The original Limits of Humanity: www.youtube.com/watch?v=ZL4yY...

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: de-vid.com/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

the galaxies could never get out of reach. if universe would expand 2000 lightyears a second every 500 thousand miles would still not be out of reach in theory ! in practic it would be cause we would have to catch the speed at which universe expands (good luck with calculations) :))))))))))))))))))))))))))))))))))))))))))))))))))))))) so universe expands but we can move in that space we can exit the solar system with a tone of dificulties but we can

I have my theory there are no dark energy and dark matter because the big bang make everything move with the explosion so it's slowing down by gravity and it mite expend because the edge of the universe is more matter then in the center so it's polling inside out and in our observable universe we see as expansion of the universe

If you honestly think humanity has limitations then you don’t know the history of humans very well. With advances in quantum entanglement and the new discovery about black holes and the former “information paradox” means we could be on the cusp of unimaginable potential in space travel and fourth demential movement. Humanity has no limitations because we are imperfect beings striving to find perfection without knowing what perfection even is.

The only comforting thing keeping me from having a mental breakdown is that it is possible for some kind of extremely advanced civilization appear from another universe (say it's Type 6 even) and then for it to help us break the border forever by some kind of darkmatter manipulation or something idk. The point is that the border might not be final as we don't know everything about the universe and the nature of it so this could as well just be false and we will become 12 dimensional gods and manipulate our multiverse. Things will happen, that's for sure.

And also:fun VERY IMPORTANT FUTURE HUMAN PEOPLE NEED TO KNOW: if 1 billion year from now has passed, there will be no like exept space stations. Continue the tradition until 7 billion years, then move to ganymede, it will be likely habitable for 9-16 million years then move unto titan, the sun will swallow mercury at that point, but titan will be habitable for at least 8-14 billion years, the final thing you need is stay on the kupier belts biggest object. Pluto. it will be habitable for 3 million years then the helium flash will occur. After that go launch back to earth then sun becomes white dwarf, its safe to say the past mercury/mercurian orbit will be habitable. Finnaly once the sun becomes black, safe to say you move on to trappist system and trappist 1-e and 1-f since 1d is being burned right at that time. Also very important but you need HUGE spaceships that carry up to 10000 people and give birth there to thrive(10000 people is enough to make them endangered)

I like to believe that we’ll eventually get to a point where we can manipulate space time and allow ourselves to almost “pull back” the edges of the universe in a way. Hope is our most powerful tool, never forget that.
Said Mohammed
God has told that you are in enclosed housing and has no exit. So the galaxy, the milky way and stars and earth are floating inside this enclosed housing that has no exit. Seven similar enclosed housing exists one over the other separated by atmospheric revers of the same distance of the enclosed housing. The stars are only existing in the lower housing. The seven enclosures are attached below the kursiy and above the kursiy is the place of the owner of the heavens and the earth the Supreme the Most high the Majesty the God of the universe.

This effed me up. I actually cried a little when he said that 16,000 stars pass over the horizon every second and are gone forever from us. My heart broke at the thought. Why is this concept so absolutely and utterly devastating? My brain is trying to grieve something it can't even comprehend both before and after it's actually happened. There's definitely a feeling of loss though, even if I can't even begin to grasp the size of it enough to properly articulate it.
Just a lone soul
I wish the words "never" and impossible" or "irritrievable", etc, would always (...or at least once...) be accompanied by "in the current state of science and technologies".... Because how would we know for real? All or most of our assumptions can only be based on what we know at the moment... Don't you think our ancestors (I'm speaking 2000 years, or this kind of scale) would have said the same about reaching the Moon, the Sun, other planets, having a space probe halfway out of our own solar system, actively trying to deflect asteroids, mastering fusion of atomic nuclei, growing human organs in labs.... Maybe we'll achieve some kind of power to be able to interact with, and modify some physical fields... Higgs, spacetime.... using black holes and white fountains... creating our own... Next level science-fiction ;-) But this video is (as all of them) an utterly good source of reflexion and deep thinking, that's a granted, and I'm debating for the intellectual pleasure, nothing else =)

I'm always in awe with theories like: "The formation of stars will continue to slow down". How on earth are we supposed to know this for certain? Universe is billions of billions years old (infinite to be exact) and human race is exploring it properly and forming theories for a very brief amount of time like last 100 years or less, so for me its always a bit like a belief system when it comes to astronomy

@MrPanSzymon because of the speed of light bro, we can see the past of the universe, and we can see the big bang. For example, if we see a planet that is 1000 thousand light years away we are seeing how that planet was 1000 years ago. So the further thing we can see is the big bang 13.8 light years away, so we know that's the beginning because there is nothing else further than that. Another example that helped me understand, is the Sun. The Sun is 8 light minutes away, so if the sun turns off, we will notice that 8 minutes later.

I don't think we can say with certainty that we won't reach these out of reach galaxies. The thing is even limited to the milky way, we'd have so much resources and time to become a type IV civilization with unlimited potential. A civilization with quadrillions of people and millions of geniuses together with advanced AI will for sure find a solution to traveling FTL given enough time.

[QUESTION] if we're supposed to be expanding faster NOW, I'd like to know how you came to that conclusion, how fast were we expanding before now? and how do you know? and where did you get your information from? As you look further OUT you look further BACK in time, so if the universe WAS expanding VERY quickly at the very beginning, and now that you look at the local distances mere millions of lightyears away, what direction is the vast majority of those galaxies travelling in? THAT is the ONLY thing you can say is how fast we WERE travelling compared to our local part of the visible universe. Where you get the idea that the universe WAS expanding quickly at the very beginning of the universe's life, the stars we observe are the stars light we ran into on our way through the universe as it used to be expanding, when we look out there, we're seeing the historical movement BACK THEN, NEVER NOW. REMEMBER THIS when you make any statement about astrophysics, you are always dealing with OLD DATA!

Unlike when Carl Sagan ignorantly blurbed that there were only 2 requirements to life in any planet in the 1960’s (making et life in the billions of likelihoods) we now know that there are hundreds of requirements and the likelihood of life ANYWHERE is so minute as to not really be possible HERE (were it not for the “fine tuning of a supernatural force”…Dr. Richard Dawkins). When you truly understand that life from non life is so statistically impossible, and the requirements for a single protein, gravity, mass, and on and on, you begin to see that the absurdity points to a creator and that He will show us all things in His perfect time.

@Dmytro Bogdan furthermore (and i'm not speaking directly on the topic of the big bang, which i am not well versed in), if it's a SCIENTIFIC theory, we can be maximally confident that it is the right answer. that's why they are theories and not hypotheses. scientific theories are the highest order of explanation, and although they very well may get more accurate as we bring in more knowledge and understanding, you can believe that they will not be overturned. one example is the germ theory of disease.
