thread about two weeks ago, but apparently it got lost in cyberspace.
My question is: What is the current status of the black hole
information loss controversy?
The physics FAQ on the subject says it was written by Warren Anderson
in 1996. A whole lot of water has gone over the dam since then.
Perhaps it needs to be updated.
What -is- the current thinking of the major groups of players?
First, what do the string theory people think?
I know at least some string theorists think that the black hole
information loss (bhil) question has been resolved in favor of no
information loss (eg Mathur et al) (See recent press release saying
that Hawking and Thorne should pay off their "famous bet" with
Preskill, which made it into USA Today and Economist, but not NY Times
at least as far as I could tell.)
Do string theorists in general agree with this? And also, do they
agree in general with the Mathur et al approach?
Second, what about Loop Quantum Gravity People? Are they mostly of
one mind re bhil, or do they differ? My gut feel is that they are
in, or lean toward the no loss camp, but I am not sure.
Does bhil show up anywhere in the recent 125 page Ashtekar-Lewandowski
review? I haven't read it all, but I found references to elimination
of singularities and eliminanations of BKL chaos, but not a direct
reference to bhil. (Does elimination of singularities imply
elimination of bhil, or must you also eliminate horizons, or mitigate
them in some way?)
Finally what about the type of people who are not into ST or LQG, but
work on things like Gravity Probe B, LIGO, LISA and all the similar
experiments?
Do they even care about bhil, and if so, in which direction do they
lean?
So how about it?
Should Hawking and Thorne pay off Preskill, or does this debate still
have a long way to go?
I am very curious to hear what the experts think.
TIA. Jim Graber
