Inside neutron stars we can find the weirdest and most dangerous substance in the universe: Strange matter. What is strange matter, how dangerous is it and what can it tell us about the origin of the universe?

  • This comment section is full of memers

  • Cannotreadth Engsub :/

  • So you're telling me they didn't name it a hulk quark and hulk atom

  • I'd like to start measuring various things in "strangelets".

  • What if a strangelet collided with a stable Higgs field

  • its like ice 9 in kurt vonneguts book cats cradle

  • So basically; it’s a virus.

  • Are you the narrator from hitchhikers guide to the galaxy? Lol

  • Wait, so how is the star holding against the strange matter?

  • Magyar feliratot please :DDD

  • you're getting more awesome every time you posted a new video. can't thank you enough.

  • (´;д;`)

    • 日本語の字幕がない(`;ω;´)

  • Kurzgesagt- we can destroy the universe with a jelly bean ___3_days_later___ NEW FLASH: Riots in jellybean factorys all over the wold!

  • You're as dense as a neutron star!

  • New idea for weapon of mass destruction: Strange bomb. Basically imagine Third Impact from Evangelion.

  • why don't have vietsub ? plz send it I want to know how is neutron star ?? plz

  • Pls tell me how to pronounce yr channel name....very informative vidoes

  • Hagan también su canal en español

  • If strange matter can infect other stars, how our universe could be born? Should we receive the signal of energy released when a star is being infected if this theory is true?

  • is it possible that we already infected by strange matter

  • Omg! I just have to say this I love the adorable little Birds you use in these videos! I just wanna hug them they are just so dang cute. Also I loved the video!

  • *naming quarks be like* Duck: I have an idea Durck: I have a better idea

  • anybody find this in their music playlist

  • Nobody: Comment section: "hey ill comment "Nobody: " and "am i a joke to you" to get likes because it works in other video and im sure fools will surely like it because they are fools" EDIT: OMG Thank you for 1 like!

  • Why was this in my music list?

  • isnt that disobeying one of the laws which says "infomation cannot be destoryed" you said strange matter converts matter into strange matter, similar to blackholes in another video?

  • Good video dear

  • Kurtzesagt- Strange matter maybe the strongest most indestructible matter in the universe Me-Have you ever heard of flex tape?

  • Life: exists Kurzagesagt: this is some gourme sh**.

  • I love this channel. I mean, you do a f*** great job, super cool animations, simple and real information, but how do you earn money? Only by the ads? :v

  • Nobody: Not a single soul: Kurzgesagt: make a depressing video and add some birds

  • So instead of the planet ending in grey goo the entire universe could end in strange goo. Great :X

  • Scp 9999 Object class: apollyon

  • I'm happy the camera man is alive.

  • whats wrong with everything going green and small?

  • I just love how we know all this stuff about deep space without ever being their.

  • hmm this is strange.....

  • It would make a cool movie

  • This is how to destroy the universe: throw a strangelet at the universe

  • It converts anything it touches, yet is contained within a star?

  • Basically we can get 360 noscoped from space by gamma ray bursts or strange matter,where’s the panic button?

  • Here's a question. If strange quarks decay, why are they stable?

  • Wait could we still live in a body made up of srange matter?

  • The arabic translate plz


  • So what you are saying is if I get hit by strange matter I turn into The Hulk?

  • I was high when I whatched it, pure gold...

  • One can only dream

  • Im defying the laws of physics im doing a split as a boy but it hurted very much

  • I appreciate you very much and wish you continued success.

  • You should do is teleportation possible

  • What doesn't turn you into a black hole simply makes you _stranger_

  • *-strange matter is very strange-*

  • 0:01 that's wrong, pretty sure i'm denser lmao

  • This was in my mix. ??

  • Do essential oils really work? If yes then how?

  • me: today sucked -new kurzgesagt video appears- me: nevermind!

  • This is probably the best way to die that they have made a video about

  • Can we get another video about the other quarks shown in the video

  • soo.. infinity stones?

  • If stange matter transforms all matter it comes in contact with into strange matter and is very common in the universe, wouldn't it have turned the whole universe into strange matter already? Given how long the universe exists and the fact that strange matter would grow exponentially.

  • Coolest animated stuff!! But I don't think anyone can overpower *kurzgesagt* in it's content too !! AMAZING !!

  • this channel teaches me science better than my school does

  • Humans: Humans are so strange and dangerous that they're going to make us go extinct! Universe: *hold my beer.*

  • if strange matter turns regular matter into strange matter, wouldn't that apply to the outer layers of a neutron star too? so if there's strange matter in a neutron star, sooner or later the whole neutron star would be strange matter.

  • I normally love your videos but to be honest this hardly explained anything, why is it so stable?

  • 4:26 Did you seriously fucking killed two innocent birds just to make this video? dislike

  • Maybe we were already infected with strange matter

  • and here things get STRANGE btw, i mean this comment section

  • the ducks are back!!!

  • What's wrong with being strange matter? If everything in the universe is strange matter won't it be ok to be better for us to be indestructible?

  • Kylie jenner: *is that a chicken* me: errrr close enough

  • for 4.6 billion yrs nothing happened to earth kurzgesagt: makes this video me:who gives two fucks we were safe for 4.6 billion yrs

  • Can you make a video about how survival instinct evolved and why we even need to survive?

  • hmm very strange

  • I really want to know, if you do this for views or to teach interested people like me. ;-)

  • Obrigado por legendar seus vídeos, principalmente em português.

  • why is this in my music playlist

  • Weird Cartoon Channel But Ok

  • What if we already are strange matter¿

  • Especially this video. ☺

  • Wow you know I like kurzgesagt

  • Hey kurzgesagt, i have a bideo reccommendation. Can you talk about the Bose-Einstein Condensate State?

  • Just remember the dogma kurzgesagt: Time >> Quality & Love (don't end up like "The Infog**phics sh$t")

  • Just remember the dogma kurzgesagt: Time >> Quality & Love (don't end up like "The Infog**phics sh$t")


  • In the near future, scientists will prove this video was very accurate. Or maybe not.

  • If you’re interested in space I highly recommend downloading Space Engine. It’s super mind blowing

  • If the stranger quarks are unstable, how stranger matter can be stable?

  • I like how this guy could be saying complete bull and we would still be fascinsted by it

  • Kurzgesagt: the Big Bang} me: OO that’s naughty to hear that from u

  • Kurzgesagt - Terrorism in a Nutshell

  • I just care the new intro only

  • Why do you assume that strange matter is so very stable, when everything we made and looked at that is vaguely similar should and did decay very fast? You even say everything but up and down quarks are unstable. Sure in a neutron star, strange things may happen, but as soon as pressure is released, what tells us that that strange matter doesn't just decay?

  • Would the world be better if humans wouldnt exist?

  • Out of curiosity, how would strange matter interact with antimatter?

  • Strange matter is the cancer of universe

  • Meantioning the simplification. Good.

  • Always likes before watching :)
