Say for instance me and another person were 1 light hour away from each other. Now at my position I am subjected to a much greater gravitational field and thus, due to time dilation, 1 hour for me is 2 hours for him (at his current position). If I were to send a beam of photons at him, relativity dictates that the light would reach him in exactly 1 hour for both our frame of references. But, now there is a problem in that 1 hour for me is 2 hours for him. So if he saw the light after his stopwatch hit 1 hour, only half an hour would have passed for me. And if I stopped my stopwatch at 1 hour exactly when the light had reached him, 2 hours would have passed for him (and that is when he would stop his stopwatch - but this can't be possible since the light would ALWAYS reach him in 1 hour). Maybe I'm just being stupid and forgetting something here. And I'm sorry if I am asking a noob question in a forum filled with intellectual threads discussing deep advanced equations. But this question has been bugging me for quite some time.
