sound waves and black holes

[Megan]

Can we hear sound that pitch?....


The lowest note in the universe is caused by the rumbling of a black hole in the Perseus galaxy - 57 octaves below middle C

We definitely can't hear that , but I think the bass in my schola cantorum might be able to sing lower than that

How interesting!

57 octaves below middle C? It would be nice to have the beginning of the Firebird played that low! Only it couldn't be heard.

Now, black holes are my thing !! I love this stuff, even though the science is far above my head!!
Not entirely on topic, but did you know that the galaxy called Andromeda is on a collision course with our own Milky Way? In about several billion years or so our two galaxies will obliterate each other! I find that fascinating.
Now, the question is: what music to accompany this stellar catastrophe?
Makes a change to the usual "Desert Island Discs", wouldn't you say?
My suggestion: something orchestral by Scelsi, like this: https://www.youtube.com/watch?v=AsTX7Vm7zoM

That piece works for me. Thank you for sharing that!

Yes, I thought it very fitting, and a great piece.

Back to black holes, here's an article about a recent discovery of a super massive black hole near the centre of our Milky Way:

As I said above a few posts ago, the science is way above my head, but am I wrong in saying that in time (lots of time!) we will eventually be sucked into this gaping stellar maw?
Imagine that!
Any other suggestions for suitable music? Methinks Brahms doesn't quite fit the bill.
How about the closing passage of the 1st movement of Beethoven's 9th?

Or the closing passage of the 1st movement of Bruckner's 9th?

Unlikely. Black holes are powerful, but our galaxy is incomprehensibly large.

Do I detect some similarities between the Beethoven passage and the Bruckner? I have never heard these before one after another. (Even the cat liked it.)

Schrödinger's?

Schrödinger's?

Which tune is radioactive and which tune is poisonous?
