Default Black Hole Sings a Tune!!

Looks like Black Holes can sing...even though the note given off by this hole, a B-Flat, is more than a million billion times deeper than you can hear.

I wonder what would happen if you heard that note...I'll break out the violin to go with it! :-({|=

Or what about that Soundgarden song that could be considered the black hole national anthem?

"Black hole sun
"Won't you come
"And wash away the rain"

Yes; does anybody have a good idea about how these gigantic, fantastically low wavelength waves are propagated in the interstellar or intergalactic medium?
There is only about one to six molecules of hydrogen etcetera per cubic metre; how can they carry energy like this?

They seem to be observing the effects that the sound waves are having on the surronding mass. What is being observed, apparently, is the subtle change in light intensity at a rate equivalent to a very low octive Bb note.

This Bb is complexing as I was told as a kid to avoid black holes otherwise I would be A flat minor! (sorry, had to do it)

The frequency, and I'm no math whiz, is 3.2e-15 Hz for a Bb note 57 ocataves below a middle Bb. (using middle Bb @ 466.2 Hz).

This is about 10 million years to "hear" one wave.

I prefer more lively music. :P


Don't Saturn's rings also have some sort of wave pattern??? Could not find this out but seem to recall something about it.

In the movie, "Jumping Jack Flash" with the ubiquitous Whoopi Goldberg, B-flat was the key to solving the story's mystery.

As a professional contrabassoonist (and brand-spankin' new member of this board), I must say that I've never been as jealous of anything as I am of this black hole. Just *imagine* what Stravinsky could have done with that! 8)

I hope Metallica and others don't turn their amps to compete. [-X

I'm wondering if you right on this.

Is the black hole going nuts every 10 million years or is the period due to the thin density the wave is moving through?

This topic looks interesting but deep (assuming we can advance past the melodious comedy)

Did Chandra see x-ray emissions to observe the wave? If so...wow. It aughta then be the largest object of x-ray emissions. Yes?

If so, how did that wave get that energy and keep it for tens of millions of years?

Any black hole pros around?
