If the bodies fall under the horizon, the information about them perturbs the horizon itself, and though outside observers cannot reach the bodies which have fallen under the horizon, they can still measure the properties of the perturbed horizon. | |
| Apr 6, 2012 at 16:06 | comment | added | John | Oh, ok so if the data is permenantly stuck inside the event horizon, the it's considered "destroyed"? And "information" cannot be created or destroyed, right? Is that the idea? | |
| Apr 6, 2012 at 12:06 | comment | added | Alexey Bobrick | Sorry for downvoting, but I can't agree with the answer. In classical theories point particles also generate singular potentials, but all the conservation laws hold. In GR, if you have an asymptotically flat space (with a black hole) you can still comfortably enough introduce conservation laws. The real problem with information comes from the fact, that the objects can only enter, but not leave the event horizon. | |
| Apr 6, 2012 at 5:09 | comment | added | Ron Maimon | -1: This answer is incorrect. I am sorry to downvote, but a singularity is not a "point of infinity", but a point of infinite curvature, and even then, it is not so terrible by itself. The singularity is not the issue with this stuff, it is all exterior things that are the issue. | |
