First up, thanks for the reply el_draco... you have confirmed my new found knowledge that while Black Holes are dangerous, it is unfair to treat them as a "monster" anymore than a giant star (of which there are many more)!

Well, I assume the gravitational field can "escape", as it would be illogical to think that a gravitational field is effected by its own gravity.

Off topic slightly... if we can see Black Holes through 'gravitational lensing', why would we not get the same effect from Dark Matter, which apparently takes up 90% of the universe?!? Surely it would occasionally float between us and a light source?
