Does anyone ever get depressed at the thought that the universe

No. Entropy is the reality and normality. Thinking anything can last forever is the mistake.

I think it's incredibly arrogant of you that you that you think something that will happen billions of years from now concerns you in the slightest.

>>8427508

Yeah you don't know what this word means. Being worried that all of existence will end doesn't translate to being all about yourself.

The whole "you are arrogant to think of the afterlife/entropy/death/eternity" is a bullshut fedora argument said by nihilists trying to pretend they arent having an existential crisis

Humans will eventually become so technologically advanced that we will be able to stop and reverse entropy. Or well just leave this dimension and colonize another one

Not sure why it has to end.

I understand the theory, that everything is essentially slowly flying apart. There is no reason to believe that humans won't eventually reach the point of technology where we can build everything we need, artificial suns, dyson sphere type habitats, etc such that even if the rest of the universe and its natural galaxies and systems all dissipated into nothingness we could still live on in our artificial worlds.

Not sure what your getting at. My point was more, if all the trees died out we would just make artificial tree like things to replace them. In that case perhaps an umbrella would do?

>>8427744
You'd have trouble digesting it if entropy is reversed.

>>8427522
All that could possibly be worrisome about the universe ending, eons after you and the rest of the human race is dead and dust, is the death of your legacy. Which is pretty fucking arrogant.

Good work anon, gotta snap those tall poppies.

>>8427862
It's a quote from The Last Question by Isaac Asimov, a short story about the heat death of the universe. You see, we may be able to construct an artificial star, but to do that, we need hydrogen and other light elements, and we only have so much of those. Even if we totally annihilated matter to get all the juice out of it, we could only go on so long as we have matter to burn. And we can't just reuse the energy, because we would be radiating part of it away into space, so no matter how efficient we are, we will eventually run out of fuel.

There are other concerning things that will end us soon before that tho, read the Wikipedia article titled timeline of the far future if you're interested.

I do find the thought of it terrifying. Even if we escape the death of our own Sun, we'll still run out of stars eventually. Even if we make our own fusion generators, we'll still run out of hydrogen eventually.

Just imagine the terror and dread of anything that survives that long. Whatever sentience remains, it will spend it's days drifting through the blackness, trying to suck the power out of slight differences in background radiation, lapping energy from cooling husks of neutron star and evaporating black holes. Trillions of years worth of experience and knowledge, gradually losing the ability to think due to all of it's ability being focused on the smaller and smaller differences in energy it can extract from the environment, until one day, in the blackest void imaginable, completely alone, it finally runs of out juice and ceases to live.

>>8427907
True, but we should theoretically be able to harvest or convert all energy and matter at some point in the future. Thus if it happens soon enough we could stop the end from coming.

Humans won't be around, consciousness will be just fine, here's why:

We can build kugleblitz black holes that are small enough to emit hawking radiation faster than the background radiation temp. We can drop the most enthropic matter into them and get hydrogen precursors out. (obviously you would need lots of them with channels to collect and whik away the new matter).

Ok, now the intelligence has to worry about universal expansion. Yes, intelligences could leapfrog their hardware down to plank scales (assuming they found a way to deal with the quantum uncertainty of hardware on those scales) but they could not prevent the eventual shrinking of the visible universe down to the plank length. They could stave it off for a while by making time pass much slower for them (because they can speed up their clockrate to plank time), but eventually the shrinking visible universe sphere will make each plank cube unable to exchange data with its' neighbors. At that point the standard universe occupants as are familiar to us today are screwed. They won't care though, self preservation is a human manifest, and although the entities will be able to experience several times the full compliment of human emotions, they will intelligently be at peace with the fact that the story has been well told.

>>8428784
In the reading, he claims everything got close to abs 0... that's not entropy? the exact Kelvin degree of perfect entropy with the energy and within all the volume we have now could probably be calculated. If an infrared photon leaves a hunk of material, it will be immediately replaced by another when there is perfect entropy

>>8428909
>the eventual shrinking of the visible universe down to the plank length.
what? haven't heard of this one before

>>8428041
The process wastes energy always.
You run out eventually

>>8429298
Yeah, it will shrink increasingly, the only reason I included the plank length is because that is the smallest known possible scale to refuge an intelligence on as the visible universe shrinks. It will of course first shrink to solar system size, planet size, city size, etc.

This universal penile atrophy is due to the increasing, symmetrical, rate of expansion of the entire universe, Right now we can't see beyond a 36 billion light-year distance (13 billion year time) away from us. This is because everything beyond this distance is effectively moving away from us faster than light due to spacetime expansion between us and those objects. Eventually things at a billion light-year distance will be moving away from us faster than light, followed by things at a single light-year distance, etc.

If you were watching it happen you would witness the stars start to disappear as the darkness began consuming. The darkness would grow closer and closer as you saw the solar system being consumed from the outside in, the sun would be consumed and by the faint glow of some earth cities you could still make out the moon disappearing, then you could watch as the planet was consumed from the horizons in, and you would be weightless just before your bedroom walls faded to black right before your eyes.

The sphere of visibility is diminishing now, but very slowly. By the time the spacetime within distances of your own body gets close to expanding at the critical rate, it will happen quickly, probably within a few minutes of you seeing the last star go dark. It will be like getting sucked under a wave, claustrophobia at its finest.

>>8429405
Oh so you're talking about the "big rip".
>penile atrophy
what? are you trolling?

>>8429423
Not trolling, just wanted a catchy term for shrinkage. What's the big rip?

>>8429428
>The Big Rip is a cosmological hypothesis about the ultimate fate of the universe, in which the matter of the universe, from stars and galaxies to atoms and subatomic particles, and even spacetime itself, is progressively torn apart by the expansion of the universe at a certain time in the future. According to the hypothesis, first published in 2003, the scale factor of the universe and with it all distances in the universe will become infinite at a finite time in the future.

In that case yes, I was talking about the rip. I don't see how space-time could rip itself apart though, it seems like it should just keep growing.

the universe has to end someday....
Proof please?
Currently the universe is endless and timeless, theories about a start and an end are just that, projections from a human mind obsessed with the birth/death enigma.

>>8427907
Came here to recommend this reading to OP and others like him.

Also, no. The heat death does not concern me anymore than flipping a coin or rolling dice concerns me. It's not malicious or personal. Why should it bother me? It's simply just a matter of statistics and how they play out on a cosmic scale.

>>8428041
>>8427907
Asimov wrote this tall tale before we realized the universe's expansion is accelerating... Which does rather complicate things. I think he has a multi-galaxy civilization going in the later stages of the story, but all the non-blue shifted galaxies will be beyond our sight well before the last of the stars burns down (taking into account those new stars that are created meantime).

Part of the problem is that only a tiny fraction of stars go nova. The bulk of the rest never return their matter to the universe - especially true of the black holes... Which, I suppose, eventually do, but not before well after everything else is dark. ...And even when they do, their energy will be instantly lost to a hyper-accelerated expansion of the universe.

But, given how far into the fantastically distant future we're talking, we may find a solution. We already know it's theoretically possible to create another universe with a large enough particle accelerator (like, solar system sized), there's just, currently no theoretically way to get from this universe to the one you made. Still... Seems there are some other potentials for cat skinning here.

>>8429457
Theories generated from and backed by observation. The same theories which many of our devices depend on to function. The fact that your phone's GPS works is proof that some of the major theories behind those is correct (or at least well within the ball park.)

I rather like Asimov's answer in The Gods Themselves where we start opening doors into other universes and simply start sucking energy from them.

You guys realize all this "matter can't be created or destroyed" and "there will be nowhere to run" shit is bullshit right? What we really mean is that it can't be done under normal circumstances, obviously it can be done, you're looking at it right now. It had to get here somehow so obviously it's possible, we just don't know how. We're studying shit like quantum tunneling right now, imagine what humans in a billion years will know. I doubt we'll get anywhere near heat death before we gain the ability to do something about it

>>8429707
So we create White Holes in a certain spot in the universe and just siphon energy from them?

You made me think that maybe we could avoid the big rip by diving into a black hole. Some very large black holes don't rip you apart because they are so un-dense. Since spacetime is already warped into a singularity there, maybe falling at the exact right rate could curtail the ever-expansion problem.

>>8430186
Already more or less proposed by >>8428909 - bugger is, black holes evaporate, so you're just buying yourself time.

...Granted, several trillion years more time... But once you're living inside an event horizon, fixing the problem permanently might be more difficult. (On the other hand, if you've found a way to do that, you probably already have a solution, and thus wouldn't do that.)
