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: ruvid.net/video/video-ZL4yYHdDSWs.html 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: bit.ly/3dRJj71

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❤️

I wonder if the human species will ever truly die? I mean we probably will become extinct but future generations of species derived from us, will they advance on and create technology so advanced that they will be able to travel between universes? Wow

It’s incredible to think that billions upon billions of years into the future, humanity could have evolved into different branches of species that have accustomed into their surroundings. Basically sci-fi will become reality. A new form of racism would probably emerge from that wouldn’t it? It would be like history repeating itself in a more advanced manner. I wonder how long those species will stay humanoids? It’s pretty awsome to think that the human species and its expanding branches could spread out across the universe and not even k is it. We would be our own aliens discovering ourselves as living beings. In some way that already happened, with the universe spreading out. Millions of intelligent alien species that already lived and died out or are currently living. We are all connected in that way, the same universe. (And if you don’t believe in this next part then that’s fine) god is amazing!

Hmm. But what i don't understand is, like you said everything which is beyond the "horizon" travels relative to us faster than the speed of light. But If we go there with the speed of light, we would expand with the space, so we could also travel faster than light (relative to us) and could still travel there (even if our colleages on earth could not see us anymore). Or am I wrong?

I'm a bit confused. How do stars leaving the local group make them impossible to ever investigate, 'even with sci fi technology?' Isn't it just moving out into a void? What's stopping us from flying out after it?

It’s not frightening that we won’t be able to reach other galaxies but is depressing because there is a 80% chance that there is other intelligent life out there but we won’t be able to reach them in our current life time. Meaning no human on planet earth as I type this will see other intelligent life 😔

Well this suck. Or maybe not. Imagine there are multiple intelligent beings in far away place meeting each other and might be working together for better future and technologies while we are here isolated from the rest. But that might be a good thing tho, because hostile neighbors also exist, but without that we fight among ourselves. Although if the neighbors are stronger than us we'd be dead already.

So. I have a thought, now. Say we were able to open a wormhole to somewhere without first reaching the destination. Would that allow us to pass this border? I know it's totally theoretical, but just grasping at straws to comfort myself! Also, would that give us a window into the current state of whatever destination, as opposed to the millions of years old light that reaches us late?

I wonder what cosmological fact we will never be able to discover, because the only clues to it are already too far away or have dissapated. (just like future beings in a local cluster without background radiation and nothing visible outside the cluster)
Kenneth Bergan
I disagree with this. First off, although it may accelerate the speed at which a galaxy travels away from us when "exiting" the zone, that doesn't mean we also won't increase acceleration when we one day in the future travel on that very same path. Also, future technology may be uncomprehensible today, so the word "never" is completely inappropriate and should be avoided entirely.

Something so warm and fuzzy about the fact that the universe is so crazy, unpredictable, and mysterious, yet we exist and we're able to have these little complex lives. I'm not religious but there's something big way beyond our understanding working to make things come together in a way that just works out for us to exist and I think that's so fucking cool.
