Hey, I saw some things on here which aren't entirely correct, I just wanna set the record straight.... no evil intentions or attempt to anger anyone is being made.
1)Nothing is seen past the event horizon of a black hole. Beyond that, there are great masses of rotating gasses becoming enormously compressed orbiting their way around and falling in towards the black hole. These massively compressed gasses, dust, etc. get so incredibly hot that unfathomable amounts of energy are released well outside the event horizon. This energy can escape and be seen.
-> Once something (gas, dust, small planets, etc) has passed the event horizon you will see nothing from it. The idea of the event Horizon is that at that point the escape velocity is the speed of light. As matter cannot reach this (thank Einstein) once it passes, it's gone. this also works for light, the speed of light is constant, once it passes the event horizon, it ain't coming back either. what we see from Chandra is photons(X-rays) that have been released PRIOR to some chunk of mass passing the event horizon.
2)Does anybody here know about the work that is being done on gravity waves?
-> try checking out LIGO (Gravity wave observatory just now coming online)
http://www.ligo.caltech.edu/
3)I assume its not particuarly dense just particuarly big.
-> Black holes are by nature very dense. They have vary large amounts of mass stuffed into very small areas. For instance a small blackhole usually consists of several times the mass of the sun stuffed into an area of roughly the size of New York city.
4)is it 'draining' clockwise or counter-clockwise?
-> depends from which side of the galaxy you look at it...from above or below?;)

thank you, I try to be metaphysical at least once a day :)
In all honesty, why was this posted? shua it's neat, but what's there to discuss?
FP?
peoples, you're making a slight error in your statements.
Browser of choice = your top choice of what you want to work in.
Browser of necessity = what you're forced to work with even if you don't want to.
slight difference, but it is an important one.

Unless George W. Bush cloned himself 67 times and got those clones elected
to the Senate
Oh god the horror, oh thanks a bunch! now I'm gonna have nightmares for weeks!
