In a couple of recent threads, I have attempted, unsuccessfully, to elicit a response to the following, which is my belief about why an observer standing well off from a black hole will in fact see the black hole evaporate (over a LONG period of time, of course, so the observer has to have an unrealistic lifespan, but that's not the point).
My logic is this: assuming Hawking Radiation is real then in the far far future the black hole will evaporate down to nothing. As it finishes evaporating, the view seen by the incredibly long-lived observer will change from not seeing anything falling into the event horizon, to seeing it because the event horizon will shrink to nothing as the BH evaporates, and the photons showing the in-falling object actually falling in will be released.
SO ... I contend that an observer WILL see a black hole evaporate, he just has to wait a while. QUITE a while. And so the oft-heard statement that an observer will never see anything fall into the black hole seems wrong to me.
Comments?
P.S. I have no idea whether this thread should be "I" or "A" but the forum requires a choice so I flipped a coin.
