Astronomers have established that a black hole makes a sound that is in the note of a B-FLAT. The sound waves emanating from a super massive black hole are theorized to be the deepest notes found in the universe. With a frequency of 10 million years the wave is a B-FLAT that is 57 octaves below middle C. This is a pitch so low that the human ear doesn't have the ability to hear it. Scientists also theorize that the loudness of this sound is comparable to that of human speech. Isn't science fascinating?
