Main Question or Discussion Point
Is it possible to unify both theories ? I think it may be possible
Smolin is another one that worked hard on these matters. A few years ago he gave a long list of such papers:It is not obvious why one would WANT to "unify LQG with SMT". One might lose valuable/interesting features of both. So it makes sense, when reading the papers, to look for each author's stated motivation---what they hope to achieve.
