Listen: What does a black hole sound like?
NASA has an answer
Although sounds cannot travel through space because of the void, it turns out that space itself makes sounds, and they are not pleasant at all.
NASA recently released the "voice" of a black star located at the center of the constellation Perseus. This is what it sounds like
Voila system!

The common perception about sound in space is that space is absolutely still and quiet, simply because of the void (vacuum) where sound waves cannot travel.
But it turns out that space itself has sounds - and they are quite terrifying.
Yesterday (Sunday), NASA's Twitter account dedicated to distant stars shared a rather horrifying sound file (you are welcome to listen to it for yourself below), which represents real sound waves moving through gas and plasma in the black hole-centered Perseus cluster 250 million light years away. from Earth. The reason for the existence of the sound is that this cluster has so much gas that the vibrations in it actually create a sound, which the people of the American space agency were able to pick up from Earth. They amplified and mixed it, and this is how it sounded.
This is what a black hole sounds like
The misconception that there is no sound in space originates because most space is a vacuum, providing no way for sound waves to travel.
A galaxy cluster has so much gas that we've picked up actual sound.
Here it's amplified, and mixed with other data, to hear a black hole!

Although the acoustic vibrations were discovered back in 2003 by NASA's Chandra X-ray observatory, it has never been possible to produce sounds adapted to the human ear, until now. "In some ways, this sound creation is a first of its kind, because it is based on information collected in "Chandra".
The "sound" made by the Perseus saber has actually been heard for the first time," the space agency explained in its official announcement.
And here's the reason for the difficulty: these sounds are 57 octaves below the middle octave, making the black hole very deep-sounding! To make them For our ears to hear, the scientists raised the frequency by a factor of a quadrillion (that's a million billion).The resulting sound is still chilling.
