As as bass player, I'm into those low, low loooooowww notes; the ones that make your chest shake, and your bowels do the rhumba.So imagine my delight today when NASA informed me that their Chandra X-ray Observatory detected, for the first time, a deep, deep tone rumbling from a supermassive black hole."In musical terms, the pitch of the sound generated by the black hole translates into the note of B flat," NASA says. "But, a human would have no chance of hearing this cosmic performance because the note is 57 octaves lower than middle-C."For comparison, a typical piano contains only about seven octaves. At a frequency over a million billion times (below) the limits of human hearing, this is the deepest note ever detected from an object in the Universe."
