Pump up the bass!

NASA announced today that it has detected a sound wave — a pressure wave to be exact — emitted from a black hole deep in space. The figures associated with this finding are astounding.

First, the black hole is in the Perseus galaxy cluster, which is 250 million light years away.

The frequency of the wave is B flat, but 57 octaves lower than a normal B flat played at middle C on a piano. Or, a million billion times lower than the human ear can detect on its own.

NASA has also calculated how long the sound has been playing. You ready for this? 3 billion years! That's got John Cage's Organ²/ASLSP composition beat by a long shot.
