Q: Black Hole Horizon

25-AUG-2007

Hi all -

Assuming, for the sake of simplicity, a non-rotating BH, it's been
conjectured that for an external observer the "image" of any matter
falling through the critical circumference is (forever) frozen at the
horizon. Two questions:

1. Doesn't this essentially preserve (some) information about the
infalling matter, for any external observer, and

2. Doesn't this endow the BH with hair?

The idea seems to suggest that any BH that has ingested matter would
have a horizon forever postered with the images of these hapless bits,
for any passing observer to see. How then would the black hole remain
dark to the outside universe?

cheers,
