Light can't escape from within a black hole, but information can. Two pieces of information escape from a black hole - its mass and angular momentum. The mass can be found from the strength of its gravitational field. As I remember (from a physics lecture) the angular momentum can be found by sending a satellite around the black hole. The satellite will return rotated as I recall, though I don't really understand why. It probably has something to do with the curvature of space around the black hole. It would seem that information transmission is not necessarily bound by the properties of light. Any comments? Arch - uiucdcs
