Two guys at CalTech and Jet Propulsion Lab just posted
http://arxiv.org/gr-qc/0407090
which appears to take care of the BH information paradox
by analyzing how particles just about to disappear across the
event horizon can signal their essential information as they fall in
(a swan song, his entire life flashed before his eyes...)
so while Hawking says the info falls into the hole but is not destroyed and eventually (in a way he did not specify) percolates out
these people explicitly say that once particles fall into the hole they become indistinguishable and all informtion (except name rank serial number) is lost (sorry, except for mass, spin, and charge)
so they contradict Hawking's resolution of the paradox
and resolve it in their own comparatively concrete reasonable fashion
Black holes conserve information in curved-space quantum field theory
Christoph Adami, Greg L. Ver Steeg
4 pages, 2 figures
selfAdjoint has remarked on the strange coincidence that within the short space of a couple of months we see a handful of different resolutions of
this paradox----all incidentally contradicting each other
Personally I'm partial to Gambini Porto Pullin which uses a realistic material clock to define time---eschewing idealized time
but there is also Hawking
and these people: Adami/Ver Steeg
and who else did we hear about?
