The universe today is happy and healthy, with exciting things going on - but at some point the night will turn dark. Everything that once was, will peacefully sleep forever.
But what is the last thing that will ever happen? Let's travel to the end of the universe…

Cuz theyre brown, huh?
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..
i guess i kinda maybe got it in my reply? minimal or negligible difference between time units
For a point of reference, 10^1,000 is insane when you consider that the amount of atoms in the entire universe is estimated to be about 10^80.

All my friends have kids with normal fears. Monsters, strangers, etc. My kid is afraid of strange matter.
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.

The storytelling ability of this channel is absolutely breathtaking
Du bist atemberaubend
You are right
The voice is very fitting aswell
@@repentandbelieveinJesusChrist1why are you preaching💀
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).
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.
On the flipside, ignorance is bliss and lower intelligence beings don't have to grapple with the fact they will ultimately die.
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
@@mattorr2256amazing, isn't it. I find it both calming and frightening. Too bad I think I won't be able to know all the answer after all
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.

@@Zargabaathcalm down Dark Eldar
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
Sacrifice for science
Suppose they should tighten their minds then?
Lots of people want to see the last thing in the Universe. There's even a restaurant there,
*birbs
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.
You have suffered infinitely more in a minute of living than you have suffered in the amount of time before you were born. You will always exist in one form or another either as matter or energy. You are the universe experiencing itself for a short time on this planet. That’s beautiful
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
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..
I believe in the creator aka GOD
The universe is a wave, banging Bigly time and time again. Maybe
Hope there's pizza in the next universe. They will miss out otherwise.
so basically, maybe it'll restart
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.
because we are those particles,
and like black dwarfs;
we will kill ourselves too, and go with a bang

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.) ✨️
Incredibly based.
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. ❤
Begitu ya bang
Thats positive nihilism
Very greaf video as always, thank you Kurzgesagt!!😊
Absolutely fantastic visuals and explanations, as always!
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.

such an amazing channel, keep up the good work 🤩
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'
@@naturaliscontentus5914 it’s not name calling it’s just an insulting and demeaning fact.

Got my order confirmation last week. One of maybe 4 channels I've ever ordered anything from. Can't wait.
It's fascinating and a good guess, but we really have no idea how dark matter would come into play during a time scale this large.
The fact that it will happen so far away in time that we can't even comprehend makes it more existential horror
What, you'd prefer the universe to end soon?
@@enderallygolem it shouldn't end at all. The universe is a dystopian nightmare.
@@YunoGasai414If the universe is a dystopian nightmare, shouldn't you wish that the nightmare ends?
Never got why people are scared of stuff like this. Literally who cares you won't even be there to know what's going on.
Who knows maybe they'll already have solved something like the many world's theory or the alternate universe theory or the white hole theory
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
That sent shivers down my spine. The people of Kurzgesagt never cease to amaze me.
i literally remember watching you ever since i was 6, im 12 now, thank you all Kurzgesagt members for making up half of my childhood
That’s wholesome dude. Always keep that inner child that wishes to question, seek answers, and learn, alive and strong. As you grow well into your adult life and along after.
Later dude!
dont forget that youre still in your childhood! it's easy to let it pass you by
Dopeee, started watching when I was like 15 or so, 23 now, time flies
You're still experiencing your childhood, my dude. You're still a literal child. Enjoy it while you can.
Don't let formal education stop your curiosity. Stay curious!
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 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.
It's nice to know that the last star will fight until it's inevitable collapse. It's inspiring.
Future Gohan reference?!
Do not go gently...
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
Highly recommend Isaac Arthur's _Civilizations At The End Of TIme_ series for something just like this :)
@dom8429 bet you are fun at parties

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.

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.'
Quran: Chapter 4 An-Nisa (Women), Verse 157.
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.@@kooskoos12345

Great video -Kirtzgasat- KURZGESAGT.😉
So beautiful guys. The best way to explain it…
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
I mean, there's many things like that; I'd say like a hundred thousand years is already beyond human comprehension
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.
Its not nothing, its everything perfectly mixed and everything is the same; the universe is in unity
until the another bigbang explodes and the cicle repeats
@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.
@@cozyrecords256that's the most optimistic theory
I love tat they do small references especially hitchhikers guide to the galaxy in space vidios in this on its milliways the restaurant at the end of the universe. It nice to see more fans
1:58 Dayum ... the animation is just fanTAStic.
I woke up, watched this and had an existential crisis all within the first 30 minutes of being awake, thanks kurzgesagt
Literally nothing matters, the universe is indifferent to our existence. Yet it does matter we love life… Hard feelings to battle
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
Well... it doesn't help they're stating it as fact when it's theory. Honestly, I find this is a creepy and insensitive video.

According to our best theories (which may well be wrong at this scale of time), this isn't even the "last thing" that may happen. Classically, if all you have is particles that have spread out and reached an equilibrium state, the universe should be dead forever. But quantum mechanics suggests that given enough time (long enough to make the time frames mentioned here seem like less than an eyeblink by comparison), through quantum tunneling, random things will happen even in a configuration that seemingly should be forever inactive. In fact, there's a line of thought that our Big Bang (and future ones) come about in exactly this way--there's a vanishingly small chance (so small that it's almost indistinguishable from zero, but crucially is not zero) that all the "stuff" will spontaneously go from that maximum entropy state (everything uniformly spread out in which events happening shouldn't be possible) to a near-zero entropy state, which is what the state that led to the Big Bang and cosmic inflation was.
I love this theory, not only does it give us an idea of birth, but death, and then rebirth. No telling HOW many iterations the current universe is in, this could have happened an infinite number of times and we have no idea, but that the math checks out is just enough for it to be a theory.
I don't understand. How could everything all at once just...collapse into a singularity? Won't the expansion of the universe exceed light speed?
There is a problem with that theory though, which is that it is much more likely to form a boltzmann brain (your brain free flowing in space with the memories that you have) than an entire universe. So much more likely, in fact, that it is pretty much certain to assume that you are a boltzmann brain than that this universe exists.
@@thesaltybeard1793 The theory mentioned actually does not need the "old" matter of the universe and would work in a vacuum. Even in a total vacuum, matter and antimatter spontaneously comes into existence via quantum fluctuations. Given enough time this could momentarily create objects, and even more time (on a ridiculous scale) it could create huge objects like our universe
It makes the most sense. If the universe was maximum entropy for effectively an infinite amount of time but condensed enough for us to exist for only a finite amount of time, then the current state of the universe is infinitely small compared to the infinite heat death period. It feels unlikely that we exist in time to see the universe during its infinitely short period of time. But a cycle of death and rebirth makes more sense.
"Over 90% of stars that will ever be born have been born already"
This statement gets scarier and scarier every time you read it.
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.

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
I say Jesus did it
@@trolledfrog6789science disagrees
Then I can die happy, knowing that this'll happen again and again.
@@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.
Beautiful and devastating at the same time.
the animation on these videos is beautiful
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 awesome. We're the universe studying itself and it's confused by its own existence lol.

Well true it could make you feel small , but on the exact contrary it makes you appreciate the miraculous beauty of us humans popping in and staying alive for just a couple of millenia only to be forever erased from this eternal vastness, we are the only way for the universe to experience itself
In that sense, us living things might be one of the only *significant things* to happen in such a seemingly vast, boring and "probably" dead universe

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.
Really well thought out dude! I've had similar premonitions before :ppp its so scary and so fascinating
I think this is the only Kurzgesagt video that hasn’t given me an existential crisis.
I've watched many videos on how the universe will end, either proton decay is a thing, or the universe goes through cycles of death and then is reborn like the big bang, I just find it fascinating.

*The Last Event in the Universe - Summary:*
1. *Introduction (**0:00** - **0:23**):*
The video begins by noting the current happy and healthy state of the universe but poses a question about what the last event in the universe will be.
2. *Early Universe to Today (**0:31** - **1:47**):*
A brief overview of the universe's early stages, from a warm, dark baby to the formation of stars and galaxies. The video emphasizes that over 90% of stars that will ever exist have already been born.
3. *The End of Everything - but not quite (**1:53** - **3:29**):*
The video discusses the future, where stars like our sun will die, and the cosmic gas will run out. It introduces the idea that in a few trillion years, white dwarfs will dominate the universe.
4. *Black Dwarfs and the End of Stars (**3:34** - **4:16**):*
Explains that, after trillions of years, all galaxies will evaporate, and every object will be on its own. Black holes will slowly fizzle away, marking the end of supermassive black holes.
5. *The Weird Physics of Black Dwarfs (**4:29** - **6:05**):*
Details the strange physics inside black dwarfs, where matter is compressed and electrons keep the star from collapsing. Describes the process of quantum tunneling, making black dwarfs the last interesting things in the universe.
6. *Fusion in Black Dwarfs (**6:22** - **8:15**):*
Explains the unique fusion reactions occurring in black dwarfs, involving slow processes over trillions of years. The video highlights the eventual decay of Nickel-56, leading to the destruction of electrons, impacting the stability of the black dwarf.
7. *The Last Event - Supernova (**8:21** - **8:56**):*
Describes the catastrophic event when a black dwarf loses too many electrons, leading to an uncontrolled collapse - a supernova. This is presented as the last spectacular event in the universe, filling it with light before quickly fading into darkness.
8. *Conclusion (**9:03** - **9:16**):*
The video concludes by reassuring viewers that the last event is so far in the future that it hardly affects us today, emphasizing the current favorable conditions of the universe.
Amazing 😮
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.

Could a black dwarf supernova be so powerful that IT is the Big Bang? And the universe has just been resetting over and over again?
Thanks a lot, @Kurzgesagt. This was indeed unexpected. Amazing animation as well.
Concerning the topic, from the video I did not get clearly what is left after the explosion. Perhaps it is a cold metal sphere.
Also I thought about the fate of the other objects, which was not mentioned here. Neutron stars. Turns out that for some neutron stars their rapid rotation is the last thing that prevents them from collapsing to the black hole. The rotation decelerates slowly so at some point they may collapse into the black hole (and eventually evaporate). I assume this is also a terribly slow process that may potentially compete with the fusion in black dwarfs.
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!
