NASA shares the sound of a black hole and it sounds as scary as you can imagine

The idea of ​​a black hole gives us a mental picture of an inescapable infernal place. We imagine a terrifying place so powerful that it “swallows” whatever falls into gravitational space. The sound of this place must also be hideous.

In space, even if you scream, no one will hear you. Unless the scream is coming from a supermassive black hole. NASA shared this sound.

NASA allows us to hear sound from behind ... from a black hole

previously We hear the sound of the sunHey The voice of perseverance on your journey In deep space to Mars The sound of a devouring black hole A star, the sound made by the Earth's magnetic field and even a sound The sound of the aurora borealis.

Now, NASA has shared what the agency described as the sound of a black hole, available to human ears in audible form.

But then, does sound propagate in space?

This question, "How does sound travel in the vacuum of space," is answered by NASA, in a very brief explanation.

The misconception arises that there is no sound in space because most of space is a vacuum, and it does not provide any medium for sound waves to travel.

A group of galaxies contains so much gas that we have already discovered the real sound. Here it is amplified and mixed with other data to hear a black hole.

NASA said in a post dedicated to exoplanets that tweeted.

The group of galaxies that propagates this sound we can "hear" is the Perseus, a group of galaxies in constellation Perseus.

This data was provided by Chandra X-ray Observatory from NASA and Recording edited in May For the US space agency's Black Hole Week.

As NASA explained at the time:

Astronomers have found that pressure waves sent out by the black hole cause ripples in the cluster's hot gas that can be translated into observation — humans can't hear 57 octaves below middle C.

The slack velocity of this mass is 5,366 km/s and its diameter is 863′. It is one of the most massive objects in the known universe, containing thousands of galaxies immersed in a huge cloud of gas worth millions of dollars.
