  • Ok, phew. So we are done explaining any properties of black holes forever. If we ever talk about black holes in future videos we'll always link to this video. If you want to continue thinking about black holes a tad more, you can do so by getting one of the many black hole related things the Kurzgesagt team made with love:

  • Very insightful video and very beautiful too!! Animating that Ergosphere must've been days of work :O

  • "Not even light can escape the event horizon, how can you escape me?"

  • thanks

  • 3:03 "You will never reach the truth..."

  • these are the videos which should be on the trending page....!!

  • I love science I love animation THIS IS A GODLY CHANNEL I SUBBED!

  • Imagine dedicating your life to ideas and theories only to be proven false a few years later

  • Kinda a random question but since you've done a lot of space exploration videos, do you think we will be able to inhabitate other planets soon enough to survive. Also it would be funny if we had established in many different planets and evolve different although it would be risky since racism is a think in a single planet

  • Total crap

  • I feel like I’m watching little big planet

  • Note this is the remastered version

  • So the antimatter falling in to a black hole makes it loose mass, makes sense, but what stops the normal matter from falling in just as often? they should cancel out, no?

  • Entertaining and useful video making. Great job sir 👍👍

  • Feed me feed me kurzgesagt feed you what feed me INFORMATION

  • 3:19 Paimon sees an IMPOSTOR!

  • I was entertained, baffled and terrified all at the same time.

  • Won't you coooome 🎵 And wash away the rain🎵

  • The earth on tortoise reference portal 2 reference

  • Quality content!

  • This is the channel you watch before you go to sleep

  • When ever I think about the singularity, my brain breaks 🤯

  • Please talk about ants

  • So all singularities are the same? They're fungible tokens!

  • Potreste parlare delle singolarità infalling, outfalling e BKL?

  • Please make video on matrioshka brain

  • 3:19 Red was the Impostor, 1 Impostor Remains, that's where the impostors end up...

  • Can you eventually make a video on how nuclear work? I’ve never understood them. And you’ve helped me understand lots of things. So please make a video on them?

    • Nuclear what? Nuclear bombs? Nuclear reactions? Nuclear power generation? Atom cores?

  • Just found out about this channel and I'm quite excited, love the scientific content and the cartoonish looks of it, just got yourselfs a new subscriber!

  • 'This means that, in reality, black holes are even more screwed up than they usually get credit for.' Finally, someone to relate with.

  • 'As scary as the event horizon is, it keeps us safe from that drama.' World's Best Singularity 2021

  • 3:19 *red sus*

  • Could you please make a whole video about "negative mass"? I'm pretty sure it would be quite interesting.

    • @Jaana Ciccolella I don't think they will do that. With ISchats's algorithm, 10-minute videos would provide them with enough revenue to keep making more videos. Animating stuff costs a lot of money and so does researching scientific topics.

    • @Buxton Yes but it mustn't be a long video. Three minutes would be enough.

    • I don't think they'd have enough to talk about, negative mass stuff is purely theoretical and fringe science still. Would be sweet though.

  • 3:19 Amogus

  • Can you make a video about parrarell universes kurzgesagt? I would really appreciate it if you do so

  • Kinda explaining the ending of Interstellar haha

  • Turkish subtitle 🥺

  • The ergosphere would make an excellent source of energy.

  • i cant stop watching these

  • I'd love to see a video about dimensions. specifically dimensional existence.

  • Quasars video please

  • Hey make a video about white holes

  • Kurzgesagt is the best channel on ISchats.

  • Damn this took me down memory lane. Some of these segments are the exact same as one of your pervious black hole related videos. Fantastic


  • this is the best video on black holes i've seen

  • wut black hole-chan is safe it won't bite you

  • How do you know?

  • other science channels:use humans in their animation Kurzgezagt:we dont do that here

  • I hope you guys know noone has actually detected or seen a singularity. The prediction was done on the basis of mathematics, same with naked singularities. We are basically proving the maths we have been doing for a hundred years is correct and universe works the way we know. It is stupid and a total waste of time just cz you don't wana hear that we wasted so much of time proving something which didn't have a base. Singularity in mathematics is defined by infinite density in a 1D point, which is why Einstein simply laughed at this idea and moved on. I am sure blackholes don't work the way scientists want them to. But as humans, we lIke to predict stuff and put years into the research and then we realize neh. Same with the functioning of betelguese, we claim so many things about stars, yet we are not able to correctly predict the time of its supernova. So they opened a good window Rangin 300-400 years, and Hoping it would set off between this period. As a hardcore science student, I know the mindset of rest of the students. They are intrigued by black holes and stuff and this is wat they think is true. But it's not. Just to keep people engaged and keep getting the high funding, we are just moving along.

    • I hope you realize that every scientist knows this already, a theory is all we have until we can interact with a black hole's sigularity (aka never). So we just have to keep hammering on the theories until something pops out.

  • My head aches in a good way

  • Kurzgesagt, I wanna give you a big kiss for this guide, thank you!

  • I never seen in my life this like of animation

  • So it makes atoms smaller than atoms? God my brain hurts

  • That's why i watched "Doctor Who" so i can get TARDIS reference in "InaNetshell" Video.

  • Yadriel

  • How did I miss this video!

  • I think blackholes are recharging suns 🤔 after they burn up mass they collapse and suck mass again to burn like a cycle 🤔

  • Superman: I'm indestructible Blackhole: [burps in laughter]

  • This help me go to sleep better than ASMR

  • At 3:19 you can see among us still useing my mom's computer

  • I see among us and I'm useing my mom's computer

  • Does the singularity have to be a point? Like it has no size or dimensions?

  • Ok… now I am overwhelmed by the idea that time will keep on going so long that blackholes actually disapper

  • I don't know who needs to hear this, saving money won't make you a millionaire investing will ... Take out some money and invest ,Do it wisely Tho.

    • @Eugene Ralph okay Got it !! I hope he responds to me

    • @RichardDenisT

    • @Kittu Linda He's active on Tele-gram

    • @Eugene Ralph I'll like to know more about his services how can I contact him?

    • @Eugene Ralph He's a trade genius

  • Please make a video about longevity theory!

  • This video said that there's no good way to convey the lifetimes of supermassive black holes, but there is something that's helped me. Constructing a gear ratio of 1:10^100 is relatively easy, and watching the sprockets turn for a while is a great way to understand numbers of this magnitude.

  • "To survive the longest, you must do nothing." Deer watching car heading towards it at 50 mph: ok gr8

  • Hey Kurzgesagt, I’ve seen a page talking about white holes. Are they real and if so, how do they work?

    • They're still theoretical, they've talked about them in the wormhole video I believe.

  • What will happen if the core of the earth disappear

    • The planet would collapse and crush into a new round shape, completely changing it permanantly.

  • I feel like they are already explaining this in baby language yet still so many questions unanswered

  • Hola soy español.

  • What is germanys greatest invention? some may say the car, some may say Worldw... no noone would say that. but the real answer is: Kurzgesagt

  • thanks you

  • Holy Hanna. I think I need to go and lie down for a bit. Any thoughts on what happens to all the Hawkins radiation after it escapes the black hole?

    • Some people think the universe restarts somehow with the energy left (big bounce), other's think nothing happens and the universe dies forever as the universe expands too quickly (heat death)

  • You should change your name - from Kurzgesagt- in a nutshell to Kurzgesagt- in a black hole

  • Pls translate in italian

  • After watching this, I watched Interestellar. Regret nothing.

  • Hi,I love your videos very much and I appreciate your hard work very much.

  • 11:32 W H Y

  • Hey, the video was really nice, but Where's the duck quacking at the end of the video? I feel betrayed 😂

  • This comment will be Lost, but i think the best way of saying to anyone that they did a good job, is to thank them. So, thank you, for doing your work so well.

  • Who saw SpongeBobs pineapple at 4:51

  • 3:19 come on we all saw the among us dead body 😂

  • Nice

  • Nice 👍👍🙂 I love kurzgesagt 👍

  • I’m waiting for the day kurzgesagt fucking obliterates us and makes an earrape version of the intro

  • AMONG US 👁👄👁👍

  • Спасибо вам из России!) Даже с моим плохим английским, я прекрасно понимаю о тех будоражащих событиях, что происходят за пределами нашей повседневной земной человеческой жизни) Спасибо за вашу работу!

  • 10:35~10:36 take your screen shots guys, we have a new wallpaper!

  • Because in vietnamese

  • He did not do Vietnamese subtitles :(

  • 3:38 poor Mario

  • Amongus

  • We need vietsub


  • 3:18 AMOGUS

  • Hei Kurzgesagt, thanks for the amazing education video. I've learnt about blackhole from your videos. So far your videos are the best than others. But I do curious too about Oort Cloud, some matters in our very edge solar system. Few discussion about that and I wonder if your team would like to discuss or make video about it. Thank you

  • *_Please make a video on WHITE HOLES_*

  • This is the first video, I couldn’t follow along. So complicated
