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?

    Kurzgesagt – In a Nutshell

    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 PS: If you want, check out our shop for some new posters about the universe posters and black hole plushies and stuff like that:

      This gave me a scary thought.... what if the galaxy we are in and why there isnt alien activity or federation to meet is simply that we possibly are in such a young galaxy and being so far in the edge of it we are truely alone.

      If we look at space through the eyes of science? We will never understand the meanings and true origins. We are all source beings that were all created at the beginning, and we have have live countless lives. You are connected to everything in the universe and soon enough those who recognize their true nature will be able to connect with all of the beings in the universes. How? We are already connected, we are all one. Look at the spiritual side of the universe. It may lead you into a place of better understanding and less speculation by ‘science.’ Just a thought Love to all❤️

    Interesting video, too bad none of this stuff is real. Planets don't even exist folks, above us there is a solid firmament that can't be passed. No one really knows what is beyond the firmament, those are the mysteries of God. But they don't want us the people to know the truth, so they keep filing our heads with this non-existent crap.

    So about the milkdromeda in the future if that's true. What if we're in the stage of thinking something that is not.. the populus or some people believe that the big bang theory is true what if it was different. And that the past had some actually far more advanced things then now but was erased. And civilization had to start over? While only retaining very little of our past history. You cant be sure that we were the first. Just like now how history is always being changed by the victors of different conflicts you cant be sure what truly happens sometimes. Then you have religion ir old textbooks and drawings etc that most people dont know never discovered,dont believe in, or are being kept secret to find our past. All of these scientists that say we were monkeys or we were fish and stuff cant be sure since they are just estimates.This is just a theory btw

    A bit confused how the farther local groups can move beyond where its light can never reach us. Wouldn't that mean it's traveling faster than light in our frame of reference (because as long as it's traveling slower than light, at some point in time light from it must reach us, even if it takes quadrillion quintillion gazillion years)? But nothing with physical mass can move beyond light speed (or even reach it), in any frame of reference, right?

    • Dimsum Densum
      Dimsum Densum

      @Yiğithan Kılınç but wouldn't the space have to be expanding at a rate at the speed of light or faster for light to not be able to reach us? Also, if the space in between is expanding that fast, wouldn't a star also be moving that fast in our frame of reference?
