New Interpretations Suggest the "Heat Death" Hypothesis Might Not Hold (2023)
Original: New interpretations suggest the "heat death" hypothesis might not hold (2023)
Key topics
The notion that the universe is hurtling towards a "heat death" has sparked a lively debate about humanity's long-term prospects, with some commenters arguing that our species is uniquely positioned to defy extinction. While some, like delichon, suggest that humanity's capabilities set us apart, others counter that we're just one of many species that will evolve or persist in some form, as oneshtein notes that we're evolved from 1 billion-year-old bacteria that still exist today. The discussion takes a humorous turn with qgin's tongue-in-cheek suggestion that we're just a screensaver on an extradimensional office worker's computer, but others, like Trasmatta, point out the "existence fallacy" - the assumption that it's better for humanity to exist forever. As the conversation unfolds, it becomes clear that the thread is as much about our collective values and biases as it is about the fate of the universe.

You're right. It almost lost me with this nonsense
>Pi to the last digit? A triviality
Cool stuff though
Although, *spoiler*, my mind is still having a hard time understanding how the characters could exist before their simulation started.
Did they just not realize that their reality was sped up before the moment where the simulations began?
It's a common response to any interest in the destiny of humanity: "what's so special about humanity? What about bacteria, huh?"
I don't know, I'm human and humans tend to be social and interested in their own species? Is that weird? Does that not apply to you? Do you consider it petty and parochial to be more interested in one's own species? Are you "above" that?
If any bacteria or humans are interested in projecting the future of bacteria and their probability of surviving humanity, they should absolutely go for it.
Even if something from earth lived that long, it wouldn’t be human. It probably wouldn’t be remotely recognizable!
Highly recommend reading this book for how these sci-fi theories are being used to promote eugenics, climate destruction, and pseudoscience: https://www.amazon.com/More-Everything-Forever-Overlords-Hum...

As long as you're sticking to the well-established stuff, it tends to be quite factually accurate. I think it's really underrated as a resource for good high-level overviews of fields where those overviews otherwise don't exist at all, are overly technical, or the existing overviews have a lot of author bias.
I'm talking about general overviews of topics, where a good book form at the level you're looking for often doesn't even exist.
You're talking about a classic book that is recognized as a great work.
Nobody's claiming that what ChatGPT outputs is Cosmos. And most books written by people aren't Cosmos either.
And most of the time when you want a basic factual introduction to a field that is at your level, neither too popular nor too technical, ChatGPT is really good at providing that.
Not everything has to be Cosmos.
Four Laws That Do Not Drive The Universe, The: Elements Of Thermodynamics For The Curious And Intelligent

Maybe it's just a problem of being loose with terminology, but this seems to be contrasting entropy and information content, which is backwards?
Both have low information. The complexity rises and falls, peaking somewhere in the middle, as energy from the gravitational field is turned into structure.
https://en.wikipedia.org/wiki/Weyl_curvature_hypothesis
Penrose likes zero initial Weyl curvature because it provides low entropy, but also conformal flatness, thus enabling his CCC theories.
Another consequence is that the Big Bang is not a reversed black hole (white hole). Black holes have high Weyl curvature. The Big Bang is the lowest entropy configuration, but a Black Hole is the maximum entropy configuration (just mass, spin and charges).
Those are evolved traits, and it seems more likely that evolution will replace them with some other traits within a time frame that will be like the blink of an eye compared to the projected decay of the universe.
The only problem for earth life is that anything less intelligent than a human cannot leave the planet with significant chances of survival. Bacteria can however take a ride in our space probes and get a minuscule chance to colonize e.g. Mars [1].
What will go to the end of the universe is self-replicating robots. We have already made the first step in that direction with the AI that makes the headlines currently.
No art, no love, no dreams, just brute force.

will end as well since this kind of situation changes the orbits. So energy for life and usable thermal gradients will disappear even if entropy will continue to increase for a long time -- for instance, black holes will be slowly inspiralling and crashing into each other resulting in huge entropy increases on paper.
A later (set?) of chapters might just be in the 90+ scale; at that regime the characters can flit around the universe in the notional blink of an eye, even though their nanoships' velocity is only a few km/s. In my mind it'd be just a nuts-and-bolts 30's-style hard boiled detective story; but, set in the year 10^110.
Oh! Oh! And Charlie Stross would write this book for me, and it'd be a series.

Sounds like Stephen Baxter's cup of tea. Hell, the detective could even be Reid Malenfant himself (maybe a cameo for Sheena 5 in a later book in the series?)
Then again, if there was an ultradeep-time Saturn's Children book, I'll place the preorder so fast it'll be blueshifted.
That's all assuming we can't "break physics" and nucleate something new, find a tear in our current manifold, etc. Our peon brains are too small to reason about this and any claims that we're stuck are insufficiently computed.
Given our limited sensing capabilities and tiny time sample, I'm skeptical of our current understanding. Claims of current model predictions feel premature.
I never heard something like that. Gravity follows the first and second laws of thermodynamics.
I don’t know about that but it’s also sometimes described as an entropic force https://en.wikipedia.org/wiki/Entropic_gravity
Wake me up when dark energy is more than a statistical anomaly, or we have a practical theory for a warp drive.
Anyway, its true that something he calls the complexity increases forever in his more recent models, this is just an expression chosen to make the dynamics work out. Even Barbour says this is not necessarily related to the sort of complexity life has. And it depends on the universe being an open systems.
