The original Limits of Humanity:

Is there a border we will never cross? Are there places we will never reach, no matter how hard we try? It turns out, there are. Even with sci-fi technology, we are trapped in a limited pocket of the Universe and the finite stuff within it. How much universe is there for us and how far can we go?

  1. Kurzgesagt – In a Nutshell says:

    Hey Everybody! So this video is a remake and remaster of an older video that has a mistake in it. You can watch the original here:
    What is the mistake? In a nutshell: In the original video we said that it was PHYSICALLY impossible to leave the local group and reach other galaxy groups. That the rest of the universe is moving away from us too fast to catch up. But that’s wrong. It is not PHYSICALLY impossible to leave the Local Group, just extremely unlikely that we’ll ever do it.
    BUT: If you have a lot of time and a fast spaceship you can still get to a limited amount of galaxies – these galaxies will eventually get out of reach forever but until then, they are technically within reach. So why did we keep the video up and didn’t purge it when we deleted our addiction and refugee crisis videos?
    Well, it has to do with the nature and severity of the mistake: We did talk to a few astrophysicists to ask them what they thought and if we should take down the video. Their feedback was pretty clear, they thought it was still fine as the universe expansion things explained in the video are correct and they didn’t consider the local group thing as too major. This was actually a case of “good enough”.
    Also, back when this original upload happened, Kurzgesagt was operating at pretty tight margins and just redoing a video was not easy for us. Back then the team was small and we were fighting to put new videos out. So we just swallowed the bitter pill and kept the video around.
    But the video still bothered us, as far as we know this was the biggest unfixed mistake on the channel. Super frustrating, especially because the core idea of the video is so fascinating. The limit of our species. The actual limit. So yeah, we finally remade the video, sorry for taking this long, life got in the way.
    The original video will stay up, you can compare the two if you want to see how far we have come in a few years in terms of production quality. All in all, we could only grow the channel and work on getting better because of direct support from you guys. So thank you for that. – Philipp

    The phrase “Our galaxy is certainly big enough to entertain humanity” gives serious existential crisis vibes.

    • John Jacob Jingleheimer Smitty Werbenjagermanjensen says:

      @Cam Wight I was just thinking about that game before I read your comment now I’ll have to go play tonight

    • thejkhc says:

      we need humanity to work together to be able to achieve the ability to even entertain this idea.

    • Mateus de Assis Silva says:

      The whole video… better, the whole channel is a existential crisis trend!

      no not me
      im too scifi

  3. Cheng Teoh says:

    “94% of the galaxies that we can see are already unreachable” … that’s not even taking into account the 100% of the un-observable universe that’s out there.

    • Mystic Wine says:

      100% of everything out there and here, seen or unseen, or to be seen is 90% invisible at any given time!

    • OR AM I?????? says:

      @Big T I never said that. Infact, in our religion such people are called munafiqs (منافق) meaning hypocrites. Such people Allah absolutely hates and won’t accept any worship from. Keep going guys, I’m answering all the questions.

    • AbsurdPotato says:

      @ZachC331 lmao I’m losing brain cells reading this

    • Mackenzie Beeney says:

      Cue existential crisis.

    • ZachC331 says:

      @AbsurdPotato seems like you alrdy don’t have much to begin with if you can’t even come up with a counter argument 😼

    Universe: “No, you can’t just leave the local group!”
    Humanity: “Ha ha Alcubierre drive go brrrr”

    • kvykimo indelis says:

      @TI BONE yeah there are some papers out there but as ive said theyre still just cool theories. the reality is that we basically know nothing about the universe and for now any faster than light travel methods are more or less a meme

    • Chewy99 says:

      @kvykimo indelis It doesn’t require negative mass, it requires any sort of exotic matter.

    • Exousia says:

      I have read info about this theory.Could scientiests say it is possible or not?Do quantum mechanics say it’s bulshit?

    • TI BONE says:

      @kvykimo indelis Of course they are, those theories show necessity for ludicrous amounts of energy and thats without actually thinking about how such a thing could be build, even if those theories are right. In the end, we can only tell that within the limited understanding of the universe we have, it might theoretically be possible.

    • AbsurdPotato says:

      @kvykimo indelis yeah negative mass has not been discovered, but there are theories about dark matter that may allow that model of the alcubierre drive to work. We just have to wait and see. Also I think there are other warp drive models that can work without negative energy.

  5. Matthew Corridon says:

    We don’t take into account how beautiful this Earth is. The night sky, the stars, all will be gone in a certain amount of time. Thank you Kurzgesagt, for bringing this to light.

  6. Lucas the Dragon says:

    “The area of what we know is only surpassed by the circumference of what we don’t know.” -Albert Einstein

    • Alejo Tassile says:

      Oh boy, I get what you say, and I know it’s just a quote but…..
      πr²>2πr ?
      That doesn’t make sense unless the value of r stays below 2, and since we are increasing it… This just isn’t true

    • Doryan Vousemer says:

      And that area is also surpassed by the area of what we dont know we dont know.

    • Mystic Wine says:

      The Absolute cannot be circumscribed.

    • Chak Lee says:

      @Alejo Tassile we can easily define arbitrary units where it is true. But that doesn’t even matter! The quote is a visualization, not an equation.

  7. Messi says:

    Every Kurzgesagt video:
    – Facts
    – Scares you
    – Then calms you down
    – Add birds

  8. Aaron says:

    Now THIS is exactly the sort of existential dread I enjoy.
    It’s terrifying, enormous, yet comforting all at the same time.

  9. Reid Epperson says:

    This is possibly the most soul crushing Kurzgesagt video to date lmao.

  10. riverguy00 says:

    The scariest part of this is that something like this might have already happened to us, and we have no idea we’re missing something huge.
