We're doing a pretty bang up job of making that one second as stupid and painful as possible.

I just had a moment of what is everything

I don't know how to explain it but from nothing to something to nothing again but no why

Tangentially related great sci-fi short story: “The Last Question” by Isaac Asimov: https://users.ece.cmu.edu/~gamvrosi/thelastq.html

Thanks for that. I've read it before, long ago, but completely forgot about it. Still a great story.

Honestly, this factoid is the closest thing to a real Total Perspective Vortex that I’ve ever felt.

Thus began the Age of Fire. But soon the flames will fade and only Dark will remain.

What happens after the 10^106 years of black holes?

Also see Dyson's Eternal Intelligence:

https://en.wikipedia.org/wiki/Dyson%27s_eternal_intelligence

Basically, if you assume it's possible to upload our intelligence to a computer and run it, then you can keep the energy going to run it for a very, very long time. Well past the heat death of the rest of the universe. It depends on running things in an on and off state to conserve energy for trillions of years. Subjectively, the people in there wouldn't notice that and would simply see their active lifespans go for trillions of years. It's not clear what the limit would actually be.

It's something like Zeno's Paradox. You cut things in half each cycle, but never quite get to zero.

That's neat, stars are just the sparks after the big bang, and "soon" that energy will be gone. Even with all the bad shit happening, it makes me happy to be alive in this beautifully short window of time in the universe, even if our little dust speck circling a spark is a bit fucked up sometimes

Does thinking about the long dark make anyone else feel like they are going to vomit?

[–] IrateAnteater@sh.itjust.works 28 points 1 day ago (3 children)

The chances of me living long enough to actually be effected by it are so slim that I'm completely unconcerned about it.
