I think it is out of line to pester Carlo Rovelli with one's own specious arguments and put words in his mouth. Carlo has not "conceded" or "admitted" anything remotely like "LQG is wrong" as one of our members claims. The poster has an argument, to which I doubt Carlo would subscribe and which I believe is groundless, for why one should say "LQG is wrong". The argument depends on LQG being perceived as extremely rigid---dependent on one unique version of General Relativity. I know of no indication that LQG is, in fact, unable to accomodate higher-order terms in the Einstein-Hilbert action, or other slight modifications in General Relativity noticeable only at very high energies or small scale. Indeed LQG is clearly not inflexible since Loop researchers already modify the dynamics. This is most evident in LQG cosmology where sufficient progress has been made recently (more than in the full theory) that there is well-behaved dynamics to play around with and try variations on. Anyway the poster's argument seems to be that LQG is wrong because it can work only with one fixed version of Gen Rel, and that because one of the concepts of LQG (spin networks, a way of constructing a basis of a certain Hilbert space) is meaningless save when GR is JUST SO. This sounds quite far-fetched. In any case it is not what Rovelli says. So my reaction is let's not put words in Rovelli's mouth Theory wrong or theory right is not my concern here. If you want to make a big deal of it Einstein's GR was "wrong" in the sense that if you push it to far you run up against singularities where it won't compute. Maybe LQG will have its own different but analogous limitations. But since it is a flexible and adaptible theory still under development, I dont think anyone today is smart enough to say what the limits of applicability will be. Instead, what I object to is two things: 1. Rovelli's time is valuable, why bug him with chaff? 2. Why misrepresent him as saying what he didnt say (not even "in effect" as the latest version puts it)? That doesnt seem right.
