It seems astronomers have discovered that black holes emit a single note - Bb (B flat). Which makes me wonder at the Om being emitted by the mantras of the masses. What note is that at? Is it deep in our throats that a Bb is available? The sound I consider happy is not a Bb, but a happier note, like an A or a C. Is Bb the sound of the blues? It would follow, in my random logic, that a black hole and the blues have a common thread.
Of all the notes to be emitted by deep space I am not surprised by Bb. I had hoped for a lighter note, something denoting (pun intended) love or happiness. So then, what note does the sun, or the moon, emit?

The star that exploded in 2004 and 2006 in the far off galaxy 2006 was likely a very massive star like Eta-Carina, of up to 100 solar masses, and doomed to death when its core collapsed to a black hole.
