Question

Aren't black holes required to exist forever in our frame of reference?

Answer 1

Here is your answer.....
I know that for an observer far away, nothing ever crosses a black hole horizon (due to time dilation), while in the frame of reference of a falling observer the horizon is nothing special on its way in; and there is no contradiction because in the far away frame of reference the horizon is reached in the infinite future. Now considering that a black hole evaporates in a finite time, it cannot exist in the infinite future of a far away observer. So it seems there is a contradiction here, where the observers (free-falling and far-away) do not agree on the mere fact that the horizon is reached at all by anything during the whole black hole lifetime. Thus my question: by the very nature of their topology in spacetime, aren't black holes required to live forever in our frame of reference ? Think about it....

Answer 2

The "information loss paradox" in black holes—a problem that has plagued physics for nearly 40 years—may not exist.
