I know this is a duplicate question but the other answers didn't explain clearly my problem. The talkes about no hair theory for explaining the communication and information problem of matter inside the black hole. But I just want to know how it is possible that a field can escape from a black hole. It is not clear where an electric field is made of and perhaps that is the lack of information which can answer why it can escape a black hole.
