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?

    • If this 100th video comes out.. I'm forcing myself to watch it.. Regardless of how I'm feeling.. Even if I don't want to watch it

    • super video! hard and very effective work guys ! GL for future projects

    • Now the only science that you're missing is ascension sciences

  • That's why we got scientists to think for us

  • why do we not send a bunch of living cells and atoms out in space and to the other "Earth like planets" in our solar system so there can develop life in space? Then in the next few billion years or so the planets we have sent the cells and atom to, hopefully will develop intelligent life and then many discover each other. And if we did this, would that be a way of colonising the rest of the galaxy???

  • thx Kurzgesagt

  • why wouldn't a black hole be created if 2 neutron stars collided?

  • Wait so I spent my time teaching myself particle physics out of boredom and figured it was all useless... when really it’s not?! What about charm top and bottom...? What?!

  • Hello stranger 😊 Since you are here why not grab some stuff. 🍪 costs: nothing 🥛 costs: nothing Goodbye stranger 😊

  • Thanos: **snaps and kills half the universe** Strange matter: HOLD MY OUTER SHELL

  • Lets drop a nuke on it.

  • this is the same fucking date as the black hole pic came out and its jimmy neutron stars aint dissaponted just suprised

  • It reminds me of frogspawn

  • Strange matter: 4:06 Entropy: MY LIFE IS A LIE

  • At 6:34 - why Saturn is green?

    • 6:34 why is the bird talking lol

  • We had "The Walking Dead", now we'll have "The Walking Strange"

  • So strange matter is like reverse radioactivity? So stable that interferes with close molecules?

  • Finally, a good kurzgesagt video...

  • Seriously... it's nonsense. If there would be strange matter in neutron stars and if it would transform everything into more strange matter, then neutron stars would immediately become strange stars.

  • That's just hypothesis tho right?

    • everything is a theory

  • So, basically the plot of C&C Tiberium Universe... a meteor from a distant system comprised of neutron particles of a neutron star accidentally hits Earth and converts it into a neutron planet...

  • Do a video about scientific denial

  • What about the consciousness video? Part 2? Will you make it after 10 more videos?

  • I feel like they gave Kurzgesagt 700 20% discounts but 12 people who work for them used it before the video went up.

  • is all this strange matter thing just a hypothesis?

    • yup. we don't even know what's inside a neutron star.


  • I just realized that Kurzgesagt uses different intros for videos with different categories.

  • Please make a video about the history of Kurzgesagt! Who, when, where, how and why!

  • Can you do a video about fungi

  • I never knew Ratchet and clank had so much space knowledge to make captain quark all strange green and muscular hahaha well played

  • I am a strangelet.

  • Can anyone tell me how to pronounce the name of this brilliant youtube channel which fills me with a lot of curiosity and knowledge?

  • bill wurtz is subscribed to this channel, oh god.

  • Idk about this one friendo

  • I was waiting for this monster to be explained for a long time - thank you kurzgesagt. Another monster is gravitational strings, black hole in shape of a line that cuts thru anything and everything.

  • Quarks are hypothetical subatomic particles, which meaning, they don't exist. As such, your video is flawed. Do some better research next time.

  • Explain all dimensions

  • 2 Questions. 1Why doesnt the strangematter transforms back if the gravityproblem is solved? (like leaving the Neutronstar) 2 Why is it infectios? One tiny strangematterparticle shouldn´t have the mass to effect the others. I always sayed we´re living inside an massive black hole which will be swallowed by the next one. Its pretty much the one reason why the the distances of the Universe are not increasing so much. Its hold together from the massive Blackhole which will be swallowed and united by the small ones we see today in billion of years. Its not unlikely that the Gravity rules inside an universal size Black hole change and become less present. At least that theory fits with the always refreshing circles we see elswhere in Nature. And the fact that the inside of an neutron Star is similar to the Bigbang leads in that direction too.

  • No birds die eh?

  • I love You video

  • Alright kurzgesagt is basically getting bored

  • Hey,Japanese come on

  • Strange matters are humans (0_0)

  • is that a quack i heard 1:56

  • Either you're super stable or extremely high energy. Time to get energized

  • Most important thing in the universe: *S U B T O P E W D I E P I E*

  • yknow...i could have gone my whole life without knowing that at any moment we would be consumed by some green jizz

  • Is vacumm decay can kill a (fricking)blackhole

  • I'm not judging.

  • Me: Universe, how do you work... Universe: I could show you, *but I'd have to kill you*

  • strangelets the most deadly bean

  • If I wasn't a broke college kid I would donate to this channel monthly

  • Imagine if this was turned into a superweapon...

  • Does strange matter violate thermodynamics?

  • Much scared

  • what if was air was relplaste with helium

  • great! It's very useful

  • So strange matter is perfectly dense, as all things should be.

  • man kurzgesagt sucks now

  • someone know the Black hole picture

  • Hää Ist das jetzt ein deutscher Kanal oder englisch?

  • I would sign up for Brilliant, but me and my time are balls deep in computer science and physics courses.

  • *STRANGER THINGS theme starts to play*

  • I love this channel lol

  • What the... i can't understand. Am i weird?

  • Please upload more, I absolutely love your content!

  • how come strange matter is stable when strange quarks collapse back to down quarks when not in the cores of neutron stars?

  • Hmm strange

  • this is total bullshit. we would have evidence of this happening already. shit video

  • Thanos would like to meet these strangelets

  • Whatever happened to vacuum decay being the most efficient way to destroy the universe? God dang it, Kurzgesagt!

  • Red matter anyone?

  • 日本語字幕早くお願いします

  • Пожалуйста, кто-нибудь, добавьте русские субтитры.

  • Even strange matter needs a minimum of mass to be stable. Otherwise the LHC had destroyed the world so far. Secondly it is highly possible that our Solar System contains a lot of matter, who could came from Neutron star crashes.

  • Something I'm kinda wondering about is if it is possible to bring a piece of Jupiter to Earth

  • KURZGESGAT is my new netflix tbh !

  • is fffake!!!

  • i love your drawing style,it makes chem and physics so much more fun and interesting

  • I don't want to be a strange matter lmao :)

  • So we are a simulation with an error

  • Strangest Kurzgesagt video yet.

  • This is why I love astronomy

  • But if strange matter can do this, why hasn't it done so already?

  • Well that's just great. Space cancer!

  • lâu có vietsub vậy nhỉ

  • lâu có vietsub vậy nhỉ

  • 4:06 *Perfectly balanced, as everything should be.*

  • That moment when you are having a perfect normal Easter and see a video saying that at literally any fucking point in time you could be obliterated

  • So, Space cancer.

  • So why wouldn't the strange quarks within the neutron star spread and convert the neutron star into a quark star? Or... it always does, and the center of a black hole is indeed the quark star...

  • Strange Matter has joined the chat... Human: "Why do I hear boss music?..."

  • It is buskat.

  • @kurzgesagt you should make a documentary on the mysterious BERMUDA TRIANGLE That will be too good

  • was 688 a random number

  • Zombie Apocalypse: Nah! Small green beas that turns matters into themselves: We've got a problem

  • Can you make a vídeo about dark matter black holes Only if they exsist

  • I know what's the most dangerous stuff in the universe, these videos due to making me endlessly watch them, im stuck in a loop noooooo.

  • woo been a few months, now lets find out about yet another thing that could end our and the universes existence instantly.

  • 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
