Once you hear this — you can’t unhear it.
The sound of a black hole has proven to be slightly terrifying. Like something that would be edited into a Halloween soundtrack.
NASA shared the 34-second clip above of the Perseus Galaxy Custer — which is about 240 million light-years away from earth.
Scientists say the black hole sends out pressure waves that cause ripples in the hot gas which can be translated into a note.
The actual note is one that humans can’t hear. It’s about 57 octaves below middle-c, but experts at NASA say they shifted the note so we could hear it — amplified it, and then mixed it with other data they have about black holes.
