Here's what a supermassive black hole sounds like

Scientists have produced an audio clip from acoustic waves propagating through the gas around a supermassive black hole.
The eerie audio, which originates from a black hole 250 million light-years away, was produced through a process known as sonification which involves turning data into sound.

While the actual sound would be inaudible to human ears due to its super low pitch, the clip has been enhanced by bringing the notes up several dozen octaves so that it is possible to hear them.

The resulting audio is undeniably eerie - a sort of otherworldly howling that's difficult to describe.

You can check out the clip for yourself in the video below.

Next they'll announce that they've also detected an odd smell emitting from the hole.

I might be missing the point, but i didn't think you could hear sounds in space, i thought soundwaves didn't travel through space.

Looks to me like these are just sounds generated from images, Fruity Loops (FL studio) had such synth for years.

No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel. so .... perhaps sound can exist inside the black hole...(I don't see how) ...and no one has a way really to 'hear' them even if they did. But they expect us to just believe everything they say. smh

Maybe you should have first read the article. Quote from the LadBible link: "The popular misconception that there is no sound in space originates with the fact that most of space is essentially a vacuum, providing no medium for sound waves to propagate through. "Agalaxy cluster, on the other hand, has copious amounts of gas that envelop the hundreds or even thousands of galaxies within it, providing a medium for the sound waves to travel." Interestingly, sound has been associated with this black hole since 2003, after astronomers discovered it sent out pressure waves that produced ripples in ... [More]
