NASA shares the terrifying sound of a black hole on Twitter | Sciences
In recent months, we have not only been provided with new images of the black hole, but an audio portion as well. How could such a black hole sound in space? creepy to hear.
“The misconception that there is no sound in space stems from the fact that space is usually a vacuum, where sound waves cannot travel,” NASA wrote on Twitter on Sunday. “But a group of galaxies has so much gas in it that we actually pick up the sound. In this case, it’s amplified and mixed with other data to hear a black hole.”
The sound of a black hole is completely ghostly. They come from real sound waves from the supermassive black hole in the center of the Perseus galaxy cluster, which is more than 200 million light-years away. NASA has edited the sound so that human ears can hear it. The audio was mixed with “other data” and amplified.
NASA’s Chandra X-ray Observatory released the audio clip in May during Black Hole Week. Now the space agency has sent it to the world via Twitter and immediately received a lot of feedback. Several netizens reported that the black hole looked exactly as they expected: creepy. “I somehow knew that a black hole would look like terrifying ghosts rather than gentle ocean waves,” Asher Honikmann wrote on Twitter. Another wrote on Twitter: “If you raise the volume of the black hole, it is as if hundreds of tormented souls are being dragged under a lake of fire.” It seems that someone is also recognizing “Echoes” of Pink Floyd, and another music lover joked that it was a new work by Icelandic artist Björk.
What is a black hole?
A black hole is basically what remains after a star explodes, a star whose mass is greater than the mass of the Sun. During such an outburst, the star briefly produces as much light as the entire galaxy to which it belongs. Then go black forever. That is why black holes are called frozen stars before 1964. Moreover, the core of the explosion becomes so compact that a black hole forms. Since nothing can escape from black holes – only some of them can fall into them – their mass grows over time.
