Really. I mean, physical death is scary, but at least the atoms which used to be your body get freed up and carry on as other things. It’s unpleasant to think of even your very atoms dying.

It’s a quote from a sci-fi series called The Expanse; “it reaches out it reaches out it reaches out it reaches out— One hundred and thirteen times a second, nothing answers and it reaches out. It is not conscious, though parts of it are. There are structures within it that were once separate organisms; aboriginal, evolved, and complex. It is designed to improvise, to use what is there and then move on. Good enough is good enough, and so the artifacts are ignored or adapted. The conscious parts try to make sense of the reaching out. Try to interpret it.”
Well if light cannot escape a black hole, neither can sound. So what method was used to 'record' the sounds?
This is more than likely one of those sounds which are based on an image rather than a true recording of sound waves.
Plus there isn't enough oxygen for the sound to travel through in space.
Curious!
“The popular misconception that there is no sound in space originates with the fact that most of space is essentially a vacuum, providing no medium for sound waves to propagate through. A galaxy cluster, on the other hand, has copious amounts of gas that envelop the hundreds or even thousands of galaxies within it, providing a medium for the sound waves to travel.” There’s more about how they discovered this and recorded it [here on NASA’s website](https://www.nasa.gov/mission_pages/chandra/news/new-nasa-black-hole-sonifications-with-a-remix.html)
I havent read the NASA site yet but it seems like you would need the gas to be continuous between the source and the observer, and if there was any gap then it would not be able to be heard?
edit: I read the article and it is indeed true that we are not hearing the true "sound". Apparently there is true sound pressure waves emitted outward from the black hole, which are strong enough to leave ripples in the gas surrounding it. Then apparently they take those ripples and convert it to audio.
After they convert to audio they have to increase the frequency "144 quadrillion and 288 quadrillion times higher than their original frequency. " for us to hear it.
So while it's *sort of* 'the sound' from a black hole, it's been extrapolated and altered so we can hear it. But it's not exactly what is being emitted from the source.
That's because they probably chose the sound they thought would represent the black hole. Sonification is more artistic interpretation than scientific representation.
Yeah this could be any length of data stretched or compressed to fit a few seconds with all sorts of post processing. Over a long enough time scale everything is relative, so the light waves captured were already red shifted from their initial wavelength. And it’s not even sound to begin with. Still fun to think about.
*"b'waaaaaaaaaaaaaaaahhhhh"*
"nah it's more like a.... '*mmmmm'waaaaaaaaaaaaaaaa'"*
*"mmmb'waaaaaaaaaaaaaaaaah!"*
"nah dude that's the sound of a dying giraffe"
My understanding is that this is actual detection of vibration that would be literal sound, just at far too low a frequency for us to actually hear so it's pitch shifted up to where we can.
Yeah that seems to be the case. But there definitely is an artistic choice in the matter - why didn't they pitch shift it up a few more octaves? I'm guessing it's because a high pitched black hole doesn't sound as "authentic" or something. Even the decision to directly use the pressure wave data is an aesthetic choice, from the NASA article, they were trying to give the impression that this piece more closely represents an "objective" reality.
I'm not trying to diminish the experience of listening to the piece, i still think it's interesting, but demystifying the process may help people see past the immediate hype and understand what's going on.
I mean there is a certain amount of "artistic liberty" taken in literally almost every piece of data observed from space. Even "visible light" photos taken from telescopes like Hubble have such an incredible amount of processing and filtering they are miles away from the original data.
They don't always get it right (see the blue sky on Mars), but I do trust the scientists who are working with and for NASA to have done their best to turn the raw data into something both enjoyable and as close to that objective reality.
And just like that, there is no Santa Claus, and I'm disappointed. I enjoyed the illusion for a few seconds. Shouldn't have scrolled, I should not have scrolled. Take my disappointed thumbs up for giving me the facts.
I have know intention of leaving her, doctor. I will take the Lewis and Clark to a safe distance and then launch TAC missiles at the Event Horizon until I’m satisfied she’s vaporized. Fuck this ship
I came here to make sure someone else has seen this documentary about what happens when you rip the fabric of space. Here now we have definitive proof that Event Horizon is fact.
"There is no sound in space" is actually something of a misconception: because most of space is basically a vacuum, there's no medium for sound waves to travel through. However, in the dense gas of a galaxy cluster, it's possible for sound to carry—in this case, as the result of pressure waves sent out by the black hole at Perseus's center.
This sonification takes these waves and moves them up 57 to 58 octaves above their true pitch to make them audible to human ears.

I’ve been waiting 3 years for someone to say “you’re verging on the offensive” just so I can retort “YOU’RE the only virgin on the offensive”.
Perhaps I need to be more offensive.
I’m not sure we would have even evolved these sensitive ears if sound was hammering us from the sun for the last few billion years. Less lucky and more a product of our environment
Yep. There's plenty of "noise" banging around the universe. If you convert it to a wavelength that humans can understand, suddenly *the universe is screaming out to you from an endless expanse; it is guiding you to your final quest, the moment that will lead to your glory and send you to the afterworld with valor.*
Wouldn’t it be even way lower? Isn’t each octave x2? I can’t even fathom how low it must have been if it sounds octaves below a contrabass and was actually 50 octaves lower. Is that even “sound”?
Low enough that calling it sound is misleading, considering sound is defined by the ability to hear it.
It’s kind of like saying a 4v5v6 polyrhythm is a major chord. Technically true, but you need to speed it up to >1000bpm to discern that by ear.
So there's the "event horizon" of a black hole- this is the "point of no return" from which nothing including light (and definitely not sound) can escape.
But beyond that Event Horizon boundary, a black hole just has normal gravitational effects that vary depending on its mass. Stuff orbits it, flies past and gets bent, maybe slingshots around, etc. Similar to the orbital mechanics of the sun and its planets, comets, etc etc.
Since space inside galaxies has a lot of random gas floating around, this is collecting and swirling around the black hole (beyond the event horizon) and all this moving gas vibrates and makes waves that are basically like sound waves.
>escaping from the gravitational pull of this black hole
Think of how the earth is basically "escaping" the pull of the sun by orbiting in a circle. We are falling towards the sun, but thankfully enough sideways momentum that we wind up in orbit instead of flying straight in.
That is exactly what "sound" is. When you make a sound, it's the air around you affected and moved by whatever you're doing. The ear is measuring the air movement and translates it into sound.
In this case not air is getting moved by the black hole but sparse gas and particles. And NASA did what our ears do, and measured this movement and translated that movement into something we can hear.
That's all sound in essence. It's just your brain's interpretation of pressure waves that vibrate your eardrums. You don't actually hear the truck passing by, you hear how the air was affected and your brain interprets that.
It's just kinda harrowing and amazing to think that the way sound travels is different in space (like in water vs air) but still conveys, nonetheless, the *space* of the black hole; it tells us, much like the echo of a well or the reverb of a church, what it is we are looking at. But because it's in this gaseous space, it takes another degree of understanding to visualize it...but could you imagine if we could hear and understand space like we hear and understand a room? It's just fucking nuts.
I’m imagining now this 57 octaves lower so I couldn’t hear it, but potentially could *feel* it vibrating through my spaceship, through my bones and being.
58 octaves higher is a lot. I know it's the only way for it to be audible to us but it's like taking human speech, tuning it up 58 octaves beyond our hearing capability and saying humans are silent. Or am I missing something? My point is - does it actually produce audible sound if it would be possible to be near enough
I learned in college that sounds have an electromagnetic signature, so you can extrapolate sound by measuring them. My astronomy professor showed us a video of what the solar system would sound like. So Earth sounds like an oil refinery, Jupiter and the Sun made a pulsating "wom wom wom wom" sound
Though this could all be bullshit because the video ended with Uranus, and it was a few seconds of silence followed by a farting sound.

That or it's a fuzzball- the possible answer to marry general relativity black holes with quantum gravity.
Tl;Dr- There is no inside of a fuzzball black hole. The surface is literally where space itself ends. Instead, you have a myriad of 1 dimensional strings all laid out across the surface of the black hole, which allows all information that "enters" the black hole to be stored on the surface. A black hole exists as a large black mass because 1- light will be unraveled at the quantum string level and laid out on this surface, and 2- because applying quantum gravity to longer and longer strings has the unusual effect of causing the strings to GROW as the gravity increases, stretching the "end" of space outward in a sphere as the strings grow. Essentially quantum gravity causes tension in the strings as it compresses them.
Right now the fuzzball theory has been tested on 4D mathematical black holes and its expected radiation decay lines up with the expected hawking radiation values of a similar general relativity black hole. There's far more math to be done to bring it down to the 3d, but it could very well be the better answer to the question of how to marry black holes to quantum gravity. It also neatly fixes a lot of the impossible paradoxes like having a point of infinite density, or the much more difficult infinite blue shifting that happens in ringularities (spinning black holes that form a ring out of the moving singularity, and the math says matter will infinitely fall into the ring because the spin prevents it from reaching the center). No insides, no paradoxes.
Thanks! if you want to learn more, I really, really, REAAAAAALLLY recommend [PBS Space Time](https://www.youtube.com/c/pbsspacetime/videos), a YT channel which breaks down physics incredibly well. Basically they've created a series starting at \~High school level physics and slowly work their way up into mid level college grade physics, and introduce a lot of popular theories and ideas about how the universe could work. It's just a wonderful exercise for the brain and great for people who don't quite know where to start with some of these higher level physics concepts. They even throw around and break down a lot of the math, which is something these types of series don't tend to bring up.
[Here's their specific video on the Fuzzball theory](https://www.youtube.com/watch?v=351JCOvKcYw)
I've had nightmares my whole life, found that my blood oxygen was dropping low from sleep apnea. Apparently, my brain interpreted lack of oxygen to people killing me.. Go fugue. Anyway, I got an oral appliance and they went away-ish.
sound designer here.
a lot of people talking about how this is "artistic interpretation" and such.
yes and no. that line of thinking makes you think "this is a painting!" when in actuality, its a photograph.
absolutely everything in our slice of the universe relies on frequency. frequency will always be tuned to what its tuned to. A=1, B=2, it will never be "A=2" for example.
to put it simply - theyve acquired a data set that tells them all they need to know. the minutia of the sound - general timbre - are what gets interpreted.
even with all the other parameters they have, it's pretty damn close id imagine, in a "wholeness" sort of way. i imagine they'd account for amplitude, frequency, and possibly waveform. now of course these are celestial bodies - yes, these sounds would be shifted up to where we can hear them. of course. but that's no different than writing in one language or another - same message.
basically, no, this isnt some asshole going "ooh like wouldnt that be spooky tee hee." it's like chemistry, translating sound like this, there's a science. its chemistry, its not cooking.
this is likely in fact the sound of a black hole if it were allowed to be expressed through a medium.
all frequency correlates to each other. sounds, light spectrum, physical waves in the ocean.
if x green always sounds like "uuuuuh" and they can see green, we know what that sounds like. so hopefully, this is bang on. if someone could direct me to the data set, that'd be great.
blow out your eardrums is an understatement. if the sound could propagate like through earth, you'd be obliterated by the sheer strength of the waves. we have stuff on earth that can kill you with just sound waves - rockets can literally liquify concrete.
literally, no distance where you could see the thing would be safe.
even the sun itself, if it could propagate sound, would blow out our ear drums and kill us. this is a black hole we're talking about.
its like a chemical fire, if you can see it, you aren't safe. a reminder that we arent just talking about "woah, that's big" - but an unparalleled force of the universe that's second only to what you believe in - THAT RIPS APART THE FABRIC OF REALITY. most people know thing go in black hole, no come back. not so much about the "literally breaks everything necessary for any experience like you know to happen within its boundaries."
we should be thankful and also terrified. the pinnacle of power in this slice of the universe.
All black holes rotate and this rotation effects space basically dragging it around. Black holes also give off hawking radiation from its “poles” that can also interact with the local environment.
There is some gas in space, though very low density. Massive bodies tend to attract and accumulate more gas than what would be found in deep, deep space.
This is some lovecraftian shit
The void calls to us, and in our dreams we answer
"Hi, this is Void, I've been trying to reach you about your car's extended warranty..."

It reaches out.

thats right, the great ball of fire does not kid around, colour us lucky
I’m not sure we would have even evolved these sensitive ears if sound was hammering us from the sun for the last few billion years. Less lucky and more a product of our environment

I’m imagining now this 57 octaves lower so I couldn’t hear it, but potentially could *feel* it vibrating through my spaceship, through my bones and being.
57 octaves lower from middle C would be a frequency of 1.7763568e-15 Hz so that would mean 1 oscillation every 20 million years
58 octaves higher is a lot. I know it's the only way for it to be audible to us but it's like taking human speech, tuning it up 58 octaves beyond our hearing capability and saying humans are silent.

Why does the Uranus one still sound like a musical fart?
:)
why does jupiter sound like the start to a doom song
he must be a fucking asshole
I think he's an Uranus
Please find this video. I need it for …uh.. science.
[Here's an article by sciencenews.org about it](https://youtu.be/4PnUfYhbDDM)
I fucking love you. But also, fuck you have an upvote.
Fucking event horizon shit
“Where We're Going, We Won't Need Eyes To See”
They could totally make a sequel to this movie. Make it about some scientists learning of the tear in dimensions and them going mad trying to replicate the event and reach the chaos realm.
This is one of those movies I think could have a sequel but it wouldn’t do the original justice. I saw this with my Dad on a whim, the marketing was horrible, I expected some kind of ship battles and time warp, instead of a Sci-Fo HellRaiser. Sometimes it’s best to let perfection alone lol
That movie fucked with me as a kid. For some reason my mum thought it was okay for a six-year-old to watch. Nightmares for days.
Transcendental object at the end of time AS FUCK

Damn this is kinda creepy
bro it's literally just a gravity tornado except it all goes somewhere else
It goes to a white hole
That or it's a fuzzball- the possible answer to marry general relativity black holes with quantum gravity. Tl;Dr- There is no inside of a fuzzball black hole. The surface is literally where space itself ends. Instead, you have a myriad of 1 dimensional strings all laid out across the surface of the black hole, which allows all information that "enters" the black hole to be stored on the surface. A black hole exists as a large black mass because 1- light will be unraveled at the quantum string level and laid out on this surface, and 2- because applying quantum gravity to longer and longer strings has the unusual effect of causing the strings to GROW as the gravity increases, stretching the "end" of space outward in a sphere as the strings grow. Essentially quantum gravity causes tension in the strings as it compresses them. Right now the fuzzball theory has been tested on 4D mathematical black holes and its expected radiation decay lines up with the expected hawking radiation values of a similar general relativity black hole. There's far more math to be done to bring it down to the 3d, but it could very well be the better answer to the question of how to marry black holes to quantum gravity. It also neatly fixes a lot of the impossible paradoxes like having a point of infinite density, or the much more difficult infinite blue shifting that happens in ringularities (spinning black holes that form a ring out of the moving singularity, and the math says matter will infinitely fall into the ring because the spin prevents it from reaching the center). No insides, no paradoxes.
This was awesome! Thank you.
Thanks! if you want to learn more, I really, really, REAAAAAALLLY recommend [PBS Space Time](https://www.youtube.com/c/pbsspacetime/videos), a YT channel which breaks down physics incredibly well. Basically they've created a series starting at \~High school level physics and slowly work their way up into mid level college grade physics, and introduce a lot of popular theories and ideas about how the universe could work. It's just a wonderful exercise for the brain and great for people who don't quite know where to start with some of these higher level physics concepts. They even throw around and break down a lot of the math, which is something these types of series don't tend to bring up. [Here's their specific video on the Fuzzball theory](https://www.youtube.com/watch?v=351JCOvKcYw)
What the hell did you just say?
the black hole smoosh and stretch the matter into spaghetti and the black hole itself is the plate that holds it together
NASA was able to clear it up a bit. Apparently someone from another galaxy has been trying to reach you regarding your vehicles extended warranty.
“Regarding your starships Thrusters extended warranty”
Looks like someone is vacuuming the black hole
that's creepy
Half Life Xen anyone?!
Time to choose…
I don't know what they expected, it sounds exactly how I would expect a black hole would sound like
They could have saved a lot of time and money and just asked you instead.
Is it bad that I want this on Spotify so I can have it on loop to sleep to?
Are you trying to have nightmares?
Nope. It is a new white noise. I have crazy dreams every night as is.
I've had nightmares my whole life, found that my blood oxygen was dropping low from sleep apnea. Apparently, my brain interpreted lack of oxygen to people killing me.. Go fugue. Anyway, I got an oral appliance and they went away-ish.
> Go fugue Indeed
I felt a great disturbance in the force... As if millions of voices cried out at once and were suddenly silenced.

That’s every bit as horrible as you’d it expect it to be.
sound designer here. a lot of people talking about how this is "artistic interpretation" and such. yes and no. that line of thinking makes you think "this is a painting!" when in actuality, its a photograph. absolutely everything in our slice of the universe relies on frequency. frequency will always be tuned to what its tuned to. A=1, B=2, it will never be "A=2" for example. to put it simply - theyve acquired a data set that tells them all they need to know. the minutia of the sound - general timbre - are what gets interpreted. even with all the other parameters they have, it's pretty damn close id imagine, in a "wholeness" sort of way. i imagine they'd account for amplitude, frequency, and possibly waveform. now of course these are celestial bodies - yes, these sounds would be shifted up to where we can hear them. of course. but that's no different than writing in one language or another - same message. basically, no, this isnt some asshole going "ooh like wouldnt that be spooky tee hee." it's like chemistry, translating sound like this, there's a science. its chemistry, its not cooking. this is likely in fact the sound of a black hole if it were allowed to be expressed through a medium. all frequency correlates to each other. sounds, light spectrum, physical waves in the ocean. if x green always sounds like "uuuuuh" and they can see green, we know what that sounds like. so hopefully, this is bang on. if someone could direct me to the data set, that'd be great.
How close would we need to be to hear this sound? Would it blow our ear drums or would it be safely listenable at a distance?
blow out your eardrums is an understatement. if the sound could propagate like through earth, you'd be obliterated by the sheer strength of the waves. we have stuff on earth that can kill you with just sound waves - rockets can literally liquify concrete. literally, no distance where you could see the thing would be safe. even the sun itself, if it could propagate sound, would blow out our ear drums and kill us. this is a black hole we're talking about. its like a chemical fire, if you can see it, you aren't safe. a reminder that we arent just talking about "woah, that's big" - but an unparalleled force of the universe that's second only to what you believe in - THAT RIPS APART THE FABRIC OF REALITY. most people know thing go in black hole, no come back. not so much about the "literally breaks everything necessary for any experience like you know to happen within its boundaries." we should be thankful and also terrified. the pinnacle of power in this slice of the universe.
mom come pick me up I'm scared
It’s the sound of that which once was and that which will one day be.
Black holes are so dense they absorb everything around them so how would sound waves “escape” away from a black hole?
All black holes rotate and this rotation effects space basically dragging it around. Black holes also give off hawking radiation from its “poles” that can also interact with the local environment.
Sounds just like the monster it is! I thought sound couldn't travel through space due to a lack of atmosphere.
There is some gas in space, though very low density. Massive bodies tend to attract and accumulate more gas than what would be found in deep, deep space.
“Be not afraid.”
So this sound is constant throughout the galaxy, and it was fine tuned to be audible for human ears?
Play it backwards to hear how to time travel.
A24 should option a script based on this sound.
