Yes they are very good at crafting narratives, quite useful for globalist propaganda purposes! That's what this channel is by the way, a psy-op, willingly or unwillingly (they have to be fully aware at this point).
One of the most harrowing and humbling facts about the far future is that once you get to a certain point, it really doesn't matter what units you're measuring time in. When you get to numbers like 10 to the power of 1500, it's so ridiculously large that you could measure it in anything from microseconds to star lifespans and you'd get roughly the same amount of time. So when they say "a time so absurd it has no name" they're not kidding around, measuring it is irrelevant
@@vii-ka Take the example of when the universe is supposed to reach its final energy state, in total thermal equilibrium. Should happen in around 10^10^120 years, but on timescales that vast it wouldn't matter if that number were seconds, Planck times, years, decades, etc. Same with when a new big bang could occur due to the probabilities of quantum fluctuations happening on infinite timescales, that number is 10^10^10^56 and it doesn't matter if it's Planck times, years, minutes, centuries, etc.
Star lifespans can be as long as 10 trillion years for the hardiest red dwarfs, much longer than the current age of the universe. Of course that all becomes a non-factor once you get far enough. In fact, on timescales long enough to lead to iron stars, the subsequent destruction of the resulting black hole is instantaneous
@@fordid42 ah ya so saying 10^10^10^s but in another time unit it would be 10^((10^10^s)+1).. our estimates are not even that specific so there is no distinction.. i guess i kinda maybe got it in my reply? minimal or negligible difference between time units
I think it’s referring to the big bang and the last implosion parallels. The Big Bang happened absurdly fast, and the final implosion happened incomprehensibly fast.
You are looking at it from our perspective. Perhaps when you look at it from the perspective of the universe as a whole, it doesn't seem to be so long. A fly can live for up to a month, while most healthy humans can live to be 85 -100 years old. To a fly, 90 years would seem like 1000.
I remember when I was younger, like from 10-18 or 19 years old, I would get this indescribable feeling when thinking about how big and old the universe was and how tiny and insignificant people are in comparison. I would only feel it if I was somewhere where I could look up at the stars, but the closest I can come to explaining this feeling was a sense of a calm feeling of understanding something mixed with some bits of like loneliness and sadness. It stopped happening as I got older but I still remember having these moments of just trying to think about the whole size and scope of the universe and my brain just having a complete emotional overload at the attempt... I'm sure there is some word in German to describe this exact sensation.
What do you call it when you remember that it's fucking weird that anything exists at all when presumably non-existence is simpler and more reasonable to expect than a universe with spatial dimensions, time, matter, energy, consistent physics, and logic/mathematics.
So many people tall about existential dread and angst. Personally for me, this channel has been teaching me about existential humility. In many ways, it also helped me deal with anxiety. Because no need to worry too much when you realize that you're just that insignificant.
Its excellent for anxiety, but also don't let it spiral into depression tho! You must use your time in this universe for you! Make your experience a great one, and leave this place better than when you joined it (so that those who will come after can also have a delightful and wonderous journey.) ✨️
I felt the same! We're so insignificant compared to the majesty of the Universe. One day everything we know will not exist anymore, so today we have the opportunity to do the thing we love, doing our best and giving priority to the things that really matter. ❤
I can't believe Kurzgesagt is putting out videos so quickly now. This is legitimately premium content. Thank you for your contribution to learning for everyone!
I honestly love how there’s a whole story in this video with the passengers of the Spacetime Tours ship progressively getting more and more deranged and upset as they spend more and more time inside the spaceship and their mental health slowly deteriorate
I pretty certain they went insane as the years went by. In a short part of the vid, one of them wanted a refund but there is no one alive for a refund. This is why immortality would be a terrible.
I love how you guys always spend like ten minutes inducing an existential crisis in all of us and then hit us with "But you don't need to worry about that for a while :)" right at the end 😂
It's important to remember when discussing these topics. All of humanity has been a blink of an eye compared to these events. It's silly to worry about events that will take trillions and trillions of years to happen. Assuming we're even correct with our theories.
@@PsRohrbaugh If we're wrong, or if it were to happen tomorrow, it's still silly to be worried - it's not like there's anything we can do about it - individually or collectively.
For anyone having an existential crisis over this, here's something to think about: Some astrophysicists have pointed out that the state of the universe after heat death (all matter and energy being equal, concepts of space and time being meaningless) is actually similar to what, for lack of a better word, "existed" before the Big Bang. In other words, our universe will die, but in the process it might just give birth to the next universe. I think there's a bit of comfort in that possibility.
The description of electrons like passengers on a train is actually a surprisingly good one that also works for explaining stuff like the conductivity of metals and the photovoltaic effect.
I always remember the last words from another video that exactly described the same thing as here, the end of the universe: "Someday, nothing will happen... and it keep not happening, forever". That line gives me the chills every time.
I love knowing that Kurzgesagt is one of the larger youtube channels. It is well deserved and I love knowing there are so many people out there who love to learn about science, our place in the universe, and enjoy the feeling of curiosity and learning.
Only influence is topics in the sense that if they agree with the topic the sponsor can sponsor the video. They have no say in the content. They have a contract for a reason. @@ppeez
seriously, kurzgesagt always make things that are hard to grasp easy to understand. good job kurzgesagt, you're not just simplify something but also re-explained in the way most of us understand
Kurzgesagt is just so fun to watch. As an astrophysicist studying black holes, the way such easy to understand scientific communication is carried out through good research, animations with stories and characters, and with the help of the community, your channel has consistently inspired me to better myself with communicating science and its core philosophies (with the child-like wonder intact). I've been here since day 1 and I'd like to appreciate Steve Taylor - the signature voice and vibe of this channel! Although I always see comments on the team's work which is in itself commendable, let's not forget the world in which Steve sends us through his voice with each remarkable video. Keep being awesome Kurzgesagt, and keep making amazing content that is true to its work and open for rectifications if necessary!! This is what science is about, we must keep wondering. P.S. If you ever need to hire I'm up for the job 😉
I remember the last video about interstellar war where steve taylor had to say an extremely long number. It was describing an object moving very close to the speed of light and it was something like 9.9999... followed by like 10 nines. It was so funny and he struggled so much, and he even "phewed" at the end of it. I don't think the "phew" was even in the script, I think it was just that much of a struggle lmao. It has to be one of my favorite kurzgesagt narrator moments so far.
Thank you for this. You’ve spoken for many of us… most of which, including myself is not academically a scientist, but still possess the curiosity & passion for individual research! Amazing video. I’ll ignore my existential dread (still thrilling!) after watching this. 🙌🏽👍🏽
I have a question for you. I am not a physicists and i could not do the math with a gun to my head, However my personal hobby has been black holes since i was a kid and they were still widely theoretical. I just had a thought recently about pancakeification. First a black holes gravity would cause spegghetification because of gravitational waves, but what if because of time dialation the particles can go no further than the event horizon, and instead create a plank shell of matter. this plank shell houses a sort of vacuum of dark energy and as the shell grows as more matter falls in and adds to the shell, the dark energy grows. Hawking radiation forms near the event horizon, negative mass particles fall in and create small gaps that last only fractions of a second, but are drawn out by time dilatation, adding non gravity effected dark energy to the universe? Just a thought i had, probably crazy and un-scientific. Wanted to run it past someone in the community.
are you in progress studying or do you have your degree? I remember doing this in my science degree and this seems like its missing some things, like the fact that we dont know the direction the expansion of the universe will inevitably take, IE big freeze, rip or crunch. we dont even know if crunch would by cyclic, the universe could just keep being reborn, if thats the way, then maybe we arent the first iteration of the universe. also hawking radiation emits photons, if this is right and the universe goes for big freeze then the photons also will be dispersed and eventually quantum fluctuations would result in collisions which would have mass and thus gravity and eventually with enough time would combine enough and collide together to create new stuff ext. either way there are so many assumptions in all of this I feel like we cant really say "this will be the last thing in the universe" though still interesting. feel free to correct me.
Just the very concept of atomic scale mini reactions, caused by extremely weird and rare occurences, taking place in a dark and empty void over a time scale so inconcievable it completely overshadows time scales that are already inconceivable and eventually causing a massive supernova that lights up the universe for one final time is genuinely breathtaking to me
@@d00mnoodle yes but there will be one last one allthough imagine that SOMEHOW multiple supernova remnants have bounded together to make one last pseudo black dwarf wich explodes again? lol also they completly ignored the expansion of the universe, before ANY of that the universe will have expanded soo much that the weak force holding the atoms breaks and all matter ceases to exist on the current form
@@fallenstar171 i'm no physicist, but my gut feeling tells me that the whole black dwarf would be moving away from the universe's center when the universe expands. And not necesarily the black dwarf itself disintegrating because it expands outward. But correct me if i'm wrong, i have no proof of this and it's just something that seems likely to me.
@@d00mnoodleisn’t current theory that the universe has no centre, since when we looked at several different points, everything was moving away from them or something like that?
Wasn't that due to red/ blue shift? Where the light waves lengthen/ shorten as they move away from us (the same as a race car's engine noise distorts as it goes past you). I'm not sure if current science thinks the universe has a center or not, I just know that this phenomena is another thing that affects... stuff.@@kooskoos1234
When I heard about KiwiCo on your channel, I thought, "I need that!" I am an 11 year old who is interested in astrophysics and engineering. I bought the robot that puts stuff in its mouth and built it. Best thing ever. Thank your kurzgesagt. I love your videos and channel and everything about it. Your voice for example is not annoying to hear or listen too, it is calm, soothing, and smooth. The animations are too. This is stuff my school struggled to teach me, yet I am the only kid in my school who knows the last thing that will happen in the universe. So I end this paragraph, with a thank you.
I struggled in school when I was your age too. Teachers didn’t teach in ways I was able to learn. I went back to school after leaving for a long time because I wanted to do something better for myself. Keep going, keep up the good work, and I applaud your childlike wonder. Even when you grow up and have to pay taxes and stuff, I hope you never lose that sense of curiosity and wonder. May your mind be free of those dark clouds that fog so many of us these days, and may you always look towards the stars for answers. ❤
@@krystalreverb Dark clouds indeed. I miss the carefree, responsibility-less days of my youth. The vivid colors of life slowly fade to a drab grey for most of us, but I hope this kid follows his interests and finds happiness and purpose.
Can’t believe they really locked 3 birds in a spaceship for all eternity and let them loose their minds just to find out what the last thing to ever happen is.
This really puts into perspective the notion of "old age" that we are used to. Someone living until 100 years or historical event having taken place 1000 years ago always seems a lot. And that shows how brief our existence is. Our lives are ridiculously short on the scale of the universe. It's as if we never even happened.
it’s so weird to think about, I can hardly even comprehend or wrap my head around just like… nothing existing. It really is hard to imagine such a thing happening so long from now
You didn't exist before you were born. You also won't exist after you go. The only thing left is your footprint, in a tiny rock, floating in space surrounded by more tiny rocks. Nothing matters, life is short, let's watch TV.
@cozyrecords256 not in this universe, it seems like everything is accelerating away from each other, so the universe will just be cold and dark, just like our stupid bodies after we die.
I can't be the only person who's glad that I have this sense of universal awareness. To be able to contemplate these stuff every time I look up the night sky is something I will be forever grateful for.
Your definitely not the only one that ponders this. I do all the time, not only when I look at the stars at night but especially when I look at the stars at night
Having gratitude towards an awareness greater than yourself is such a gift to feel. It's so nice that, despite how limited our perspective is, we are able to partake even minimally in something so awesome
@@briangrosenbach Ironically this might make US the greatest and most awesome thing in a fantastic but possibly otherwise lifeless universe. We might be the only product of this universe capable of marveling at it.
yeah they are punished to be immortal and stuck in their space station jail forever, cant die and their space station is more immortal than black hole and black dwarf or proton lol we can say they live longer than black hole and black dwarf 😂
Wow, this is mind-blowing stuff! The thought of a universe slowly extinguishing itself over billions of years is indeed humbling, isn't it? But it's comforting to know that we're still in the exciting phase of the universe's life. Thanks for this deep dive into cosmic evolution. It really puts our existence into perspective.
Universe had a beginning it will have an End as well. And if We analyse History then its easy to realise that there isn't a SINGLE civilization in human History which hasn't been destroyed / punished / annihilated for their disobedience and sins. Be it - Babylonian, Mesopotamian, Indus Valley civilization, Persian, Roman, Assyrian, etc. etc. However, there are probably people who think that this Technologically Advanced Modern Civilization could be an exception. We all can just wait to see or Prepare! This is the Order of Events according to my limited knowledge & understanding (I can elaborate much more but I tried to be as concise as possible) :- Collapse of Petro-dollar, Paper monetary system [(actual cause of WW3), many geo-political conflicts and situations are side reasons /smoke and mirrors] ~ 80% - 90% expected to die ~ Many years of great oppression & injustice, more than even now (probably 7) ~ lsraeI ruling state of the World (obvious) ~ Emergence of Mahdi (r.a.) - A Guided & Just ruler ~ Peace & Prosperity for a while ~ Coming of Dajjal/Antíchrist (their much awaited one-eyed Messiah) in Human form (live for 37 days & will do many miracles & many things) ~ coming of Eesa/Jesus (p.b.u.h.) & killing Dajjal ~ Peace for many years (some say 8-9 years & some 40) ~ Coming of Yajuj and Majuj (a corrupt ancient tribe) in large numbers & much violence & killing ~ Their destruction from an infection / disease on their neck by Allah s.w.t. ~ Peaceful death of all the believers from a breeze from Yemen ~ Destruction of the Kaaba 🕋 (in Mecca, Saudi Arabia) brick to brick by Dhul suwaq qatain (a person with short legs) ~ Dwelling of only Disbelievers and Criminals on Earth ~ The Earth will be cursed coz there will be no one to say La ilaha il Allah (There's no God except Allah) ~ Trembling of Mountains & shaking of the Earth (physical destruction of the World and the Universe). We have been already warned about it! And there is no city but that We will destroy it before the Day of Resurrection or punish it with a severe punishment. That has ever been in the Register inscribed. [Chapter 17 Isra (The Night Journey) : 58] 'That they said (in boast), "We killed Christ Jesus the son of Mary, the Messenger of Allah";- but they killed him not, nor crucified him, but so it was made to appear to them, and those who differ therein are full of doubts, with no (certain) knowledge, but only conjecture to follow, for of a surety they killed him not.' Quran: Chapter 4 An-Nisa (Women), Verse 157.
I love how even kurzgesagt recognizes how dreadful this topic is and how big of an existential crisis it can give to young space enthusiast that they have to also squeeze in a 1 minute long therapy session at the end lol.
Their stated position is positive nihilism which is essentially that it's great that everything exists, that anything exists, that we exist, and we should find our own meaning and enjoyment to make it worthwhile. If you feel dread at the realization of the transitory nature of all things before time and entropy then you're admitting reality is too much for your feeble mind and that you're too weak willed to face it - the universe has offered us a seemingly impossible challenge and while this is very likely the inevitable fate of the universe there is still much we do not know.
@@helloyes2288 No need for name-calling, but youre right that indeed, even within the cooling scenario, the percentage of what we know about 'how it happened'... is very small, not to mention the 'why'
@@sporovid5856 Fraser Cain has entered the chat. lol. Love Isaacs work though, his Civilizations at the end of Time and his Fermi Paradox series are among my favorite.
Is it weird that I was low-key terrified of vacuum decay, right up until I watched this? Now, all of a sudden, the prospect of vacuum decay randomly and spontaneously setting the universe ablaze no longer feels like a horrifying annihilator - but a universe-wide reset-button, potentially allowing something new to flourish once again.
and the best thing is, if we're correct in our understanding of vacuum decay, and if the uncertainty principle isnt proven wrong, vacuum decay is GUARANTEED to happen over the long and slow death of our current universe. Infinity is a long time for anything to happen, after all.
@@offensivequandal6334at that point, though, considering how unlikely it already is, and using this to roughly calculate when it would be inevitable to occur, everything in the universe would be so far apart that it might not ever collide with anything, and this is already assuming that there is anything of note left in the universe when it finally happens. Which is terrifying once you compare Vacuum Decay to how our universe supposedly came from…
@@apollyonnoctis1291 You see as the universe endlessly expands past the point of no return the speed of light. Don't you see the endless cycle. This new supernova of a black dwarf could create a new universal constant. We might all be localized environments due to a single black dwarf from a universe that died long before us. The expansion of space that happens faster than even light itself may be a reflection on that as our previous big bang the OG supernova of a black dwarf may had at a time been a star in a much larger system that is now impossible to observe
@@apollyonnoctis1291 the extent at which the vacuum decay will encompass does not need to wash over remaining matter. all it needs is to well, happen. then we enter the realm of the unknown as we dont know what a truly stable higgs field looks like. and even then the vacuum decay WILL wash over remaining matter. this is because of entropy and the law of conservation of energy. mass and energy cannot be destroyed nor created, only altered, and in the process of heat death, energy and mass will remain, however in unusuable forms, kind of like vhs loss where if the tape is copied over and over, it eventually turns into static. however the original content is still there, the building blocks are still there, and vacuum decay will wash over these building blocks, it is just a matter of when
I think it's amazing to live at a period of time in wich with a click I cant know how everything's gonna end and almost know everything I'm capable to understand. It's amazing and breathtaking and I love that there's peaople like you maing this videos for all of us to enjoy. Thank you so much for this!!
I hope we're not the only intelligent civilization to study this. And others are traveling through the vastness of space to find and connect with other civilizations. Regardless, the fact that humanity question the border of space and the beginning and ending of all these things are both mind-blowing and deeply scary.
It's actually quite fascinating to think about: We exist close enough to the literal start of _everything,_ that we can partially still observe the direct aftermath and all stages between _then_ and _now._ Our understanding of physics and the universe is so big, we have a guess at what will happen in a future so distant, that we can't even abstractly understand just how utterly insanely far away it actually is beyond "it's a _really_ long time until then". The entire human existence is like a grain of sand in a desert compared to the current age of the universe. The universe's current age is a grain of sand in the desert to the time, it'll take for all matter to turn into black holes, neutron stars or white dwarfs. The time until that happens is like a grain of sand in the desert to the time it'll take for black holes to evaporate and white dwarfs to become black dwarfs... and all that time is still just a grain of sand in a vast desert to what might happen thereafter (if our understanding of all this is correct). There is a time in a (not nearly as distant but still) far out future, long after Andromeda and the Milky Way have merged, when sentient life will look at the skies and see nothing that's not directly in their own neighborhood. All lights in the sky will be contained within their own galaxy. The background radiation, that allows us to analyse the big bang, will have become indistinguishable from background noise. All other galaxies will have moved beyond the range in which their light is able to outrun the universe's expansion. Those lifeforms will not be able to understand how the universe was formed, they won't know that there's other galaxies out there (and even if they did, it'd be functionally meaningless to them) and they would see barely any new stars forming, maybe not even see old ones dying, given that most stars will be long-lived ones, that'll still take an absurd amount of time to run out their fuel. It's mind blowing to think that we live in a time, where we can look at *_both the possible start and end of the universe_* and that there's a time in between when sentient life will have absolutely _no means_ to do the same. To them, the universe will be entirely static and appear to be eternal and unchanging both in the past and future.
Another thing to note is that humans are super young relative to even the creation of the Earth, which itself is extremely young. Humans compared to the universe have been around for practically zero time, yet we’ve already managed to advance to the point where we could end our own existence within 12 hours at any given time. Humans really are the masters of destruction. I truly wonder if there is any other civilization in the universe that can rival our destructive capabilities. And the fact that we use it all on ourselves if the funny part. We were just born to fight, kill, and hate each other.
@@SJ-di5zu Sometimes, humanity seems bleak, keep in mind we also created arts, philosophy and science that allows, for instance, us two strangers to communicate across the globe in real time.
@@SJ-di5zu I think that the ability to utterly annihilate itself is necessary for a civilization. Meaning that no matter what Aliens exist, if there technology advances at one point they will be able to annihilate themselves. Almost all predatory animals and a lot of non predatory animals kill each other in fights for territory or food or mates. We really aren't special in that way, only that other animals use primitive weaponry like teeth or claws (like our far ancestors used to) but we now, as a necessary side effect of an industrialized globe spanning civilization, have the ability to cause far greater destruction.
its just a chemical reaction. it doesn't have a will of its own or anything, which would be necessary for me to call it an inspiring fight. but you do you! your story is also nice
One of the best things about this TH-cam channel is that it gives science backed information which isn't normally accessible, breaks it down to a level where almost anyone can understand, constantly updates us with new research, and gives it to the public for free. Thank you for what you do, Kurzgesagt!
@@JesusPlsSaveMe prove it. But don’t say the Bible because anyone could write a book and say “i am god and this book proves it” and it would be just as valid
God according to abrahamic religions as islam and christianity and judaism prove that God will make us the humans to choose our path to hell or heaven@@The-one-and-only-Fruitcake
First of all, this was one interesting clip. Second of all, I watched this twice - one time for the actual spoken content, and one time just to follow the hilarious animated storyline. As usual - great work!
I just wanna say that your artstyle is amazing, it’s simple, but not too simple, I want like every one of your posters, the colors all pop, and your animations feel so smooth and satisfying, I could never do anything like that.
Isn't it fascinating to think that this might be how our universe was birthed? Who knows, there might have been another universe before us that ended like this
@@blobfishboy8678actually, no one knows the answer. In order to science to disagree, it needs a proof. It might not have been Jesus, but perhaps a God could have created the universe, nothing comes from nothing, and that IS one thing that science can prove.
@@madblox5094so it’s more believable that an omnipotent being decided to make everything exist? Your own argument undermines your claim: we have no proof that god existed so why should I believe you? We have much more proof that the universe came to be with the Big Bang.
I love how this episode combines theories explained before and adding more dimension to them. These videos have made me think about these things more thoughtfully and it's nice to see how they hold up against our current understanding of it all. I love you guys, you are absolutely amazing!
That's an incredible explanation of electron degeneracy pressure. The metaphor allows anyone to understand it! Amazing work once again. It is not easy to make complex physics ideas accessible to everyone.
How amazing is it that you get to be one of the very few particle bundles that is fully aware and can partially understand this beautiful thing we participate on that is the universe?
I mean, if we weren't, we wouldn't be able to notice it, so it kinda HAS to be this way? In order for something to be observed, the observer has to exist, therefore nothing can exist without an observer.
The only thing that matters is that you feel something. For a ridiculously short period of time called life, you feel something. Let that feeling be good, do things that fulfill you. Don't be stoped by other people an their "laws" and "ethicity". You are free and no one can stop you
Watching these videos give me a mix of existential dread about the end, and a FOMO because I won't live long enough to see how it plays out. Idk why this combo is such a vibe.
Kurzgesagt should be integrated into every curriculum. It's arguably one of the greatest and most approachable resources for education ever made. And it's damn gorgeous.
9:05 This is a great video, and I love how you put 3 misspelled versions of your team’s name before you got it right. How the word is misspelled shows that the person typing it got a bit frustrated trying to correctly spell it. The amount of detail put into every second of these videos is incredible, considering only a few people might notice any particular thing. All of these little details make these videos so much more full (or in this case, deVOID) of life! Keep up making such great content, it’s truly inspiring!
An idea expressed in an earlier Kurzgesagt video was that the universe could theoretically have died and been born again multiple times. Could the gravity of the matter emitted by the hawking radiation eventually pull all the matter in the universe into one big ball that causes the next big bang?
Stumbled across this comment right after learning about the Buddhist understanding of what causes rebirth and reincarnation (the ideas of Bhava and Vibhava) so this is blowing my mind.
Apparently there's been consideration of an alternative to the big bang, it's known as the big bounce model. It's still under review since it got brought up recently in '17.
Lets say big bang comes in cycles is true. Why does it do that? Shouldnt it reach equalibrium and stay as a singularity? Does conscience have a part in it?

Ain't gonna lie, every time I think about the very end, it terrifies me and gives me a huge anxiety attack. My mind is petrified of the thought of it despite knowing we won't be around to witness it. I find it a challenge to overcome the anxiety it gives me and I don't think I can ever overcome the thought of it.
No need to worry. We are control of nothing. Enjoy living this life is all we can try to do. Nature is ultimately in control and supreme above all else so in my opinion it is unnecessary to worry about anything that far into the future. There’s enough to worry about in life without this. Just relax and let things happen
We call this empathy, You woring about the future of others, it all matter, you're a good soul, who knows this is how our universe is born and it maybe what the nextone will be aswell.
Bruh why tf are you worried about stuff that your great great 10000x grandchildren don't have to worry about? Worry about yourself and your own life. There is far more you can do to improve yourself, rather than worrying about being an atom on a spec of dust in the cosmic desert of our universe
This video is truly a mind-blowing journey through the later stages of the universe's life. The concept of the universe's eventual death, as unsettling as it is, is presented in a very engaging and comprehensive way. The illustrations are just as captivating as the narrative, making complex scientific concepts accessible and enjoyable to learn about. Can't wait to see Kurzgesagt comes up with next!
There are theories that maybe it still wont be an end! Some time later even the protons, and neutrons will decay, so there will be no atoms anymore, but there will be a lot of neutrinos! Those are only very weakly interacting with each other, but it is possible(at least it can be calculated) for them to be bound to each other. The problem is, that the bond is weak, basicly the universe is too "hot", there are too much momemtum of the particles for it, and the calculated size of that neutrino "atom" would be bigger than the current universe. BUT, the universe is infinitely expanding, and in the process cooling, so there could be a time when the universe will be big and cool enough for a neutrino atom. From then on, with those there could be other structures, maybe like planets or stars based on neutrinos, so the universe will live again!
This is one of my favourite videos from this channel - and that's saying a lot! So well explained and animated. I don't know what I'd do without these videos popping up and making the existential crises seem irrelevant. Thanks Kurzgesagt!
Outer Wilds already helped me process all of this, and I've accepted it. Even if my life ends long before anything else in the universe happens, I'm glad I existed in it.
There are so many hidden details in this one, like how the density of a black hole displays strange symbols at first, before resolving into "ERROR - Calculation Failure" (2:38)
7:17 _"The difference between a second and trillions of years has lost all meaning"_ There's a quote for the ages! (eons?) Imagine learning galactic timescale is so mind boggling long, only to be told that THIS makes that look like child's play!
I remember a scientist discussing a possible connection between heat death and the big bang theory. I'm horribly mangling it, but I remember it went something like: When entropy reaches its highest possible state universally, all black holes have evaporated and all matter has degenerated into energy, there can no longer be any measurement of time or distance. At that point, the fully expanded and cooled universe could just as easily be considered a singularity from a different perspective which could in turn result in a new big bang. Since any intervening time or scale is irrelevant at that point, the only thing that matters is for the potential to be above 0, and since it supposedly happened once already, the potential is already above 0. The main issue I find with this idea is Planck's constant (assuming it remains constant at this scale) and the various flow-on effects that may have. But then, we have no reason to assume any possible future or past big bang's would have to follow the same development path ours did anyway. Anyway, my point is: The last thing that will ever happen might also be the first thing that will ever happen, from a different point of view.
That’s very interesting. Does this suggest that, without the constraint of time, anything with a probability greater than 0 would eventually happen? I’ve wondered this before, but it was explained to me that despite unlimited time, something with a probability that infinitely approaches zero (but does not equal 0) may still never happen. It bummed me out because I thought I was on to something.
@@MrMan-sy4ev Good question. I have no idea. On the bright side I found the hypothesis: Conformal Cyclic Cosmology by Sir Roger Penrose. I remember seeing an interview with him on the subject, but can't seem to find it now. Looks like PBS Space Time did a video on it: "What Happens After the Universe Ends?" Hopefully it would have some extra detail and will check it out myself after work.
@@MrMan-sy4ev If I were to roll an honest 6 sided dice 10 times, and rolled a 1 each time, what is the probability that the 11th roll will be a 1? It is 1 in 6. It is not more or less likely than any other time. So the quantum tunneling is very... very unlikely. But not so unlikely that it would not happen. The entire earth spontainiously jumping a lightyear is much... much less likely. It will never happen.
@@d.n.3652 Well for one thing, what may not be a big deal to you, may be pretty impactful to others, so don't judge. Secondly, it's more about feeling utterly tiny and insignificant when compared to the vastness of all that time. I mean, my lifespan is already insignificant when compared to the current age of the universe, and if the age of the universe is insignificant when compared to how long it's gonna be around, where does that leave me?

If you want to, watch Timeline of the Future, its basically this video but on steroids further delved in, that one gave me a big existential crisis about this topic, so I was kinda immune
Neil DeGrasse Tyson's "StarTalk" discussed the possibility of going through black holes to white hole big bangs in another energy rich universe, and adapting to it's physics. Existential crisis solved.
@@Elitaria If you don't like Neil, do you like Discover magazine? The article titled "Conquering Maxwell's Demon" discusses how a massive supercomputer could reverse entropy...hypothetically.
The ending really gave me chills... No matter how far away it is, expertly woven story arc and brilliantly performed (narrator and animation in point as ever!). I love you guys, never stop doing your thing!
If we perceived 100 million years per yoctosecond (Yoctosecond 1,000,000,000,000,000,000,000,000 = 1 second. It'd be no different than our current situation. In this imaginary perception of time, it will still takes soooo long before that happen
Why did it give you chills? The last thing that ever happens in this universe, this supernova discussed in the video by a collapsing black dwarf. Is merely the next big bang that restarts the next universe. See nothing to fear here at all. It's simply the same thing that has already happened countless times and will continue to happen countless more. Everything is as it has always been and always will be. There, feel better now?
Guys, if something is giving me chills, it doesn't necessitate that i am afraid of experiencing it for real 😅 why would I think that? As stated: the narration and presentation conveyed an eerie feeling that really took me along for the fictional ride. And I applaud the minds that created this video.
the universe will never end bc for something to end is for something to have been which is impossible once the universe ends bc nothing will ever have been bc there’s is no time or space or anything that ever is therefore was
Most people here describe how calming it is for them to understand the true insignificance of existence. But, somehow, I just feel so sad knowing eventually everything will cease, forever. Even the tiniest change or effect will amount to the same as if it never happened. And pessimistic as I may be at times, I care too much for the world to see it end.
By the way many great minds (scientists not philosophers) consider that we don't know so much more than we do know, that the story here is most likely is not true. One famous example is Penrose who won a Nobel Prize recently. One of his theories suggests that the end of the universe depicted here is mathematically equivalent to the first moment in the universe, that is big bang. Read about it and other theories, and be optimistic, life is so much more than we know, and it is quite ignorant of us to imagine that we know enough
I started watching your videos cause I found your book about the immune system in my local library and was in awe and in love. Please publish more books!
the final supernova was made so beautifully (with soundtrack and narration and everything ), I felt a sentient flow that made me feel like crying 😢 it's like an epilogue of an orchestra, or a farewell to all the wonderful thing's that has ever happened.
Little bonus for the curious: the same quantum effect is expected to turn every object in the univers (lonely planets, asteroids, Voyager 1, dust, etc.) to pure iron on scale of time absolutely enormous. But those object, because they aren't degenerate, won't explode. Instead, on a timescale bigger still, every atom will quantum tunneling to theirs center and ultimately create a small black hole that will eat the rest before evaporating in the blink of an eye.
“When the first living thing existed, I was there waiting. When the last living thing dies, my job will be finished. I'll put the chairs on the tables, turn out the lights and lock the universe behind me when I leave.” ― Death, Neil Gaiman, The Sandman, Vol. 3: Dream Country
I wonder if she has to wait for that final bang (and that forever in between) or can she just see to the last ”living” thing and then either move on or kind of speed run the rest of the universe’s end? 🤔

@@wicketd2 The idea that entropy can increase in a closed system is based on an a system that can be open and closed on demand. Because if yo want to reduce the entropy of a system you have to interfere with that system from the outside. These systems are technically speaking not closed. A real closed system can't ever be opened from the outside. The only closed system that exists is our universe. The universe definitionally speaking contains everything. There is no thing to open it to. The entirety of the universe has no walls. It has no end. It is infinite in every way imaginable. This is why there is no end point, where you can theoretically add or subtract energy. There is no physical mechanism that would reduce entropy to the state before big bang supposedly happened. Meaning big bang is a misunderstanding of the evidence. The laws of thermodynamics demands that we need to live in what astronomers call heat death (more academic term is thermal equilibrium). There is a balance between all the forces of nature and the energy of the universe. It is like how a gas in an approximate closed system reaches an equilibrium, where all energy is evenly distributed, there will still be molecular structures that are forced in to exist. Molecular structures hinders the increase of entropy. This leads to most of space being empty. This is similar to how our laws of nature is obviously keeping most of the universe relatively empty. The fact that none has agreed on what causes our universe to take roughly the shape as it does now for ever doesn't make it less true. Ignoring the laws of thermodynamics comes with huge issues. The second law of thermodynamics is a statistical concept of cause and effect. You need to abandon the idea that things happen for a reason if you want to abandon the idea that our system can just randomly reduce in entropy on the astronomical scale needed for big bang.
This had a sort of melancholic and soul-touching beauty to it... a video and dialogue that has touched me in a way I haven't experienced since I first heard "Pale Blue Dot" Thank you, writers and narrator, for sharing this breathtaking piece of knowledge
i feel like when one universe dies, its quiet for a while, and then another big bang happens creating a new universe. i also think theres multiple universes alongside each other like galaxies living aside each other. it's mind blowing how infinite space really is.
I think people forget to realise the idea of the universe is a philosophy, its just everything as a whole, there is nothing outside of it our influencing it will always be unified, I think believing in its death is not believing in everything being universal defeating the idea of a unvierse
what? I think you misunderstood, I'm saying everything is whole, by saying these things such as a time and energy and so on defeats the purpose of the universe because there seperate entities and aren't universal time itself isn't a definite but a philosophy and the sooner we understand that the sooner well get to having an uncontradictory system in which the universe comes from nothing and then just turns into nothing defeating the idea of a universe @@felixstone3.14
My main problem with this theory is this- how do you define a single universe in a collection that are physically separated by space like that. The definition of the universe is that it’s everything in this space-time dimension, so by your logic those aren’t “universes”. But are instead relative and subjective sub-pockets limited by their own cosmic horizon
wow, i dont have a lick of an existential crisis when i watch these space videos. i feel comfort. like i know the universe is harsh and doesnt give a shit about us but still.
I had a nightmare one time when I was very young that felt very similar to being a black dwarf. I was aware that I existed but I had no ego. All I could experience in this dream was immense pressure from all around, and I felt like I was a super dense rock. Time was irrelevant and I felt stuck here for a long time. Quite an out of body experience for an 11 year old.
I had a dream around the same age where for some reason I had to hold up this giant stone pillar that reaches for miles into the sky, like Atlas or something... maybe there's some pattern behind these kinds of dreams...

Yes they are very good at crafting narratives, quite useful for globalist propaganda purposes! That's what this channel is by the way, a psy-op, willingly or unwillingly (they have to be fully aware at this point).
One of the most harrowing and humbling facts about the far future is that once you get to a certain point, it really doesn't matter what units you're measuring time in. When you get to numbers like 10 to the power of 1500, it's so ridiculously large that you could measure it in anything from microseconds to star lifespans and you'd get roughly the same amount of time. So when they say "a time so absurd it has no name" they're not kidding around, measuring it is irrelevant
millenia: 10^1500
years: 10^1503
like this? (also for some reason i at first typed h instead of 5)
@@vii-ka Take the example of when the universe is supposed to reach its final energy state, in total thermal equilibrium. Should happen in around 10^10^120 years, but on timescales that vast it wouldn't matter if that number were seconds, Planck times, years, decades, etc. Same with when a new big bang could occur due to the probabilities of quantum fluctuations happening on infinite timescales, that number is 10^10^10^56 and it doesn't matter if it's Planck times, years, minutes, centuries, etc.
Not even, nanoseconds to the universes lifetime.
Star lifespans can be as long as 10 trillion years for the hardiest red dwarfs, much longer than the current age of the universe. Of course that all becomes a non-factor once you get far enough. In fact, on timescales long enough to lead to iron stars, the subsequent destruction of the resulting black hole is instantaneous
@@fordid42 ah ya so saying 10^10^10^s but in another time unit it would be 10^((10^10^s)+1).. our estimates are not even that specific so there is no distinction..

You are looking at it from our perspective. Perhaps when you look at it from the perspective of the universe as a whole, it doesn't seem to be so long. A fly can live for up to a month, while most healthy humans can live to be 85 -100 years old. To a fly, 90 years would seem like 1000.
Yo
I remember when I was younger, like from 10-18 or 19 years old, I would get this indescribable feeling when thinking about how big and old the universe was and how tiny and insignificant people are in comparison. I would only feel it if I was somewhere where I could look up at the stars, but the closest I can come to explaining this feeling was a sense of a calm feeling of understanding something mixed with some bits of like loneliness and sadness. It stopped happening as I got older but I still remember having these moments of just trying to think about the whole size and scope of the universe and my brain just having a complete emotional overload at the attempt... I'm sure there is some word in German to describe this exact sensation.
I know this sensation you allude to. I wish more people would experience it. Might change a lot of perspectives.
I know what you want to say. But the word isn't simple, maybe awe?
What do you call it when you remember that it's fucking weird that anything exists at all when presumably non-existence is simpler and more reasonable to expect than a universe with spatial dimensions, time, matter, energy, consistent physics, and logic/mathematics.

So many people tall about existential dread and angst. Personally for me, this channel has been teaching me about existential humility. In many ways, it also helped me deal with anxiety. Because no need to worry too much when you realize that you're just that insignificant.
Its excellent for anxiety, but also don't let it spiral into depression tho!

For anyone having an existential crisis over this, here's something to think about: Some astrophysicists have pointed out that the state of the universe after heat death (all matter and energy being equal, concepts of space and time being meaningless) is actually similar to what, for lack of a better word, "existed" before the Big Bang. In other words, our universe will die, but in the process it might just give birth to the next universe. I think there's a bit of comfort in that possibility.
maybe that universe will get things right ;) and not be the same shit show we have on earth now :D
Existed before the big bang.
lol if you believe in the BB then there is no knowledge of what existed before..

Kurzgesagt is just so fun to watch. As an astrophysicist studying black holes, the way such easy to understand scientific communication is carried out through good research, animations with stories and characters, and with the help of the community, your channel has consistently inspired me to better myself with communicating science and its core philosophies (with the child-like wonder intact). I've been here since day 1 and I'd like to appreciate Steve Taylor - the signature voice and vibe of this channel! Although I always see comments on the team's work which is in itself commendable, let's not forget the world in which Steve sends us through his voice with each remarkable video. Keep being awesome Kurzgesagt, and keep making amazing content that is true to its work and open for rectifications if necessary!! This is what science is about, we must keep wondering.
P.S. If you ever need to hire I'm up for the job 😉
I remember the last video about interstellar war where steve taylor had to say an extremely long number. It was describing an object moving very close to the speed of light and it was something like 9.9999... followed by like 10 nines. It was so funny and he struggled so much, and he even "phewed" at the end of it. I don't think the "phew" was even in the script, I think it was just that much of a struggle lmao.
It has to be one of my favorite kurzgesagt narrator moments so far.

I just listen and disagree because scripture gets better looking women than science
I have a question for you. I am not a physicists and i could not do the math with a gun to my head, However my personal hobby has been black holes since i was a kid and they were still widely theoretical. I just had a thought recently about pancakeification. First a black holes gravity would cause spegghetification because of gravitational waves, but what if because of time dialation the particles can go no further than the event horizon, and instead create a plank shell of matter. this plank shell houses a sort of vacuum of dark energy and as the shell grows as more matter falls in and adds to the shell, the dark energy grows. Hawking radiation forms near the event horizon, negative mass particles fall in and create small gaps that last only fractions of a second, but are drawn out by time dilatation, adding non gravity effected dark energy to the universe? Just a thought i had, probably crazy and un-scientific. Wanted to run it past someone in the community.
are you in progress studying or do you have your degree? I remember doing this in my science degree and this seems like its missing some things, like the fact that we dont know the direction the expansion of the universe will inevitably take, IE big freeze, rip or crunch. we dont even know if crunch would by cyclic, the universe could just keep being reborn, if thats the way, then maybe we arent the first iteration of the universe.
also hawking radiation emits photons, if this is right and the universe goes for big freeze then the photons also will be dispersed and eventually quantum fluctuations would result in collisions which would have mass and thus gravity and eventually with enough time would combine enough and collide together to create new stuff ext.
either way there are so many assumptions in all of this I feel like we cant really say "this will be the last thing in the universe" though still interesting.
feel free to correct me.

Just the very concept of atomic scale mini reactions, caused by extremely weird and rare occurences, taking place in a dark and empty void over a time scale so inconcievable it completely overshadows time scales that are already inconceivable and eventually causing a massive supernova that lights up the universe for one final time is genuinely breathtaking to me
I assume multiple supernovae, since there will probably be many black dwarfs
@@d00mnoodle yes but there will be one last one
allthough imagine that SOMEHOW multiple supernova remnants have bounded together to make one last pseudo black dwarf wich explodes again? lol
also they completly ignored the expansion of the universe, before ANY of that the universe will have expanded soo much that the weak force holding the atoms breaks and all matter ceases to exist on the current form
@@fallenstar171 i'm no physicist, but my gut feeling tells me that the whole black dwarf would be moving away from the universe's center when the universe expands. And not necesarily the black dwarf itself disintegrating because it expands outward. But correct me if i'm wrong, i have no proof of this and it's just something that seems likely to me.
@@d00mnoodleisn’t current theory that the universe has no centre, since when we looked at several different points, everything was moving away from them or something like that?
Wasn't that due to red/ blue shift? Where the light waves lengthen/ shorten as they move away from us (the same as a race car's engine noise distorts as it goes past you). I'm not sure if current science thinks the universe has a center or not, I just know that this phenomena is another thing that affects... stuff.@@kooskoos1234
When I heard about KiwiCo on your channel, I thought, "I need that!" I am an 11 year old who is interested in astrophysics and engineering. I bought the robot that puts stuff in its mouth and built it. Best thing ever. Thank your kurzgesagt. I love your videos and channel and everything about it. Your voice for example is not annoying to hear or listen too, it is calm, soothing, and smooth. The animations are too. This is stuff my school struggled to teach me, yet I am the only kid in my school who knows the last thing that will happen in the universe. So I end this paragraph, with a thank you.
You're a very well-spoken 11 year old. Keep feeding those interests of yours and it will take you to some amazing places.
I struggled in school when I was your age too. Teachers didn’t teach in ways I was able to learn. I went back to school after leaving for a long time because I wanted to do something better for myself. Keep going, keep up the good work, and I applaud your childlike wonder. Even when you grow up and have to pay taxes and stuff, I hope you never lose that sense of curiosity and wonder. May your mind be free of those dark clouds that fog so many of us these days, and may you always look towards the stars for answers. ❤
@@krystalreverb Dark clouds indeed. I miss the carefree, responsibility-less days of my youth. The vivid colors of life slowly fade to a drab grey for most of us, but I hope this kid follows his interests and finds happiness and purpose.
Can’t believe they really locked 3 birds in a spaceship for all eternity and let them loose their minds just to find out what the last thing to ever happen is.
Maybe they had the time machine from Futurama, just cracking open a couple brewskis and watching empires collapse

the idea of something being so far in the future away from us that you cannot even understand it is absolutely daunting and I love it

This really puts into perspective the notion of "old age" that we are used to. Someone living until 100 years or historical event having taken place 1000 years ago always seems a lot. And that shows how brief our existence is. Our lives are ridiculously short on the scale of the universe. It's as if we never even happened.

Version 43 when?@agrajmilind7108
Universe had a beginning it will have an End as well. And if We analyse History then its easy to realise that there isn't a SINGLE civilization in human History which hasn't been destroyed / punished / annihilated for their disobedience and sins. Be it - Babylonian, Mesopotamian, Indus Valley civilization, Persian, Roman, Assyrian, etc. etc.
However, there are probably people who think that this Technologically Advanced Modern Civilization could be an exception. We all can just wait to see or Prepare!
This is the Order of Events according to my limited knowledge & understanding (I can elaborate much more but I tried to be as concise as possible) :-
Collapse of Petro-dollar, Paper monetary system [(actual cause of WW3), many geo-political conflicts and situations are side reasons /smoke and mirrors] ~ 80% - 90% expected to die ~ Many years of great oppression & injustice, more than even now (probably 7) ~ lsraeI ruling state of the World (obvious) ~ Emergence of Mahdi (r.a.) - A Guided & Just ruler ~ Peace & Prosperity for a while ~ Coming of Dajjal/Antíchrist (their much awaited one-eyed Messiah) in Human form (live for 37 days & will do many miracles & many things) ~ coming of Eesa/Jesus (p.b.u.h.) & killing Dajjal ~ Peace for many years (some say 8-9 years & some 40) ~ Coming of Yajuj and Majuj (a corrupt ancient tribe) in large numbers & much violence & killing ~ Their destruction from an infection / disease on their neck by Allah s.w.t. ~ Peaceful death of all the believers from a breeze from Yemen ~ Destruction of the Kaaba 🕋 (in Mecca, Saudi Arabia) brick to brick by Dhul suwaq qatain (a person with short legs) ~ Dwelling of only Disbelievers and Criminals on Earth ~ The Earth will be cursed coz there will be no one to say La ilaha il Allah (There's no God except Allah) ~ Trembling of Mountains & shaking of the Earth (physical destruction of the World and the Universe).
We have been already warned about it!
And there is no city but that We will destroy it before the Day of Resurrection or punish it with a severe punishment. That has ever been in the Register inscribed.
[Chapter 17 Isra (The Night Journey) : 58]
'That they said (in boast), "We killed Christ Jesus the son of Mary, the Messenger of Allah";- but they killed him not, nor crucified him, but so it was made to appear to them, and those who differ therein are full of doubts, with no (certain) knowledge, but only conjecture to follow, for of a surety they killed him not.'

Their stated position is positive nihilism which is essentially that it's great that everything exists, that anything exists, that we exist, and we should find our own meaning and enjoyment to make it worthwhile. If you feel dread at the realization of the transitory nature of all things before time and entropy then you're admitting reality is too much for your feeble mind and that you're too weak willed to face it - the universe has offered us a seemingly impossible challenge and while this is very likely the inevitable fate of the universe there is still much we do not know.

Is it weird that I was low-key terrified of vacuum decay, right up until I watched this? Now, all of a sudden, the prospect of vacuum decay randomly and spontaneously setting the universe ablaze no longer feels like a horrifying annihilator - but a universe-wide reset-button, potentially allowing something new to flourish once again.
and the best thing is, if we're correct in our understanding of vacuum decay, and if the uncertainty principle isnt proven wrong, vacuum decay is GUARANTEED to happen over the long and slow death of our current universe. Infinity is a long time for anything to happen, after all.
@@offensivequandal6334at that point, though, considering how unlikely it already is, and using this to roughly calculate when it would be inevitable to occur, everything in the universe would be so far apart that it might not ever collide with anything, and this is already assuming that there is anything of note left in the universe when it finally happens.
Which is terrifying once you compare Vacuum Decay to how our universe supposedly came from…
@@apollyonnoctis1291 You see as the universe endlessly expands past the point of no return the speed of light. Don't you see the endless cycle. This new supernova of a black dwarf could create a new universal constant. We might all be localized environments due to a single black dwarf from a universe that died long before us. The expansion of space that happens faster than even light itself may be a reflection on that as our previous big bang the OG supernova of a black dwarf may had at a time been a star in a much larger system that is now impossible to observe
@offensivequandal6334 we will all be the same, we will all be one, after all.
@@apollyonnoctis1291 the extent at which the vacuum decay will encompass does not need to wash over remaining matter. all it needs is to well, happen. then we enter the realm of the unknown as we dont know what a truly stable higgs field looks like. and even then the vacuum decay WILL wash over remaining matter. this is because of entropy and the law of conservation of energy. mass and energy cannot be destroyed nor created, only altered, and in the process of heat death, energy and mass will remain, however in unusuable forms, kind of like vhs loss where if the tape is copied over and over, it eventually turns into static. however the original content is still there, the building blocks are still there, and vacuum decay will wash over these building blocks, it is just a matter of when

@@ProfShibeThat's awesome to think about. Thanks Prof!
How strange would it be-that out of all the civilizations possibly out there-we are probably the most advanced in studying this topic?
It's actually quite fascinating to think about: We exist close enough to the literal start of _everything,_ that we can partially still observe the direct aftermath and all stages between _then_ and _now._
Our understanding of physics and the universe is so big, we have a guess at what will happen in a future so distant, that we can't even abstractly understand just how utterly insanely far away it actually is beyond "it's a _really_ long time until then".
The entire human existence is like a grain of sand in a desert compared to the current age of the universe. The universe's current age is a grain of sand in the desert to the time, it'll take for all matter to turn into black holes, neutron stars or white dwarfs. The time until that happens is like a grain of sand in the desert to the time it'll take for black holes to evaporate and white dwarfs to become black dwarfs... and all that time is still just a grain of sand in a vast desert to what might happen thereafter (if our understanding of all this is correct).
There is a time in a (not nearly as distant but still) far out future, long after Andromeda and the Milky Way have merged, when sentient life will look at the skies and see nothing that's not directly in their own neighborhood.
All lights in the sky will be contained within their own galaxy. The background radiation, that allows us to analyse the big bang, will have become indistinguishable from background noise. All other galaxies will have moved beyond the range in which their light is able to outrun the universe's expansion.
Those lifeforms will not be able to understand how the universe was formed, they won't know that there's other galaxies out there (and even if they did, it'd be functionally meaningless to them) and they would see barely any new stars forming, maybe not even see old ones dying, given that most stars will be long-lived ones, that'll still take an absurd amount of time to run out their fuel.
It's mind blowing to think that we live in a time, where we can look at *_both the possible start and end of the universe_* and that there's a time in between when sentient life will have absolutely _no means_ to do the same. To them, the universe will be entirely static and appear to be eternal and unchanging both in the past and future.
You're a saint 🙏
Another thing to note is that humans are super young relative to even the creation of the Earth, which itself is extremely young. Humans compared to the universe have been around for practically zero time, yet we’ve already managed to advance to the point where we could end our own existence within 12 hours at any given time.
Humans really are the masters of destruction. I truly wonder if there is any other civilization in the universe that can rival our destructive capabilities. And the fact that we use it all on ourselves if the funny part. We were just born to fight, kill, and hate each other.
@@SJ-di5zu Sometimes, humanity seems bleak, keep in mind we also created arts, philosophy and science that allows, for instance, us two strangers to communicate across the globe in real time.
@@SJ-di5zu I think that the ability to utterly annihilate itself is necessary for a civilization. Meaning that no matter what Aliens exist, if there technology advances at one point they will be able to annihilate themselves. Almost all predatory animals and a lot of non predatory animals kill each other in fights for territory or food or mates. We really aren't special in that way, only that other animals use primitive weaponry like teeth or claws (like our far ancestors used to) but we now, as a necessary side effect of an industrialized globe spanning civilization, have the ability to cause far greater destruction.

This is a great video, and I love how you put 3 misspelled versions of your team’s name before you got it right. How the word is misspelled shows that the person typing it got a bit frustrated trying to correctly spell it. The amount of detail put into every second of these videos is incredible, considering only a few people might notice any particular thing. All of these little details make these videos so much more full (or in this case, deVOID) of life! Keep up making such great content, it’s truly inspiring!
An idea expressed in an earlier Kurzgesagt video was that the universe could theoretically have died and been born again multiple times. Could the gravity of the matter emitted by the hawking radiation eventually pull all the matter in the universe into one big ball that causes the next big bang?
Stumbled across this comment right after learning about the Buddhist understanding of what causes rebirth and reincarnation (the ideas of Bhava and Vibhava) so this is blowing my mind.
Apparently there's been consideration of an alternative to the big bang, it's known as the big bounce model. It's still under review since it got brought up recently in '17.
@@IFoundGodInEminemIf this happened, it wouldn't be a reincarnation
@@AztecedaHow is that an alternative? Big bounce leads to a new big bang.
Lets say big bang comes in cycles is true. Why does it do that? Shouldnt it reach equalibrium and stay as a singularity? Does conscience have a part in it? Is it trapped and tries to escape the physical singularity but fails everytime to develope into something higher (through species on different planets) until next dead universe?

I love how he just discussed the most horrific thing that’s going to happen to space in such a calm voice
Ain't gonna lie, every time I think about the very end, it terrifies me and gives me a huge anxiety attack. My mind is petrified of the thought of it despite knowing we won't be around to witness it. I find it a challenge to overcome the anxiety it gives me and I don't think I can ever overcome the thought of it.
No need to worry. We are control of nothing. Enjoy living this life is all we can try to do. Nature is ultimately in control and supreme above all else so in my opinion it is unnecessary to worry about anything that far into the future. There’s enough to worry about in life without this. Just relax and let things happen
@@mattorr2256this exactly
We call this empathy, You woring about the future of others, it all matter, you're a good soul, who knows this is how our universe is born and it maybe what the nextone will be aswell.
As soon as we grow older there is nothing more to be worried about because the only thing more peaceful in our life is an eternal rest.
Bruh why tf are you worried about stuff that your great great 10000x grandchildren don't have to worry about?
Worry about yourself and your own life. There is far more you can do to improve yourself, rather than worrying about being an atom on a spec of dust in the cosmic desert of our universe
how you guys keep spoiling us with these high quality, beautiful animations so frequently is beyond me. big kudos to the team
This video is truly a mind-blowing journey through the later stages of the universe's life. The concept of the universe's eventual death, as unsettling as it is, is presented in a very engaging and comprehensive way. The illustrations are just as captivating as the narrative, making complex scientific concepts accessible and enjoyable to learn about. Can't wait to see Kurzgesagt comes up with next!
There are theories that maybe it still wont be an end! Some time later even the protons, and neutrons will decay, so there will be no atoms anymore, but there will be a lot of neutrinos! Those are only very weakly interacting with each other, but it is possible(at least it can be calculated) for them to be bound to each other. The problem is, that the bond is weak, basicly the universe is too "hot", there are too much momemtum of the particles for it, and the calculated size of that neutrino "atom" would be bigger than the current universe. BUT, the universe is infinitely expanding, and in the process cooling, so there could be a time when the universe will be big and cool enough for a neutrino atom. From then on, with those there could be other structures, maybe like planets or stars based on neutrinos, so the universe will live again!
Hope is all we could ask for 😊
Yeah.. "Comes up with" indeed.
These visualizations are just mind blowingly nice. You're doing such a great job 🙂
This is one of my favourite videos from this channel - and that's saying a lot! So well explained and animated. I don't know what I'd do without these videos popping up and making the existential crises seem irrelevant. Thanks Kurzgesagt!
Outer Wilds already helped me process all of this, and I've accepted it. Even if my life ends long before anything else in the universe happens, I'm glad I existed in it.
*sits by a campfire and plays a flute like object*
Greatest game of all time. Changed my life.
At the end of the universe, let's gather around a campfire and play banjo together.
omg such a good game
Outer wilds, my beloved...
There are so many hidden details in this one, like how the density of a black hole displays strange symbols at first, before resolving into "ERROR - Calculation Failure" (2:38)
such an amazing channel, keep up the good work 🤩
Definitely!
7:17 _"The difference between a second and trillions of years has lost all meaning"_
There's a quote for the ages! (eons?) Imagine learning galactic timescale is so mind boggling long, only to be told that THIS makes that look like child's play!
I remember a scientist discussing a possible connection between heat death and the big bang theory.
I'm horribly mangling it, but I remember it went something like: When entropy reaches its highest possible state universally, all black holes have evaporated and all matter has degenerated into energy, there can no longer be any measurement of time or distance. At that point, the fully expanded and cooled universe could just as easily be considered a singularity from a different perspective which could in turn result in a new big bang. Since any intervening time or scale is irrelevant at that point, the only thing that matters is for the potential to be above 0, and since it supposedly happened once already, the potential is already above 0.
The main issue I find with this idea is Planck's constant (assuming it remains constant at this scale) and the various flow-on effects that may have. But then, we have no reason to assume any possible future or past big bang's would have to follow the same development path ours did anyway.
Anyway, my point is: The last thing that will ever happen might also be the first thing that will ever happen, from a different point of view.
That’s very interesting. Does this suggest that, without the constraint of time, anything with a probability greater than 0 would eventually happen?
I’ve wondered this before, but it was explained to me that despite unlimited time, something with a probability that infinitely approaches zero (but does not equal 0) may still never happen. It bummed me out because I thought I was on to something.
@@MrMan-sy4evThis channel has already covered it. The video is titled, 'We did the math, you're dead'.
@@MrMan-sy4ev Good question. I have no idea. On the bright side I found the hypothesis: Conformal Cyclic Cosmology by Sir Roger Penrose. I remember seeing an interview with him on the subject, but can't seem to find it now. Looks like PBS Space Time did a video on it: "What Happens After the Universe Ends?" Hopefully it would have some extra detail and will check it out myself after work.
@@MrMan-sy4ev If I were to roll an honest 6 sided dice 10 times, and rolled a 1 each time, what is the probability that the 11th roll will be a 1? It is 1 in 6. It is not more or less likely than any other time. So the quantum tunneling is very... very unlikely. But not so unlikely that it would not happen. The entire earth spontainiously jumping a lightyear is much... much less likely. It will never happen.
That's beautifully poetic, the end 'end up' being the beginning
I haven't been this close to having an existential crisis in a long time, but I can always count on Kurzgesagt to deliver!
Bro, you’re stressed about the universe ending in 10 to the power of Gogol years lol
@@d.n.3652 Well for one thing, what may not be a big deal to you, may be pretty impactful to others, so don't judge. Secondly, it's more about feeling utterly tiny and insignificant when compared to the vastness of all that time. I mean, my lifespan is already insignificant when compared to the current age of the universe, and if the age of the universe is insignificant when compared to how long it's gonna be around, where does that leave me?

If you want to, watch Timeline of the Future, its basically this video but on steroids further delved in, that one gave me a big existential crisis about this topic, so I was kinda immune
@@Gamorou I had my existential crisis long ago when I was a kid. As an adult, this stuff doesn’t have that effect on me anymore
This is probably my favorite Video of all Kurzgesagt, the music, the timing (8:34), the topic the vastness. I nearly cried out of awe. Thanks
Neil DeGrasse Tyson's "StarTalk" discussed the possibility of going through black holes to white hole big bangs in another energy rich universe, and adapting to it's physics. Existential crisis solved.
@@Highlyskepticalyeah, the guy that believes conspiracy theories . That one.
@@Elitaria If you don't like Neil, do you like Discover magazine? The article titled "Conquering Maxwell's Demon" discusses how a massive supercomputer could reverse entropy...hypothetically.
@@Highlyskeptical those were in legal trouble for false inform twice
@@Elitaria If you're right and they're wrong, we still have over 100 trillion years to come up with something better...I'm optimistic.
9:00 I can feel the pain of not being able to vorrectly spell "Kurzgesagt".
Correctly
@@NguyenMinh792That was a joke.
Yep got that
RT Omega !!!!
The ending really gave me chills... No matter how far away it is, expertly woven story arc and brilliantly performed (narrator and animation in point as ever!).
I love you guys, never stop doing your thing!
If we perceived 100 million years per yoctosecond (Yoctosecond 1,000,000,000,000,000,000,000,000 = 1 second. It'd be no different than our current situation. In this imaginary perception of time, it will still takes soooo long before that happen
Why did it give you chills? The last thing that ever happens in this universe, this supernova discussed in the video by a collapsing black dwarf. Is merely the next big bang that restarts the next universe. See nothing to fear here at all. It's simply the same thing that has already happened countless times and will continue to happen countless more. Everything is as it has always been and always will be. There, feel better now?
Our sun will die long before this, much bigger issue and even that isn't really.
Guys, if something is giving me chills, it doesn't necessitate that i am afraid of experiencing it for real 😅 why would I think that?
As stated: the narration and presentation conveyed an eerie feeling that really took me along for the fictional ride. And I applaud the minds that created this video.
@@jasonwrner There's no evidence to suggest it repeats itself into another big bang.
the universe will never end bc for something to end is for something to have been which is impossible once the universe ends bc nothing will ever have been bc there’s is no time or space or anything that ever is therefore was
Most people here describe how calming it is for them to understand the true insignificance of existence. But, somehow, I just feel so sad knowing eventually everything will cease, forever. Even the tiniest change or effect will amount to the same as if it never happened. And pessimistic as I may be at times, I care too much for the world to see it end.
By the way many great minds (scientists not philosophers) consider that we don't know so much more than we do know, that the story here is most likely is not true. One famous example is Penrose who won a Nobel Prize recently. One of his theories suggests that the end of the universe depicted here is mathematically equivalent to the first moment in the universe, that is big bang.
Read about it and other theories, and be optimistic, life is so much more than we know, and it is quite ignorant of us to imagine that we know enough
I started watching your videos cause I found your book about the immune system in my local library and was in awe and in love. Please publish more books!
the final supernova was made so beautifully (with soundtrack and narration and everything ), I felt a sentient flow that made me feel like crying 😢 it's like an epilogue of an orchestra, or a farewell to all the wonderful thing's that has ever happened.
4:34 the sun 💀
Little bonus for the curious: the same quantum effect is expected to turn every object in the univers (lonely planets, asteroids, Voyager 1, dust, etc.) to pure iron on scale of time absolutely enormous. But those object, because they aren't degenerate, won't explode. Instead, on a timescale bigger still, every atom will quantum tunneling to theirs center and ultimately create a small black hole that will eat the rest before evaporating in the blink of an eye.
“When the first living thing existed, I was there waiting. When the last living thing dies, my job will be finished. I'll put the chairs on the tables, turn out the lights and lock the universe behind me when I leave.”

last living thing huh? I hope the dude got some books. Cause he be waiting for a looooooooooooooooooong time XD
I wonder if she has to wait for that final bang (and that forever in between) or can she just see to the last ”living” thing and then either move on or kind of speed run the rest of the universe’s end? 🤔
@@RiosWong In the graphic novels, Death, as well as her siblings, is a child of Father Time and Mother Night. She is an eternal being, known as an "Endless", who will outlive even Gods, as well as her other siblings. She has time. As you may or may not know, Death catches up with everyone and everything eventually.
Uh, I remember reading that exact same phrase in Discworld. One author probably referenced the other because if I'm not mistaken they were good friends
@@kirakuroe when the last living thing dies the universe will cease to exist.
this was a breathtaking episode, kudos to the team. i love this kind of stuff
Its so weird hearing Kurzgesagt talking without backgrounds music. its almost suprising
This channel forumulates all the scattered, galaxy brain thoughts that are hard to even articulate into words in my mind, into more concise structured questions, then dives into it each one. Thanks again for all the amazing thought provoking videos!!!
It is all wrong tough.
@@MegaBanneHow?
@@MegaBannewhy is it tough though?
@@wicketd2 The idea that entropy can increase in a closed system is based on an a system that can be open and closed on demand.
Because if yo want to reduce the entropy of a system you have to interfere with that system from the outside.
These systems are technically speaking not closed.
A real closed system can't ever be opened from the outside.
The only closed system that exists is our universe.
The universe definitionally speaking contains everything.
There is no thing to open it to.
The entirety of the universe has no walls.
It has no end.
It is infinite in every way imaginable.
This is why there is no end point, where you can theoretically add or subtract energy.
There is no physical mechanism that would reduce entropy to the state before big bang supposedly happened.
Meaning big bang is a misunderstanding of the evidence.
The laws of thermodynamics demands that we need to live in what astronomers call heat death (more academic term is thermal equilibrium).
There is a balance between all the forces of nature and the energy of the universe.
It is like how a gas in an approximate closed system reaches an equilibrium, where all energy is evenly distributed, there will still be molecular structures that are forced in to exist.
Molecular structures hinders the increase of entropy.
This leads to most of space being empty.
This is similar to how our laws of nature is obviously keeping most of the universe relatively empty.
The fact that none has agreed on what causes our universe to take roughly the shape as it does now for ever doesn't make it less true.
Ignoring the laws of thermodynamics comes with huge issues.
The second law of thermodynamics is a statistical concept of cause and effect.
You need to abandon the idea that things happen for a reason if you want to abandon the idea that our system can just randomly reduce in entropy on the astronomical scale needed for big bang.

Can you please read the comment I made to wicketd2.
No point in copy pasting it.

Why stress about what’s happening now when you could stress about what’s happening in ERROR years?
Great video as always!
This is a great way to say that number xD
2:23 Poor brown dwarfs
I feel bad
They aren’t losers!
Just imagine in 500T years everyone will be dead and the universe will be gone, nothing will ever happen again.
At this point, words can no longer describe how good your work is, guys. Thank you for your amazing content!!
dude fr
This had a sort of melancholic and soul-touching beauty to it... a video and dialogue that has touched me in a way I haven't experienced since I first heard "Pale Blue Dot"
Thank you, writers and narrator, for sharing this breathtaking piece of knowledge
@@JackWilkego outside. Go to the gym, read a book, shave your beard, do SOMETHING helpful to society you social reject.
i feel like when one universe dies, its quiet for a while, and then another big bang happens creating a new universe. i also think theres multiple universes alongside each other like galaxies living aside each other. it's mind blowing how infinite space really is.
I think people forget to realise the idea of the universe is a philosophy, its just everything as a whole, there is nothing outside of it our influencing it will always be unified, I think believing in its death is not believing in everything being universal defeating the idea of a unvierse
Time will continue to accelerate.
yeah gravity just pulls all the shit back together again in a tiny ass ball and then some physics happens and it explodes again
what? I think you misunderstood, I'm saying everything is whole, by saying these things such as a time and energy and so on defeats the purpose of the universe because there seperate entities and aren't universal time itself isn't a definite but a philosophy and the sooner we understand that the sooner well get to having an uncontradictory system in which the universe comes from nothing and then just turns into nothing defeating the idea of a universe
@@felixstone3.14
My main problem with this theory is this- how do you define a single universe in a collection that are physically separated by space like that. The definition of the universe is that it’s everything in this space-time dimension, so by your logic those aren’t “universes”. But are instead relative and subjective sub-pockets limited by their own cosmic horizon
wow, i dont have a lick of an existential crisis when i watch these space videos. i feel comfort. like i know the universe is harsh and doesnt give a shit about us but still.
I had a nightmare one time when I was very young that felt very similar to being a black dwarf. I was aware that I existed but I had no ego. All I could experience in this dream was immense pressure from all around, and I felt like I was a super dense rock. Time was irrelevant and I felt stuck here for a long time. Quite an out of body experience for an 11 year old.
I had a dream around the same age where for some reason I had to hold up this giant stone pillar that reaches for miles into the sky, like Atlas or something... maybe there's some pattern behind these kinds of dreams...
Sounds like they could be a variant of sleep paralysis? Instead of the usual type of someone sitting on your chest, your brains went all cosmic with that feeling?
@@andyjones5872 idk it only happened that one time. I’ve had a lot of issues sleeping since then. My brain always wants to ponder death and the void when I’m trying to fall asleep 😅
You cant just say that; theyre called 'little people of color'.
