Civilizations at the End of Time: Iron Stars 

Isaac Arthur - Great video again as usual. I have a few comments. It is unlikely a quantum event can take place within a non-quantum state like a large brain or person popping into existence, or so I've been told (I didn't follow the math, but that was the conclusion). I've had an idea about the future where instead of billions of people there are just a few, highly advanced and god like. The question here is why would you want trillions of people living at the expense of everything else? The next question is not - are we living in a Simulation, but can this Universe/Existence be simulated. In other words lets assume the universe we live in is real, now can it be made into a simulation...can we make an experience within it that is impossible to tell whether you are in the real world or not? If the answer is yes (theoretically) then we have to conclude ALL reality is a simulation. The key word here is (all)...there is no such thing as real, the simulation is "Turtles all the way down". Consider the old stories of Atlas holding the sky up, and Earth supported on the back of large animals, we now know none of this was needed. If a super intelligence had all of time to experience, what would it do? How to avoid getting bored, and how to duck infinities? You do this. Of course if the answer is no, and a simulation to the extent of duplicating this Universe is not possible, then the universe must eventually end. Time ends when there are no more events. Have a nice day.

I don't understand how anybody would find it difficult to understand you. You don't sound like you have a speech impediment. You sound like you have the accent of an Israeli who's lived in South England for about 5 - 10 years. Your accent is really clearly comprehensible to me.

One thing makes me wonder: If pulling quarks apart can generate new quarks would this effect make it possible to repopulate the universe with matter maybe even in a sort of a Big Bang at the end of times? /edit: oh Nevermind... just scrolled through the comments after finishing the Vidya..

It is a shame that this kind of errors were easy to solve with youtube´s annotations back when you did the "first part" of this "...End of Time:..." mini-series [but is not posible now due to limitations on the side of smartphones blocking this "feature" to avoid people using PCs to watch youtube as it is easier to block advertisement].

@ *Mikolaj* : . Ni-62 may be the one with the "denser" nuclei; but that does not mean it is the more stable. . The kind of "ending" Iron Stars experience is the one were quantum tunneling allows for adition/substraction of protons/neutrons [causing decay of heavier cores]; or the fusion of two cores (generating a heavier element that later decays again). -> Because the fusion of Fe-56 (either with another iron nuclei or anything else) absorbs more energy than what it releases, it means this excedent of energy inside the resultant heavier element would eventually come out through spontaneous fission (decay) faster than what random tunnelling could keep creating things heavier than Fe-56 [as there is a net loss of energy carried away of the mass through photons or neutrinos].

Yay! I have autism too and would have loved if someone did something like this to me when I was younger

Comment deserves a heart if Isaac sees this.

@Historystuff They find social interaction extremely challenging, and tend to avoid it if possible. They tend to have tonal control issues, and trouble reading other people's emotions. But find a topic they like, and you can bring them out of their shell. Autism still isn't fully understood, it's a disorder on a spectrum, and one that's somewhat treatable with cognitive behavioral therapy. Some autistic people you can hardly tell, and others are fairly obvious.

@@cjaquilino how would a heart change literally anything? I’m just happy for the guy, his nephew could be very smart in his future!

@@daka3785 It would confirm Isaac read it.

Isaac's entire channel is drenched in ideas for a scifi story to grab on to, some of the theoretical even plausible projects he talks about make Star Wars look surprisingly quaint even when they have FTL and super powered compact power sources, heck, a Nicol-dyson Beam could prolly tear starkiller base a new one, without even burning up a whole star in the process, even speed of light limitations isn't so bad if your just a uploaded digital copy of yourself that can play with their perception of time while exploring the galaxy making copies of yourself time to time. TLDR I want to be Bob from "we are legion, (we are Bob)" and the more SFIA videos I watch the more reasonable and fun that sounds

Theoretical Scientist: don’t mind if I do...

Not that this will be a possibility in my lifetime, but if it was, I wouldn't do it. I'm a soul scientist. I don't support clones, teleportation or mind uploading. Replications of me are not me. I would die and my body snatcher would live.

@@elias_xp95 I wouldn't mind. Its an alternative form to keep life going but this time at the advantage of the life lessons and wisdoms acumulated in my life time. You know how valuable that is? We set up entire schools for it and have philosophies made out of it. Why spend lifetimes educating ourselves and gathering wisdom when you can bookmark it, like a presige thing in those game, and have your coppies pick right up where you left to become ever more wiser and intelligent. Given that you have a good set of manerisms, belifs, a good head on your shoulders, and a plan to live on and survive against all thr odds be that whatever legacy that may manifest from you.

@@helium-379 "Its an alternative form to keep life going but this time at the advantage of the life lessons and wisdoms acumulated (sic) in my life time." But that's just it. You would keep *"life"* going (as a biological clone) but *you* would be dead. So what would the point be? To continue to be a drain on resources, getting in the way of the younger generations? Forcing them into low ranking job positions or (dependent on scarcity) ration queues and studio apartments, heck think of the traffic jams!? It would be the replica that continues to exist. A body snatcher. Not you. At the very least a mind upload into a computer would seem the more ethical. A digital version of you would just be a smart library. Live, have children, upload your mind to a machine, die, continue to share your knowledge and wisdom with those who come after. But the pursuit of such methods for ones selfish greed of an undying life seems to me to be hellish, dystopian and at worst immoral.

@@elias_xp95 I said that the life that lives on is a legacy. If I cant live on myself then its better to have a version of me that completely understands who I am and what my goals are. Simply telling people will get everything lost in translation and that last thing we need right now is another stupid prolonged telephone game. This is never about "living forever". This is about pushing the limits of what we can create with tools we have invented. We have the tech to clone people already. We aren't doing it right now since its unusual and governments aren't interested in funding it yet. All that is left is to figure out how to copy memories accurately with little to no compression. There will not be any scarcity in the future when we are looking at this long term. You underestimate how vast and gigantic the universe is. It would take hundreds of trillions of years to use up a tiny percentage of what is out there. So small that the universe will die before we will ever manage to touch a quarter of it. We haven't even mined out all the resources on earth yet and there is still plenty of space for people to live on. The only problem is that no one wants to live at those unpopulated areas which happens to be most of the land on Earth. Also stop trying to vilify our future humans. They did not snatch any fucking bodies. Their bodies will be their own grown from vat tubes. The only thing they they will have from the start is all my memories including the understanding that they are clones that must work together so we can finally go to fucking space. I don't care if they are tin cans, meat bags, or meat cans. It bothers me none that they are exact replicas of me. How is any of it greedy when the whole purpose behind it is to pass on knowledge and wisdom with the least amount of compression possible. So that our future incarnations repeat or mistakes less and less. So that they may be more just in their judgements. So that they adapt when needed and preserve whenever it is best. So that they can be infinitely more wiser and intelligent than they were. Life is always dying and it is always living. To end it all is also futile since some other beings will take our place and there is no death without life. Be it in this universe or the next one. So why not be us? Why can't we be the ones to take the shot at escaping the heat death of the universe? You just want to throw in the towel now when we are at the highest peak society has ever seen? Yeah sure there are tons of bad shit. So what? Its been like that for tens of thousands of years and guess what? We went from apes in trees to apes in homes made out of trees. There is no telling how we will end up but we must keep pushing on. That is the thought that is as old as the first ape that chose to walk the savannas. They probably died a violent death but look at where they got us. Have fear in the present but show none in the future.

That is my new favorite quote.

That's how FTL will really be invented. "Just get to the speed of light, then go faster". Jeremy Clarkson is going to be their god.

@ungratefulmetalpansy woossh

I have the same impediment with R, S, And Thr too

I suffer from a lisp himself if that counts.

I always find it weird when a RU-vidr says something like "I'm not going to go into details because this video has become already long enough and nobody would want that" or something of the sort, then I check the length and is something like 15 min video. Yet there are many videos and analysis that are literally hours and still have millions of views so there is a demand for longer videos. If a RU-vidr is worried that adding few more minutes into already not very long video is going to make people click away, maybe the presentation is the problem, not the length itself. It's like how some 2 hour movies feel like they're dragging on, but people watch LOTR 3+ hours extended edition and feels like an instant.

yes, it sounds like a different accent of british english.

His pronunciation of "R" improved big time! It's apparent he's working on it hard.

I was just thinking "I like the quirky way this guy talks" when Elmer Fud appeared and floored me.

To me its just a cool weird accent. Tho got me confused on iron-ion.

as speech impediments go it's not too bad, first 5 minutes I just was wondering where he was from because I couldn't place it as an accent at all ( I'm actually quite good at placing geography based on accents)

Why? You won't be around to comprehend it.

@@rakino4418 games!!... videooooooosss.. e maillll...

Yes, but it wouldn't have any "continuity" with us, as in, there won't be a unbroken thread of events, space, and/or consciousness connecting us to them. However, you may have a way around that continuity issue depending on your personal philosophy. Whenever there is a break in our consciousness, like sleep, or anaesthesia for a surgery, or any other instance of unconsciousness, how can we be sure that the person who sleeps is the same that wakes up later, and not an identical copy, or a new mind with the same memories as the previous'? That is a similar issue to ours, and if you aren't bothered with this continuity question on these cases (I, personally, am not), then yes, one can say that it would "remember" us, in the common sense of the word.

Plot twist: the name of that Boltzmann brain is Azathoth and other Boltzmann brains make fun of his silly dream

Yes but there will be equal chances for a boltzmann brain to remember a fake made-up history of us (or I dunno, star wars or something), and they'd have no way to tell which one was real

There would have to be a chance of that happening, and there isn't. Boltzmann brains form AFTER the dissolution of energy, and since you need energy to store information, the information itself would no longer exist by then. Technically, it IS possible for them to have "thoughts" that we couldn't distinguish from a remembrance, but that would actually be random chance

There is a chance it could form before humanity's extinction or it could for as a environment that humans could live in allowing humans to survive a small bit longer

Robert Weiss his fucking accent made laugh my ass

Of course. We are but a primitive species on a small rock. At the very least, our understanding is incomplete. None of the models we have factor in the possibility that we leave our home, establish a massive, technologically power interstellar empire, and break or revise the laws of physics. Perhaps we can jump into a younger universe. Perhaps the Heat Death is wrong, and the universe stops expanding. Who knows?

It's just that everything we believe is true would break. And that is very inconvenient. But could very well be that our current math is not enough, or cannot explain what is going on. Hence we get these "impossibilities" that might not be impossible in reality. But there is no such evidence of that so far, so it just becomes an inconvenience.

@Ajay Singh You might benefit from Bertrand Russel.

"Laws of Physics" LMAO -From an Astrophysicist

@@nighthawkviper6791 The laws of physics are little more than neat suggestions based on old data.

Have you ever read the Xeelee Sequence? It was very speculative, but one of the books (Exultant, IIRC) depicts a history of life in the universe, beginning with intelligent life made of space-time defects in the first moments, followed by intelligent life made of quark soup in the first few minutes.

Yes I had the same thought when he was talking of the Big Bang as fast and now as ‘normal.’ If the Arrow of Time is experienced slower in the far future, how fast was it experienced in the past even closer to the big band. Would intelligence have time to exist and perform even one operation before time was already gone because it was moving so fast. Short of random quantum fluctuations, is there a minimum measurable time or level of disorder needed to form intelligence?

This could become relevant. Isaac Arthur speculated that over this long time we might be able to figure out how to move to newer, younger universes. If there are infinite universes then we could become eternal universe hoppers.

Uh....no.

Nebroski Theraut give an infinite universe enough time and anything will come to exist. That’s the core principle he’s referencing.

can you imagine such a poor creature, waking to consciousness in a cold sea of darkness and chaos, with no companionship, no history, no concept of language, just thought, just wants, just needs... the first few would die horrible lonely deaths... if a few were unlucky enough to survive in a configuration that allowed them to thrive in such a world, my guess is they would promptly learn to just sleep, and dream... this brings to mind such alien horrors like Lovecraft wrote about... then again, the Christians do say that 'in the beginning there was the word, and the word said: let there be light... that sounds like a boltzmann brain to me, and we could all be the dream of god, created because it is so unspeakably lonely and unfulfilled without us... then again, the vedas speak of the center of consciousness as being pure bliss, therefore we might be the idle fancy or lovingly crafted artwork of a being exploring its reality and its imagination... then that would paint a more benign picture of a loving god... but considering that babies are starving and dying the world over, we may be living in a sim that has been abandoned, or we might not be the focus of such an intelligence, or this world is real and chaotic and merciless... for what meaning could there be in the death and suffering of so many innocents? hold on, i need more coffee...

@@Nefylym read the first verses of Genesis. What you describe is basically that...

That's essentially the Omega Point hypothesis in Roman Catholic theology. Those Jesuits who subscribe to this hypothesis tend to be fairly progressive and harbor transhumanist, techno-utopian views since they believe we become God and God creates us.

"we" as in the conscious elements of the universe. The tiny pieces that have come together in just the right way to think about themselves. We are just a tiny fraction of that wider family. "we" will always exist in some form or another, weather it is just a byproduct of the laws of reality or some intended consequence of existence.

In the future I will become we. Take my great great great great grandfather. He was one now I have 1,000+ 4th cousins, so now he is many.

I mean there's mind uploading maybe ¯\_(ツ)_/¯

underestimate the endurance of the thread of life

That's why it will be so hard to run into other advanced life forms. Sure, alpha centauri probably does have life.. oh, (as an example) but sadly they all died out (or became pure energy or whatever) 3 billion years or so ago, so all their tech would have eroded to dust long ago. In all likelihood, interstellar ally civilizations will have to be almost purely mechanical to interact in any meaningful time frame.

Damn, I thought I was alone! Rock on brother I think the same way

Time and or rate of time is not a constant in the universe, By this i mean time can be affected by the warping of spaceTime. Yes space and time are one and the same and how we know this is through Einstein's theory of relativity that teaches us that mass and or a large collection of matter can warp space time. We know this to be true also for rate of speed relative to say the Earth. If i travel at the speed of light away from the Earth for a month and then return. A month will have past for me and 200 years will have passed for earth. Mind blowing fact is depending on the mass of your galaxy that you live in say compare to a smaller galaxy. Time will pass slower in a large galaxy then say a smaller one based on the mass of each galaxy and its ability to bend space time.

... and righly so! All-encompassing cessation is the only thing keeping me vaguely sane. It's hard enough dealing with the threat of reincarnation ("souls" aside). I don't have a perfect life, but I'm profoundly grateful that I'm not experiencing the lives of most of the other 99.99999% of organisms on the planet. Some minor examples: zombified ants whose brains are rewired by flukes; insects paralysed and used as vivisected incubators for hatching spiders. Millions of farmed pigs whose despair is so complete that they break their teeth trying to bite through their cages. Billions of hopelessly injured creatures doomed to a slow and painful death. Trillions of lifeforms dancing on the razor's edge of bleak survival, under total command of the nonconsensual reflex to perpetuate it. That nonsense _really_ has to stop. It's not just a senseless and cruel tyranny, it's outright psychopathy. It's almost as depraved as peeing on a rug that really ties a room together. You say the best death is the unfelt death. Agreed-the same is true for life, in almost all cases. I'm all for the living and extension of lives without egregious suffering, but they comprise a vanishingly small amount of life on Earth and, by extension (assuming biospheres with quadrillions of nervous systems aren't freakishly rare hellscapes), the cosmos. So, the end of life gets my vote as the singular compassionate transition. (Even better, if unrealistic: plants. Everywhere! TRANSGALACTIC FIELDS OF... POPPIES!!!)

Hi Boltzman! Hope you’re having a happy existence if you’re thinking of this!

Wouldn't that qualify as a sort of deity?

There's a thing which states as Boltzmann brains make up 99.9999999999999999% of all living things then we are more likely to be Boltzmann brains than not.

But if a Boltzmann brain can come into being with every possible memory, then that itself means that those memories are effectively useless, since there is no correlation between those memories and the real events that happened before it. Meaning that even if a Boltzmann brain came into being with memories of everything that happened prior, it would have no way of knowing that they were true.

You're talking about the hypothetical Big Rip, which can't happen in our universe.

Wouldn't that brain die immediately? At that point the universe will be chaos, sure, but it'll still be chaos at a fraction of a kelvin and would die immediately from the cold. Another big bang would have an exponentially higher probability of happening

MetraMan09 well u said the vast majority are stupid and incapable not all of them

@@tomtoms8480 stop using a(s) where they dont belong

@MetraMan09 damn and my friends say I hv a genius iq. Looks like Arabic to me

I'm sure Kek will deliver /brother

More like "The Night that Never Ends"

Leon de Rozan I agree.

I couldn't help but experience a manly tear when he said it. :') After a number of years that is greater than the number of atoms in the _entire observable universe_ has finally passed, we return to our roots. Ironical, really.

Leon de Rozan and yet we'll continue to live for a near eternity after that.

Thanks!

and he does it weekly too

just gonna say hi Cody, so that if Isaac comments I'll be notified by Google

:) It's probably the fiction focus, I'll be happy to shoot you my contact's email if you like, and yeah the notion of the Big Rip resulting in a ton of new matter is a bit of mindscrew, particularly considering that while our observable universe came from a finite or even infinitesimal spot, the rest of the universe over the cosmological horizon might have emerged from an actual infinite space, so we could just have loclaized big bangs going off every so often. Totally destroys conservation of energy but then that's already iffy under general relativity and almost dead under Dark Energy.. I think Kurzgesagt's dropped the ball on that, we all do sometimes, but there's a speed they travel away from us at and if we can send ships faster than a given galaxy is flying away we can catch it, albeit with time to settle worlds in between and with a journey taking a really long time there is going to be a max redshift people just say 'nuts, too far' on, and I tend to figure a billion light years is probably about it. Maybe half, maybe double, but if you cna colonize any other galaxy besides our own there's no limit to the Local group.

Wow! Two of my favourite youtubers having a conversation. I didn't expect to see that. I would LOVE to see you guys colaborate in some video. Please think about it! Love your stuff!

Isaac Arthur I really appreciate how much time you take to read and comment on your audiences questions and love for videos. Thanks and keep up with the great work.

Yes audible does work much better on your channel than mine. I'm glad you got the deal; a channel like yours is well deserving of it.

Does time even exist outside though?

it doesn't exist time is an illusion what is the substance that spaces between universes though and how permeable or transversable is it?what if the universe humans escape to is completely untenable or has completely different conditions that make it impossible to occupy or exist in?

@@morphingfaces I know.

yeah your question is interesting edin743 what would a universe in which it is impossible to impose a time space frame work on spacial experience entail?

@@morphingfaces I don't think a universe without entropy could exist, or at least it wouldn't be alike what we consider a reality

I was wondering if I was the only one... not in this community.

Mind = Blown

What?

He's saying that our universe could be just a larger boltzmann brain.

Lion Bright but at the same time it's not possible.

that is indeed a possible mode for the multiverse, singularities pop out of literally nothing and undergo inflation into a full universe

And for every week to come; hopefully until the heat death of the universe. :-)

me too

Jason Toddman by then his videos will be released every trillionth Thursday.

What is Arthursday?

It's a mix of Isaac "Arthur" and "Thursday" which is the regular schedule for him to upload a new video.

Best place to eat breakfast, and if you're still hungry, why not swing by the Big Bang Burger Bar for a quick lunch.

42!

Welcome to McSpaceys, would you like to try our special today, its the Big Blac Whole. xD

By the time we get to a billion years. We would no longer need sustenance. More than likely , we would likely be biomechanical. As that would likely be about the way to live long periods of time, while also maintaining humanity, without becoming a completely machine civilization.
