"Black Holes" the Musical

[Solar]

Explain those SOUNDS please...

It seems to be an interesting analogy. However, it also appears to be more 'black hole physics' vicariously assimilating any and everything within its grasp in an attempt to lend support to the failed mechanism. See also "Cosmic sound Waves Rule"

For years astronomers have tried to understand why there is so much hot gas in galaxy clusters and so little cool gas. Hot gas glowing with X-rays ought to cool because X-rays carry away some of the gas' energy. Dense gas near the cluster's center where X-ray emission is brightest should cool the fastest. As the gas cools, say researchers, the pressure should drop, causing gas from further out to sink toward the center. Trillions of stars ought to be forming in these gaseous flows.

Yet scant evidence has been found for flows of cool gas or for star formation. This forced astronomers to invent several different ways to explain how gas contained in clusters remained hot. None of them were satisfactory.

Black hole sound waves, however, might do the trick.- "Black Hole Sound Waves"

The above statement not only shows the failed mechanism but also points to the fact that black hole theorist constantly have to "invent" other scenarios because observation and evidence refuse to to fit the theory.

So now you have the situation wherein nothing else worked and as usual the "black hole" theorist, desperate for anything that might work, try to reel in the properties of acoustics to account for the production "hot gas" in a galaxy 250 million light years from earth and we get "black hole acoustics". What has become of astronomy and astrophysics that an acoustical analogy "... might do the trick."? Physics doesn't need, nor should it require such "tricks" in order to give account observations.

"If this black hole wasn't making all of this noise, M87 could have been a completely different type of galaxy," ...

The only "noise" I can hear stems from the mouths of those who put this theory forth and within the same article sight observations that run contrary to the whole scenario:

Other remarkable features are seen in M87 for the first time including narrow filaments of X-ray emission -- some over 100,000 light years long -- that may be due hot gas trapped by magnetic fields. Also, a large, previously unknown cavity in the hot gas, created by an outburst from the black hole about 70 million years ago, is seen in the X-ray image.

"We can explain some of what we see, like the shock wave, with textbook physics," said team member Christine Jones, also of the CfA. "However, other details, like the filaments we find, leave us scratching our heads." - "Chandra Reviews Black Hole Musical: Epic But Off-Key"

... narrow X-ray emitting filaments would correspond to the cosmic scale "lightning" you've mentioned but sound waves aren't going to account for their presence as the article clearly shows. The "ripples" in the X-ray pattern is due to an electrical explosion occurring within various types of plasma for the region in question. The "look" like sound waves but the pattern is discordant due to electric "flux".

"We've known that a black hole can give off energy as light and heat and now we are seeing a third way -- sound," ... - A song no human ear can hear

They "look" like sound waves as sound waves are represented via graphical depictions but the pattern is discordant due to variations of electric "flux".

How is it that an astrophysicist or astronomer looking through 250 million light ears of plasma of varying densities at a galaxy of even more dense plasma not relate these sounds to what they are; plasma waves, ion-sound waves in dusty plasma etc. It seems that it would have a different dynamic as opposed to simply "look"-ing like accustomed sounds waves depicted in air at B flat.

As a musician I like this. It is just as inappropriate to deny sound as a fundamentally important aspect of the universe as it is to deny electro-plasma dynamics. But "black hole physics" is bastardizing it like it does with everything else it tries to assimilate.

Now before you respond to this please calm down. If you don't want rebuttals to "sacred cows" then please don't post them.
