This is the scary sound of a black hole

A few days ago, NASA published the sound made by a black hole at the center of the Perseus cluster of galaxies. Now the Planetarium of the National University of La Plata (UNLP) replicated that publication on its networks and explained what it is about.

“What the National Aeronautics and Space Administration of the United States did was to translate astronomical data: they obtained frequencies of the pressure waves that the black hole emits and that cause waves in the hot gas of the cluster, and translated them into musical notes audible to humans“, they wrote in their networks.

The video that recreates this finding is creepy. “The location of this cosmic object is very important because it is immersed in a vast amount of gas from the galaxy cluster that provides the right physical medium for the waves emitted by the black hole to propagate and for us to be able to hear them,” explains Dr. portal.

As NASA describes, This cosmic object has been associated with sound since 2003 when astronomers detected that the pressure waves emitted by the black hole generated waves in the gas of the galaxy cluster in which it is located, which, through certain methods, could be translated into a sound audible to the human ear.

To do this they used the sonification What is it a technique capable of using astronomical and digital data captured by space telescopes to translate them into sound. Although such a process is not at all simple since it was necessary to extract the previously identified sound waves to resynthesize them and bring them to the audible spectrum for the human ear increasing them by 57 and 58 octaves above their actual pitch, that is, they are heard 144 quadrillion and 288 quadrillion times more than their original frequency
