Black hole singing B flat - lowest known note in the universe

[AreaCode707]

Bb is "57 octaves below the middle C at the middle of a standard piano keyboard"

i heard that on NPR yesterday... pretty interesting! It is also the LONGEST playing note known.

That's pretty cool. If you could hear a note that low, would we be able to hear it here on Earth?

 

[Azraele]

Neat. 🙂

Huh, that's an interesting question. Since they can observe it, apparently the waves are getting this far.

That's what I was thinking. And they said that the intensity was the equivalent of human speech. Presumably they meant for when the waves reach here.

no... sound is a pressure wave through a medium... the vacuum of space has no medium for the waves to travel through... they're basing this whole note on the assumption that you could float right next to the clouds of matter without any type of pressure suit and "hear" the sound generated by the waves of matter hitting you at regular intervals... so to be able to hear it on earth would require those waves of matter to travel all the way to earth undiluted, which just isnt gonna happen😉

lol, that's awesome! I miss reading geek news like this.

And if we could actually tune our ears to hear it...we'd be hearing a whole lot more than that, so I don't think you want that ability. One ripple of this sound is 30,000 lightyears. 186,000 * 60 * 60 * 24 *365.25 = 5869713600000 miles between each crest then, unless my math is wrong. Depending on the frequency, we'd be able to catch anything from under 20hz (average dropoff for human hearing) to that. ouch.

<---Has a feeling his reasoning is off. It's early for me 🙂

The article says they guessed the note based on periodicity of these pressure jets and a guess of what the environment is like over there (e.g. a James Earl Jones may sound like a chipmunk on PlanetX because of the atmosphere). Nothing has "reached" here other than x-ray observations.

😱 I read the title worng... I thought this was about Black Hole Sun... you know the soundgarden song.. 🙁

Bahh... nmusic otes... I play drums.. drummers don't need notes... we barely use 4 of them 😛

 

[LordThing]

So, black holes are just one long fart joke?

 

[thebestMAX]

Hope the Elephants cant hear it. Would drive them nuts.

You'd need a helluva subwoofer to play that! 🙂

BTW, those guys that sang Lonesome Valley in O Brother Where Art Thou could come close 😉

Anybody know what the previous record holder was and where it was found? I'm more curious to see what the lowest note on Earth comes from.

Da Peseus clusta gots da mad gangsta beats, yo.

Your toaster could play it, since the waveform is roughly DC. 😀
