    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:

  • HiPeopleIDKwhatIsGoingOn

    Honestly the way I want to go, I want to be made a scientist during death. By being launched into a black hole and reporting what it’s like back to a ship nearby. Or, is their gravitational force so strong that even radio waves n junk can’t escape? Also Kurzgesagt thank you so much for covering more on the topic of black holes! They are extremely interesting and I love the topic.

  • 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

    • Da_ding

      *(Konstant during space, time and gravity)

      Even in the context of the movie that is wrong. The future humans used the black hole as a medium to send the main guy to an extradimensional space. It wasn't the actual inside of a black hole.

    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.
