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?

    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

      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❤️

    At the beginning it stated that it was impossible even with science fiction technology… Star Trek alone has trans warp, worm holes, slipstream warp, warp 10(infinite velocity) and the technology of the Q continuum. All of which could achieve the goal of reaching seemingly impossible distances since they factor in faster than light travel.

    This is similar to what so called scientists said in the early 1900's (and earlier..the Catholic church, superstitious people etc.)..that eg: the human body can not travel faster than 50mph, then 100mph,then speed of sound, limited by their ignorance and unwillingness to accept change. The level of understanding of maths, science, physical limits and now so-called QM, is on a similar level now, as it was then. I believe that at the turn of each century, our basic understanding of the (mechanics) universe is only 10% more than the previous century. So don't delude yourself that we have come close to understanding the limits of the universe and our ability to comprehend how to find solutions to overcome our(outmoded scientists) preconceived ideas of how the universe should work.
