Edited by: Izkhanilov on 06/03/2009 04:09:44 On September 9th, 2003 Change X-Ray observatory discovered actual sound waves being emitted from the resonation of a supermassive black hole near the center of the Perseus star cluster. The astronomers working at the observatory gathered this information from observing an outward ripple pattern in the clouds surrounding the black hole. The sound had thus far traveled hundreds of thousands of lightyears from the black hole, in all directions, creating this ripple pattern in the gas clouds.
Here's the full story: Black Hole Symphony
As for the sound, it's low ... Very low. So incredibly low that it could only be detected by the ripples formed in the gas clouds. The exact depth of the note takes the record as the lowest sound ever to be generated by any object in the universe. The 'note' resides a whopping 57 octaves below the pitch of middle-C on a normal piano. Middle-C has a frequency of 261.63Hz, and given the amount of decrease between octaves, that would make the frequency of the black hole's resonation approximately 20x10^-14. In long terms, that's 0.0000000000002Hz. The limit of human hearing is 20Hz. That pitch is fifty-seven octaves below Middle-C, located here:
Fifty-seven octaves is much lower than anyone could ever hope to hear, and just the thought of a note so low is mind boggling. This sound is so impossibly low and ominous that not even subsonic scanners could pick it up. Here are some images of what the rippled clouds look like, the supermassive black hole placed at the center as the globe of light
I bring this topic to EVE-GD because it's so mind-bogglingly ominous. Try to imagine a sound as low as that.

I will most certainly not "get low" on your "black hole"

Definately. The OP spends 5 years preparing a nice post complete with pictures and everything, and it is killed in the first reply.
Awesome.
Sig is now EVE related. Happy mods?

Interesting, that'd be slightly higher in pitch than James Earl-Jones's voice then yes?
More seriously that is very very cool, thanks for posting.

The lowest sound ever has already been generated *years* ago when James Earl Jones' voice broke. But credit where it's due, that sound is pretty damned low

To be an ass, that isn't actually a sound.
Sound is a vibration through air, liquid or a solid object, and to quote Wikipedia (all hail);
"...composed of frequencies within the range of hearing and of a level sufficiently strong to be heard, or the sensation stimulated in organs of hearing by such vibrations"
What you've got coming from that black hole is an incredibly low frequency waveform oscillation.
The problem I'm having here is how these scientists, who have substantially more brain than I do, neglected to see the error of their statements.
No doubt they mentioned it as the "Lowest note in the Universe" to give it perspective, as the average joe finds it easier to imagine.

That's all any sound or electro-magnetic wave is bro, it's just the frequency that seperates one from the other. 20Hz-20kHz is about the range of human hearing. 100MHz is commercial radio stations (using FM), X-Rays are like 1x10^9 or 10^12 Hz IIRC. Sonar as I understand it is in about the 0.0000X-20Hz range. That frequency *is* a sound wave, it's just below anything we or most technology could *hear*. -------------

I think his point is that sound is not an electromagnetic wave. Sound absolutely requires a medium to transmit itself. Since space is a vacuum there is nothing to transmit sound. A nuke could go off a mile from you in space and you'd never hear it.
The EM spectrum however transmits just fine through a vacuum.
EDIT: I guess I should add the article suggests the black hole is embedded in a colossal gas cloud (which is where they are seeing the ripples). If that is the case then doesn't the gas cloud represent the medium which transmits the sound?

Have to pick you up on 2 points:
1. Space is not a "hard" vacuum. 2. If a nuke did go off a mile from you in space (and you somehow survived), you would hear it - there's still a shock-wave generated which would cause your eardrums to respond.

if you say a average piano's octave is 15cm (6 inches) then the piano ould have to be about 9 meters wide to generate that sound.... wow, nice find mate. Resistance Is Futile. |

Not only would it have to be nine meters long, proportionally, it'd have to be just as deep. And the cord would have to be just that much longer. The piano would end up being bigger than the concert hall! And only the dogs could hear the lower octaves.

If a black hole is vibrating in space, and no one is there to hear it, does it make a sound?

If a man makes a choice, and there are no Women around, is it still the wrong choice?

Sorry to necro the thread but just came across it again and wanted to respond.
1) You are correct space is not a "hard" vacuum (such a thing is impossible anyway) but for our purposes here it may be considered as such. The average density of outer space is on the order of something like 10 atoms/m3. That is far too sparse a medium to propagate a soundwave in.
2) Actually no it wouldn't. Don't take my word for it though, see what NASA says:
Quote: If a nuclear weapon is exploded in a vacuum-i. e., in space-the complexion of weapon effects changes drastically:
First, in the absence of an atmosphere, blast disappears completely.
Second, thermal radiation, as usually defined, also disappears. There is no longer any air for the blast wave to heat and much higher frequency radiation is emitted from the weapon itself.

I'd say sounds are in fact nerve impulses. Caused by waves, but not actually waves per se.
Or are those electric impulses considered waves?
