What’s the Sound of One Black Hole Singing?

What is the tone that a black hole makes when it sings? It’s a sound so low that it will send chills up your spine. The tone, a B flat 57 octaves lower than middle C, which is 256 Hertz. Sounds as low as the black hole singing are detected as pressure waves, rather than as sounds.

According to Dr. Andrew Fabian of the Institute for Astronomy at Cambridge University, this tone, emanating from a black hole in the Perseus cluster of galaxies, is the lowest note in the universe. The note has been traveling toward Earth for 250 million light years.

Dave’s Opinion
What else can I say but “How low can you go?”
