That’s how scary a black hole sounds. This sound recording by NASA impressively proves that space is not quiet. The US Federal Space Agency wrote on Twitter: “The misconception that there is no sound in space stems from the fact that most of space is a vacuum in which sound waves cannot propagate. There is so much gas in a cluster of galaxies that we have heard sound.” The scientists found that the pressure waves emitted by the black hole cause ripples in the hot gas. NASA was able to convert these waves into sound. However, the recorded sound waves are not audible to humans because the original sound is much too deep. So NASA edited the recorded footage to make it audible to people. The result is this eerie sound.
