‘There’s this mountain of pure diamond. It takes an hour to climb it and an hour to go around it, and every hundred years a little bird comes and sharpens its beak on the diamond mountain. And when the entire mountain is chiseled away, the first second of eternity will have passed.
If it's made of diamond, the bird will deposit more beak matter on it and never chisel away anything. Eventually, you'll have a mountain two hours around made out of bird beak with a diamond core.
During the hundred years the remance of the birds beak would have blown away or have been broken down. There would be a few atoms of diamond taken away every time.
I was gonna live till the very end..... but then I got high woooo woooooo I was gonna take every star in the sky, but then I got high badadada da da da Now im watchin Isaac and I know why! [Why man]....

You are one of a kind Mr. Arthur. You have reignited my fascination with cosmology many times for quite a few years. Thank you for your passionate work.
This is such a great episode! I figured based on the other videos about civilisation at the end of time, that we would inevitably not make it much longer than the blackhole or if we are lucky, the black dwarf era due to the heat death & entropy. However the idea of increasing efficiency with cooling temperatures and the landauer limit is just genius! Thx for the glimmer of hope that there is still a chance for an eternity civilisation.
@@fgklfglhf Don’t be so hasty now partner. That’s a pretty cynical outlook don’t you think? I don’t discount the possibility that you are correct, but it’s much to early to know for sure. You’re underestimating the will of future generations to continue existing, and overestimating our current understanding of the universe.
You need to do a serious episode on the 'aight, imma head out into the multiverse' scenario that you talked about at the end of this episode, where civilizations have had it with this universe and leave it to go to another, similar-but-better universe where it's easier for people to thrive. What methods could be used to find new universes and travel to them? What technology would needed?
@@isaacarthurSFIA Yes sir, found it after you mentioned it a couple years back in a video. Always excited when I get Isaac Arthur story recommendations, because they're always fantastic.
I appreciate the slower tempo and sedate narration beginning in this episode, relative to others. It really makes me think about the time for thought topic.
I think the shear evolutionary pressure to exist beyond time would eventually create a species of incredible fortitude but incredibly slow, having to rely on a super intelligence to ensure maximum efficiency and quick problem solving may also impact that, but if a new universe is born I'm sure they'll have some kind of tech to undo any undesired genetic changes, probably some kind of gene bank containing the DNA of when their kind was at the peak of their evolution, they're also likely incredibly small, $10 they're cockroaches.
In case Isaac reads this, I've rewatched ome of the older episodes and I've noticed something that bothers me in this episode. If proton decay will rend matter apart, how long beyond the natural decay will artificial methods of conservation be able to continue? Speaking of older episodes and speaking... You're doing awesome. The therapy has paid off!
Peasants: We have found a wizard! Burn him burn him! Peasant 1: We have found a wizard, may we burn him? (cheers) Vladimir: How do you known he is a wizard? Woman: He thinks intermittently
All this conjecture of thinking slowly to save energy is only pragmatic as long as there is no competition. If there is, then we got to "Get there firstest with the mostest and don't tell no one were comin."
That question does not work, Isaac will be making since our big bang ( no I did not commit any grammatical errors remember time is it's not a straight line it is a whole bunch of wibbly wobbly timey wimey stuff)
What a wretched existence. Surely by that time they would have been looking at other dimensions, other universes at the very least, there is subatomic also. Having a thought once a gazillion years or so just doesn't cut it.
The problem with any scenario with "brain uploading" is that it assumes human consciousness is effectively no different than computer code. I don't think people understand how massive an assumption that is.
Synapses or nurons or whatever are pretty similar to the 1s and 0s in a computer, as far as I know, so we just need to figure out how to make those copy a brain. Realisticaly I think humans have souls, so we won't be able to create and actual living thing, but mind uploading...... maybe?
@perrywaaz3660 Synapses and neurons are pretty far from 1's and 0's in a computer, though. Edit: to explain what I mean, the 1s and 0s in PCs are literal switches, on and off, which are arrayed to perform pre-programmed tasks. This is far cry from neurons, which, to my knowledge, are more like weird association nodules that attempt to recreate past states to recall, collate, integrate, and create "information." I agree with the idea we have souls, but avoiding the metaphysical side, are we actually sure those electrical impulses are the driving factor of consciousness? Organ recipients report gaining memories and habits from their donor, and kidneys were recently found forming memories. Chemicals, actual physical phenomena, or weird esoteric things could be the culprit. It seems to me that consciousness is far more distributed and messier than we ever imagined. Since we can't even properly define it, I don't think we can upload it.
Consciousness is a committee. You don't have to consciously move your hand away from a burning hot stove when you touch it, the brain knows there's only one reasonable action and takes it without addressing the committee. However if you were told you'd be executed if you removed your hand from that stove, consciousness kicks in, as there are now multiple outcomes. A lot of work has been done that suggests our brains are hosts to multiple different 'consciousnesses', but the YOU than knows YOU are YOU and makes the ultimate decision is what we actually call 'consciousness', and it's just a committee, that weighs the outcomes and possibilities put forth by the representatives living in your head, then comes to a decision. I'm kinda dumb and not super articulate, but that's how I've come to understand it. The 'Blindsight' novel has been mentioned here once, and it's written by a man named 'Peter Watts', who has a ton of great videos on consciousness on TH-cam if you really want to dive in. So yeah, a being who's dead-set on every decision it makes and is only host to one 'consciousness' in it's mind is likely not what we know as 'conscious' at all. It's not necessary.
You're right. Emulating human thought in a computer might be very difficult but maybe not impossible. Capturing the thought processes in living person and transferring them somewhere else doesn't sound very easy either but it's a fascinating subject to explore in fiction.
So many great videos here, so many great series! I must have watched hundreds of hours of Isaac's output at this point. The quality and content is peerless IMO.👍
Thanks so much for all your work here Isaac. You've legit been an inspiration for me getting back into reading and writing sci fi! Which is no easy feat in the smartphone/reels era. Thanks again. :)
I commented about this on the last video and I want to expand on that feedback, the ad placement here works FAR better than in the last episode. I doubt that my feedback had any influence on this but I would still like to give it my praise.
I would think in this scenario it would go somewhat similar to what the Q experienced in Star Trek Voyager. Where everything that could be said, has been said, every possible experience has been experienced and there’s nothing left to do but stare at each other until the lights go out. That’s why my favorite sci-fi is usually something involving multiverses
The energies involved are so small and timescales involved are so huge that quantum effects are going to need to be a very dominate consideration. The noise floor of pure vacuum so much louder than some of the minute amounts of energy being discussed. You could probably just set up an array of superconducting filaments with diodes to harvest stray electromagnetic radiation that is generated from things like proton decay, or even the quantum noise floor itself. Imagine something kind of like a sea urchin or even a 3 dimensional snowflake but the "spikes" or "branches" are superconducting and some of which can be light years in length and thinner than a human hair, all segmented with diodes that connect to a central a core that does the computing.
It makes sense when thinking about an exponentially expanding universe that started from a singularity. That less and less would happen over time. The universe starts with a bang but it ends with a such little energy that all of spacetime no longer can support it's existence. What happens after that? That's the premise of this video. How could life persevere. This is such bleeding edge conjectures about questions we don't even have the imperial evidence to ask. Issac doesn't have a lot of hope to stand the test of time with his futurist theories but I think even he would admit this video is among the least likely to remain correct under the incredible breadth of spacetime.
4:30 the human mind seems to work on a nonlinear scale similar to the logarithm. Once some measure or count becomes "big", it just stays "big" even if you add a lot more to it.
At 42:26 mini black holes are mentioned in the context of structures that'll last eternity. Does that mean you can make matter out of mini black holes and if so what would it's properties be. Wouldn't mind seeing a video on that.
Love this stuff, i dont know if snyone see the animated series Pantheon but it involves some of this stuff. Awesome series about man uploading intelligence.
I think the more interesting question might be what such a civilization have to "live" for? there's literally nothing that can be the goal for such a civilzation's existence
A splendid Arthursday video. Only SFIA can plan and contemplate such staggeringly long-term visions of the future compared to our short-sighted contemporaries. I do hope to live to such times.
Three problems for the ethernal intelligence: 1. eventually the energy expendeture will drop down to single quanta of energy thus all the supply will have to be spent at once and not a half of it. 2. accelerated cosmological expansion creates an Unruh-Hawking radiation emission from the cosmological event horizon, thus the background radiation temperature will have finite positive low bound and temperature dependant Landauer limit will have an upper bound. 3. Computer system cannot cool itself below the quantum ground energy state which is finite positive level even if problem-2 is relaxed. I wonder how could Dyson (one of the founders of QED) had missed those problems ?! PS: ethernal intellighence feels dead most of the time. It is a slow eutanasia.
You probably run to those problems first, but even if you go past them, cold fusion to iron includes not only your fuel reserves but your computer too. You'd need to constantly repair it and the monitoring system might use up more energy than it's worth.
@@phdnk Every once in a while, quantum tunneling causes random atoms to spontaneously fuse. This produces a little bit of energy, which could be harnessed to sustain life, which I think Isaac mentioned in this video. Unfortunately, these random atoms could also be parts of the computer than runs your post-human civilization, so it would be slowly killing you. I just mentioned another problem in addition to the ones you wrote about.
Great show. I think it's more a question of whether you can eliminate intelligent life once they are established. Intelligence will persist unless physics demands it's end.
Over the decade and more you have grown as a representer of this sciency stuff. over the last decade we too as listeners have grown. some less and some more. many like me for a decade already. as a chemist cum biologist i appreciate this stuff. 'tis comfortable to listen to
What I find most amazing is that really large black holes could result from superclusters of galaxies decaying and colliding. These things could have trillions of solar masses and would gain mass via absorption of background radiation faster than they would lose it over a MUCH longer period of time. When we talk about things that log is not enough to summarize the distance everything gets a bit confusing
What do you think of the theory that what we think of as "Gravity" is just the action of Inertia on an object in a gradated time field, where time is moving more slowly near clumps of matter, so objects, through Inertia, are accelerated toward the matter, by virtue of Inertia trying to maintain their energy state relative to their position, mass, etc? Thus, it's not a "Force" as such, but simply Inertia in action.
The logarithmic scale puts things into perspective. Star-lifting with its life extension for the stars sounds good until quadrillions of years aren't enough anymore. Feels like calculating the expenses for Mobile Legends skins haha - Adûnâi
The time between thoughts make it an intelligence so foreign we may neither come to knowledge of its existence nor converse with it on time. Thus intelligence itself is a frivolously founded term.
I thoroughly enjoyed this exploration of deep time. With the new potential theoretical reality that dark energy isn't real and the perceived increased expansion with distance is relativistic time dilation in voids vs denser areas, it would be fun to see your take on surviving as long as possible in a "big crunch" universe if that's the future.
If a civilization at the end of time could build a vessel that could exist past the big rip, where would that vessel be? If the universe has evaporated, is this vessel now sitting in the true vacume? the space the universe existed in? If so, could they just travel in a straight line to another universe? If they are sitting the space where big bangs happen, where you could watch a big bang happen, could they fly to another universe? Would they be able to get in?
Reading 'First Contact' by Raltz again. "There is only enough for one!" Then of course because it's a HFY story (or series) the humies break that rule.
i think that by that time, if a civilization manage to live right past the moment when most of the stars died, most likely will have the technology and understanding to create a new Universe
I think other universes, younger or just starting out, could be found and accessed. Or a civilization could conquer space and time, preventing the demise of this universe.
This video made me think about the matter and anti-matter imbalance. Maybe they did appear in roughly equal amounts and interacted. Perhaps the difference is their stability
The first thing our descendants must do to extend their time and energy is to manage the merger between the Milky Way and Andromeda. Left to its own devices, the smash-up will cause a rapid burn through the reserves of interstellar gas and accelerate wasteful star formation and calamitous super novas. We must tweak the motions of the two galaxies as they fall together, creating a long-lasting giant spiral instead of a quickly red-and-dead elliptical. That move alone will add a huge amount of functional time to our galaxy.
There are times when I have wondered if dark matter is actually somebody *already* arranging stable but energetically useful matter for the long term...
The added fuel would still be here. I’m not complaining about getting all that. Also we can be a galaxy wide civilization long before that happens and we can each protect our local stars for the “collision”. Maybe even seal all our stars in Dyson spheres and even hop across the gap when they get closer and Dyson seal all their stars too, long before their stars touch our interstellar hydrogen.
@@DoubtfireClub someone did that with out paperclip maximizer episode, for every time I said paperclip, I warned them there were 200+ uses in the episode and their liver might be shot by the end :)
I wonder if it's possible to encode information on the quantum foam itself. Digital "devices" built on that basis could, in principle, last forever, but they would require a way to reverse entropy within them.
Perhaps that's what took place before the beginning, it all cooked and slowed down to where thoughts dissipate. That which was before waited for that very moment when all of universe and reality was at its thinnest, it's slowest. And just before those final motes winked out forever. That which was before, became.
I feel like the answer to the fermi paradox is simple. Species figure out quantum entanglement and grow past our physical existence before we figure out faster then light travel
If we forget about our tradition view of time and see time as a timeline of particle interactions then we are already a civilisation at the end of time
Sometimes I like to existentially worry about the distant future, then I think about how much scientific knowledge we’ve accumulated in only a few centuries of doing science and how our understanding of reality has been uprooted on multiple occasions. So then I think in a few centuries our current predictions of the distant future will look hopelessly quaint and ignorant. Or maybe we really are approaching the end of science and we’ll never get FTL or entropy breaking machines.
yeah but that's assuming that all technology will stagnate to such a degree Clark tech will not be able to open a gate way to a created universe, or something that we can not even able to have the concepts to think of, the way Neanderthals did not have the concepts to think of a atomic bomb, and it's billions of times worse then atomic bombs are to Neanderthals.

Over the decade and more you have grown as a representer of this sciency stuff. over the last decade we too as listeners have grown. some less and some more. many like me for a decade already. as a chemist cum biologist i appreciate this stuff. 'tis comfortable to listen to
What I find most amazing is that really large black holes could result from superclusters of galaxies decaying and colliding.
These things could have trillions of solar masses and would gain mass via absorption of background radiation faster than they would lose it over a MUCH longer period of time.
When we talk about things that log is not enough to summarize the distance everything gets a bit confusing
What do you think of the theory that what we think of as "Gravity" is just the action of Inertia on an object in a gradated time field, where time is moving more slowly near clumps of matter, so objects, through Inertia, are accelerated toward the matter, by virtue of Inertia trying to maintain their energy state relative to their position, mass, etc? Thus, it's not a "Force" as such, but simply Inertia in action.
The logarithmic scale puts things into perspective. Star-lifting with its life extension for the stars sounds good until quadrillions of years aren't enough anymore. Feels like calculating the expenses for Mobile Legends skins haha

In the grim dark future there is eternal intelegence
The time between thoughts make it an intelligence so foreign we may neither come to knowledge of its existence nor converse with it on time. Thus intelligence itself is a frivolously founded term.
I thoroughly enjoyed this exploration of deep time. With the new potential theoretical reality that dark energy isn't real and the perceived increased expansion with distance is relativistic time dilation in voids vs denser areas, it would be fun to see your take on surviving as long as possible in a "big crunch" universe if that's the future.
All shall end.
If a civilization at the end of time could build a vessel that could exist past the big rip, where would that vessel be? If the universe has evaporated, is this vessel now sitting in the true vacume? the space the universe existed in? If so, could they just travel in a straight line to another universe? If they are sitting the space where big bangs happen, where you could watch a big bang happen, could they fly to another universe? Would they be able to get in?
Will this affect the glorb prices?

Reading 'First Contact' by Raltz again.
"There is only enough for one!"
Then of course because it's a HFY story (or series) the humies break that rule.
Ah, the standard "million million million million million" scale of an Isaac Arthur video

1st always enjoy your posts.
You were first lol
Glad you enjoyed it!
i think that by that time, if a civilization manage to live right past the moment when most of the stars died, most likely will have the technology and understanding to create a new Universe
I think other universes, younger or just starting out, could be found and accessed. Or a civilization could conquer space and time, preventing the demise of this universe.
Could you do a video on the possibility of a universe before ours?
Reality: All things will end nothing will be left.
Intelligent life: Nah I'd win.
Dyson was wrong, the alarm clock to wake up from the pause is not trivial.
This video made me think about the matter and anti-matter imbalance. Maybe they did appear in roughly equal amounts and interacted. Perhaps the difference is their stability
I'm raw-dogging this episode....no drink or snack
The first thing our descendants must do to extend their time and energy is to manage the merger between the Milky Way and Andromeda. Left to its own devices, the smash-up will cause a rapid burn through the reserves of interstellar gas and accelerate wasteful star formation and calamitous super novas. We must tweak the motions of the two galaxies as they fall together, creating a long-lasting giant spiral instead of a quickly red-and-dead elliptical. That move alone will add a huge amount of functional time to our galaxy.
There are times when I have wondered if dark matter is actually somebody *already* arranging stable but energetically useful matter for the long term...
The added fuel would still be here. I’m not complaining about getting all that.
Also we can be a galaxy wide civilization long before that happens and we can each protect our local stars for the “collision”. Maybe even seal all our stars in Dyson spheres and even hop across the gap when they get closer and Dyson seal all their stars too, long before their stars touch our interstellar hydrogen.
Economists: In the long run, we will all be dead.
Astrophysicists: In the long run, we will all be waste heat.
0:01 you can skip to 14:25 That's when the video really starts.
Can yo tell me where do i can eat the snak and drink?
@yaomingas5425 you turn it into a drinking game every time he says "T" something time dilation Wibbley wobbly .take a sip of your beverage.
@@DoubtfireClub someone did that with out paperclip maximizer episode, for every time I said paperclip, I warned them there were 200+ uses in the episode and their liver might be shot by the end :)
I wonder if it's possible to encode information on the quantum foam itself. Digital "devices" built on that basis could, in principle, last forever, but they would require a way to reverse entropy within them.
Perhaps that's what took place before the beginning, it all cooked and slowed down to where thoughts dissipate. That which was before waited for that very moment when all of universe and reality was at its thinnest, it's slowest. And just before those final motes winked out forever. That which was before, became.
I feel like the answer to the fermi paradox is simple. Species figure out quantum entanglement and grow past our physical existence before we figure out faster then light travel
reminds me of the star trek “death wish” episode where a Q wants an end to his eternal life
Quite the journey.
Sir. Was blood in the Universe 🧐💭 Great Program 👍🏾 thanks for sharing Sir.🙏🏾
Looking at the USA i would say we move into the eternal stupidity direction.
If we forget about our tradition view of time and see time as a timeline of particle interactions then we are already a civilisation at the end of time
Cosmic Science and Metaphysics is always so interesting to study/learn about. Cool video.... though, why is it in German?
Intelligence, uh, finds a way.
Oh I love this! The Prime Presence - Player Character of reality doesn't stop existing, thus eternal intelligence. We are its eternal onion skins.
Sometimes I like to existentially worry about the distant future, then I think about how much scientific knowledge we’ve accumulated in only a few centuries of doing science and how our understanding of reality has been uprooted on multiple occasions. So then I think in a few centuries our current predictions of the distant future will look hopelessly quaint and ignorant. Or maybe we really are approaching the end of science and we’ll never get FTL or entropy breaking machines.
The hardest part is to store enough snacks and drinks to last till the end.
yeah but that's assuming that all technology will stagnate to such a degree Clark tech will not be able to open a gate way to a created universe, or something that we can not even able to have the concepts to think of, the way Neanderthals did not have the concepts to think of a atomic bomb, and it's billions of times worse then atomic bombs are to Neanderthals.
Are you taking into account how much energy loss windows updates be responsible for?
