Has these results been extended to non-extremel BH? Do they work when the cc is +, (deSitter) and where SUSY is strongly broken (like our world) Do they work when the background is strongly varying in time, such as two black holes merging? They work for extremel black holes that are rotating, rapidly losing or gaining mass or charge? i.e if they calculate using string theory an extremel black hole entropy, what happens to the entropy as the bh becomes more neutral charge? Does it offer precise details of hawking radiation, its spectrum and particle content? Roger Penrose in Road to Reality and Lee Smolin in TWOP expressed deep skepticism of string theory's derivation of black hole entropy. "I am quite unconvinced" Penrose states plainly in RTR. Are there any reasons to be skeptical of this deviation? i.e are a pile of branes really a black hole? is it true they make these calculations with gravity = 0 and no cosmological constant? What is the physical interpretation of these results? The microstates are branes? Is the entropy volume-extensive? What are some qualitative physics in the interior beyond event horizon when GR and QM break down.
