So I was listening to a book by Leonard Susskind and he was explaining what it would be like crossing the event horizon of a black hole from two different reference frames. In the first, if you were actually crossing the event horizon you would feel nothing as it is just some mathematical boundary in space. But someone from another perspective just outside of the horizon will watch you fall into it but then what does he see? He sees an image of you? Is the image the "information" in electromagnetic radiation? The image must go away because inside the event horizon things blueshift? How can an outside observer see you if the event horizon marks the point of no return? How does something escape it? Are my definitions incorrect?
