Ilja Schmelzer, the author of
http://arxiv.org/gr-qc/0205035
just introduced himself in one of the Philosophy Forums.
I am guessing he is a new member of PF
so I personally wish to welcome him and
provide an opportunity for anyone who is
interested in alternative approaches to
quantizing gravity (besides Loop Quantum Gravity and String)
to ask Ilja questions.
It is often said that besides LQG and String
there are other quantum gravity attempts like
"condensed matter models" and Alain Connes "noncommutative geometry".
LQG and String are simply the two main ones.
However recently in the arxiv's section called "gr-qc"
(General Relativity and Quantum Cosmology)
I have noticed numerous "condensed matter" papers, indicating
that it is an active line of research to try modeling
gravity by using solid state physics methods. Although
I know nothing about this, I suppose it must mean having a preferred frame of reference
and an "aether" giving a kind of substantial existence to
space. I was under the impression that observation evidence
had ruled that out! Nevertheless "solid state" approaches to
gravity are being developed.
And someone who has written a paper in this line of research
has appeared here. Ilja's paper is titled:
"A generalization of the Lorentz ether to gravity with general-relativistic limit"
here's a link to the thread in Philosophy section
