Also, what is einstein's general theory of relativity and how does it account for the blackness of black holes?

Newton: every action has an equal but opposite reaction.
Black holes: the gravity is so powerful that it sucks in everything, like a giant vacuum cleaner. That is EVERYTHING, including light.

It recoils due to one of Newton's laws. With every action, there is an equal and opposite reaction. The action is water being forced out of the hose at high pressure. The reaction is the water pushing on the hose with an equal force. The same concept can be used to explain how a spaceship is propelled.
About the black holes, I believe it is due to the warping of 3D space itself due to gravity. This explains why star light is bent when the sun passes between it and the earth. Not too sure if that is the answer you are looking for.

A hose recoils because any action has an equal and opposite reaction. The action in the hose example is the pressure in the hose pushing water out. That action has an opposite reaction which is the hose pushing back in the opposite direction of the water.
