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?

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.

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?

Thanks, Contingence! It's definitely a group effort!

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 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

​@@kiloperson5680Shut up

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.

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.

That's a total cliffhanger

Hhhhhh omg me too

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

Thanks, Madcat789!

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

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?

no wonder that sounded to familiar!

Michael here!

Thanks, Pink Ribbon! We're so glad you enjoy these videos and find them useful for your education!

The outrageously talented entities from Lazy Chief. Possibly extraterrestrial, but there's no way to know for sure.

Thank you, Diamond! Your support and kind words mean so much to us.

That's what I thought when I click it.

DrakerGaming I like that they uploaded this 4 minutes ago and this video is 5+ minutes long

chal nikal

that was about antimatter

And the people who produced all the knowledge you see in this video learned more in school than on KZfaq.

@@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.

same to you

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”.

ScienceAIR will do that..... and btw im nepali

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.

That's wonderful, Jane. Thank you for watching!

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

Go away, go back to kitchen nightmares

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

Dark echo, not dark matter.

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"

why?
