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?

  • The most dangerous stuff in the universe? An idiot with a platform to reach millions.

  • You know what strange matter looks like? That’s right, the portals from rick and morty. Rick is slinging strange matter across dimensions

  • If a neutron stars is as the early universe was, wouldn't strangelets have been present from the beginning?

  • Why are black holes the answer to all of our universes problems?

  • Please... Indonesian subtitle

  • Please... Indonesian subtitle

  • My penis is one of them

  • single atom of strangelet hit a human, poof Zombie Apocalypse

  • @kurzgesagt tried to put donald trump as a bird at 5:52 ,the red one in this video😂😂

  • If this strange matter already exists inside a neutron star and has properties which changes matter I don't understand why there exists a neutron star instead of only strange stars. Wouldn't the strange matter convert regular neutron star matter into strange matter?

  • Do you believe in god?

  • Strange Matter: Normal Matter: wow you're so cool I wanna be just like you

  • Are these theory's

  • Well, I for one am excited for the heat death of the universe to instead be a zombie like plague of strange matter infecting everything and forming some kind of stable state universe.

  • what the fuck

  • If I understand correctly, though ("if" being the operative word here, as I haven't studied this in detail), strange quarks eventually decay to up quarks and W bosons. So wouldn't strangelets eventually just decay into stable hadrons over time? Or are they so "stable" that even the strange quark component is unable to decay?


  • SCP-XXXX class: apollyon Description: strange bEan

  • I guess you could say there are 2k _strange_ people out there

  • That sounds like a sci-fi horror story. Also Brilliant is too expensive.

  • Man science really reads like a bad fanfiction sometimes.

  • Dude, imagine if there was a god-like civilization controlling our universe and black holes are just things made by them to ‘dispose’ of any strange matter out there to prevent it from contaminating everything...

  • Does this mean our universe could be in a neutron star?

  • Fuckin wierdos

  • Except that almost all evidence points to strange matter not existing. If it did, strange stars would be almost the rule for neutron stars, not the exception.

  • Mate I just wanna live till I'm 90 and I'm good

  • this was on my mix tape for some reason... why would youtube thing this is a song.

  • Dark matter, Anti matter, Exotic matter, and now strange matter?

  • Strange quarks decay into up and down quarks we are safe

  • The little bird scream at 7:12 !!! It's so cute!

  • If strange matter is so perfect then wouldnt letting it infect everything bring the universe to peace? 🤔 Im down, come here

  • Who else misses the human animation over the bird animations? No hate whatsoever. This videos always blow me away.

  • *thanks personal mix playlist*

  • How to make an edgy teen want to go to space

  • F*ck we just found the creeper from creeper world series

  • This was not the source of human destruction I was expecting.

  • Thanks yt for puts this video in raccomanded This is pure gold

  • I think Kurzgesagt made it their life goal to make us as miserable as possible before dying.

  • What happens if a strangelet hit a human?

  • Strange matter is dangerous for our comrades. We have to do a small deportation (of strange matter) to Siberia.

  • So what I am hearing is that strangelets make for excellent exterminatus weapons.

  • So.... is this how the zombie apocalypse would appear from?😂

  • Please say sike...

  • “Neutron stars the the densest things that are not black holes.” I dunno, I know some people who are pretty dense

  • Like Phazon!

  • I'd like to suggest a video topic: Bose-Einsteinium condensate

  • A new way to destroy the universe! Wonderful!

  • yay realitybending

  • So strangers are people who got hit by a stranglet?

  • Thanks again for existential dread Kursgezagt!

  • Video: Appears in my Music playlist because I removed a video from it. Strange Bean Matter: 6:18

  • Wow! I am surprised that you found a topic on astrophysics and nuclear physics that i never hesrd before!!! I knew the video was good even before i watched it but now i am even more amazed! Thank you little birds! Thank you very much!

  • Emus?

  • If this COULD happen, it likely already would have...

  • Strange Matter: -Can't infect things -Part of hypertheorethical Quark Stars -Being Part of an Quark Star is absolutely amazing Plz make an Video about Quark Stars ;-;

  • In german: Seltsame materie

  • Phazon

  • Hi. Oh sorry for my bad english ;))))))))))))))))))))))))))))))))))))))))

  • yeah you REALLY simplified it ! it's not a problem but , yeah ...

  • Kursdezagt: The scientists thinking about the cause of neutron stars and strange matter today may be setting up humans for a future beyond our wildest imaginations. Or, maybe not. Time will tell. Me: I CAN'T WAIT 100 YEARS!

  • It would be interesting if you do a video abought the first picture of a black hole.

  • Creeper Quark

  • can you make a video on how canned food is the most ecological thing in your local supermarket ?

  • Fuck u

  • Cute birds.. I love your style

  • Succ peen

  • Isn’t it wrong to say something “bends the rules of the universe” ? The laws of the universe are never broken, we just don’t understand what all the laws are yet?

  • I love the pop culture references in these videos

  • Kurzgesagt, when clickbait actually delivers

  • I would be really interested in a video on autism and its function!

  • You said quarks cannot be separated . Then how can they saperate in a neutron star

  • The star looks cool

  • If strange matter is stable, then why do strange quarks decay?

  • I know a channelb that's a lie. It's IMPOSSIBLE for a LOT of comments to ask for the same thing unless they have this group that posts all these comments to overtake the other comments! The channel name is [literally] called, " awesome gameplays."

    • Kinda like how Facebook got popular because they stole videos from CS-tv

  • in just 5 days almost 3 mil views dam

  • Arabic subtitle pleeeeeeaaaaaaaaseeee

  • That was brilliant.. thank you!!!?

  • And...If all this is wrong?

  • Где русские субтитры????

  • I like how the one bird that pops its head out of the snow saying "Didn't see that coming"... Looks ironically like Donald Trump. Lol

  • I love this

  • Almost 4 million views in 4 days. Jesus.

  • This video is indeed very ‘strange’ I’m not sorry

  • *whispers* hey..dont tell infographics show..but Im subscribed to you

  • Plss tell us where we can get all these backgroud scores. They are too good 😍😍😍

  • Your videos are simply the best.

  • *uck my internet

  • Black hole:I’ll deal with it,guys!

  • What about bottom quarks? Aren't those denser? (I know top quarks are the densest, but they can't pair up)

  • -Necrocide Matter incoming-

  • Tiberium??

  • Other:weird matter Me an intellectual:cosmos zombie

  • Suggestion for a video: "How memories are formed?"

  • This is way too far. This is complete speculation. There is no evidence supporting any of this. It is only theoretical models that attempt to explain a few experimental results. I don't think this is the type of thing that Kurzgesagt should be presenting.

  • the music is awesome at the quark part

  • You should make a wideo about Brown Dwarfs

  • Science (from the Latin word scientia, meaning "knowledge") - source wikipedia Can't see any knowledge behind this video...

  • I am Locutus of Strange Matter. You will be assimilated. Resistance is futile but amusing.
