I see your point. Virtual particle production occurs microscopically close to the EH. Events there should be stretched out over the age of the universe as observed by a distant observer.? said:Could you clarify how long it would take for this to happen? In other words, I think I am reading that all the posters on this thread agree that to the outside universe, time goes very slowly (maybe even stops) at the EH. This applies to this falling towards the BH, so I assume it applies to things going out again. So the rest of the universe is sitting on our hovering spaceships and watching the Hawking radiation coming out past the EH. But how does it get out? The rest of the universe is long gone by the time this radiation manages the trip.
It's the same argument as things falling into the BH. Sure, the proper time on the falling object proceeds at the normal rate (whatever that is). But the rest of the universe outside the EH has lived out it's lifetime and no longer exists by the time the falling observer crosses the EH. All of the Hawking radiation will be frozen at the EH going the other way, just as all of the falling objects will be frozen at the EH. The BH will never lose any mass, as view by those of us who are in the rest of the universe, it will only exponentially gain mass until it consumes everything.
It's part right and part wrong.
EM travels at the speed of light, so it will always climb out of the gravity well at a speed of c, so no weirdness there. But what the time dilation does do though is red-shift the EM. Essentially Hawking radiation will be red-shifted to virtually zero.
