NASA captured the ‘Music’ from a black hole
Could you imagine the sound of a black hole? Or even imagine that it makes sounds? Indeed, many believe that absolute “vacuum” silence reigns in space.
NASA disproved these misconceptions and gave us the opportunity to hear “space music”.
“The misconception that there is no sound in space originates because most space is a ~vacuum, providing no way for sound waves to travel. A galaxy cluster has so much gas that we’ve picked up actual sound. Here it’s amplified, and mixed with other data, to hear a black hole!”, – official Twitter of the National Aeronautics and Space Administration.
Scientists have known since 2003 that the black hole at the center of the Perseus galaxy cluster is associated with some sort of sound, NASA said, because there is so much gas in the surrounding galaxy cluster. Astronomers discovered the pressure waves sent out by the black hole were causing ripples in the hot gas. Those vibrations could be translated into a musical note, but the note is far too low for humans to hear, some 57 octaves below middle C.
So the signals were adjusted into the range of human hearing, scaled upward by 57 and 58 octaves above their true pitch. NASA originally released the “remix” in May. Another way to put this is that they are being heard 144 quadrillion and 288 quadrillion times higher than their original frequency
On Twitter, some users are already presenting the record as the sound of some black metal band.
