If a black hole devours a planet and no one is around to hear it, does it still make a
sound?
Physicists and astronomers have been trying to map astronomical date through sound for
decades — and now we can finally listen to a black hole scream into the void.
Earlier this month, NASA released the first recordings, or sonifications, of what two
black holes sound like — and it's just the kind of noise astronomers and science fiction
buffs were expecting: eeire, ethereal, and aurally extraordinary.
