    1. Kurzgesagt – In a Nutshell

      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:

        ADd closed captions maybe?

      5. Kadir Bilgin

        Please add Turkish subtitles.

    2. Da_ding

      Can someone explain me, why does the halking radiation gain speed during the time? While the surface of the event horizon is shrinking, and therefore the amount of "halking interactions" on the surface, during time, should decrease as well. (By the assumption that the halking radiation is konstant during space time

      At the 6:00 minute mark, there’s a reference to a singularity video, but no link. I’ve been searching for Kurzgesagt Singularity with no luck... anyone know where it is??

      I basically have more questions than answers now. But I guess that is normal with black holes.

      the video sus at 3:19 very sus among us

    30. The Gacha Professor

      Did you see the little among us character? lol

    31. NeighborhoodNinja

      Ooooo, so when Hawking says: There are ten million, million, million, million, million, million, million, million, million particles in the universe that we can observe. Your mama took the ugly ones and put them into one nerd. It was explaining about the life span of a blackhole.

    32. Gnagnagatt

      i just wanted to say if the laws of phisics simply do not aply anything is possible in a black hole maybe even seperate realitys

      After like 10 or so minutes of mind blowing stuff. I get hit by reality ehen he says he has made plushie lmao!!!!

    50. RussianFoe

      Coolest death would be to fall into a black hole ( i know you would die even before reaching it and it would hurt but that mirror effect damn )

    51. Mr. Ink

      We need arabic language please translate

    52. Skinny ASSC

      thanks now i know how to deal with black holes.

    53. Insert Name

      send the last humans to the right region near it so time travel will happen

    54. Recoil Mojo

      What if ~ Black hole white hole pair, matter that falls into the black hole is released into a new 'universe' or to a different place in our universe, recycling forever. Itzhack Bentov has an interesting model if you want to learn more

    56. Asad Ahmad

      Nice video

    57. Fernando Adrián Pedernera

      Most destructive entity in existence. Humanity makes a meme out of it. We shall prevail.

    58. C.A.P. Studios

      These black hole videos are so easy to rewatch it is crazy.

    59. blockify

      I always thought you could never actually see your self in third person. I was wrong

    60. Zenendrah Hernz

      I just feel so infinitely miniscule after those numbers :">

    61. VintageDragonfly

      Black Holes are one of my favorite cosmic and physics topics. I've watched and learned so much on them. And this video managed to give me a bit of existential crisis lol. Just the sheer overwhelming level of "nothingness" that lies beyond that event horison.

    62. M Something

      yeey, travel with Kurzgesagt ions into the future, where YOUR LOVED ONES ARE LONG DEAD, and see what the world will look like ^^

    63. Kylinity

    64. Achim Wokeschtla

      Why black holes are call black holes? Why black holes are usually illustrated as a disc with a certain diameter? That makes no sense at all! Black holes are one or more stars, which are 3-dimensional objects, collapsed in itself, which is still a 3-dimensional object, only a lot denser than the stars were before collapsing. The black holes are as much a sphere as the original star, only smaller and denser. The event horizon is not around a disc but around a sphere. Space is not warped downwards but around the sphere in all 3 dimensions of space. A black hole is not a hole in space to somewhere else. It’s matter so dense that space is warped around it. To me calling it black stars instead of black holes would make a lot more sense.

    65. Kartik jee

      Nice like always

    66. Longbow64

      So black holes last so long because how they slow time possibly?

    67. Jav Escobedo

      Ojalá que no descubran como crear un agujero negro en miniatura. Apágalo Otto apágalo.

    68. Longbow64

      Thats still a whole mess of energy

    69. Rick James

      I fell in a black hole if ya know what I’m talking about!!!!!!!

    70. Zayd Vestal

      anyone seen christopher nolan’s interstellar ?

    71. HallowedError

      Does the increase in the speed of space expansion affect these blackhole timelines?

    72. Shkhakh_Man25

      3:20 There’s an impostor among the birds 😳

    73. Longbow64

      Wait, time is linear.... YT commentor's opinion: you can only go foward or near stop, not backward..

    74. Longbow64

      Enter Event Horizon quotes........... Here:

    75. Allan Lu

      Yeah I'm trippin

    76. Heskiel

      third person mode and time travel woah

    77. Ka Dz

      what about 0,(9)=1 ? Is that means infinity isn't infinite?

    78. Fabri Fernández

      In spanish please😢

    79. oudonbail

      There is circular porthole structures, they are just as likely to be gateways as they are light absorbing machines with infinite energy. We still believe there is a sun inside the earth basically. Imagine the energy it would take to melt the core for millions of years. Why does the schuman resonance spike during major world events. The only thing we have worked out how to do is measure certain invisible forces around energy. Imagine if we just havnt made the right instrument to measure new energies or even powers that aren't based on electrical energy

    80. Rizvan ahmed Rafsan

      I loved the portal reference "there is no cake" reference ^-^

    81. Jaime Fernández Diz

      Mindblowing. I've just watched this video with a physicist friend and we have three questions. 1- How can the black holes generate their electric charge? If they are composed of "black hole matter" they shouldn't have it, or they should all have a charge proportional to their masses, and if it is due to charged particles they swallow, the electromagnetic field propagates as a wave at the speed of light, so it should not be able to go outside of the event horizon, should it? 2 - why the hawking radiation removes mass from the black hole? As I understand, it is in fact swallowing one particle, and gaining one particle of mass, not loosing it. 3 - this one is a thought experiment. If I had a very long rope, and I go near to a black hole and release the rope, so one extreme crosses the event horizon while I hold the other extreme (let's suppose I have an spaceship with enough power to keep me at a fixed distance of the black hole), what would happen? Would I be pulled into the black hole by the rope no matter what? Would the rope mechanically break due to the tension, with a piece falling inside and I keeping the other? Or once a particle of the rope crosses the event horizon it looses its bound to the rest of the rope and just falls on its own? Sorry for the long comment and the amount of questions and thank you for such amazing videos ❤

      1. Jaime Fernández Diz

        @Bồ Công Anh it captures my motion in time even if I am outside the event horizon? And as you said, what if it is a very big black hole so the tide force is small, and I, outside the black hole, have an engin which prevents me from falling, so only part of the rope croses the event horizon?

      2. Bồ Công Anh

        3. the tide will be strong enough that individual parts of the string will be rip into elementary particles and leave the rest trapped all forever. but speaking truthfully the rope and you will fall into black hole at the same rate without being stressed if the black hole is large enough,you won't feel the tide until you crossed event horizon. because black hole not just capture motion in space,they're also capture your motion in time,which mean,black hole deviated your orbit by capturing your "future".

      3. Bồ Công Anh

        1. the fundamental particles that make up matter and the universe are identical. what make you and me to be completely different is the information. how they are arranged. so as the stuff fells into the black hole,the tides ripped all matter back into elementary particles. and those particles has electric charges,and that charge add to the black hole. just like mass,a fundamental property that conserved. if your mass is 70kg, as you fell into the black hole,it suddenly becomes 70 kg more massive. 2. Hawking radiation is very complicated,Stephen Hawking was made an incorrect explanation for public to easier to swallow. But simple speaking,in the process,black hole absorbing negative energy. And according to Einstein's Famous Equation relationship between mass and energy E=mc^2. we can reverse it to m=E/c^2. and you can see that negative energy given us negative mass. which mean Total mass + negative mass = Less mass. so black hole losing its mass in the process.

    82. Tancredi Capucci

      My grandma always used to tell me. Never... Ever.. Trust a black hole....

    83. El Tio Spike

      That hourglass example was probably the most extreme analogy i've ever heard

    84. Jessie Taladua

      3:18 red sus

    85. MACHINE ID: V1

      "Something like a divide by zero error" It is quite literally a divide by zero error, density is mass divided by volume, and the volume equals zero.

    86. Joe Day

      Is the speed of light faster than the speed of a chemical reaction?

    87. Lavínia Sousa

      * God's grace * Did you know that God loves you so much that he sent Jesus to save us? Jesus is the son of God! And he loves you very much! To have proof of this, we can say that he emptied himself of all his glory and stepped on the earth! Isn't that wonderful? And there's more! He assured us of salvation! He fulfilled the mission that God gave him! Which is to have a death on the cross for all people in the world! * How do I get to heaven? * It's very simple! -Accept Jesus as your Lord and only Savior! - Repent of your sins daily even those you don't know because you sinned out of ignorance! -Recognize that you do not deserve God's salvation but even with your faults He wanted to save you with his great love and grace! Now about keeping your faith -Read the Bible daily -Pray and fast -Go to a church that follows the word of God May God bless you greatly! 👋

      Time travel ? Interesting

    89. Fecchi the illustrator

      merch looks very cool i wanna buy some in future

    90. gk with superior breaching


    91. riccardo manfrin

      4:43 I don't get why you are supposed to see no light while falling in a black hole.. I'd rather think the opposite occurs, since a LOT of bended light entering the black hole would have no other path to take than the one towards the center, hence would possibly find our eye balls in the way(?)

    92. mosquito boy

      3:19 please no-

    93. nitro99x

      Your videos are just so incredible awesome, even though many don't really matter since it's just hypothetical. Still I much enjoy listening to your uplifting way of explaining.

    94. Marian M

      I think it's pretty obvious the universe started off as a singularity, and it'll eventually end that way as well.

    95. Trey Wilcox

      Wait if Black Holes are from dying stars and a supernova is from a massive dying star wouldn't they have similar effect? Like are they two sides of the same coin?

    96. Sameh bouklikha

      this video should be you have it guys we don’t know everything we’re just making theories based on other theories that are half true lmao

    97. TheKaleab

      What if that's what made the big bang? All matter becoming a single singularity then boom it explodes and starts over again. This would fall in line with the "matter cannot be created or destroyed" saying.

    98. Joshua Marksberry

      If you think hitting a pothole is bad now, imagine running into a black hole.

    99. Khoomn

      There is a way to show people how long a black hole will live for, its very simple. Imagine trying to do a plank for a week straight, no breaks

    100. Brian Supreme

      Hi what about the spacetime contiuem in a nutshell? @kurzgesagt
