Universal Sigh: Close to a B Flat
Newly uncovered sound waves are thought to have been produced by explosive events occurring around a supermassive black hole in Perseus A, the huge galaxy at the center of a cluster. The pitch of the sound waves translates into the note of B flat, 57 octaves below middle-C.This frequency is over a million billion times deeper than the limits of human hearing, so the sound is much too deep to be heard, and we have a lot of evolving to do.
