Hey Everybody! So this video has a mistake and we remade it! You can watch the corrected and updated Version here: ruclips.net/video/uzkD5SeuwzM/видео.html What is the mistake? In a nutshell: It is not PHYSICALLY impossible to leave the Local Group as we said in this version. It is just extremely unlikely that we’ll ever do it, even for the standards of our videos. BUT: If you have a lot of time and a fast spaceship you can still fly to a limited amount of galaxies - these galaxies will eventually get out of reach forever but until then, they are within reach. Although every second some of them escape us forever. Ok, if this is so why did we keep the video up and not purge it when we deleted our addiction and refugee crisis videos? Well, it has to do with the nature and severity of the mistake: This mistake was much more straight forward then with the other two videos, so 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: kgs.link/shop
Since science as we know it is only some centuries old, I like to think that with so much time ahead of us, we could eventually find a solution right now unimaginable.
Or you know, maybe do stuff we've already imagined... like travel at close to the speed of light, to billions of galaxies within several Billion light years of us, build Dyson Spheres around each of their stars, modify those slightly into Shkadov Thrusters, and then move ALL OF THE STARS IN ALL OF THOSE GALAXIES TOGETHER SO THAT THEY'RE GRAVITATIONALLY BOUND. So yeah, there are plenty of options here, this video is definitely short sighted.
...There are actually 2 main issues here, I think. The first is thinking that just cuz the galaxies aren't gravitationally bound means that they will inevitably fly away from us forever, which is only true if we don't intervene (which we could, with the Shkadov thing). This is at least an understandable mistake on their part. The second issue is weird tho... they say we will never be able to even reach these galaxies beyond our local group, which is an absurd thing to say. I guess they assume we would try it with our current fastest tech, but that makes no sense. Everything within several billion light years is definitely reachable, and once u get there u could return too, it would only require going maybe half the speed of light. But u could reach millions of galaxies going just a few percent the speed of light so I really don't know what they're talking about. If u factor in the Expansion and the way it would speed up distant objects over time, we could STILL GET THERE so idk... usually Kurzgesagt is really accurate so watching this was just weird.
Traveling at half the speed of light is nothing, when we take into account how fast galaxies moves apart and the space between them. We would never get to them even traveling at the speed of light. So they were right about that. That said, we could find other ways of reaching them, like wormholes. So it’s still a bit shortsighted.
@@gilgamesh310 no that's just not true. If u do the math u would know that's not true. A galaxy 1 billion light years away moves away from us at 20,000 km/s. That is 1/15 (less than 7%) of light speed. A galaxy 2 billion light years away moves twice as fast away from us. If we went at half of light speed, we would reach these galaxies EASILY, the real question is whether we could get back at the same speed. The galaxies would be further away from earth by the time we got there, but not that much further. Again, if you do the math, we could get there, spend several million years accelerating the stars we find back towards earth (by making Shkadov Thrusters) and then make it all the way back. But the idea that we can't even leave the local group is crazy. Space isn't accelerating that quickly bro, it's just not.
@@janek8195 Space is accelerating supremely fast. I'm not sure where you got this 20,000km/s from but the galaxies are spread apart by dark matter faster than light. They're not technically moving, but space itself is, so they move in accordance. It's like how if you put marks in a balloon before blowing it up, and then see how they expand from one another after it's blown. The galaxies themselves don't move but space does.
This sounds like an epic fantasy. 'There was once a time when the galaxies shared light between them, But a day came when Dark Energy tore them apart. In the destruction that followed, two star crossed lovers, Milky Way and Andromeda, gave birth to a single child, Milkdromeda. That galaxy only knew stories about the rest of the universe, as Dark Energy divided them forever. But in that pocket of light, life grew.'
@@mr.q337 The Church of Milkdromeda Title: Milkdromedites Prophecy: The Milky Way and Andromeda will bear Milkdromeda. Life will end when Milkdromeda does. Faith: Spread life throughout the locality. Bad Stuff: Bias: Anyone on the outskirts of the locality is second class. Bad Religiosity: Destroy any technology that would allow us to leave the locality. *BOOM* done, like a character sheet in DnD
*Meanwhile in Kurzgesagt headquarters:* Manager: "Okay guys lets hear some fresh ideas for the next video.." Employee 1: "What about the end of humanity?" Employee 2: "What about some depression?" Employee 3: "What about birds?" Manager: "Yes"
And another question How much are we currently unable to see because we are physically too small to see and understand? Like how a virus is too small to ever acknowledge that it is inside a living being. For a virus, your blood vessels is the whole universe. What if we are in the same situation?
Our view isn't limited by inflation yet since we can currently still witness the big bang (in the form as the Cosmic Microwave Background Radiation), even though it's already fairly difficult to detect. In other words, when we gaze into the darkness the boundary that limits what we can see isn't distance but time.
Well, yes, that's what the term "observable universe" refers to. We can only see a distance of up to 13 billion years ago, because light from any further away hasn't existed for long enough to have reached us yet, and so everything beyond it cannot be observed.
I can't talk to my friend anything related to astronomy, like say, the size of the sun, without them pulling out the *EXISTENTIAL CRISIS LOL* card Which is another fancy way of saying "I want to stay ignorant and think my posts and likes are the center of the universe"
It's called gravity. Material things in the universe rotate around each other. When they get too close, they often collide and cause material destruction. There is nothing in the universe that doesn't abide by this principle. Getting too close to anything causes destruction, getting too far causes a different kind of destruction through isolation. And eventually, everything "dies" and becomes something else afterwards, leaving traces of influence through its existence. People think we don't live by this same principle, but we do. Same with cities, countries, civilizations, celestial bodies, etc.
6:33 We can't go out of our universe We can't go out of our observable universe We can't go out of over Galaxy cluster We can't go out of our Galaxy We can't go out of our solar system We can barely go to our one moon And now we and even get outta our house And I'm not done I can't get out of my bed
Daniel Colucci It’s implicitly mentioned because the one that always says my parents aren’t home is the female so technically he’s saying that andromeda is a male
@@GreenOrange755 Because there is the assumption that photons did not change over millions of jears and the distances are so vast that we see the light of stars which may be already gone. Funny enough there is no way to find out the one-way light speed, only the reflected one. So we may even see the one from one direction sooner then from another :)
Imagine a movie, where the protagonist and maybe, his or her crew, trying to find a way to survive away from the dying milkdromeda galaxy. Spanning through complete darkness, trying to reach the unknown, the legend of the myths, the other local groups of the universe. Very fascinating.
I watch these videos before bed because... When you think about whats out there all of our problems seem so small... like... why the hell are we all fighting each other rather than prepare for whats out there.
It's Okay!! Cheer up, man. I agree, most of the video was pretty depressing, but at the end, things got better! Besides, in my lifetime and yours, you never know, we may fly to a distant star within our own Galaxy, colonize alien worlds, and discover other forms of life. Although this isn't very far within the context of the universe, it will still seem amazing to us! And, at the end of the day, isn't that the only thing that matters? I would say so. 😊
+Talking Vidya (Producciones Zapata) Why? This had the exact opposite effect on me! We're alive during the spectacular fireworks explosion stage of the universe and we get to see all of it and study it to our heart's content! And as for whoever is around when the sky goes dark, they'll feel a lot more important than we do thinking they're the only things alive.. And being enclosed in solid black might be a little disheartening for us, but they wouldn't know anything else! I say screw the stars!
+Talking Vidya (Producciones Zapata) While most everything in this video is correct, it's also based on our current understanding of the universe and physics. Things can and DO change over time. Who knows, maybe further space exploration could be possible.
Always remember, this is just based on our current understanding of the universe and there are millions of years to expand our knowledge till the scenario happens.
With human stupidity, wars, pandemics, pollution and cosmic threats? Not likely. Don' get me wrong, I'd love for humans to be able to master intergalactic travel just as much as anyone else. But I just don't see our civilization existing in the next couple of hundred years.
I have no theoretical evidence but I assume that humans are an adaptable bunch. We likely won’t be as abundant are we are now but I actually believe that some humans are still going to be here for a long time assuming that a meteor doesn’t hit us.
And you think humans,as we presently are,with greed,religion,self pity etc will live the millions of years required and gather that knowledge? You my friend,are the ultimate optimist.
@Time Future "My personality"?!...you could not guess it if I gave you a million chances!...from a very early age,I ALWAYS wanted to "help" others...with no thoughts of benefit/reward...I became a carer after graduating.. ..in my work I have seen greed,cunning,betrayal etc etc that you would not believe...and all this from one "loved" one to another...family to family etc etc...I still have faith in humanity,but it's a very close run thing. So please do not tell me about "personality"...your sly dig sure implies a lot about YOUR "Personality"! Have a good life.
I like how everyone thinks this is how things are and will be in the future, this video is just based on our current understanding of the universe. We can only see the effects of dark energy at the moment which shows how little we actually know but in the future we may discover something that could change our entire concept of the universe; making the impossible possible.
I don't think it matters that much. Not being able to leave the local group? Who cares when we are nowhere near of exploring just our own galaxy. I would be content with contact with just one other intelligent lifeform but even that seems impossible now.
+Crux We know so little it's insane what science hides there things like FTL travel even travelling between galaxies can be just a trivial thing in the distant future. If we survive of course.
+Crux yea its weird that not many people realize that nearly everything we know about our universe is a "theory" meaning IMPORTANT DETAILS could be wrong
The most fascinating fact is that the universe is still expanding and at an accelerated rate. Even more fascinating is that beyond the observable universe we could just be one universe in a pocket of other universes we will never know about. It's amazing.
But what's cool is that while the observable universe ends at the particle horizon where the universe became transparent, the effects of gravity from unobservable regions have still effected our universe very early on, resulting in what's known as "dark flow". It's a bit disputed whether the dark flow is negligible or not though.
@@batman3698 Uhm... yeah... No, actually. Your understanding is just a bit superficial here. Actually, its even rather unlikely this whole 'The drifting away of Galaxys traps us alllll! Ohhhh!'. Nah, not really. I repeat, for a fact, science assumes a lot and this video does not do a disclaimer about this. Which is bad.
@@loturzelrestaurant Galaxies are moving apart faster than light, and matter can't accelerate to the speed of light. Both of which are proven. That being said, this doesn't necessarily make it impossible to reach distant galaxies, it just takes a really really really really long time.
+gijsjaradijsja It's already true. We can't see everything. Notice he said 'Observable Universe'? There is much of the universe we will never ever see already.
+Richard Clutterbuck I am not a pro at this but I think observable universe is a combination of light that has reached us plus the increasing diameter of hubble sphere capturing new lights. We infer 70% of our galaxy with other means - true, but also because information is already within reach. Almost all of unobservable universe will remain so as it's receding away faster than light speed, so we will never know the full story. The real edge of universe will never be seen (as it stands).
+gijsjaradijsja What he's trying to say is that people in the far future won't have a clue about the Big Bang. They will know that they evolved, they will know about the particles, molecules etc. They will know everything we know today and maybe more, they just won't have a clue about the past, as to how that galaxy formed. And they won't be able to observe anything passed that galaxy.
+The Codfather Maybe if you were a Galaxy... We're much too small to have that lonely feeling. We have more than enough room and plenty of things within it.
"we are an OG civilisation that got to see all the cool bits of the universe" well...maybe not ALL the cool bits) there is always a chance that what we see now is just a 0.000001% of what was available billions of years ago

This is a mind-blowing, humbling, and utterly terrifying video. Even with science fiction-type of technologies, we as a species are limited to the local group, to one hundred billionth of a percent of the observable universe. That's crazy. It seems impossible. On the one hand, why should it matter? Our own galaxy alone has 100s of billions of stars, limitless as far as the time our species has/will exist is concerned. Yet somehow it feels incredibly isolating to see so much more out there and know not just that we cannot visit it, but that it is forever beyond our reach. The Kurzgesagt staff managed to manufacture a deep sense of desolation and despair. Impressive. Thanks.
There is a theory that that will happen naturally but when it gets pulled back it basically squishes together and then forms another big bang. Its called the big bounce.
Watching all your videos backwards since i subbed last week (yep I've watched that much Kurzgesagt!) This old intro diddy took me by surprise. I much like the newer one. Also your current day animations show so much growth yet the quality of the written content of every single video even this far back has been really great and thought provoking. I really love this channel now :)
It was at 5:50 when you guys said that beings born in the far future won't have any way of knowing about the Big Bang that really got me. It made me think, "How much is there that we humans will never know because we arose too late?" Then I thought, "This is why our knowledge is so important. We must preserve it and keep it safe for future species!" Oh, Universe! So beautiful and scary. You are so much darker, mysterious and bountiful than any religion could be to me. I hope we never stop learning from you, terrifying though you are.
I wouldn't be surprised if some of the celestial bodies we see are actually artificial structures built to keep and maintain knowledge of past civilizations.
Sasaki Umiquema Eat your vegetables, learn all about the human body and genetics, and become a billionaire and you might. It's only a matter of time before we can either upload our consciousness or keep our bodies alive for a few hundred years then transfer our consciousness into new ones. If you're an unethical billionaire (is there any other kind, you try generating a billion dollars without ever breaking any ethical principles) it may be possible in your life time.
These videos are motivating me to do useful things. It makes me wonder about science and technology. And the feeling of knowing you are doing something useful at the moment, leads me to be happy the rest of the day. Thank you for all of these Kurzgesagt
The fact that we're supposed to be born at the perfect time to understand our universe doesn't convince me. If we were born in milkdromeda, we may think the same again. It's very probable that there's a much bigger history that we're missing out on.
+David M. Johnston What if what is described in this video has already happened to some extent? And our observable universe is only a fraction of what is really out there and we will never be able to observe the rest because it's already too far gone?
+David M. Johnston Agreed. The only reason it seems special (or we seem special) is because we exist here to find what is special about it. It's the paradox of perspective.
It's the present that we're missing out on as our perception of the edges of the observable universe is extremely late... as if a "present" time slice even works that far away... relativity confuses the hell outta me...
but hey, the universe right now is pretty too! perhaps million years from now, an exact person would've said the same thing but they wished to be born in the same time as us :D I feel like we should just be grateful for what the universe has given us in this time
I agree! Even though this pandemic may be a bad time. Assuming we all make it, this likely is the best time to be alive. We have the internet, education is available here on RUclips, and you likely can improve your financial means assuming you are living in the developed world. I believe that the best time to alive is this era.
"Even with science fiction technology, we are trapped in our pocket of the universe..." The thing with science fiction, or fiction in general, is the fact that there is no limit; if you can imagine it, it can be done...in fiction.
Fiction has a lot of limits. In order to uphold the suspension of disbelief (i.e. have the reader take your universe seriously) you have to adhere to the rules you yourself put forth. This is called Magic A is Magic A. Theoretically, for example, the Harry Potter universe has magic. But the magic is quite tightly codified, and that's how we can take it seriously. If Dumbledore summons a phoenix, it's within the bounds of established reality. If Dumbledore collapses the local cluster and turns it into butterflies, that would destroy the fabric of the fiction itself. Obviously you can write a work in which everything can be done, like "and just like that, John leapt to the edge of the observable universe". But you'd be hard-pressed to have anyone take your 'fiction' any seriously than we do random ramblings.
@@Muircetach To achieve reader believability while breaking a limit, there are several ways of doing this. (1) Distract the reader with more pressing matters; a plot, a threat, survival, just anything urgent or compelling will do, (2) Just break one limit and keep the rest; for example, just because a futuristic starship can travel instantly travel millions of light years in an instant, does not mean it can time travel or create energy out of thin air, both of which are arguably more difficult, or (3) Incur a cost or penalty; in Back to the Future, the Delorean originally requires Plutonium to power; Voldemort has to tear apart his soul to achieve immortality, or at least the fantasy of it. In short, there is not really any limits in fiction, or to put it in a more conservative manner, you can set the limits just enough for whatever it is you need it for, so long as you are creative enough to frame it in a way that is logical and believable.
Accually, there exist something human cannot imagine or describe. Ex. Almost no way for writer to portray 4-dimension objects, even indeed they exist in our dialy life.
Once again, that you Kurzgesagt for an amazing video. I'm always looking forward to you videos, especially about space, even if that means a small existential crisis.
“Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.” Douglas Adams
+loothootyou Not depressing, joyful! We exist in a unique time where we can right now perceive the beginning and the end...unlike beings before or after this time (well, at least after). Think about your life... you don't exist during the time of the Romans nor when we are a Type 3 civilization (or extinct)...but you can understand both ends and enjoy your time as it is...and enjoy running water and electricity!
+loothootyou look at the bright side, most likely humanity won't survive long enough to observe the disappearing of galaxies from the night's sky. Or the forming of Milkdromeda. Or anything that resembles world peace.
Nop.... never gonna happen, we will never achieve speed of light (actually talking about EM wave in general). Our atoms are even bound by EM wave which hold nucleus and electrons together. At speed of light, in simple words, it might disintegrate. To make it worse, the universe expanding not at speed of light......even greater than that because the space is expanding (Note: its not that they are moving greater than speed of light)
I like to think that the more we learn about how the universe works, and the more we develop our technology and awareness, we'll find that our limits will continue to be broken. It could be only a matter of time before we discover interstellar travel that will make traveling vast distances possible even if there are very sound reasons to think it's impossible.

@@SauhardaBista right now we are just constantly, researching trying to know more and we still know the basic things, but there is a lot about those basic things that we don't know. Its like we know alphabets and we are trying to make words. I just think its beautiful
@@SauhardaBista We'll never know "most of the things" becaure there are a lot of it out there, and there are a lot which we don't know even to exist. Living in the past wouldn't be different to live in our days (exept for low life). All the innovations that you read about in the history books, weren't just popping out like magic. They were long processes that in the end led to the innovation, just like in our days :) Every day we "discover" something new, but still, to a "normal" person it doesn't seem so :)
Good news! You'll be happy to know that we will ALWAYS know a lot, and still know nothing. Yes, in the last few centuries, we went from guesswork to educated guesswork (the Scientific Revolution) and have been doing a little better when it comes to forming an idea of how the world works, but the number of questions only ever seems to increase.
This raises some interesting philosophical questions about knowledge itself. Would anyone really blame the Milkdromedans for thinking their cluster was the only one that existed? While we would know this is wrong, they would have no way of actually knowing so, and all evidence would support their conclusion that they are isolated. What I'm trying to say is that is it in fact possible to know the actual truth of anything? What we consider truth is based on what we observe, and what we observe can change over time, thus changing what we consider truth.
Daniel Olowu I was thinking the same thing while watching this. How do we know what actually happened in the beginning actually happened when evidence of what actually happened changes over time? This is so eye-opening
Yeah, what if the universe as we know it today is actually in its own “pocket” separated even further from other “pockets?” What we think is the entire universe is only what we can detect, like what the Milkdromedans of the future will think the observable universe is just their supercluster.
@@samtherat6 I thought the same. But I think the difference is that we are currently able to see how the universe began, while the Milkdromedans wouldn’t
@@samtherat6 Exactly my thought. Maybe all of space is filled with pockets of matter, endlessly. There is no way to know with conventionell technology (bound by lightspeed). And if you think further, what if the fastening expension of the observeable universe is caused by the gravity of these other universe pockets which are possibly masswise statisticly even distributed around our observeable universe in the longrun. So Einstein was right with dark matter beeing the biggest blunder in his carreer.
Yup, I definitely believe so... We wouldn't know what major secret may be missing that would make us have the rewrite the entire history of the universe...
What if advanced aliens haven't contacted us because we are one of the last primitive planet in the universe and they are preserving us like we do the uncontacted tribes
There is no way for "advanced aliens" to even know that we exist unless they live within 200 lightyears of reach from earth (which is unlikely to say the least).
6:05 "They will have no way of knowing what we know today" I like to think of some sort of life that has lived before the big bang and has predicted a post big bang life like us, coming up with the same sentence
How do we know that some ancient civilization billions of years back said the exact same thing and the universe that we think is everything is actually just a tiny speck?
The common assumption in cosmology that that there are parts of the universe that we cannot see. It is currently believed that the early universe expanded so fast that the light from most of it has not reached us yet. I would add that most of our knowledge on the universe is very recent and dark energy was only discovered around the year 2000. We should conclude that our views of the universe will still undergo drastic changes in the coming decades and centuries.
So if in the distant future, the observable universe will only be our local group, and it will appear as an isolated static system with no way to show otherwise... is it possible that an analogous illusion is being played on us right now? Like that we are in a larger, static universe, but some event caused an expansion of our local pocket (the observable universe) , leading us to incorrectly deduce the big bang and stuff? For the record, I believe in the big bang as strongly as I believe in anything. Just curious, that's all.
Yea, its very possible, we just use the information we have as of right now to make predictions. That's another reason why we say the "observable" universe, because it could be so much bigger than we actually know
It is possible, we would have know way to know one way or the other, so we just assume what we see is the origin because for us it effectively is irrespective of anything that could've come before.
If you think about it everything is so small. I mean we look at bacteria and say those things are microscopic but maybe some being out there just looks at the universe like that thing is so small. Idk Bruh shit be wild
Imagine living in a civilization where you think you're just a single galaxy in the middle of an endless void, people would theorise whether or not there's more places out there, though noone would ever be able to prove it.
We already live in the middle of an endless void. Since we are the observers, we are in the middle, and beyond the limit of observable light, there is only what we could call "void" at least not in a technical meaning. So it doesn't change that much. That logic goes further if you think that is not that easy to visit even our moon... Or planets in our solar system*.
Hey Everybody! So this video has a mistake and we remade it! You can watch the corrected and updated Version here: ruclips.net/video/uzkD5SeuwzM/видео.html
What is the mistake? In a nutshell: It is not PHYSICALLY impossible to leave the Local Group as we said in this version. It is just extremely unlikely that we’ll ever do it, even for the standards of our videos.
BUT: If you have a lot of time and a fast spaceship you can still fly to a limited amount of galaxies - these galaxies will eventually get out of reach forever but until then, they are within reach. Although every second some of them escape us forever.
Ok, if this is so why did we keep the video up and not purge it when we deleted our addiction and refugee crisis videos? Well, it has to do with the nature and severity of the mistake: This mistake was much more straight forward then with the other two videos, so 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

Actually, all this is just an Assumption.
Since science as we know it is only some centuries old, I like to think that with so much time ahead of us, we could eventually find a solution right now unimaginable.
Or you know, maybe do stuff we've already imagined... like travel at close to the speed of light, to billions of galaxies within several Billion light years of us, build Dyson Spheres around each of their stars, modify those slightly into Shkadov Thrusters, and then move ALL OF THE STARS IN ALL OF THOSE GALAXIES TOGETHER SO THAT THEY'RE GRAVITATIONALLY BOUND. So yeah, there are plenty of options here, this video is definitely short sighted.
...There are actually 2 main issues here, I think. The first is thinking that just cuz the galaxies aren't gravitationally bound means that they will inevitably fly away from us forever, which is only true if we don't intervene (which we could, with the Shkadov thing). This is at least an understandable mistake on their part.
The second issue is weird tho... they say we will never be able to even reach these galaxies beyond our local group, which is an absurd thing to say. I guess they assume we would try it with our current fastest tech, but that makes no sense. Everything within several billion light years is definitely reachable, and once u get there u could return too, it would only require going maybe half the speed of light. But u could reach millions of galaxies going just a few percent the speed of light so I really don't know what they're talking about. If u factor in the Expansion and the way it would speed up distant objects over time, we could STILL GET THERE so idk... usually Kurzgesagt is really accurate so watching this was just weird.
Traveling at half the speed of light is nothing, when we take into account how fast galaxies moves apart and the space between them. We would never get to them even traveling at the speed of light. So they were right about that. That said, we could find other ways of reaching them, like wormholes. So it’s still a bit shortsighted.
@@gilgamesh310 no that's just not true. If u do the math u would know that's not true. A galaxy 1 billion light years away moves away from us at 20,000 km/s. That is 1/15 (less than 7%) of light speed. A galaxy 2 billion light years away moves twice as fast away from us. If we went at half of light speed, we would reach these galaxies EASILY, the real question is whether we could get back at the same speed. The galaxies would be further away from earth by the time we got there, but not that much further. Again, if you do the math, we could get there, spend several million years accelerating the stars we find back towards earth (by making Shkadov Thrusters) and then make it all the way back. But the idea that we can't even leave the local group is crazy. Space isn't accelerating that quickly bro, it's just not.
@@janek8195 Space is accelerating supremely fast. I'm not sure where you got this 20,000km/s from but the galaxies are spread apart by dark matter faster than light. They're not technically moving, but space itself is, so they move in accordance. It's like how if you put marks in a balloon before blowing it up, and then see how they expand from one another after it's blown. The galaxies themselves don't move but space does.

The real question here is, how much knowledge have we lost due to this expansion?
4K Squad Damn.......we will never know
And another question
How much are we currently unable to see because we are physically too small to see and understand? Like how a virus is too small to ever acknowledge that it is inside a living being. For a virus, your blood vessels is the whole universe. What if we are in the same situation?
Look into the night sky
See if you can see any galaxies up there
That’s what telescopes will see in the future
Our view isn't limited by inflation yet since we can currently still witness the big bang (in the form as the Cosmic Microwave Background Radiation), even though it's already fairly difficult to detect. In other words, when we gaze into the darkness the boundary that limits what we can see isn't distance but time.
@@keyboardwarrior2418 holy shot I’m too high for this
Imagine if our "universe" is something like the local group and everything else is far away

Well, yes, that's what the term "observable universe" refers to. We can only see a distance of up to 13 billion years ago, because light from any further away hasn't existed for long enough to have reached us yet, and so everything beyond it cannot be observed.

Yeah, that's more less galactic distancing
It's called gravity. Material things in the universe rotate around each other. When they get too close, they often collide and cause material destruction. There is nothing in the universe that doesn't abide by this principle. Getting too close to anything causes destruction, getting too far causes a different kind of destruction through isolation. And eventually, everything "dies" and becomes something else afterwards, leaving traces of influence through its existence.
People think we don't live by this same principle, but we do. Same with cities, countries, civilizations, celestial bodies, etc.

+Talking Vidya (Producciones Zapata) i understand
It's Okay!! Cheer up, man. I agree, most of the video was pretty depressing, but at the end, things got better! Besides, in my lifetime and yours, you never know, we may fly to a distant star within our own Galaxy, colonize alien worlds, and discover other forms of life. Although this isn't very far within the context of the universe, it will still seem amazing to us! And, at the end of the day, isn't that the only thing that matters? I would say so. 😊
Google Edgar Cayce. That should cure it :)
+Talking Vidya (Producciones Zapata) Why? This had the exact opposite effect on me! We're alive during the spectacular fireworks explosion stage of the universe and we get to see all of it and study it to our heart's content! And as for whoever is around when the sky goes dark, they'll feel a lot more important than we do thinking they're the only things alive.. And being enclosed in solid black might be a little disheartening for us, but they wouldn't know anything else! I say screw the stars!
+Talking Vidya (Producciones Zapata) While most everything in this video is correct, it's also based on our current understanding of the universe and physics. Things can and DO change over time. Who knows, maybe further space exploration could be possible.
Always remember, this is just based on our current understanding of the universe and there are millions of years to expand our knowledge till the scenario happens.
With human stupidity, wars, pandemics, pollution and cosmic threats? Not likely. Don' get me wrong, I'd love for humans to be able to master intergalactic travel just as much as anyone else. But I just don't see our civilization existing in the next couple of hundred years.
your sentence simplified: theoretically
I have no theoretical evidence but I assume that humans are an adaptable bunch. We likely won’t be as abundant are we are now but I actually believe that some humans are still going to be here for a long time assuming that a meteor doesn’t hit us.
And you think humans,as we presently are,with greed,religion,self pity etc will live the millions of years required and gather that knowledge?
You my friend,are the ultimate optimist.

Seeing this and the new video truly shows how much time has passed , it didn’t feel so long ago this original video came up...
I like how everyone thinks this is how things are and will be in the future, this video is just based on our current understanding of the universe. We can only see the effects of dark energy at the moment which shows how little we actually know but in the future we may discover something that could change our entire concept of the universe; making the impossible possible.
Exactly.
I don't think it matters that much. Not being able to leave the local group? Who cares when we are nowhere near of exploring just our own galaxy. I would be content with contact with just one other intelligent lifeform but even that seems impossible now.

The most fascinating fact is that the universe is still expanding and at an accelerated rate. Even more fascinating is that beyond the observable universe we could just be one universe in a pocket of other universes we will never know about. It's amazing.
But what's cool is that while the observable universe ends at the particle horizon where the universe became transparent, the effects of gravity from unobservable regions have still effected our universe very early on, resulting in what's known as "dark flow". It's a bit disputed whether the dark flow is negligible or not though.

All of, more or less.

+Richard Clutterbuck I am not a pro at this but I think observable universe is a combination of light that has reached us plus the increasing diameter of hubble sphere capturing new lights. We infer 70% of our galaxy with other means - true, but also because information is already within reach. Almost all of unobservable universe will remain so as it's receding away faster than light speed, so we will never know the full story. The real edge of universe will never be seen (as it stands).
+gijsjaradijsja What he's trying to say is that people in the far future won't have a clue about the Big Bang. They will know that they evolved, they will know about the particles, molecules etc. They will know everything we know today and maybe more, they just won't have a clue about the past, as to how that galaxy formed. And they won't be able to observe anything passed that galaxy.

That visual of the alien hand just barely out of reach of the human hand is such a powerful and depressing visual.
This is a mind-blowing, humbling, and utterly terrifying video. Even with science fiction-type of technologies, we as a species are limited to the local group, to one hundred billionth of a percent of the observable universe. That's crazy. It seems impossible. On the one hand, why should it matter? Our own galaxy alone has 100s of billions of stars, limitless as far as the time our species has/will exist is concerned. Yet somehow it feels incredibly isolating to see so much more out there and know not just that we cannot visit it, but that it is forever beyond our reach. The Kurzgesagt staff managed to manufacture a deep sense of desolation and despair. Impressive. Thanks.
eh, who knows, maybe in 100 thousand years we will be able to generate gravity and will be able to lasso the universe back together?
There is a theory that that will happen naturally but when it gets pulled back it basically squishes together and then forms another big bang. Its called the big bounce.

We must preserve it and keep it safe for future species!" Oh, Universe! So beautiful and scary. You are so much darker, mysterious and bountiful than any religion could be to me. I hope we never stop learning from you, terrifying though you are.

Theoretically, for example, the Harry Potter universe has magic. But the magic is quite tightly codified, and that's how we can take it seriously. If Dumbledore summons a phoenix, it's within the bounds of established reality. If Dumbledore collapses the local cluster and turns it into butterflies, that would destroy the fabric of the fiction itself.
Obviously you can write a work in which everything can be done, like "and just like that, John leapt to the edge of the observable universe". But you'd be hard-pressed to have anyone take your 'fiction' any seriously than we do random ramblings.
@@Muircetach Depends...
@@Muircetach To achieve reader believability while breaking a limit, there are several ways of doing this.
(1) Distract the reader with more pressing matters; a plot, a threat, survival, just anything urgent or compelling will do,
(2) Just break one limit and keep the rest; for example, just because a futuristic starship can travel instantly travel millions of light years in an instant, does not mean it can time travel or create energy out of thin air, both of which are arguably more difficult, or
(3) Incur a cost or penalty; in Back to the Future, the Delorean originally requires Plutonium to power; Voldemort has to tear apart his soul to achieve immortality, or at least the fantasy of it.
In short, there is not really any limits in fiction, or to put it in a more conservative manner, you can set the limits just enough for whatever it is you need it for, so long as you are creative enough to frame it in a way that is logical and believable.
Accually, there exist something human cannot imagine or describe.

Nop.... never gonna happen, we will never achieve speed of light (actually talking about EM wave in general). Our atoms are even bound by EM wave which hold nucleus and electrons together. At speed of light, in simple words, it might disintegrate. To make it worse, the universe expanding not at speed of light......even greater than that because the space is expanding (Note: its not that they are moving greater than speed of light)
I like to think that the more we learn about how the universe works, and the more we develop our technology and awareness, we'll find that our limits will continue to be broken. It could be only a matter of time before we discover interstellar travel that will make traveling vast distances possible even if there are very sound reasons to think it's impossible.
And we spend our time screwing over and killing each other.... People need to get a grip and see the possibilities...

Good news! You'll be happy to know that we will ALWAYS know a lot, and still know nothing. Yes, in the last few centuries, we went from guesswork to educated guesswork (the Scientific Revolution) and have been doing a little better when it comes to forming an idea of how the world works, but the number of questions only ever seems to increase.

This raises some interesting philosophical questions about knowledge itself.
Would anyone really blame the Milkdromedans for thinking their cluster was the only one that existed? While we would know this is wrong, they would have no way of actually knowing so, and all evidence would support their conclusion that they are isolated. What I'm trying to say is that is it in fact possible to know the actual truth of anything? What we consider truth is based on what we observe, and what we observe can change over time, thus changing what we consider truth.
Daniel Olowu I was thinking the same thing while watching this. How do we know what actually happened in the beginning actually happened when evidence of what actually happened changes over time? This is so eye-opening
Congratulations you are now an agnostic!
Wait, the Milkdromedans wouldn't have evidence that they're isolated...What they have is an 'absence of evidence'. It's not the same thing
cogito ergo sum
lisa s what if we now lack some evidence that was vital to coming up with a better cosmos theory?

6:09 maybe there's something that we don't know and we will never know
Yeah, what if the universe as we know it today is actually in its own “pocket” separated even further from other “pockets?” What we think is the entire universe is only what we can detect, like what the Milkdromedans of the future will think the observable universe is just their supercluster.
@@samtherat6 I thought the same. But I think the difference is that we are currently able to see how the universe began, while the Milkdromedans wouldn’t
@@samtherat6 Exactly my thought. Maybe all of space is filled with pockets of matter, endlessly. There is no way to know with conventionell technology (bound by lightspeed).
And if you think further, what if the fastening expension of the observeable universe is caused by the gravity of these other universe pockets which are possibly masswise statisticly even distributed around our observeable universe in the longrun. So Einstein was right with dark matter beeing the biggest blunder in his carreer.
Yup, I definitely believe so... We wouldn't know what major secret may be missing that would make us have the rewrite the entire history of the universe...
Maybe someday we can use dark energy to create something on our own

What if advanced aliens haven't contacted us because we are one of the last primitive planet in the universe and they are preserving us like we do the uncontacted tribes
Than consider yourself lucky. Ignorance is bliss
They were getting ready to contact us until they picked up an episode of keeping up with the kardashians in their ship
There is no way for "advanced aliens" to even know that we exist unless they live within 200 lightyears of reach from earth (which is unlikely to say the least).
Well, we were advanced enough for aliens to come here and actually say hello until they saw the presidential debate
But we did contact the uncivilized tribes lol. We killed them after robbed them. So why do we think that the advanced aliens will be nice to us?

The common assumption in cosmology that that there are parts of the universe that we cannot see. It is currently believed that the early universe expanded so fast that the light from most of it has not reached us yet.
I would add that most of our knowledge on the universe is very recent and dark energy was only discovered around the year 2000. We should conclude that our views of the universe will still undergo drastic changes in the coming decades and centuries.
So if in the distant future, the observable universe will only be our local group, and it will appear as an isolated static system with no way to show otherwise... is it possible that an analogous illusion is being played on us right now? Like that we are in a larger, static universe, but some event caused an expansion of our local pocket (the observable universe) , leading us to incorrectly deduce the big bang and stuff?
For the record, I believe in the big bang as strongly as I believe in anything. Just curious, that's all.
Yea, its very possible, we just use the information we have as of right now to make predictions. That's another reason why we say the "observable" universe, because it could be so much bigger than we actually know
Try Twice Like mice not yet but it gets faster by the second
But technically yes it maybe
It is possible, we would have know way to know one way or the other, so we just assume what we see is the origin because for us it effectively is irrespective of anything that could've come before.
If you think about it everything is so small. I mean we look at bacteria and say those things are microscopic but maybe some being out there just looks at the universe like that thing is so small. Idk Bruh shit be wild
Imagine living in a civilization where you think you're just a single galaxy in the middle of an endless void, people would theorise whether or not there's more places out there, though noone would ever be able to prove it.
*no one
Its not noone lol
@@delicatepath2923 Noone cares
@@jgsh8062 *no one
We already live in the middle of an endless void. Since we are the observers, we are in the middle, and beyond the limit of observable light, there is only what we could call "void" at least not in a technical meaning. So it doesn't change that much. That logic goes further if you think that is not that easy to visit even our moon... Or planets in our solar system*.
