Every time I get cynical, depressed and in general bored with life around me, science and nature have ways of making me feel like a little girl again :)

In a way, its good that we cant hear it. Imagine not being able to talk to your buddy sitting next to you just because a blackhole is screaming in high pitch some 250 lightyears away..:tongue3:

I had posted on this way back. A black hole cannot emit sound waves or any kind of waves - remember, the gravity is so strong that even light can’t escape it, which is why it’s a black hole! The sound is made by matter just before it crosses the event horizon of the black hole.

So it is the poor matter being sucked down making its last noises - interesting!
