Eighty-five percent of the matter in our universe is dark matter. We don’t know what dark matter is made of, and we’ve yet to directly observe it, but scientists theorize that we may actually be able to create it in the Large Hadron Collider, the most powerful particle collider in the world. So how would that work? CERN scientist Rolf Landua explains how to discover a new particle.

TED-Ed your other video says 25% is dark matter hmmm
+Holy Ghost, about 85% mass of a galaxy is dark matter
About 68% of the universe has dark energy, 27% dark matter and 5% regular matter
Είσαι Έλληνας;
No, you can't create dark matter...you can concentrate it though! Just put two plates of metal microns away from each other. To all physicists or historical analysists of youtube, excite this comment section with my obvious theorem.
Why can't you monetize the videos?
I lost it when you showed ducks as Quarks and glue as Gluons. So it's more like Duck Matter!
Riju Chaudhuri quack matters
Duck Dodgers more elusive cousin.

Ted Ed is non profit but most vids are so easy to understand and seem to teach me more than some school teachers can in a year.
ATOM If you learned more from a video than from a year of school you probably have a learning disability and need to see your doctor to get accommodations.
Thomas Stewart
It's just an exaggeration of how much easier the video is to understand than some teachers lol chill
People keeps saying this but as soon as channels go in depth like you do in school (the boring parts) then people would complain how the video is boring. People like to watch videos to feel smart but really its just fun bits of information that you can answer in trivia but nothing you can really apply in the future.
teacher are foolish
That is completly true.
As an astrophysicist, I absolutely love the graphics!! Well done!
Wow, thanks Rachel! That's great to hear!
I think the graphics are good to.
I want to be an astrophysicist when I grow up
May Alllah(SWT) guide you to the truth.
What's a astrophysicist? Also can you tell me how am I gonna be a astronomer?
The animation in this lesson is fantastic; shout-out to Lazy Chief, CERN, that guy in the U.K., and the collective Ted.
Thanks, Contingence! It's definitely a group effort!
Who else understood the ending with the tortoises
Aaron Muller Stephen King?
Aaron Muller that Bertrand Russell story right?
isn't it a reference to discworld?
i first read it in brief history of time by Stephen hawking
Aaron Muller what is it about?
I love that science has reached a point where it's so insane their only option is to stare at numbers until a little bump tells them they've found a new aspect of nature.
I love your angle tho. Science used to be about explaining just the stuff around us and the stuff that we encounter on experimenting, but all we are looking for now in the smooth CONCEALED world is a bump.
Shut up

"What's the matter Dark Matter?"
"Nothing much, apparently."
Power beyond your wildest dream!
This was one of the best teded video's i've ever seen, loved the animations and the subject, I love you guys!!!
Thanks, Thibo!
If we don't even know what dark matter is, how will we know if we've produced it?
Feynstein 100 i see you basically on every video

If it's a particle, we know it has to be massive and neutrally charged
Feynstein 100 if we don't know how electricity works, how will we know when Ben Franklin gets electrocuted?
The LHC has likely already produced dark matter, though we can't directly detect it. The key is to look for "missing" momentum. When a particle decays, the products must have the same total momentum as the original particle. However, we've observed some events where two known particles are emitted in one direction, while in the other, you get... nothing.
This is either a particle or set of particles that the detectors can't detect (a form of dark matter), or confirmation that the most fundamental principles of physics are wrong. The dark matter outcome is far more likely, since finding that momentum isn't conserved means that the laws of physics are different in different parts of the universe. The really interesting thing about this is that this production of dark matter particles means that they participate (however weakly) in one or more of the fundamental interactions (electromagnetism, the strong nuclear force, or the weak nuclear force) that they aren't 'supposed' to. Gravity doesn't participate in particle decays.
Fun fact: this is actually how neutrinos were discovered. Scientists noticed that muons decaying into electrons followed paths that were mostly straight, but bent at right angles at specific points. That missing momentum was carried off by a neutrino.
Ted Ed should make a new channel for kids to explain scientific building blocks so they can better begin to understand these videos
there are already some great channels, though. I enjoy Crash Course and PBS Space Time.
James Stephenson i suggest salmonella 😨! I MEAN SAM O' NELLA😅😅😂
Ramieverse ! Well Sam O' Nella isn't really for kids
waylon sherman hmmm yeah, your right
James Stephenson Watch SciShow Kids or Crash Course Kids.
4:25 My whole live was a lie
That's a total cliffhanger

Hhhhhh omg me too
The universe is on the top of a stack of turtles?
Unoriginal Commenter Yes, how come you didn't saw that
Unoriginal Commenter Yup, it's turtles all the way down!
weird. I thought the universe was on a turtle swimming through an ocean of milk...
surrounded by a snake...
+oriana garrido that's just the turtles turd
I like turtles
I'll support your Patreon. You guys do good work.

Rick and Morty!
One of the best animations TED Ed has ever created. Great work guys!
Can't you just ask Rick?
Kehan Vora yeah ,he will explain in seconds
ok cool
dude, you have to triple scam him, like the Zigerions
Well considering how they ended up, that would be a very bad idea, you'd be better off yelling through a megaphone on an island full of dinosours
Robert Adonias Costa Gomes I doubt anyone of us can!
Damnn.. 5 months for a 5 minute video.?!
At 4:30 WORLD OF GOO TOO (2) REFERENCE.
Yeah, 3 years for a 1 hour movie.
Sanjay Vasnani animation is a long process
No, Five months for making you understand 'could we create dark matter' in a quirky and unconventional way, though a video, consisting animation and sound only.
What about you? Can you animate 5 minutes in less than a day?
you people are amazing , so creative so artsy yet easy to understand and to remember with these talented animator , great script edits and last and not least the voice just feels like talking to you about something so complicated yet here you guys make it look easy
This my favorite style of animation from them. So unique for them and portraying the concept in realistic animation while explaining one of the most abstract concepts is genius 🥰
Feel Lucky to be living in the time when such amazing knowledge is available for free and most importantly put together in the most comprehensive, graphic way possible!! Thank you #Ted-Ed. My free time is all yours!
"As always, thanks for watching"
- Vsauce
no wonder that sounded to familiar!
- Game/Film Theory
Michael here!
thank you for working so hard on these videos we really really appreciate it
These sound effects are amazing, they go with the graphics so well!
Thank you so much for the content, seriously. It's mad this stuff is not taught in schools yet
شكرا لكم على ابداعكم وتميزكم
thanks a lot for your Creativity
This video had some of the best animation, dialogue, and sense of humor that I've seen in an educational video. Keep it up; we love to learn from you guys!
This is a very easy to understand description. Thanks!
thank you ted ed for all the videos, you taught me so much my teacher could have never done, without you i would never know about so much stuff thank you so much you have no idea how much you helped me out like the entropy video i never understand why things work like that THANK YOU TED ED
Thanks, Pink Ribbon! We're so glad you enjoy these videos and find them useful for your education!
What kind of godlike entity from outer space animated this shit?
The outrageously talented entities from Lazy Chief. Possibly extraterrestrial, but there's no way to know for sure.
The animations are so good and it is so clear to understand
The animation in this video is just amazing , so pleasing to watch...
Thanks for the video!
I can only pledge $1/month on Patreon for now as the bills are endless but thanks for another awesome vid TED Ed. Always loving the animation, narration, and information. Hope you guys reach your funding goals! 😊
Thank you, Diamond! Your support and kind words mean so much to us.
I already have dark matter on bo3
That's what I thought when I click it.
Silent An
family girl no
thank you so much for your beautiful collaboration and work TEDEd. God bless you. we've learned so much here.
I really enjoy the way this channel explains everything. It's normally so easy to follow.
cac
Pretty explained. Great!
DrakerGaming I like that they uploaded this 4 minutes ago and this video is 5+ minutes long
Dark matter is like a common material that was plentiful a long time ago... And now we want to use it.
Flying cars and space travel might be closer than we think!
I always wonder how Ted ed team make this many videos, which is so brilliant. But five months of work.. I didn't expect they are putting that much time and effort. Now it explains the all the cool animations and scripts and so on. I couldn't access to the site on my phone last time, I should try on laptop again. Thanks soooooooo much!
I greatly thank you for the hard work and the effort to teach us about so many topics. Thank you Ted Ed Team!
Thanks for your videos Ted-Ed ❤❤❤
chal nikal
Great animation
Thanks for the amazing work on videos like these which let me know more and continue to feel admiration for people who contribute significantly to education and science.
Your animation is always spot on!!
"Angels and demons" by Dan Brown. That is all I could think about
that was about antimatter
Yep, I learn more on RUclips than in school
And the people who produced all the knowledge you see in this video learned more in school than on RUclips.
@@theultimatereductionist7592 That's the power of technology, the same knowledge that required years of education can now be fitted in a ~6 minute video.
I wonder how much more information will we able to put into a video that is under 10 minutes in the next 50 years.
I appreciate your work and thank to all the people help prepare this vid.
Wow this video was on totally another level I understood everything easily, especially the animation was top notch
I thought it said "Could we *break* dark matter?". I realized my mistake after three whole minutes. Why do I have to misread words all the time.
If Dr. Wells can make it, then we can too!! lol
That's one of the best animations I've ever seen, great work!
The animations are so creative, I love it!
It should be called Dark Gravity.
1:59 thx for the seizure, 10/10 would almost die again
I seriously love the animations for this video
You guys are the reason why I'm learning so much.
Thank you for inspiring me to create my own channel.
Love u ted ed.....
same to you
These videos are amazing well done I appreciate your work
One of the best animation in TEDed!! Lazychief did an awesome job
Please make some more ted ed riddles. Like if you agree.
But if DM is so unstable it instantly decays how come there is so much of it in the universe? And given that it doesn't seem to interact with anything but light won't it just fall through the detector and be, well, undetected? LHC was built by people a lot smarter than me and I am sure these questions have good answers but it would be nice if a new vid or maybe someone here answers them.
1. I think you are right, it can't decay quickly. The Higgs does, but dark matter just can't for that reason.
2. They'd find it by noticing missing momentum. That's not so different from how they found the Higgs, which decays too quickly to measure. Instead of counting up photons of energy x, they'd have to count events that had missing momentum and plot that. I guess it would show up as a bump on such a graph.
Thank you, and it is a good point. Detecting its absence is almost as good as detecting it. If mass-energy just disappeared it is a good bet it was dark matter.
If you take into account that, as much observable matter is in the universe, it is mostly just “empty”. So, maybe the dark matter is harder to detect here on earth because there are so many ways it can be interfered with by other matter, as opposed to just a bunch of it floating around in deep space, light years away from any “regular matter”.
I didn't know it takes soo much hard work to make a ted Ed video. You guys are doing a great job. Thank you for teaching us the things that we couldn't have exposed to.
Amazing art work! You guys always put a smile on my learning face! :)
I thought it said: "could we eat dark matter" so I was confused.
Ted ed tryna be like vsauce. "As always thanks for watching"
TED-Ed videos are the best! :) Thanks for making them!
I love the videos.They are so informational.
I love ur channel so much.
I swear to u... if i start earning... im helping!!! 🤓🤓
ScienceAIR will do that..... and btw im nepali
Also, 75% of the universe consists of dark energy, not dark matter, which consists about 24%, if I recall correctly. But I guess it doesn't really matter because we have no idea what either is anyway.
He talking about all the matter not the total energy in the universe
According to the standard model of cosmology there are 4.9% baryonic matter, 68%Dark Energy and 26.8% of non-baryonic Matter broadly and largely draped around and between the galaxies, without emitting or interacting with electromagnetic radiation, but interacting with gravity, so you cannot see it. It’s why it is called dark matter (DM). You can found that ratio from the fluctuation of CMB!
They're the same thing! In the world of particle physics, matter and energy are interchangeable.
Thank Einstein for that one.
Feynstein 100
Truly appreciate for the Ted's efforts for sharing knowledge through RUclips channel. It stimulates my interest towards physics.🙏
That's wonderful, Jane. Thank you for watching!
Thank you for the presentation
RUclips says 1 comment. I see 9. RUclips's drunk again.
iT SAYS 5 FOR ME AND THERE ARE EASILY 20
INDIGO BLUEoO RUclips says 31 comments, I didn't bother to count (lol)
INDIGO BLUEoO
youtube go drunk you're home
RUclips don't lie, you're drunk again.
INDIGO BLUEoO Are you bloody new mate?
Who else lives for Ted-ed videos?
Me
I want to know science more, but im easily bored
Muhammad Farhan samee
+Sara Sihvo I guess science isn't our strong suite, even though science is needed.
Meee
Thank you for your great work TED-Ed, first time I became a patron
As an LHC and user and someone who works on dark matter detectors I have to say this is one of the best videos I've seen explaining, in simple terms, how the LHC goes about finding new particles.
just turn off the light from the matter
what's a matter you ask?
I don't know, what's a matter with you?
PUNS
off to make a patreon bye!!..../
Thank you so much!
Congrats on the graphics. This video was awesome!
lovely animation work as always
#turtlesoftime I know dat reference (tasty planet)
Nom
The right question is: SHOULD WE?
you never know which advancement will explain fermi's paradox ;p
by killing us all
Mahoole Magic School The answer to that Question is - What then?
We can't sit there just waiting if the aliens will come to us (very vague) willingly and threatened to kill us so that we can dab then - we try to understand the thing that we were born into due to some weird chemical reactions in the very past (life) and then natural selection and evolution coz we're bored not to experiment with things that we surely can just like a 5 year old child and that's why we do them
Chaitanya Singh I blew on my screen because ur profile pic 😂
Dark matter is all around us. If it was deadly we would already be dead. Particle collisions of much higher magnitudes happen all the time in earth's atmosphere, so we aren't doing anything nature doesn't already do billions of times more often than we do.
U worried the lhc gonna open the portal to cthulhu?
Mahoole Magic School adding dark matter does not react with ordinary matter so you may be really fine if aliens made of dark matter try to invade us coz then they can't
BORING
I love ted-ed so much. I wish I could watch it all day everyday.
Thank you ted ed i realised i took you for granted way too much
Does it matter?
*Dank matter
Outstanding animation! Good job Lazy Chief!
OMG I never realised this much of work goes into creating a 5 minute video. Hats off to everyone involved
Nino can cook dark matter.
Go away, go back to kitchen nightmares
5 months of work?! Like 1 minute per month? 2secs per day? Did you draw every single frame by hand?
Glad U the research takes a long time, and so do the animations and editing. I would imagine that the research would take around 1-2 months, the animation 2-3 months, the editing and narrating about 1 month.
Jonathan Z you must be kidding. A master thesis with 80 sites takes 4 months of not too much work. Animations can be done pretty fast too. I bet you can research all of this and create animations within a week even if you barely work on it, especially when you're familiar with the corresponding subject (what a cern scientist and an animator for sure are )
Glad U the ted ed animators, narrators, and editors probably have lives outside of ted ed. That is probably why they take a long time to make.
Glad U if ur so smart at estimating the times, why dont u try. Remember no profit from ur vids, a bunch of ppl who hsve outside lives 5 of animations to the frame. Oh, you cant. Mhm
Amazing! Thank you. Always wondered how the LHC worked.
Thank you wonderful people from around the world who make these amazing Ted-Ed videos 😄 Y'all are incredible! 🙏🏽 These vids are some of my favourite forms of edutainment ❤
Isnt dark matter like that stuff from jake and dexter
Dark echo, not dark matter.
4chans gonna harness dank matter to make memes
Thank you for your job guys!!! You really make this world better and smarter!
Great animation and explanation, thanks !
Your channel says that there is 85% dark matter out there in the universe and other says that there is 70% dark energy, 25% dark matter and only 5% is matter. Don't know who is correct either you guys or they.
Let me explain it to you. Dark matter makes up 85% of the MATTER in the universe, but dark energy is exactly that - energy, not matter. Dark matter is so dense it has less than 20% of the volume of the universe. However because of its density makes up 85% of the matter. I hope you understand now.
nobody knows. 85% is an estimate, because we don't actually know what dark matter is nor can we measure it. dark matter is a place holder name for "energy in the universe than we don't know the origins of nor do we know how the universe works"
I'm early (first comment) (this only got 49 views)
why?
What an amazing animation! Love every second :)
Great animation guys! I loved your video. Soon I will be becoming a patron of yours!
