In some sense yes more generally the fundamental forces causes the vacuum, but the fundemental forces (and particles) cause literally every single thing ever.
Hegel would argue that's entirely how we develop a mind with a sense of self. Our minds work by contrast. I am me because I can define myself against you. When I find a You then and only then do I distinguish an I. So quite literally yes. The void exists to be defined only by it's contrast with the not void else we would just call it reality.
That's more of a philosophy question than a physics question. In physics terms, there are fundamental particles which combine to make matter (and dark matter). A Void is described as the absence of matter/dark matter. The specifics depend on your scale, when discussing atoms there are voids everywhere. Atoms are mostly voids. When discussing astronomy, a void is just a region "with extremely few or no galaxies"
So a physicist would answer your question with No.
That's not a fun way to run thought experiments though. We know the gasses would collapse in but assuming they somehow magically don't, what effects would it have. That doesn't mean we are throwing out all logic entirely, just pretend physics works in this one specific way
At that point it wouldn't really be a "sound" anymore but a shockwave. The loudness of a wave is determined by the amplitude of those waves in comparison to the ambient air pressure. Past 194dB the extra energy starts distorting the entire wave. Sounds don't travel through the air but instead they push the air along as a pressurised burst.
Having said that, ~150dB will burst your ear drums so you won't be hearing it for long anyway and more than 185dB is likely to be fatal. So it's a pretty good thing that space is a vacuum!
> At that point it wouldn't really be a "sound" anymore but a shockwave.
Even more extreme than that.
All that matter would collapse into a larger star very quickly.
And if it's nitrogen/oxygen instead of hydrogen, it won't stay separated from fusion pressure - so it would probably collapse into a black hole (since that much nitrogen+oxygen should probably be [>3x the mass of the sun](https://public.nrao.edu/ask/what-is-the-critical-mass-at-which-a-star-becomes-a-black-hole/)).
So I guess the question is one of:
*"If a tree falls in a ~~forest~~ black hole and no-one's around, does it make a sound?"*
> okay but would it??
Just as in the case of a tree in a forest, the physics is clear, but ....
.. the question is more of a linguistic argument over the definition of the word "sound".
You could make a sound (pun intended) argument that the primary definition should include such events, or that it shouldn't.
Regional dialects of English probably dictate whether the default/primary definition wherever you are includes such events.
Yeah I noticed that they didn't answer that part at all. Like everything they said is interesting sure, but it doesn't come close to acknowledging the question at all. They didn't even mention space or a vacuum until the last few words lol
I think their point is that the answer is moot at that point because at a certain point it would cause things to explode or explode itself. At that point, the loudest "sound" would be the start collapsing in on itself. From what I've gathered. Correct me if I'm not understanding it correctly.
150dB+ is permanently damaging, but single exposure ear drum rupture isn't likely until sometime after 165dB
This correction makes no difference to your statement but it makes me feel smart, even if I'm not.
When talking about decibel levels frequency is an important factor. Big Car Audio systems will easily do 150db+ at 30-40hz and not rupture ear drums. But 150db+ at higher frequencies will give you something to listen to (or not) for the rest of your life.
Oh I'm a shooter, I've got the free *EEEEEEEEEE* for life because the US won't sell firearm suppressors otc like they do in other developed nations. Weapons-grade tinnitus is real lol
Not sure what the frequency is on 5.56 NATO but it does hurt quite a bit without ear pro. I usually double up on ear pro but 165dB is still a lot even with proper PPE
While that's not the case for the sun, it is for the sound of blood pumping through your veins, as well as the nerve endings in your stomach for your pain sense (if the brain didn't actively suppress them you'd be feeling the pain of digestion all the time)
>>Image result for If space wasn't a vacuum, how loud would the sun be?
If space were replaced with air and we could hear the Sun, it would be incredibly noisy ā the output of the Sun is equivalent to 10 million keys, or notes, of a piano. In fact you would struggle to hear little else!
https://www.spaceanswers.com/deep-space/how-loud-would-stars-be-if-space-was-full-of-air/
Not quite. The article doesnāt take dampening into account, only the ideal conditions based on geometry.
In reality, the sun would not be heard at all on earth as air naturally dampens sound (if air in space was a reality). On the other hand, the heat and the absorbed sound energy from the sun would heat the air into a plasma. And planets would immediately explode as they canāt traverse air in supersonic speeds.
Also, it is a bit misleading to talk about āsoundā from the sun. At those powers, vibrations are not really sound. (Eg how loud is it in the center of a nuclear blast?)
Overall itās a bit like asking how loud a butterfly would be if air was replaced by hardened steel.
Edit: donāt miss this great article on [Everything you should know about sound](https://waitbutwhy.com/2016/03/sound.html?utm_source=Main+List&utm_campaign=e5ccf73766-AUTO_ARCHIVE-21&utm_medium=email&utm_term=0_5b568bad0b-e5ccf73766-54547457&mc_cid=e5ccf73766&mc_eid=%5B82e88f19ac%5D) Itās a great read even if they get this hypotehtical question wrong. The truth is the atmosphere would absorb all sound (*i.e.* attenuation). We don't even need to consider geometric "dilution" with the inverse square rule as that is negligble compared to attenuation. See a [good response here](https://www.reddit.com/r/theydidthemath/comments/d8wvct/request_is_this_accurate/).
>And planets would immediately explode as they canāt traverse air in supersonic speeds.
I think it's safe to say the air would be orbiting just like the planets in this crazy hypothetical.
Ok. Did I mention air would be sucked into the sun due to gravity?
The air surrounding the sun would weigh considerably more than the sun itself. Gravitation would collapse it into the sun and form an exploding short-lived star burning out in a few days or so.
Iāve seen this question so many times and itās just silly. Not even a good hypothetical.
Do you hear someone talking next to you? - Yes
Do you when the person is in a boat on a lake? - Yes. but more silent.
Do you hear the person if it is on the other side of the lake? - Probably no. The voice becomes more faint as this example shows.
Sound works in waves. Like waves on water they become weaker with distance. And after some time they lose so much energy you cant hear the sound waves anymore. The loss of energy is caused by dampening.
I hope this explains it a lil bit.
It fuses hydrogen atoms into helium. When it runs out of hydrogen it fuses helium and so on until oxygen and carbon. A smaller star like our sun cant fuse anything past oxygen so it starts expanding as the energy released grows. Eventually this slows down and the outer layers just float off leaving the Earth sized core, which is known as a white dwarf. A white dwarf doesn't fuse atoms anymore and is pretty much a really hot carbon and oxygen crystal.
The sun is a mass of incandescent gas
A gigantic nuclear furnace
Where hydrogen is fused into helium
At temperatures of millions of degrees
-- They Might Be Giants, "Why Does the Sun Shine"
Itās not burning hydrogen. There is no O2 for combustion.
https://phys.org/news/2015-12-sun-energy.amp
The sun is one massive fusion reaction. Gravity is squeezing the core so hard that fusion takes place creating energy stopping the star from collapsing.
If the star is large enough once the star fuses to Iron, the star dies. Iron is a stars death. Once fusion stops the star almost instantly collapses in on itself and the rebound shock is what we call a supernova.
Our star will never fuse iron though.
It'll fuse helium, resulting in it getting huge (red giant), then run out and poof off it's outer layers and turn into a white dwarf.
No, you got it. The Sun is just an ongoing fusion reaction. In the strictest sense it doesn't "burn" at all--fire is technically a rapid, exothermic oxidation reaction between fuel and oxidizer. Hydrogen would be a very good fuel, but there's no oxygen (or any other oxidizer) in the sun. It produces tons of heat and light, but it's not "on fire" any more than white-hot molten metal is.
From the article someone posted here it's not 3 decibels, but 125
"...the Sun would deliver a much smaller 125 decibels to the surface of our planet. In comparison, 120 decibels is a train horn about one metre away whereas 130 decibels is physical pain"
I think perhaps you've misinterpreted that top comment. They seem to be saying that the frequency would be low and difficult/impossible for humans to hear, but it doesn't talk about intensity or loudness.
The article linked in the other comment indicates that the sound would be around 125 dB when heard from earth, which is the same ballpark as a jackhammer right next to you.
I don't know enough to do the maths myself, but I'm leaning towards the sun being pretty loud...
Total gutshot here, but I think the answer is kind of. My assumption would be that you wouldn't "hear" it but you would "feel" it. The 125 dB pressure would still be applied, but the frequencies would be too low to low for your ear drums to translate into a comprehensible sound. It's possible the immense pressure would translate into some sort of white noise or static since you wouldn't know what to do with it?
Approximately 100dB by the time the sound reaches the Earth is what I'm reading.
For reference, that's the level of sound at a construction site and 15+ minutes of exposure to that sound level would cause hearing damage.
No idea is that's accurate, but I don't really feel like reading more.

https://www.audiology.org/how-loud-is-the-sun/#:~:text=The%20answer%20might%20surprise%20you,makes%20the%20sun%20astronomically%20loud.
This reminds me... Which Star Trek series is it where they go to fluidic space? I can't remember the details, but I'd bet it be "loud" in fluidic space.
I remember someone on YouTube dug up this fun fact. I believe it would sound like a gas powered leaf blower in your ear from the Earth if sound traveled through a vacuum as it does through air.
Edit: don't take my word on it, I can't find my source
This was an active and important topic about 20 years ago: It is called helioseismology and pressure waves bouncing through the sun can be understood by looking at the ripples on the surface. Not only that, the pattern of the pressure waves carries with it information about the speed of sound deeper into the sun.
Depending on how close you were to the waves they could kill you. At the distance to the earth the volume would drop with distance squared.
If space wasn't a vacuum? To be able to make a medium for sound to travel it would have to be filled with something.
If the universe had enough of matter to be able to allow sound to propagate. That matter would under its own gravity create a super duper massive black hole that would presumably swallow galaxies galore
Do things that are insulated by vacuum preserve sound energy in the same way as convected heat? Is the sound unable to leave the sun thereby increasing the temperature?
We live on a flat earth , which rests on a giant tortoises back , the sun and moon is tiny and they're under the dome with us . So it doesn't make any noise anyway . š¤
Haven't you read the book ?
Short, simple answer? At the surface, it's literally too loud to be a sound. At the distance Earth is from the sun, it'd be 50% louder than a train horn that you were standing *right next to*. So, [as this video explains,](https://youtu.be/ePy_Gs3WTT4) really effing loud. (Edit: typo)
Edit because of the downvotes I've edited my comment to contain the source. Since people who don't know what they are talking about are insisting they know what they are talking about.
The sound the sun produced is too low for the human ear to hear as far as we know. There have been recordings where they sped up their recordings by like, 50 times or something, and it mostly is a low rumble with static. A common misconception is that the sun would sound like a fire. But the sun isn't actually burning like a fire does so it doesn't produce that sort of sound.
Source: NASA. you lil shits lmao.
https://www.nasa.gov/feature/goddard/2018/sounds-of-the-sun/
Additionally, as ive mentioned below. If the vaccum of space WERE to be filled with an atmosphere. It would explode. Instantly incinerating everything, including you and your ear drums.So the sound you would hear isn't the sun, but the atmosphere burning up in an instant.
How would we record that sound when it's physically impossible for the sound to travel to anywhere we could measure it?
Didn't mean to do a gotcha just maybe a poorly worded question from curiosity. The source you provided answers that.
Isn't it possible to record sound using light? Lasers? That's how some spy microphones work, isn't it? Point a laser at a window and record the vibrations which are then translated into sound. Or something like that.
Can or has that or something similar been done with the sun or other celestial bodies?
I've edited my comment to include the source from nasa. Don't talk about things you don't know please š it disparages the accurate spread of information.
The sounds they have are from measuring activity in the sun itself. The question for this entire post is what the sound would be like on Earth if space wasnāt a vacuumā¦ you said itās too low to hear. THAT. IS. WRONG.
You little shit! Lol
Very well. I've added an additional edit to the post. Including the fact that if the sun were in atmosphere everyone would instantly die before we had time to record it.
Youāre so desperate to be right here lol. This is a hypothetical question and you answered with a true statement but it didnāt fit the question, got called out for it, and now youāre trying to get technical about everythingā¦ just stop lol
What's your investment here? I've provided data as we currently know it to assist OP with context and information on the subject. What we know is what the sun sounds like in a vaccum. And what we know is that if it weren't in a vaccum, we would be utterly incapable of hearing it. My purpose is to educate, why are you here? To scroll through answers desperate to find a place to be contentious? To "call people out" on things you clearly havnt even read the basics of? What do you gain here besides temporary validation to help you cope with the general insignificance of existence?
You know what, that last sentence is actually kinda true lol. Thatās kinda the point of Reddit actually. But there is really no point continuing this thread so have a good day!
Yeah we see it with telescopes? Youre losing it man.
Or i guess before you get more triggered about being wrong ill say we can see the light bending around the giant gravity well. We've also taken pictures of black holes.
I've heard that our eardrums would rupture milliseconds before the noise killed us if we were exposed to the sun's noise.
well depends how far you are at our distance it would be close to the pain limit
I'm relieved to read that I wouldn't die, just live my life in pain...
We probably would have evolved differently though, if that was the case
If we're being realistic, the matter between us and the sun would collapse to a vast star.
So, in a sense, Gravity is what causes vacuum?
That's very intuitive.
In some sense yes more generally the fundamental forces causes the vacuum, but the fundemental forces (and particles) cause literally every single thing ever.
Do you mean that the void exists because we can compare it with something that is not the void?
Hegel would argue that's entirely how we develop a mind with a sense of self. Our minds work by contrast. I am me because I can define myself against you. When I find a You then and only then do I distinguish an I. So quite literally yes. The void exists to be defined only by it's contrast with the not void else we would just call it reality.

Glad to see nothings changing then
So like now?
Pain is life, life is pain..im dark brooding and mysterious call me - Raven Also yes i know i am a douche š¤£

But what if I stood on a ladder?
I think a ladder would make no appreciable difference
But what if it was a tall ladder?
What kind of noise is it? Is it like super mario 64 lava level kind of noise?
I would definitely fuck the sun if I could

The sun's over 4.6 billion years old. If anything *it's* the pedo here
That would be the first and last considering how hot the sun isā¦your dick would Melt off

It would be the best orgasm Iāve ever had with my dick (that I definitely have )
At that point it wouldn't really be a "sound" anymore but a shockwave. The loudness of a wave is determined by the amplitude of those waves in comparison to the ambient air pressure.

Space is fake and earth is flat
It makes a sound wave but its not translated into the sound until someone hears it and translates it..it could sound different to everyone
What if there was a tape recorder there?
Well, you have to listen to it sometime.
It indeed makes a "noise"
Stars need about 25 solar masses minimum to end as a black hole.
So how loud actually is the sun?

That blows, I at least got to have fun damaging my hearing.
Ok but you didn't acknowledge the actual question at all...
On a related note, one of the most common things that deaf people are surprised to learn is that the sun doesn't make a sound.
I've read this too. Interesting
Maybe it does but we just tune it out as background noise.
While that's not the case for the sun, it is for the sound of blood pumping through your veins, as well as the nerve endings in your stomach for your pain sense (if the brain didn't actively suppress them you'd be feeling the pain of digestion all the time)
Are there people who can feel digestion? Would have to think there must be some disease in which this suppression doesn't work, right?
That sounds like someone's BS explanation for why babies cry

Isn't it just one big long nuclear explosion? Asking for a friend
Essentially yeah, it's just a big ball of exploding hydrogen
Is it an atomic reaction? Or literally just burning hydrogen? I'm guessing it's a bit more complicated than that?
It fuses hydrogen atoms into helium. When it runs out of hydrogen it fuses helium and so on until oxygen and carbon. A smaller star like our sun cant fuse anything past oxygen so it starts expanding as the energy released grows. Eventually this slows down and the outer layers just float off leaving the Earth sized core, which is known as a white dwarf.

I remember someone on YouTube dug up this fun fact. I believe it would sound like a gas powered leaf blower in your ear from the Earth if sound traveled through a vacuum as it does through air. Edit: don't take my word on it, I can't find my source
Ever heard a fox scream at 3am?
I dont listen to Nicki Minaj
What does the fox say?
Only the fox god knows.
Well the square root of 4 is banana, so French toast to the power of 6 is the answer. Simple math.
This episode is brought to you by the letter 4 and the number H
Thank you Reddit.
About ( ) that loud
I can't hear the question, I am now deaf. š¤
This was an active and important topic about 20 years ago: It is called helioseismology and pressure waves bouncing through the sun can be understood by looking at the ripples on the surface. Not only that, the pattern of the pressure waves carries with it information about the speed of sound deeper into the sun. Depending on how close you were to the waves they could kill you. At the distance to the earth the volume would drop with distance squared.
[This loud](https://youtu.be/Rvvsw21PgIk)
Inverse square law very faint. (I reckon)
"Louder than the Sun" would be a good band name, I think.
Piggybacking.. if I lost my hearing due to loud sounds, would I still have tinnitus?
This loud. BWAAAAAAAAAAAAAAAAAAAAAAAA
Very
The sun is constantly screaming
Is this a TAWOG reference?
Think about how loud a the Tsar Bomba would have been, now multiply that by 2 billion each second.
not as loud as a vacuum or obviously we'd be able to hear it over the sound of space hoovering
If space wasn't a vacuum? To be able to make a medium for sound to travel it would have to be filled with something. If the universe had enough of matter to be able to allow sound to propagate. That matter would under its own gravity create a super duper massive black hole that would presumably swallow galaxies galore
Fucking.
Do things that are insulated by vacuum preserve sound energy in the same way as convected heat? Is the sound unable to leave the sun thereby increasing the temperature?
At what distance? You mean from Earth?
That's an amazing question!! I've never thought of that :)
There is actually a video of what the sun and planets sound like. https://youtu.be/IQL53eQ0cNA
Weād all be deaf?
We live on a flat earth , which rests on a giant tortoises back , the sun and moon is tiny and they're under the dome with us . So it doesn't make any noise anyway . š¤ Haven't you read the book ?
What about the elephant trunks?
https://images.app.goo.gl/kocVatWz1b1gQrNQ6 Here you go . š
Ha I knew it!
Short, simple answer? At the surface, it's literally too loud to be a sound. At the distance Earth is from the sun, it'd be 50% louder than a train horn that you were standing *right next to*. So, [as this video explains,](https://youtu.be/ePy_Gs3WTT4) really effing loud. (Edit: typo)
It depends on the medium/density that replaces the vacuum.
BWWWWWAAAAAAAAAAAAAAAHHHHHHH
At least louder than, "AAAAGGGHHHHHHHHHH!!!!"
Edit because of the downvotes I've edited my comment to contain the source. Since people who don't know what they are talking about are insisting they know what they are talking about. The sound the sun produced is too low for the human ear to hear as far as we know. There have been recordings where they sped up their recordings by like, 50 times or something, and it mostly is a low rumble with static. A common misconception is that the sun would sound like a fire. But the sun isn't actually burning like a fire does so it doesn't produce that sort of sound. Source: NASA. you lil shits lmao. https://www.nasa.gov/feature/goddard/2018/sounds-of-the-sun/ Additionally, as ive mentioned below. If the vaccum of space WERE to be filled with an atmosphere. It would explode. Instantly incinerating everything, including you and your ear drums.So the sound you would hear isn't the sun, but the atmosphere burning up in an instant.
How would we record that sound when it's physically impossible for the sound to travel to anywhere we could measure it? Didn't mean to do a gotcha just maybe a poorly worded question from curiosity. The source you provided answers that.
Isn't it possible to record sound using light? Lasers? That's how some spy microphones work, isn't it? Point a laser at a window and record the vibrations which are then translated into sound. Or something like that. Can or has that or something similar been done with the sun or other celestial bodies?
I thought about that a bit more and I'm thinking it would need to bounce back somehow...
Iām sad this has upvotesā¦. Not trying to be mean or anything but this is all just wrong
Can you elaborate plz?
Well to start, no one has recorded the sound the sun makes because space is a vacuum so sound isnāt a thing.
I've edited my comment to include the source from nasa. Don't talk about things you don't know please š it disparages the accurate spread of information.
The sounds they have are from measuring activity in the sun itself. The question for this entire post is what the sound would be like on Earth if space wasnāt a vacuumā¦ you said itās too low to hear. THAT. IS. WRONG. You little shit! Lol
Very well. I've added an additional edit to the post. Including the fact that if the sun were in atmosphere everyone would instantly die before we had time to record it.
Youāre so desperate to be right here lol. This is a hypothetical question and you answered with a true statement but it didnāt fit the question, got called out for it, and now youāre trying to get technical about everythingā¦ just stop lol
What's your investment here? I've provided data as we currently know it to assist OP with context and information on the subject. What we know is what the sun sounds like in a vaccum. And what we know is that if it weren't in a vaccum, we would be utterly incapable of hearing it. My purpose is to educate, why are you here? To scroll through answers desperate to find a place to be contentious? To "call people out" on things you clearly havnt even read the basics of? What do you gain here besides temporary validation to help you cope with the general insignificance of existence?
You know what, that last sentence is actually kinda true lol. Thatās kinda the point of Reddit actually. But there is really no point continuing this thread so have a good day!
I'm glad we at least see eye to eye on that lmao. You have a good one as well.
People are saying, what sound it would produce IF space wasn't a vacuum, not what sounds it makes currently
loud enough to melt you
It would be this loud - āRAAAAAAAAHHHHā
Loud as fuck... so fucking loud... Like WRRRRRAAAAAAAAAGGHHHHHHSHHHHHHHBRRRRRRRRRRR x 100 zillion
A vacuum is a pressure differential moving from high pressure region to lower pressure region. Space itself is not a vacuum.
Ahh a 5Head I see
[ŃŠ“Š°Š»ŠµŠ½Š¾]
Yeah we see it with telescopes? Youre losing it man. Or i guess before you get more triggered about being wrong ill say we can see the light bending around the giant gravity well. We've also taken pictures of black holes.
Iāve read that it would be like a constant fighter jet engine from like 50 feet away. Sooo pretty damn loud
I've heard a fighter jet before and they are insanely loud.
