It is essentially an illusion that there is no sound in space. We generally believe that it is not possible for space to be composed of empty space and for sound waves to travel in space. However, there is so much gas in a galaxy cluster that it is possible to obtain sounds with the right methods. He did exactly that to record the sound of a black hole at NASA.
Like out of a horror movie
The black hole sound shared by NASA a while ago comes from the Perseus galaxy cluster. Astronomers from the Chandra X-ray Observatory have produced this startling sound by pulling the pressure waves created by the black hole to frequencies that humans can hear.
Space tests of the National Hybrid Propulsion System were successfully carried out
NASA actually shared this audio-based video in May and made a detailed explanation. It was discovered that the pressure waves created by the black hole in the center of the Perseus galaxy cluster were traveling on the hot gas of the galaxy. It is well below the threshold that exposed people can hear under normal conditions. Therefore, these original frequencies need to be amplified to a level that humans can hear. According to the reports, in order for us to hear the waves emitted by the black hole, the scientists increased the frequencies they recorded by more than 144 quadrillion times. The result looks like it came out of a horror movie.
