I read that light can orbit a black hole just outside the event horizon. Is this true?
If it is true and light orbits for a long enough time, would you be able to look behind you and see yourself in the past?
Cool, thanks.So another thought along those line, if I were (in this situation) to shine two lasers parallel to each other, they would continue around black hole (around the event horizon) and return back to me still parallel?
