An acquaintance raised a question, and we disagree on the answer. I'm
hoping to break the tie and understand if I'm wrong. Hope you guys can
help! Here's a brief summary:
Jack is 'near' the event horizon. Let's say that from his pov it will take
a year to pass that horizon (moving 'slowly'; as the gravitational effect
on time is the issue).
Jane is further away and stationary, but close enough that the time delay
for light travel is inconsequential. In HER timeline it takes, let's say,
two years to see Jack cross the event horizon.
The black hole evaporates at the 1.5 year mark in Jill's timeline.
The question boils down to: Where is Jack?
My feeling is that Jack is 3 months from the previous event horizon. His
is that this is a paradox because, according to Jack's timeline, he OUGHT
to have passed the event horizon.
For all I know, this is a well-known topic of discussion, but not for me.
I appreciate any illumination that is forthcoming (and it would certainly
be nice if everyone was in agreement!).
