Here's the link without the extra http: http://news.bbc.co.uk/2/hi/science/nature/3096776.stmWow, that's cool! Thanks, eta. Sound waves spreading out from the cavities could provide the much sought after heating mechanism. Is that really so? That sound waves can carry heat; or maybe generate it? Can there be friction in space?

That *is* interesting. I know nothing about music, so no comments please if this is a ridiculous question...If you can't hear a B flat like that, can you feel it.

From the BBC article:
The black hole lives in the Perseus cluster of galaxies, located 250 million light-years away.
Like I keep saying, look it up in Perseus.

well, think about the lowest note you ever heard, maybe a truck going by, or an earthquake. this is so many times lower it's bassically(!) incomprehensible. and it's been playing for 2.5 billion years(I think they mean 9 zeros...  ) you wouldn't feel this note, I would think; the waves are too big. you are inconsequential to them. awesome. Jackie, thanks for the link fix; I hadn't noticed my error. and as for the heat, somebody smarter than me will have to explain that one.

Cosmic FoghornOkay, we've got the *name of the group, now all we need is a few players. Lessee...Pfranz definitely fits into this one...bass, lead, or rhythm, Cap?  And don't all you keyboardists raise your hands at once. With a name like that we have to build on the foundation once created by Yes, The Moody Blues, Genesis, Jethro Tull...and, oh, okay... Pink Floyd...and, I guess, a little psychedelia, too, ala Uriah Heep...and go from there. Eta, looks like you're the producer.
