[Date Answered] August 15, 2008 [Questioner (age, location)] Mary (Tanzania) [Answer] Black Holes are theoretical objects. A black hole is an object which has such high gravitational pull that not even light can escape. Hence it is black. Which makes it pretty hard to observe directly. Black Holes may form as the result of the collapse of a very massive star at its death. More information can be found in our web page Black Holes. [Question] 
what are black holes and what are they made out of???
