What happen when something enter the black hole?

12 December 2014 0 5K Report

Is all the materials remain in the black hole or it come out from it by some hidden dimension? Why there is relationship between mass of black hole and mass of associated galaxy? Why there is feedback? Can we propose that material fall in black hole spread on associated galaxy and therefore make feedback? Some kind of big wormhole. I am naive to this field and need more detail.
