Wanna Hear What A Black Hole Sounds Like?

This week, NASA released real audio from a Black Hole in the Perseus galaxy cluster.

NASA said, "Astronomers discovered that pressure waves sent out by the black hole caused ripples in the cluster’s hot gas that could be translated into a note – one that humans cannot hear some 57 octaves below middle C."

NASA added, "The popular misconception that there is no sound in space originates with the fact that most of space is essentially a vacuum, providing no medium for sound waves to propagate through. 

The statement continued, "A galaxy cluster, on the other hand, has copious amounts of gas that envelop the hundreds or even thousands of galaxies within it, providing a medium for the sound waves to travel."
