Well if we want to simply understand black hole, then consider this example.
Suppose we have a big blanket and it is held horizontally over the ground by four persons holding four corners. Now the blanket is the space-time continuum... remember x,y,z,t from high school.
Now if we put a heavy piece of stone in the centre of it, it will bend the blanket (space-time) around it and perhaps cause a little hump downward on the blanket. Now suppose this stone is of infinite or extremely high mass, so the hump created will be so deep that nothing could go out... this is the black hole...
NB. Stephen Hawking has some problems solving the dilemma of information issue with Hawkings radiation... remember his recent announcement 'I was wrong'. He lost the bet to his colleague John Preskill although he should be credited to come up with now the aparent right answer..
