Actually, that would be a great question for a physicist to resolve.
Next question: would a permanent magnet make any difference?
I admit I changed my thought experiment at the last minute to use a
magnet instead of a charge because I could more realistically imagine a
powerful magnet and a simple detector. That may have been a mistake.
A charge, however, would do the "floating" I presume. It's difficult to
find a straight answer online. The topic of a charge falling into a
black hole is addressed from one angle at:
This is from an answer by a guy who says he's got a PhD in general
there's no problem with information falling IN to a black hole, which
is allowed to externally display it's mass, charge, angular momentum
and linear momentum, all of which get inprinted on the horizon as
matter falls in
Again, I'd like a physicist to give a straight answer.
