this just out
L. Modesto, basically following Bojowald's program
and a variant of it started by Husain and Winkler
says he has gotten rid of the Black Hole Singularity
by quantizing the spacetime model
http://arxiv.org/gr-qc/0407097
this is what Bojowald did with the Big Bang singularity
(it has always been expected that when there was a successful
quantum theory of gravity----that is, a quantization of Gen Rel---
that it would get rid of GR singularities and extend on past them.
I thought Bojowald was preparing to address the BH singularity
because of a couple of preparatory papers he just posted that
were in that direction.
I am surprised that Modesto has apparently gotten to the goal
first. But it is only an 8-page paper and there is surely a lot more
to be done in ironing out the BH singularity in all possible cases and
seeing what is beyond it!
Modesto is at Rovelli's Marseille University Institute of Theoretical Physics.
I expect that Rovelli may be advising Modesto, who AFAIK is new.
There are a bunch of new authors in LQG and allied research areas.
the Husain and Winkler paper that Modesto uses to some extent as a guide is one that Olias flagged for us here at PF:
"On singularity resolution in quantum gravity"
