The Perseus galaxy cluster is seen in two different images taken over a 53 hour period by the Chandra X-Ray Telescope. The central region of the galaxy is seen at left while wavelike features (right) that appear to be sound waves are seen using a special image-processing technique to bring out subtle changes in brightness. Sound emanating from a black hole within the cluster appears to have a pitch about 57 octaves below middle C, far deeper than humans can hear. Andrew Fabian of the Institute of Astronomy at Cambridge, England believes the sound is the deepest note ever detected in the universe. (Reuters)

Date: 2003-09-09 11:29 pm (UTC)That's a strange thought.
Date: 2003-09-10 10:50 am (UTC)Sound is exponential, as is light. That means that C4 is half the frequency of C5 is half the frequency of C6.
That would mean that the sound would be like .000000000000000000000000000000000000000001 hz or something like that. I can't fathom....
It's beyond me. That's a HUGE sound wave. Consider it's amplitude. If you were in a solid air tight room (with air, and atmosphere), that soundwave would probably mutilate you from the db - compress you until you exploded. And also blow the room up. Everything would just...... KABOOOOOOOM.
You'd need a big frigging woofer to recreate that ;-)
It would sweep out from there.
