[@Imagine_Beyond]

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.

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!

[@DIABETOR]

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.

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.

[@echoecho3155]

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.

[@jsbrads1]

Also you won’t save the person, the person will still die and a simulacra, no matter how convincing, will resume the life.

[@perrywaaz3660]

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?

[@echoecho3155]

@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.

[@stevenhetzel6483]

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 KZbin 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.

[@Negative_Clover]

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.

[@innerstrengthcheck]

[@FlavioSantos-uw1mr]

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

I thoroughly enjoyed this exploration of deep time.

[@mackenziebroadbent682]

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.

[@Howl-Runner]

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 still wonder if I'm the same instance of consciousness as before those happened...

I have a question. When we are talking about how fast these eras happened right after the big bang. Are we talking from our point of view or from the point of view of the particles? I would assume that there was some massive time dilation because we are talking about all of the matter in the universe in one spot. If we were like a light year away; would it have been quickly expanding for us to watch or woild it have taken eons to expand?

[@OOL-UV2]

Hit up chatgpt with "does time dilation affect the evolution of the universe?" I've also read that astronomers and astrophysicists have long accounted for GR effects in their work.

[@shinigamisenpai3303]

Astronomy uses something called the "Cosmic Rest Frame", it is the frame of reference where we in rest relative to the "Cosmic Microwave Background" aka when the temperature of CMB is uniform in all directions aka there's no apparent dipole anistropy in the CMB. So, we are talking from the point of view of this "Cosmic Rest Frame".

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?

[@lonjohnson5161]

Isaac Arthur, was the T-scale your invention or is it something like the Kardashev scale and you know it if you are in the right circles? I ask because I'm wondering if I inspired it. A while back (maybe half a year) I suggested using a similar scale (I think I called it the L-scale for egotistical reasons) for characterizing the time element of filters for the Fermi Paradox. It strikes me a plausible that I may have planted a seed, but it is also plausible that the idea is a natural way to view long time scales. BTW, I tried finding my comment, but I'm not skilled enough with KZbin to find it quickly. If in the unlikely event that somebody thinks it important, I might give it another try.

With so many planets, so many scientists, and such distance between them, wouldn't there be extreme duplication of work?

If Neutron Stars last long enough, mining matter from those gives you fresh protons via neutronium decay.

[@User556q]

[@groenendiek]

also the more advanced intelligence gets, the slower time will be for them, as mental processes - organic, virtualized or transcended - are likely to be on a faster scale than we can relate to. How will the fill their time? Eons of it? I think there's plenty of argument to suggest that at some point, a plot is made to quench all life and perhaps seed a new so life can make the journey once again. Perhaps such hard resets are a "thing" that can reoccur every million years or so, possibly leaving a subtle mark that only can be recognized in the advanced stage of a new intelligence.

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.
