I have also been studying about black holes the outside of the black hole is called the event horizon if you get sucked into the event horizon you can’t get back even light can’t escape. If you’ve seen a picture of a black hole I think you would of seen to beam’s of light coming out of the black hole. Well those beam’s aren’t light they are beam’s of radiation the radiation has a name it is called Hawking Radiation when two particles join tougher they eliminate each other. Then they reappear but if if there is a black hole near then one of the partners gets sucked the black hole and the other partner goes to find another partners creating the beam of light.
