If my twin were to be in a Schwarzschild black hole, and have passed the event horizon, I would see him as passing the horizon in infinite time. But, what would he see? How would I appear to him? Would my twin ever know that he is in a black hole? If my twin shines a torchlight towards me, who is outside the black hole, would the light travel to me, ie escape the horizon? If not, what would happen to the light photon?
