Do anyone know anything about Black Hole

yes I have seen Stephen Hawkin's documentary quite a bit and in my college I wrote an article o black hole. very interesting topic and I am really fascinated by the power of black hole in space that it potentially can suck up other stars. This is among my most favorite topic on space.

After a short search on the Internet i found this definition: A black hole is defined to be a region of space-time where escape to the outside universe is impossible. The outer boundary of this region is called the event horizon. Nothing can move from inside the event horizon to the outside, even briefly, due to the extreme gravitational field existing within the region. For the same reason, observers outside the event horizon cannot see any events which may be happening within the event horizon; thus any energy being radiated or events happening within the region are forever unable to be seen or detected from outside. Within the black hole is a singularity, an anomalous place where matter is compressed to the degree that the known laws of physics no longer apply to it.
