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❤️

Frequency and matter are the 2 only things that are fact in the conscious universe. Time, speed, mass, ect are just ways humans confine the understanding of what you see the universe and existence to be.

    This video considers only linear travel based on our current knowledge, but doesn't take into account the fact that humanity could come up with science / technological breakthroughs that would make it possible to travel through space using alternative paths. It is like if caveman said : "the moon will be forever out of reach because the human can not fly!". You cannot predict what we will be able to do.

    After watching this clip a couple of times, I have a question to ask. To be sure this is only speculation but then I believe you have made another mistake or at least left something out. I believe you stated that in a few years (cosmically speaking) our stars will leave us and the universe will be dark outside of our cluster. I beg to differ as long as you stick to your calculations. Explanation for my thoughts! Pay attention for I do this once. So to start:
    We are in the Milkyway Galaxy, I believe and another being ( a heck of a long distance away) is in Galaxy XYZ495 and we are both being left alone by the other clusters by having them expand away from us. We can't see them and they can't see us but here is the kicker. A whole lot of the matter that is expanding away from us and a whole lot of matter that is expanding away from them is out of sight - but where has it gone? It hasn't dissolved, it has just moved away and part of what left them is expanding towards us. Thus in a few years, the clusters from Galaxy XYZ495 will appear in our night sky and become part of our universe. I can hardly wait! I'll only be 72,000,000 years young.

    What this video says is true but only from our current knowledge of the universe and from known science. It might be possible that the expansion of the universe slows down or reverts. And most important It might be possible that we discover some clarketech that let us circumvent the speed of light, or travel thru wormholes or something totally different that we don't know. After all it's only been few centuries since we even know these things and who knows what incredible technologies will we discover in the next 200, 1000, 5000 or 100.000 years from now!

    The nature of the Big Bang. The series of coincidence after coincidence. I am convinced that 99.9% of "outer space" is an elaborate illusion; one designed help pacify our minds to accept the limits of the universe made for us. A zoo is more palatable for an intelligent species if it doesn't seem to have walls or hard boundaries, but rather a series of "impractical" events to overcome.
