NASA Announces ‘Black Hole Sound’ Audio File
On the 22nd, NASA announced a sound file called “Black Hole Sound” on its official Twitter. NASA said that because most of outer space is in a vacuum state, theoretically, there is no way to hear any sound, but scientists are 240 million light-years away. , The black hole in the Perseus cluster of galaxies found a large amount of gas and pressure waves. Through the propagation of the gas, it was mixed with other data collected by NASA to translate and sound, and the “black hole sound” appeared.

Weird, mysterious sound
In fact, the sound of a black hole is so low-frequency that humans cannot hear it. NASA used the latest technology to increase the sound wave data by 57 octaves, and a low and eerie audio file came out. Many netizens had goosebumps after listening to it, thinking that the sound was as incredible as a mysterious universe, and some felt it was roaring like a beast, and this post by NASA quickly aroused discussion, and 460,000 people have liked it so far.

However, some people said that in fact, this sound was very healing, and it made people feel closer to the unknown universe. Maybe black holes are out of reach for us, but because of NASA’s sharing this time, there is an extra point. learn!
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! pic.twitter.com/RobcZs7F9e
