What in of black hole?

Nobody knows. It's a mystery. Because no one has ever entered a black hole and returned. The theory is that it leads to another dimention which you cannot return from. So if you have a good life here on earth, stay out of the black hole. If you have a lousy life and no one to care for and no one cares for you anyway, go into the black hole. Maybe you'll find a better life wherever that leads. Good Luck.
