Hi, I was wondering if anyone who really understands black hole complementarity can answer some questions for me. I understand what happens from the view point of the observer outside a very large black hole. But I'm concerned with the view point of the in falling observer. In particular does the black hole evaporate according to her? If not this suggests that the black holes mass will never decrease. In the many worlds interpretation of QM it seems to suggest that by crossing the horizon she actually moves into a different spacetime history than the one observed by the observer outside the black hole? This seems to be the only viable option once you take the backreaction of the Hawking radiation into account? This all suggests that when is comes to the quantum mechanics of black holes we can preform an experiment with two different observers and the expected result for each observer will be very different. So do we need to modify the principles of standard QM in any way to accommodate for black holes?? Thanks, Finbar.
