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 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❤️

  • Not really. You r thinking of traveling the universe by traditional propulsion,Trying to make something with mass travel @ the speed of light. However, if humanity can somehow manufacture and manipulate artifical gravity, which is the bending/distortion of spacetime. But unlike in nature, which is a by product mass in the spacetime continuum. Then instead of moving THROUGH space, you can MOVE space (and time). In a gravitational envelope, In which u can move faster than the speed of light. However u would need a stable version of element 116....

And its not like these technologies aren't based on some foundation of science. Wormholes, Warp drives, and my personal favorite hyperspace drives, while potentially hundreds of years away, are all possible methods of traveling faster than light.

Because if some galaxies have accelerated too far from us, before the first telescope was built, there's no way we can observe them.

  • I think if humanity can get to at least a type 3 civ and bordering into type 4 civ, we could start to create stars to counteract the acceleration of other stars and galaxies. This might be totally insane and maybe so dumb, but with not knowing the future it could work. Any science geeks out there who can say this could be possible? or at least be there even with all of the science fiction stuff? I mean its going to take a lot of energy and manpower to create stars and planets but could we make a planet which humans can live and help to counteract the acceleration?

  • Big bang theory was disproved by scientists in the latter part of the 20th century. They observed that stars etc were not all moving away from each other but were moving "randomly". Some moving closer and some further away. However this theory has been pushed for decades and it's now difficult to let go of.

  • 7:12 Starting from that point, what if they all "steer" each individual galaxies towards a central location where everybody eventually meets using technologies introduced in this channel like galaxy scale stellar engines or black hole bombs, so that they won't be separated from each other forever. The rest of the universe will still be lost to them, but they get so much more resources to spend before the eventual oblivion, a lot better than getting separated from each other forever by doing nothing.
