Could we create dark matter? - Rolf Landua 

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

Why can't you monetize the videos?

Yet you didn't.

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.

Guys please dont forget to share and donate

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?

Power beyond your wildest dream!

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.

That's a total cliffhanger

Hhhhhh omg me too

Denial Number Four *quartz

Rick and Morty!

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

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!

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

no wonder that sounded to familiar!

Michael here!

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

@@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.

cac

That's what I thought when I click it.

Silent An

family girl no

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

LOLLL (also yeah for those who don’t get it)

same to you

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

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

Ted Ed quietly leaves some "insider jokes" and references in their videos to make it worthwhile for the professionals in their fields to watch it :)

Thank you so much!

Thank you, Arman!

Go away, go back to kitchen nightmares

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"

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
