The death of the universe
HTML-код
- Опубликовано: 11 дек 2013
- The shape, contents and future of the universe are all intricately related. We know that it's mostly flat; we know that it's made up of baryonic matter (like stars and planets), but mostly dark matter and dark energy; and we know that it's expanding constantly, so that all stars will eventually burn out into a cold nothingness. But is there any beauty in this dark ending?

The Universe is too inconceivably brilliant and mysterious. I love it.
indeed
+TheLast2nd Your part of the Universe so you love yourself.....Idk I though that would sound better lol
It sucks though that we will only know a very very very small part of it since it is so big and vast.

It’s almost scary
That is incredibly depressing.
Yeah, right

@@jasonh.7753 who knows we could be very wrong about the end
@@jaydienparks5658 Sure. And when I take dumps and dont look when I flush it could be rainbow colored. But baesd on current knowledge I know it is highly unlikely
It never hurts to be reminded of how we are indeed living in an extraordinary time in the life of the universe!
We always are true beauty is pure and ultimately simple literary
"Don't focus on the finger, or you will miss all that heavenly glory."
Sad that most people don't know/will never know this
My heart just dropped....the thought of EVERYTHING ending is just so.....scary.
I have the same thought!
Let it go
We don't know if it's "everything" though, there are theories about multiple universes. However, for humanity as we know it, it'll be the end.
@@kevinmendoza5035 how?
@@allawy Well if our universe will die, how about move to another universe who still out there?
This makes me grateful that I was born on this amazing planet, and it breaks my heart that Earth will cease to exist one day, along with all the stars and planets, and only left with a dark, cold universe that was once home to Earth, which was home to us.. 😔
Its not the only theory ...
😔😔
@@malinisinha5197 Tell me more ...
But only if you are aware of the difference between a well-informed scientific theory (that's what interests me) and mystic/esoteric/religious folklore which lay people call a theory (not of much interest).
It will cease to exist. Imagine the earth is an apple that is long time (which is relative) on a tree. In the beginning it is nice and juicy , little by little it starts to deteriorate while it feeds small creatures and these creatures are us . Eventually rots and falls to the ground. End of the earth . But there are so many apples on this tree
We deserve heat death asap tbh.

The universe began from nothing. So perhaps the nothingness in the future will fuel the beginning of a new universe. Perhaps beyond our observable universe were the heat death of a previous universe.
It's the CIRCLE OF LIIIIFFFEEEE. Sorry, I had to.

Amazing? But what will happen to us? I care only about humanity.
Hence the white hole theory.
+bananian It didn't begin from nothing. It began with a particle the size of a grain of sand, and basically infinitely dense. Suddenly, it blew up and voila; the universe.
If you didn't feel insignificant enough already.
+William Wilson Insignificant? Keep in mind that of all the energy in the universe, we might be the only bits of it that are aware of ourselfs. We humans might be the most significant part of everything.

Significance is a human concept. There is no such thing as "significance"

Well. Its a theory right? We obviously don't know what will Really happen. Or what will be the universes fate.
Well no, what’s happening now won’t happen again when the universe begins again. But if the theory of there being a multiverse is true, and there are a decillion universes or so, then there will have to be an exact copy of you in a different universe copying your every and exact move
There will also be another copy of you doing the exact opposite. If you choose to stay home for college, this alternate version of you went to live on campus and so on

I highly recommend reading "the Last Question" by Isaac Asimov, it's my favorite short story that touches on the topic of the Heat Death of the universe with a little twist at the end
If the universe is flat, with defined borders, what is outside the universe?
anything, or nothing. I'm not sure this video presented a finite universe, however, just it's shape. Very few of the theories I've read on the universe present a finite universe, either. It's likely that the universe is infinitely large, though I don't have many direct sources to link to. Check out Henry's explanation of the Big Bang misnomer for a clearer demonstration of infinite universe expansion.
There is quite an accurate answer to your question.
Before the beginning of the Universe existed nothing, or empty higher-dimensional space. It was a perfect phase of nothingness. From 0 to 10^-43 seconds is known as the Planck Epoch. At the Plank energy (10^19 eV), the gravitational force was as strong as the other quantum forces, resulting in a probable unification of all forces, a single force denoted as the "super force". This resulted in a perfect symmetry. At 10^-43 seconds after begun the creation of the embryonic universe. This occurred due to a breakage in the super-force due to a random quantum fluctuation. Gravity, broke from the super-force, causing a quake through out the whole universe. the other three forces were still unified, they are denoted as a smaller symmetry known as GUT symmetry. This is called the GUT era. (Temp = 10^32 C) After 10^-34 seconds the strong force broke from the GUT, resulting in the end of the inflationary period, and transitioned into a common friedmann expansion. The universe consisted of many particles, at 10^27 degrees the gluons, quarks and leptons condensed into baryonic matter, and such. This is important in giving you an image of the Universe. The universe has defined borders not in terms of the observers within the universe, but the observers outside the universe. This universe is an embryo of unlimited space-time, space can be stretched infinitely, and you can travel in it infinitely without ever reaching the end, because you are the observer.
If it is flat, it only means that if you construct a triangle with three straight line segments where all end points are in contact with another, the angles inside the triangle equate to 180 degrees, the shape of the universe doesn't particularly mean much, when asking what is beyond. What is beyond is theorized to be a perfect phase of nothingness. Nothingness just waiting for a random quantum fluctuation.
The Bulk of higher dimensional region contains the universe.
Mexiconian land
What's on the other side of the universe
My theory is that after the cold and empty death, another big bang Will appear to save the day and create another universe
+supermassimo Animations I think so too. Only that it wont create a new universe, only spread matter in this existing one. If dark energy eats up all the matter and radiation, there will still be space. Maybe this is what happened before the big bang we know today.
Try*
+supermassimo Animations Well its possible through quantum tunneling energy from before the heat death can enter the universe and cause a transitional period, a "phase change" in which the laws of physics are pretty much broken, rewritten, the universe becomes a whole new thing and then it allows spontaneous creation of matter/energy much like our very, very, very early universe did.
Yeah if we dont really know what dark energy is then maybe if there is too much of it the dark energy will make a big bang and dadaa a universe
you think there was another universe before the big bang?
Thank you laws of thermodynamics... for killing our universe :(
Without them you can't live :)
However,there is the Poincaré's theorem of recurence, which authorizes the entropy decrease. It was a breach in the entropie theorie, but when Boltzmann calculated the time it take to reboot the universe, it was so big he neglected this problem.
@@rolletroll2338 you can actually reverse entropy and still live
Jaydien Parks no you cant, energy cannot be destroy thus that makes entropy irreversible and that also what make time travelling impossible
@@rolletroll2338 I don't care if can't lieve whit out them if we're all jsut gonna die then I would just say No thank you you can just not exist.
@@chezus7716 Buddy, Heat Death is quintillions and quintillions of years away, we'd either be long, LONG extinct, or have travelled to another universe or created a simulation to live, if both are indeed possible. When the Universe reaches Heat Death, nothing about you or me or anyone alive right now will exist. If the Universe had max entropy right after the Big Bang, no life, no machines, no stars, pretty much nothing could've formed. And, I'm sorry, but, your grammar is atrocious. Mine isn't that good, but please, use a comma.
The music is so perfect for this video. I still get goosebumps.
This literally inspires me and prompted me to look at the night sky outside the window , breathe deeply and say thank you for this amazing chance to live in this era .
The final quote in the video makes me think. It sounded like we are privileged to be alive in a fraction of the Universe's lifetime where all of its fundamental structure is detectable. But what if it's not and some bigger whatever is already out of our reach because dark energy expanded it beyond our horizon?
Civilizations that live in a galaxy in the very far future might not be able to detect anything beyond their own galaxy. They will believe this galaxy is all there is, and they might feel privileged for being able to "know" that, just as we feel right now.

R.I.P universe you will be missed
how can the universe be flat if it goes on in every direction, and what is at the "end" or the "blrder"?
Think about how something implodes/explodes, most of the blast is concentrated into ring (remember what it looked like when olderon exploded in Star Wars if I didn't explain it enough) so since the universe was formed from an explosion or implosion ( implosion if the white whole theory is true) then it would make sense that the universe expanded into a flat surface.
+Thomas Harneshaug The theory is you just jump to the other side, its not like a wall.
Unless Donald Trump becomes a god and builds one.
+Angrarian Archdemon really lmao
its a hypersurface in hyperspace. Normally surfaces are 2-dimensional, and exist in our 3-dimensional space. However, we live in (at least) 4-dimensional (maybe more) spacetime, so the spatial part of the universe is a 3-dimensional hypersurface in 4-dimensional spacetime. Don't try to imagine it, our brains are not made for it.
I just hope that such a fate never happens to us. We'll find ways to prevent that from happening!
No we aren't that powerful
Sadly... White people won't exist in 100 years, so basically we won't be able to advance in science. So we won't be able to prevent anything.
I severely hope so too
@@e14ee What the heck?
@@e14ee 🦗🦗🦗
I wonder if there is any feasible way that sufficiently advanced, intelligent life could survive the death of the universe...
If time travel is possible yes.
Soklay Thing is... as the matter in the universe becomes infinitely dilute, even tiny organisms will not be able to coalesce.
Time travel is an interesting thought, but then wouldn't the universe be teeming with infinite amounts of life as populations grow and maintain their existence inside the timeline of the universe? Idk honestly I think I'm talking out my own ass now.
There is no such way. The laws of the physics apply to life as well. Universe ends, life ends. Simple.
Life is a local minimum of entropie. If nothing is done, the entropie of a living thing will increase. To maintain your entropie low, you need to increase the entropy of your environment. In other words, you need energie to live, and you use this energy by degrading it into a non-usuable form (heat). If no energie can be extract from the environment because the entropie is too high (a too uniform temperature to use thermic machines to extract it) , you will loose your usuable energy to death
Wormhole to another universe?

Tony black atheist Malone human race could evolve in something to survive in future climate and earth conditions. it could be either dumber or smarter.
@@DEADLY_HUMAN climate change is an aweful lot faster than evolution.
Let's be optimistic and say we last for trillions and trillions of years, especially if we colonize other planets in a few centuries.
We will take to the stars in a few years!
If the universe is like 2200000000 trillion lightyears long then there is BOUND to be another life form somewhere
HeadySettyOfGames Of course, but is that life form going to be able to save us from Heat Death if the theory is true? I don't think so.
No one can stop heat death because it's universal. You would have to individually make every atom of energy invincible ( which is impossible because infinity is only a concept and nothing is forever) no amount of technology can save us from the inevitable. Sorry if it's depressing but the universe will die. Thankfully though the universe is still very young (13.9-14 billion years old) so humanity will have been extinct for extremely long. Heat death cannot be avoided and cannot be stopped.
Raven Karns bruh shutch bitchass uP
We won’t be able to reach that life though because once we have the technology the universe would have spread apart so far it would be impossible
Life will restart infinitely This means we have an infinite chance to have everything back.
I have one question.... Will there be once again a big bang and creation of a new universe??
That's what I'm thinking too lol.
Due to quantum fluctuations, it could happen. But, it will take an extremely long amount of time, even after Heat Death for something like that. Though, life will most likely not be around to experience that, so it will most likely happen in an instant.
A great mind said: "If we do not destroy ourselves we will one day venture to the stars".
I believe in that. The only thing that can stop us is our own greed and lack of empathy.
a possibility is that at Heat Death, our univer might start a new period of rapid expansion, during wich it might descent into a new, much lower energy state, with a much lower planck lenght
imagine a universe that keeps expanding, and every few trillion years, all of it's particles explode into smaller particles, with new rules for how they interact each time
the energy never increases for the entire universe, and the heat keeps decreasing
i dont understand, why would the plank length change?
Heat death... That will be so interesting to see. I can't hardly wait.
The voice and animation: 😁🥰😍😇
The conclusion of the video:🥶💀☠
That animation was glorious.
how the heck did you get your name like that?
As a layman who has been interested in cosmology since I was a teen, all these concepts are something I know and understand to at least a basic degree, and I even know how we came to discover some of these these facts.
But I imagine newcomers are scratching their heads in disbelief at such strange concepts. You gotta be more basic, Ted-Ed, or at least longer, you can't expect to fit a whole Lawrence Krauss lecture into 4 minutes :)
I was so surprised because I just watched a Lawrence Krauss lecture of this very subject right before this video.
only a creator can do it. a grand designer.
Says who? What is that notion based on? There is no need for any creators or designers in nature.
When you see a building it didn't just build it self someone thought of it designed it and perfect it before it became a building so is the universe it didn't just create its self there was a maker some where beyond our eyes(spiritual) who created everything, thank you heavenly father for giving us life we really appreciate this opportunity you gave us, thank you Jesus.
I love the animation!
Btw, great lesson!
Does this video give anyone else super bad anxiety. And thinking about things like y we’re here and how. And how things came to be?
Dark energy is sooooooooo cute
Doesn't seem cute at all
It's looks more like demon to me

So literally EVERYTHING will end...good to know

I love the lecturer voice.
Kinda sad that we wouldnt even be here to see all the different things and cool things that would happen 100 years from now :))
The universe being flat is still a theory as well as the heat death of the Universe is still a theory, there are many other theories with as much merit as this one.
Gravity is still a theory.

I have a problem with this theory. This universe is bound to a principle of cause&effect/yin-yang. Basically, for something to happen something else has to happen first. For something to move something else has to move out of the way, et cetera. Nothing can fully disappear, only be transformed. Black Holes do not escape this law.
Matter swallowed by black holes does not disappear. Eventually the energy created by breaking down matter is released from a black hole through a giant gamma ray.
I don't claim to know much. I don't know what this raw energy would eventually do but one way or another it will find it's way back to whatever form it used to have.
Our universe can not end.
We've always been discovering things that made our view of the universe wider. We thought the earth was flat, we found out it was spherical. We thought we were the center of the universe, we now know it has no edges. We thought the universe was infinite, then we found out infinity is finite. We thought the universe was everything, then found out there might be an infinite amount of universes parallel to this one.
Things always get larger. Things designed to make the universe smaller only makes it bigger as we get to see higher and higher above the wall.
It wont be long until people discover taller walls beyond this one, and then a taller behind that one.
This is as far as we can see from where we stand. That's why scientists all over the world are trying to find out what dark matter and dark energy are and behave. From what we know, the expansion of the universe is constant and the force pulling it apart will eventually overcome gravity and all matter will be torn apart at a subatomic level. But of course that's what we know now. As you pointed out science has a limit and we can not know if our speculations will be realized as they are now.
The video sort of confuses the Heat Death and Big Rip theories. In Heat Death, all matter in the universe will disintegrate into energy and eventually even out, no longer allowing any work to take place. In Big Rip, the expansion of space continues to accelerate until it exceeds the speed of light, overcoming gravity and shredding all matter. Either way, this results in a universe where time is meaningless, as nothing will ever happen again.
...It's really depressing, and makes you want to know whether they would actually happen.
when was the beginning and what was before that, how bout before that, etc. etc. not sure if we can ever explain this.
The thing that really boggles my mind is what the shit are we expanding into?
The littlest Oboe
Yeah that's difficult to explain. According to one version of multi-verse theory there's a fourth dimension that holds an infinite number of 3D universes.
The placement of the 3d universes vary from person to person. A grid field, a stack. There are even people who think there are ''weak spots'' in the borders of universes that leak into others resulting in out of place noises and strange shapes aka ghost encounters.
It's so open to hypothesis i generally try to stay away from the subject.
the universe ends when you die. it is your universe, what you have felt and experienced. anything else barely matters to the individual and for the time being i would like to just quote a redhead i saw in a series you might ahve heard of "you know nothing jon snow"
Good thing that no - one agrees with you.
Sorry for my bad grammar (I don't know english completely).
I learnt a lot about space curvature,and I think it's a pretty curious thing. I spent hours trying to understand what means the fact that if you take a "sphere" of space",it could be flat and not 3D. Well,I """ALMOST""" managed to do that,but I'm still titubant about that. That's why I am writing about that: all of you did a lot of lessons including the space curvature concept and what it implies,but I never saw a simple video like those that explain in the same way what is space curvature,why it could or it has to be like that. I want to visualize it,I hope someone will read me and understand what I mean.
AND FK I LOVE THIS GIRL'S VOICE.
Great narration! :D
Also, very interesting subject.
I think us humans won't have to experience the heat death of the universe. I believe that humans will find a way to travel to another universe or simply create new stars and new galaxies, us humans are engineers and creators.
Looking at the average life span of species (ie 1-2 million years before evolution or extinction) we will be but a distant memory by the time this occurs. All matter has been around for around 14 billion years since the cosmic singularity. The earth was around 3.9 billion years ago, biological life only around 300 million years ago, and hominids around 10 million years ago. The universe still has 10's of billions of years before all matter condenses into black holes, and 10's of billions of years until they all die out. So humanity will not even get to see it. We would have died out looooooooooong before it occurs.
***** Well that's saying that we don't travel to the stars and colonize other worlds. Which as of right now is very unlikely but I have hope that we can accomplish great things.
+Raven Karns a great mind said: "If we do not destroy ourselves we will one day venture to the stars".
I believe in that. The only thing that can stop us is our own greed and lack of empathy.
Wrong, separating humanity will cause them to evolve in different ways, making them non humans
***** Unless you utilize terraforming on every planet (making them as Earthlike as possible), genetic engineering, and social engineering to make people as close to the human race as possible.
Woah mind blown. I love the animation and the music used here.
This video reminded of a quote in the Bible that in the beginning there was "nothing or only darkness or emptiness" I can't say certainly but it males this theory even more interesting like an irony.
A nice video that hides the fact that Physics is incomplete. Dark Matter and Dark Energy sound a lot like ether. I give current cosmologists an A for effort, but an F for understanding.
Seems like you are not familiar with physics or science in general.
This video and astronomy itself has always admitted that physics is incomplete, the very fact that dark matter and dark energy are named as such and recognised is because they are acknowledgements of the unknown and where more research are needed.
Dark matter and energy sound completely different from each other besides their names as well.
I give your effort to understand an F.
KS Ng,
You are making many assumptions of my background.
I'd prefer if cosmologists just said - we can't account for most of the stuff we observe.

I'm afraid the problem right now in astrophysics is to find out about the _nature_ of dark matter, not to keep debating its existence.
Brian Koberlein, an amazing astronomer who writes daily science posts on the internet, has a great 6-part series about all the studies which led to our current _knowledge_ about dark matter. Here are the links:
goo.gl/xpvDZX - Introduction
goo.gl/jGvBjw - The old model doesn't work
goo.gl/lAKQMX - Alternative gravity models don't work
goo.gl/0ee7dc - The dark matter model does work
goo.gl/f7Tzdk - Known dark matter isn't enough
goo.gl/nF1AcZ - We already know quite a bit
Thanks Arturo Gutierrez. This has been the best info regarding this then I have ever seen.
if the universe has a shape,, then what is just beyond that shape? the reason we saw the example of curved or saddled is because we can see the space beyond it.. i don't understand how their can be an End to the universe, or just how can the universe have a shape. i can't wrap my mind around around this theory of universe has a shape.. seems easier to imagine NO END.. no outer edge or nothing like that.. and even that is impossible to imagine
Thats where the ideas of other universes or different realities comes in the idea is that there are an infinite number pf universes next to each other much like a number of football fields side by side
Fire in the head just think of it like an coordinate plane with the _x_ _y_ _z_ origin as the universal center, then the infinate boundry of just blackness and the "edge" of the spreading universe. so like if the universe was a sphere it would stop and the plane of existence continues.
The Ghost of Onyx thats what i thought.. but was thinking that the plane of existence was the universe.. are you saying they are 2 different things? then in that case a shape would make sense.. I'm just mixing the 2 (universe and existence) as 1 thing. man i wish to know this shit before i die. would be interesting
Fire in the head technically, they are two different things, but since we only know of this universe here we think the universe is the biggest thing since we dont really know whats outside it and thus existence when in reality if the universe has an end then plane of existence comes into play, there is really too many unknowns to say for sure
yeah exactly. i agree that its possible that anything outside what we can see could be different than universe. would be sweet to go to the edge if their is one and look both ways. but thats not gonna happen anytime soon. so you would think the universe is inside something? or next to something else? like a box inside a room? even if their was infinite universes next to each other, would they be inside something?
i feel the need to go out on this beautiful day and be happy.
I'd say it's not a heat death that awaits the universe but a cold one. When every star dies is when all life dies. And thus the universe dies.
That’s what heat death is, it’s the death of heat.
@@beastmaster0934 oh. My bad I assume the reverse of that was what a heat death is ^^'
@@SnakeRoadComicsOfficial3677
I don’t blame you for getting confused, “heat death” sounds like death BY heat. But it’s death OF heat.
bro I'm crying I'm scared of it ending
Don't worry, Heat Death is extremely far away, around 1e+100 years away, or 1 followed by 100 zeros. Our universe has only been around for 13.8 billion years, to reach 1e+100 years, it will go through the 13.8 billion years for trillions and trillions of times. Heat Death may trouble you, as it does the same to me, but it's so far away, most likely all remains of a civilization will cease to exist, and you will be very much dead, and so will I. So don't worry. All that matters is the present. Live your life well, and have fun.
TL;DR, don't worry. You'll be dead before that. Enjoy your life.
And what if we don't die because we have found out anti aging, that is going to become a problem for everyone
Also the first problem is we don't want to die or end
@@piyushmenon4987 he said he doesn't wanted to end, you tell him he is going to die before that is just making it more worse, if someone died, it is the end for them, and he clearly doesn't wanted to die
@@Britishball I do think a civilization could still persist around that time, if they have technology that breaks the laws of thermodynamics, somehow, I don't know, so it's just speculation. No one knows. We're all just speculating.
fascinating!!!
Idk, but this video was actually relaxing, just listening to it.
For some reason the heat death of the universe worries me more than the inevitability of my own death.
2:24 r.i.p dark matter
The Dark Energy Charachter though XD
I still don't understand how the universe expanded so quickly in its early phase, slowed down, and then started accelerating again. Do we know the reason for this? And how do we know it won't slow down again?
It started off with the Big Bang. Everything blasted outwards. Dark energy was there too in tiny amounts, even though it didn't affect much, but it was slowly growing. As time went on, the Big Bang's force slowly lessened, like an object slowing down. But, the dark energy was increasing at a slower rate. After a little bit longer, the dark energy had increased so much that it outgrew the Big Bang force. Despite the fact that the force from the Big Bang's blast is still decreasing, it's decreasing less than the dark energy increased.
Well, that's what we think happened.
EmperorsAlpaca Makes sense.
I kinda wish I could be around for the end of the universe, it sounds beautiful.
A book series by Douglas Adams tells about a restaurant without a roof, somewhere out there, in a distant galaxy, where you dine comfortably to music and candlelight while the end of the universe happens above you :)
Imagine the feelings. It must tear you apart with longing and melancholy.
Wow this was deep
i live it all to GOD.... He knows when the universe will die or vanish...
+Timothy Anthony God don't real
+Paul Sheriff Prove it
+Paul Sheriff Wow, God never responds to me. He just gives me AIDs and colon cancer.
Well I have the answer for you , have you accepted Jesus as your personal saviour???
+Timothy Anthony Jesus? I thought we were talking about the Egyptian god Anubis.
Scientists are now theorizing that even protons will eventually disintegrate into fundamental particles that will reach near absolute zero. Which is to say that, entropy will stop, the ultimate order is achieved where everything is equally balanced.
This is surely the best thing I've ever understood about. THE BEST! Thankyou so much, TEDed!
Wow I'm scared now
Don't worry, you, everybody you know, and all humans will be dead by the time this happens. We good.
dont be cause its not true.
@@raptorzeraora2632 Heat Death is a theory, but it's very likely. Saying it's not true would be dishonest. But, it's fine, we will all be dead, and civilizations might still survive if they can travel to another universe or live in a simulation.
hmm. at one point we also thought the world was flat.
A "flat" universe just means that if you continue in one direction, you will not loop back around to the start point. You just go on forever.
silentzorah thank you for clarifying. now that makes a whole lot of sense. the ultimate infinite
This is one of the few TED-Ed videos that did not say something demonstrably false. Bravo.
However, judging from the comments, apparently the truth is a bit too much for some people. Perhaps this is why the lessons are often dumbed down to garbage.
The dark energy cartoon character is so adorable
wow
Super depressing
Some say the world will end in fire, some say in ice.
From what I’ve tasted of desire
I hold with those who favor fire
But if I had to perish twice
I think I know enough of hate
To say that ice is also great
And would suffice
-Fire and Ice poem by Robert Frost
The one you learn in middle school literature class.
So, if the universe 'ends much like it began'...does that mean that it can in a way 'begin again'? If so, is it possible that we're not the 'first universe' or the last?
Where.....is.....the....universe?
Subhan Allah!
Zayed Ahmed Please don't bring religion into science. They have nothing in common.
Hell doesn't exist
YES I COMPLELYLR AGREEE
Dexter Gestern There is no need for that
Zayed Ahmed They will eventually realize.
Thanks for literally everything, Universe.
Do not be depressed people. I believe that in the future humanity may find a way to spend or convert that dark energy into power or something else and prevent galaxy to expand to its death. Heck, we don't even know for sure that it will going to happen like that. We just foresee it like that with the tools we have right now. In the future we might explore this dark energy and we may even re-invent everything we know at some point and learn what will really happen.
This is a theory I like and can hope happens, it's also not too far fetched
