    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  Anos atrás +19373

    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: brclip.com/video/ZL4yYHdDSWs/video.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

      @zhain0 what did you mean by “didn’t say they shouldn’t”? My comment was meant to say that being put down for messing up a play is an example of mistakes being “looked down on”. That means they’re not normalized or accepted, despite the fact that they are incredibly common and normal.

    Cool vid! One question: How do we know we’re not living in a time where many galaxies already gotten out of view/disappeared(as our very distant descendants might perceive) instead of assuming there must have been a big bang based on current knowledge? Would love to see a video explaining that :)

      We do know that. That’s why we always refer to everything we see as the “observable” universe. There are many galaxies out there that we have never seen and will never be able to see.
      However, the CMB is still detectable so we’re still able to see the Big Bang.

    Thank you so much for your philosophy, I would definitely work with your team if I had the opportunity. About the video's subject, I'm really sad that our chances of getting contact with an extraterrestrial civilization are so low... But I'd like to witness the end of Earth's humanity in order to see what discoveries we would have made until the "end". What a life it could have been in the early Universe, with many neighbors just at some light years away!!

    For those who are curious as to why we won't be able to visibly detect galaxies outside the boarder, we first need to explain the process of red shift. Red shift is a process in which space itself is stretched due to dark energy (as stated in the video) which affects the frequency and wavelength of light as space is stretched so is the electromagnetic radiation of light, making it move to a lower frequency and higher wavelength. This is why there is a figurative border, once the electromagnetic radiation reaches such a low frequency, due to the distance of the source of light, it will be even harder to detect, and wouldn't even be visibly detectable because it would be similar to the frequency and wavelength of radio waves within the electromagnetic spectrum.

Left right? Front back and you say the universe WIl reach 0 kelvin but you fail to explain how can anything happen from the start if the universe as a whole was all ready in heat death or 0 kelvin from the start?😑I’m not confused it’s you that’s confused Beacuse you don’t understand 😑all you say is Big Bang and heat death but when somebody asks you HOW in the fabric of space the universe was created if their was nothing to be created in the first place ?😑also you can get something from nothing but only if you understand what nothing really is 😐death is just you entering a big snooze while being alive means to be awake from death 😐that’s how we came from nothing but what about the universe how can the ( entire ) universe of every galaxy be created if the universe had a beginning if their nothing to start any reactions?😑also just Beacuse the CMB has microwave radiation does NOT mean it was created from the Big Bang 😑just like the same microwave you cook your food in it’s not from a sudden explosion it’s just a form of energy and microwaves happen in the universe are naturally made nor from the Big Bang 14 billion years ago 😑also that’s the illusion of life life means to be awake from death or your endless sleep you don’t realize it Beacuse your alive but you only are a limited age physically but over all you have Ben dead for who knows how dam long before the day you were even born 😑

    Idk, 300 years ago I doubt any human could imagine what life would look like now and I read a lot of accounts from then. People often think that their age is the peak knowledge, and it always gets surpassed and left in the dust. I have no idea what the future will look like or how we will travel, but I have no doubts that humanity will figure it out eventually.
    Our understanding of the workings of the universe are simply lacking for us to imagine it now, hell we still don't even know what gravity is or why it occurs. I wouldn't be surprised if someone woke me millions of years into the future to tell me that we ended up creating new universes.

    And there's always the question if any of this is actually true. There's still so much we don't understand that it's possible that our current understanding of the universe is flawed or even completely incorrect. We're seeing such a tiny snapshot in the grand scheme of the universe, and are interpreting it with such little way to actually prove it. Correlations we see could just be flukes In the seemingly endless expanse of our universe's lifespan.

      @Jacob Maloney Great minds think alike bro, my exact thought was that with wormholes we could still reach those distant parts, at least hypothetically. But by the time we manage to achieve that massive feat of both physics and engineering, the universe will have expanded to the point where it will mostly be those vast and empty voids instead of clusters of different galaxies. So even if humans manage to invent wormholes, we're far more likely to open one that goes directly to nothingness.

      @Jorj X. McKie
      There is no such thing as multiple universes nor can we travel back in time.
      As to the point, in all this planet we do not have enough resources to power any vehicle faster then the speed of light. Nor do we have the tech to prevent such vehicle from turning to nothing from the immense friction / pressure that such speed would produce.
      In short, we will be stuck in our solar system for at most millions of years. To even reach the next star in our galaxy will take thousands of years or whichever time frame it is. Realistically speaking it seems improbable we will ever explore 1% of our galaxy. In short, we can forget about other galaxies. Although it is fairytale in my opinion, wormholes or instant traveling of light years in seconds is the only way to ever achieve total exploration of this universe. Without it, the distances in space are just to vast and incomprehensible to even comprehend in our lifetime / billions of lifetimes.

      @Jorj X. McKie You speak of the arrogance of certainty, I'm more concerned about the constant disparaging of what knowledge we have. It isn't complete, but it got us to the moon and back and that was a lifetime ago.
      If our knowledge was complete rubbish and littered with giant gaps that something so massive as 'you CAN go faster than the speed of light' could get through then we wouldn't have any functional technology at all, especially space tech.
      I would say we know enough to assert some things with confidence.
      Saying that the existence of innumerable universes cannot be ruled out is like speaking of god:
      1. You can't rule it out, because by it's very nature, evidence to the contrary is impossible to acquire
      2. Weather it exists or not, it has no impact on our reality whatsoever.

      ​@Jorj X. McKie The difference between the universe and the pond is that the universe is the friggin' universe. In order for a comparative 'rock' size disturbance to radically alter the universe, it would need to be the size of galaxy clusters and even then it's barely going to put a dent into it, it's so massive.
      I'm sorry, but you can't just fall back to 'you never know, science doesn't know everything' and fill out the gaps with fairy tales. While it's true that science doesn't know everything, at this point, we figured out quite a lot.
      We know that nothing can travel faster than the speed of light and even approaching it is nigh-impossible. We also know that the universe is expanding faster than the speed of light and thus, galaxies outside of the local group are getting away from us faster than even the fastest possible speed.

      And you might say 'oh but xyz years ago we didn't even think we could fly!' Yes, but other things could. Flight itself was not impossible. Nor was 'getting stuff around in space', because stuff goes around in space, we just had to get there.

      We can barely make it to the planets closest to us. We are currently dreaming about sending people to *Mars* . I'd say we need not to worry about all the stuff that is beyond our *hypothetical* reach, while our realistic reach is such an infinitesimally tiny fraction of it.
      The scale of our Galaxy alone is so immense that we likely cannot get around to exhausting all of it before the heat death of the universe.

      @Simple Key word is unless. So many people are cynical about Humanity's future because they spend 24/7 with their heads stuffed in the news reading every depressing thing happening every second across the planet and think that applies to everything.
      It's not naive or an optimist to be hopeful for Humanity's future. We make mistakes but it's always one step back two steps forward. We might have a dark age or regress slightly but it's temporary. As long as Humanity exists the advance of technology and development is unstoppable. If that's due to either Human greed or a desire to leave a better world for our children then it's up to you. The point however is indisputable.

      @AsaelTheBeast I agree completely. I just acknowledge that we should have a foothold on Mars just in case there's something like a cataclysmic impact with Earth or something life-ending. Other than that I think we should put all our energy into solving the abundant crises that continue to plague our ever-expanding environmental footprint. My deep sense is that of most conservatives: that man is a fallen creature and that a tech-utopia will always remain beyond our grasp because of our fundamentally myopic nature. If AGI is a reality it will probably wipe us out just as scifi authors always predict. : )
      Edit: I do wonder if fusion would be a solution to our problems or actually the death-certificate to our species. Unlimited energy = unlimited growth.

      Not sure what you mean. These are the facts as we understand them. They match the reality we observe. That's what theory means, not what I'm guessing you think it means, which is actually a hypothesis, i.e. a guess before the observation / validation.
      We may definitely be missing something, and we almost certainly are in that very hot brief period between the Universe's birth and our current epoch, but anything we miss has to fit within the known gaps in our knowledge, because that knowledge is verified with observation.

    Imagine making a video called "the speed computers will never reach" based on the mechanical physics of Babbage's Computing engine. Before new physics unlocked semiconductors and digital logic circuits unlocked modern computing. Similarly this is a good video for highlighting how far we can get based on engineering derived from relativistic physics, but physicists already know that's only a subset of physical possibilities. There are possibilities outside of spacetime, and as we better understand them, we will unlock new engineering tools to exploit them. Kinda hard to say we'll never get to these other galaxies, given that.

So if we start traveling with this sci-fi ship, would we be able to actually reach those galaxies that went beyond our limit?

    it occurred to me, if the big bang was an explosion with normal dynamics and physics, Then we would see a ripple anywhere in space seen as a pushing or pulling force on matter. Lets say the only reason we haven't seen it as the wave would be so large as how far we are from the center of the explosion the ripple may only be seen every 21,000 thousand years or something to large for our civilization to record with instruments that long. If you could determine the expanding ripple over distance and wavelength maybe you could look around a region for that time period EG 21,000 years to see the push and pull emitted. After looking it up it appears some scientists had the same idea and called it a gravitational wave lol. Imagine I studied this...

    4:28-- question, if we were to travel at light speed to a galaxy at the edge of our bubble and orbit around it AS it leaves the bubble, we could exit it, right? And go back using the same method? Doing these "galactic jumps", could we escape the observable universe and move on anywhere in the entire universe?
    Edit: oh I hadn't finished the video. But maybe after the expansion of the universe for a while, we can use new technology to split galaxies into smaller pieces and when it's too split up, just use new technology to pull the stars into nearby clusters and pull the clusters into a megagalaxy. By using the same jumping technology, you can pull out of reach parts of the galaxy back in.

    It kind of resembles what you would see if those distant galaxies fall into a black hole - there light will be red shifted and gradually fades away (time dilation from an outside observer's perspective - and their information will not be retrieved by us anymore. This also explains the accelerated expansion of the universe, which resembles the acceleration when an object falls into a black hole. So, perhaps the universe is geometrically shaped like a ball where all the far spaces merge into a single point, and is falling into a hugh black hole. (There's no theoretical size limit on how big a black hole can get, and it just get bigger and bigger as it eats, so statically one of them could get so huge that all of the universe will be affected by it). Who knows, maybe the great attractor is a sign of its pull.

    Hey guys. I just wanna let you know I love this show. And what you guys are doing is so cool and attractive. And makes me want to keep watching and learning.. I just turned my 15 year old niece on it and she can't stop. she is literally going through all the videos to catch up to where I'm at because I've watched pretty much all of your stuff. I want to thank you. keep up the good work. can't wait to see more. And possibly maybe one day meet 1 of you guys. And thank you personally. have a great day. wonderful day. Have a Kurzgesagt day.

    You know this channel is good when it gets people to care about something that would never affect them at all in their lifetime. ^^

      @Jesus is coming. Read the Gospel. just like it would be rude for someone to go onto a church service youtube video and talk about the various facts that make it unlikely for a creator god (like endogenous retroviruses), it is very rude for you to come onto a science vide and proselytize. shame on you.

    If someone at point A, could only see X far away, and the closest stars are just out of reach, could someone between point A and the closet stars still see them?
    Would faster than light travel change this limit, if a ship, a wormhole or something was created that could travel faster than the not only the speed of light but also the speed of the galaxies traveling away?
    What could exist in that other 94% of the universe we can't see? so many possibilities

    I am so impressed by the depth and breadth of this hypothetical nonsense, especially since this must be absolutely true in the Aristotlean sense yet we cannot solve the problem of cancer or climate change.

    If we assume that technology will continue to improve at any rate (meaning even 1 percent) for the next 1000 years,as it has the last century then we can also assume that at some point humanity will find a way to move as fast as,if not faster than the speed of light using warp drives. The problem with observable and unobservable universe is that as we progress towards these technological advances even though the universes are still drifting away, we will eventually catch up to them technically speaking and be able to observe them again and given any amount of time humans as a species will evolve sooner or later and we will be able to colonize the entirety of space. That is unless we go extinct sometime between now and then,given were only on one planet right now that might not be a very hard thing to happen. This reminds me of the great filter,where many civilizations have tried to reach our near future but never have been able to. As big as the universe is youd think we would at least see something out there. Some form of intelligence or life even if it was microscopic,which there may be we just dont know yet. So long as we reach the capability to colonize another world succesfully,humanity will never cease to exist. There is too much bioengineering inside of us and intelligence as a species that we hold that would force us to survive against the circumstances. We quite literally evolved on a planet that used to have dinosaurs and was on average 40 degrees colder than it is now and we complain about the winter months now because we have to wear sweaters. I think this was a good video, and so long as nothing happens to us within the time it takes to learn advanced space travel then we as a species will continue to expand. If we dont then the great filter does probably exist, and some other population in a distant universe will be given another chance at this.

    I want to ask a question that may seem daft but could wormholes open up to keep the passage of information between, distant galaxies. So that we can keep a constant temperature, across the universe (amongst many other things.) I'm know we probably couldn't use them for travel as beings, but for passage of information they'd be vital to keep the universe stable as it was born from the same stuff. Rather than them existing today, I don't believe they do.

    As planets expand farther from us, can’t we run into other galaxies that could expand in the direction of our planet?

    I don’t understand, why is everything moving away from us? I know you said the universe is expanding, but I still don’t get why that means everything is stretching away. Is there really nothing in the observable and unobservable universe that could be moving towards us? There’s no gravity connecting galaxies, so couldn’t there be stuff just moving in different directions?

    What if the universe is expanding more and more quickly because the universe itself is entering the event horizon of an unimaginably large black hole?
