So scientists are not entirely certain about the heat death of the universe. The heat death is the most reasonable prediction given what we know but there could be a force acting across the universe that may very slowly reverse the expansion of the universe that we have yet to discover and cause a big crunch over a ridiculously large amount of time. The fact is predictions that far in the future aren't really very useful.
Does quantum foam occasionally spawn a new big bang ?
The idea of "quantum foam" occasionally spawning a new Big Bang is an intriguing concept, but it belongs more to speculative physics than established science, at least with our current understanding of cosmology.
Quantum Foam:
Quantum foam (or spacetime foam) refers to a concept derived from quantum mechanics and general relativity. It was first proposed by physicist John Wheeler in the 1950s. The basic idea is that on extremely small scales, close to the Planck length (~1.6 × 10⁻³⁵ meters), spacetime is not smooth but fluctuates wildly due to quantum uncertainty. This is because, in quantum theory, at these incredibly small scales, particles and even spacetime itself undergo constant, random fluctuations, resulting in a "foamy" structure.
Quantum Foam and Big Bangs:
The speculation that quantum foam might give rise to new universes or Big Bang-like events is tied to broader ideas in theoretical physics, including concepts like quantum cosmology, eternal inflation, and multiverse theories.
Quantum Fluctuations and Universe Creation: In some models of the universe, it is proposed that quantum fluctuations could give rise to entire universes. This is somewhat similar to how quantum fluctuations in energy can spontaneously create particles for brief moments (due to the Heisenberg uncertainty principle). Some cosmologists have extended this thinking, suggesting that a fluctuation in the quantum foam could create a new region of spacetime that expands and becomes a new universe—a new Big Bang, in essence. This is related to the idea of the multiverse, where new universes are constantly being generated through different mechanisms, including quantum fluctuations.
Eternal Inflation: Another theory that links the idea of new Big Bangs with quantum processes is the theory of eternal inflation, which proposes that our universe is just one "bubble" in a larger multiverse. In this model, the universe experiences a rapid expansion (inflation) in its early stages, and in some regions, this inflation never stops. Small regions of spacetime can "bubble off" from this eternally inflating space and form new universes with their own Big Bang events.
Cyclic or Bounce Models: There are also cyclic models of the universe (such as the ekpyrotic universe or conformal cyclic cosmology) where a universe goes through repeated cycles of expansion and contraction. In these models, the quantum foam might play a role in transitioning from one cycle to the next, though these are still speculative ideas.
Does Quantum Foam Directly Spawn Big Bangs?
Currently, the connection between quantum foam and the creation of new Big Bangs remains speculative and unproven. Our understanding of quantum gravity—the theory that would fully unify quantum mechanics and general relativity—is still incomplete. Many of the ideas related to the quantum foam, multiverses, or eternal inflation remain theoretical and lack direct empirical evidence.
While quantum foam might offer an intriguing arena for considering the birth of new universes, there is no definitive evidence that quantum foam occasionally spawns new Big Bangs, at least according to current mainstream physics.
In Summary:
Quantum foam describes the hypothetical, fluctuating nature of spacetime on extremely small scales.
Some speculative theories in physics suggest that quantum foam or related processes could, in principle, give rise to new universes (possibly via quantum fluctuations or other mechanisms).
These ideas are part of multiverse theories or eternal inflation models but remain speculative and are not established as fact.
The idea of quantum foam spawning Big Bangs is fascinating but is still in the realm of theoretical and speculative physics.
Scientific advancement, especially in quantum gravity and cosmology, might eventually give us more insights into whether such processes could occur.
If you consider particle excitement to be the definition of heat and subparticle fields to be different forms of energy then it does actually change, but that's just semantics.
If all discernable heat is unobservable and unobtainable, then semantics don't matter. Everything still dies. I'd include "heat" in that mix, but that's waxing philosophical
I imagine a physicist would invoke entropy to describe the diffusion of pressure waves and vibration into other forms of energy. Neuroscience might explain the propagation of signals from the cochlea into the brain. A psychologist could hypothesise on the influence of music on our mood and ideas. A philosopher might talk about the influence of music on the way we build our society and how that feeds back into our music. In this way, the music never stops, it continues on as echos rippling through through the universe.
Thank you and funny you should say that because Watts is an inspiration. From a scientific point of view some of his ideas were a little tenuous but as a teacher on the subject of the ineffable he was quite peerless.
So like can i get like a net and catch it?
Like its my music i paid for so like i gotta keep it for safe keeping.
Do i gotta go to another town and get it that way???
I'm not a scientist by a long shot, but my understanding is that sound if indeed a wave, carried by a medium (air, water, etc). Upon hitting your eardrum, this wave is converted by your eardrum and your auditory nerve into signals your brain decodes. The remainder of the wave continues though, until it runs out of medium, hits an obstacle (basically another medium) or dissipates. Again, just my layman's understanding!
Don’t forget the inverse square law. Even without a change in medium or any obstacles, the strength of the signal decrease over distance until it is undetectable.
This is also why there are no extraterrestrial civilizations hearing any radio broadcasts from Earth. Our transmitters are so weak that any signals we send out fade into the CMB before they get any real distance.
They've probably just got a spy satellite around earth that transmits back. Or maybe an extremely directional antenna / receiver dish would work, since they're focused on Earth specifically.
Light is also not "stuff" - it's electromagnetic radiation. It's by the unprivileged intertial frame of reference that we define the speed of light. Light's speed is the speed at which it travels unimpeded through the spacetime "field". Additionally light does not accelerate or change speed in any way while traveling in that frame.
Unless you're asking if light travels through things that are not the field known as the spacetime continuum in which case yes: light travels (and changes speed) through all sorts of materials. Like glass.
It keeps traveling. If you splash some water, where does the wave go? Same question - it terms into something you can no longer see or hear... It never goes away. It becomes part of the world, forever
Music is what you hear - but it was only ever sound waves
It stays in our brain and we subconsciously put it into new music years later, thereby keeping the industry’s corporate lawyers in cocaine for future decades to come.
After you listen to a song, the secret police from the RIAA come and lock it up in a small, dank cell given minimal sustenance, until the next time they can send it to some seedy hotel, suburban home, or automobile, to turn a trick and make them some more money, like some sort of whoo-re for the ears.
Oh, dear child, it goes to the same place where you will go when you inevitably die one day: into complete non-existence, save for an echo in others' minds, and after a while not even that.
Let's assume the kid knows it's a recording. It's still a valid question.
Like where is the recording coming from when the kid asks Alexa to play a song?
I never thought about it, as I don't have kids, but must be a bit harder explaining a global IT-infrastructure than it was for my grandpa to explaining how a VHS works. On a generalised level, that is.
All these physics answers! The funnest explanation for a kid is just that music is only there when you're listening to it. If you don't listen, there's no music. When you start listening again, music comes back. Then ask if they can hear the music of the wind.
There's a physics argument that information can't be destroyed, so in terms of causality it has an effect (see butterfly effect for reference) but because of various physical thresholds like the planck length, general limits on measurement precision (uncertainty principle, resolution limits, detection limits), chaos theory, etc, at one point it becomes indistinguishable noise.
Where do broken hearts go?
Can they find their way home
Back to the open arms
Of a love that's waiting there?
And if somebody loves you
Won't they always love you?"
Really reminded me of this - the incorrect, useless, but poetic answer could be that it's just like with love. Into the open arms of the music thats waiting there.
I can't say this did or didn't happen, but I absolutely had 'philosophical' thoughts like this as a kid.
When I was ~10 I asked my mom how we know other people aren't 'aliens or something'. She just dismissed me as being silly, and I didn't know it at the time but in retrospect I was absolutely experiencing and asking her about solipsism.
I didn't know it was 'philosophy' but I think it's integral to how we experience the world and sentience in general.
"Ultimately it increases entropy... let me tell you about the heat death of the universe..."
"No, Mom! I'm still afraid of the False Vacuum monster laying underneath my ground state!"
If those were likely to happen during our lifetime then they would have already. Now prion disease...
Good night!
Scare me with prion disease?

I read a SciFi book where there was a group in the world that does general science in the name of averting the heat death of the universe.
Ah yes, the ol' "If a tree falls in the woods does it make a sound?" approach to preventing the death of the universe.
I don't quite understand. Care to elaborate?
Existence is in the eye of the beholder. For something to exist it must be observed.
It sounds like in the book you read performing general science would go towards observing the universe preventing its heat death?
I dunno if fully applicable, but that's what I got out of it :D

Yes, this answer, the kid fucked around (asked questions), now it's time to find out.
Heat. Everything ends up as heat.
Until the day that even heat dies.
Well, heat just spread over a larger area but it doesn't get destroyer nor turn into any other form of energy.
But it doesn't die per se.
If you consider particle excitement to be the definition of heat and subparticle fields to be different forms of energy then it does actually change, but that's just semantics.
If all discernable heat is unobservable and unobtainable, then semantics don't matter. Everything still dies. I'd include "heat" in that mix, but that's waxing philosophical
Well not all sound.
But yes 99.99%
So where do smells go?
Just open a window. I'm sure they noticed, but they'll be cool about it.
they get trapped in your nose hairs, this is why old people have really stinky noses.
Really? How can you smell?
well i'm not very old yet so i can smell many different ways depending on how recently i showered and whether i put on perfume
;) nah I was being doofily punny, like “how could you tell?”
I imagine a physicist would invoke entropy to describe the diffusion of pressure waves and vibration into other forms of energy. Neuroscience might explain the propagation of signals from the cochlea into the brain. A psychologist could hypothesise on the influence of music on our mood and ideas. A philosopher might talk about the influence of music on the way we build our society and how that feeds back into our music. In this way, the music never stops, it continues on as echos rippling through through the universe.
I think this is my favorite comment I've read on Lemmy so far.
We didn’t start the music, it was always playing since the world was turning
Beautiful. We are just one of many instruments that express the music.
That gave me some real Alan Watts vibes. If this came from your own brain, be proud of this comment. Beautifully worded and inspiring.
Thank you and funny you should say that because Watts is an inspiration. From a scientific point of view some of his ideas were a little tenuous but as a teacher on the subject of the ineffable he was quite peerless.
You absorb it into your soul and it changes you irreversibly forever.
As the waves from ocean, the music crashes on the beaches in your ears
Like sand through your beer glass, these are the waves of our lives
And slowly erodes it.
What?
Everyone knows this duh!
Into your heart!
Groove is stored in the heart
Where does the light go when you flip the switch?
Check your fridge.
"Hello, light!" https://youtu.be/nm1_bKFhYIY
Hello lightness my new friend
It rolls up into the other side of the cassette. Just flip it over.
I thought the sentence was going to lead to something like "It rolls up into the other 8 inaccessibly tiny dimensions of our space."
I love your oldschool explanation though!
It turns out the solution to quantum string theory is a double-sided tape.
Sounds move very very fast, faster than a runner or a car, so it goes very very far away.
Very good ELI5.
Now do a "Calvin's Dad" explanation.
It dissolves, that's where dust comes from.
When eli2000BCE? Coming out
Tho needith explanation to the highest degree, in between pilliaging villages and plauge season
Emphasis on the 5, tho.
Like, to the next town over, or even further?
Only way to find out is to get there faster.
So like can i get like a net and catch it? Like its my music i paid for so like i gotta keep it for safe keeping. Do i gotta go to another town and get it that way???
Lmao im joking Good explanation tho
But gets slower and more tired as he runs, until he dies?
It gets stuck in my head for 3 to 4 days until something newer comes along and pushes it out.
I'm not a scientist by a long shot, but my understanding is that sound if indeed a wave, carried by a medium (air, water, etc). Upon hitting your eardrum, this wave is converted by your eardrum and your auditory nerve into signals your brain decodes.

This is also why there are no extraterrestrial civilizations hearing any radio broadcasts from Earth. Our transmitters are so weak that any signals we send out fade into the CMB before they get any real distance.
So Lrrr and Ndnd warching Single Female Lawyer 1000 years in the future is a lie?
They would not have been able to watch it from an original OTA broadcast, no.
Unless they have an extensive network of wormhole repeateds
They've probably just got a spy satellite around earth that transmits back. Or maybe an extremely directional antenna / receiver dish would work, since they're focused on Earth specifically.
You area conflating auditory waves with radio waves.
These are very much not the same thing. Sound waves require a medium while radio waves do not.
Radio waves travel vast distances through space while sound doesn't travel at all.
Space is a medium, as exemplified by the fact that light curves around massive objects, because the space is curved.
Space isn't a medium because mediums have privileged frames of reference.
You're talking about spacetime which is a field, not a medium.
So you’re saying that light can travel through not-space?
Light is also not "stuff" - it's electromagnetic radiation. It's by the unprivileged intertial frame of reference that we define the speed of light. Light's speed is the speed at which it travels unimpeded through the spacetime "field". Additionally light does not accelerate or change speed in any way while traveling in that frame.
Unless you're asking if light travels through things that are not the field known as the spacetime continuum in which case yes: light travels (and changes speed) through all sorts of materials. Like glass.
Don't materials also need to exist in space?
If they didn't fade with distance, So for now we are still quiet in the dark forest.
If we had FTL I'd be a radio archaeologist, flying out to various distances to attempt to capture lost episodes of old TV shows like Doctor Who
False, it gets stuck in my head, to be played over and over until the next song gets stuck in my head.
A little bit reflexts off your eardrumm too!
It goes into your memory. That's why you can remember a song that you heard before.
That’s why music works at all.
The Langoliers eat it.
It keeps traveling. If you splash some water, where does the wave go? Same question - it terms into something you can no longer see or hear... It never goes away. It becomes part of the world, forever
Music is what you hear - but it was only ever sound waves
It stays in our brain and we subconsciously put it into new music years later, thereby keeping the industry’s corporate lawyers in cocaine for future decades to come.
I was into neural net plagiarism before it was cool!
The best and the worst go straight to your brain and live there rent free.
Unfortunately, nobody has figured out how toget rid of the bad songs that drown out the good ones.
The Langoliers eat it
Some of that sound rearranges some of your neurons so that you can listen to Never Gonna Give You Up whenever you read this
After you listen to a song, the secret police from the RIAA come and lock it up in a small, dank cell given minimal sustenance, until the next time they can send it to some seedy hotel, suburban home, or automobile, to turn a trick and make them some more money, like some sort of whoo-re for the ears.
Oh, dear child, it goes to the same place where you will go when you inevitably die one day: into complete non-existence, save for an echo in others' minds, and after a while not even that.
Sweet dreams!
You just reminded me of: https://sh.itjust.works/post/26469474
Warning: may cause big sad
In your ears
Tell him about the day that music died
Great song 👌👌👌
It turns into memories and heat.
the music goes back again to be later re streamed to other people that might need it
Into darkness, my old friend.
I've come to talk with you again.
Because a vision softly creeping
Left its seeds while I was sleeping
And the vision that was planted in my brain Still remains
Within the sound of silence
It dissipates into the air like butterflies, or a cloud of dust.
It's still there, it's just in the past now.
Let's assume the kid knows it's a recording. It's still a valid question.
Like where is the recording coming from when the kid asks Alexa to play a song?
I never thought about it, as I don't have kids, but must be a bit harder explaining a global IT-infrastructure than it was for my grandpa to explaining how a VHS works. On a generalised level, that is.
The kid made a mistake asking where music came from. Now me must learn about TCP/IP, NTP and DNS 💀💀💀💀
The kid is gonna need naptime and to clear the next 3 years of his schedule. This is gonna get complicated.....
Wowh woah you gotta start with the basics!
...OSI model.
it's sitting on the computer waiting to play again
"how is it now playing here in the car if it's on the computer at home...?"
edit also "a computer at home" feels fairly outdated, when even very young kids have smartphones
"Everywhere, all at once. That's why if you put your ear close to speakers it might collect too much and that can hurt your ear"
"Where do you think it goes?"
we hang it on a wall of silence in the room of our imagination
All these physics answers! The funnest explanation for a kid is just that music is only there when you're listening to it. If you don't listen, there's no music. When you start listening again, music comes back. Then ask if they can hear the music of the wind.
Can you hear the music of dad's bowl movements?
Ha! Gotta rip one as they're listening to the wind in the trees.
The music stays in your head until your forget it. Music only exists in your head
It stays playing in my head on repeat until a different piece of music replaces it.
I can attest, this is playing in my head right now
https://www.youtube.com/watch?v=iR-K2rUP86M
To retire on a farm upstate, unless my mom lied to me 🤔
It goes on until it doesn’t? Seems like there’s a pseudo-scientific philosophical argument that it continues on forever at some quantum level?
There's a physics argument that information can't be destroyed, so in terms of causality it has an effect (see butterfly effect for reference) but because of various physical thresholds like the planck length, general limits on measurement precision (uncertainty principle, resolution limits, detection limits), chaos theory, etc, at one point it becomes indistinguishable noise.
It goes out into the world, to be merged alongside all of the other sounds, until it can be recycled as "new" music and you can enjoy it again:-).
into our minds and into our hearts
They should show their kid this.
That should be required viewing. For everyone.
(Okay the water coming out the hose was freaky.)
It diverges into the quantum realm of misheard lyrics.
The music stays there we keep moving
Nothing's really ever gone
But actually though, music goes up into the sky and becomes clouds.
oh when will they ever learn? oh when will they... ever learn
syncs brain cells for later
As someone with a degree in Philosophy, I don't think this is really a philosophical question. The science is interesting and useful to know
If we can try with every day
To make it better as it goes
With any luck then I suppose
The music never ends
My guess is the music goes into the past, leaving echos in your memories.
It goes into the ears.
Music is stored in the ears
"And can you please tell me, oh
Where do broken hearts go?
Can they find their way home
Back to the open arms
Of a love that's waiting there?
And if somebody loves you
Won't they always love you?"
Really reminded me of this - the incorrect, useless, but poetic answer could be that it's just like with love. Into the open arms of the music thats waiting there.
Tell the truth in simple. I was annoyed to learn that there aren't any crawlies that go back up your throath if you swallow toothpaste.
Why would that be annoying instead of relieving?
It goes straight up my ass!
that happened
Completely real story
Kids ask weird things
What was that subreddit for parents who made up shit about what their kids obviously didn't say?
This goes there.
What was the subreddit that makes fun of people who never believe that kids ever say anything bizarre or ask unusual questions?
Your comment belongs there.
This is just another variant of "after we turn the lights off, where does the light go?"
This obviously r/thathappened bait.
I can't say this did or didn't happen, but I absolutely had 'philosophical' thoughts like this as a kid.
When I was ~10 I asked my mom how we know other people aren't 'aliens or something'. She just dismissed me as being silly, and I didn't know it at the time but in retrospect I was absolutely experiencing and asking her about solipsism.
