Nasa releases recording of 'lowest note in universe' from inside a black hole
In science fiction films, they usually sound horribly ominous, but in reality, it’s oddly like synthesiser music
Nasa has released a new ‘sonification’ of ripples from the black hole at the centre of the Perseus galaxy cluste
Since 2003, it’s been associated with sound, because astronomers discovered that pressure waves sent out by the black hole
The note emitted is one that humans cannot hear some 57 octaves below middle C
Now a new sonification brings more notes to this black hole sound machine
it revisits the actual sound waves discovered in data from Nasa's Chandra X-ray Observatory.
The sound waves were extracted in radial directions, that is, outwards from the centre.
