It is somewhat vague question. I have BSc in physics and took a general relativity course some years ago. But this issue was never clear to me - I am not looking for a formal explanation but just an outline of what the answer to my question might look like.
And here is the question: I occasionally hear people referring to a thought experiment where someone falls into a black hole, usually accompanied by the assumption that black hole is large enough so that the tidal forces are not strong at the horizon. What I do not understand is what, say, happens with the electromagnetic field in a situation where one part of the body is already crossed into the horizon while the other part is still outside. Seems that the outside part has no way to interact with the inside part (except gravity) does this imply that the material disintegrates in some sense? Regardless of the tidal forces?
