NASA created a haunting audio clip of sound waves rippling out of a supermassive black hole, located 250 million light-years away.
The black hole is at the center of the Perseus cluster of galaxies, and the acoustic waves coming from it have been transposed up 57 and 58 octaves so they're audible to human hearing.
@NorthernInvader imagine what the original frequencies are…the sound of galaxies rumbling through the universe….
@NorthernInvader that’s wild
@NorthernInvader Creepy😬
