do you have a better suggestion?"
No not really.
They should look into old lighthouses👻
Im not a scientist but I have videos recorder with nvg where light, energy orbs clearly go thru objects. Also they react to laser and will approach to interact if they choose to. I only see them in one area . Tried in other cities and I didn't see any. Are these ghost particles?
I always felt like camera film cases could possibly contain the secrets to dark matter. 🧐
We love Sabine ❤❤❤ but, my gal asks: do you have only one shirt? Every time she looks at the screen you have the same shirt on just about. For the sake of my ear, please bring in changes for when you shot sets. :-) ... see i cant even get through this response without her adding: its a nice shirt, but variety is the spice of life, girl! Have fun with it!
She explained it already som e other commenters: it´s because of the sponsors
🤔 I can already imagine how they will modify that acronym if the experiment fails... 😂
Hess particle accelerator is always two steps in front of cern
