This may seem like a naive question to some people. I had always heard that Lqg can easily incorporate supersymmetry---that if there were any evidence of it, putting it into the theory would be straightforward. This goes way back, to papers I read in 2003-2005. Not sure exactly which, but it was a "well known" commonly accepted truth. There was a similar statement about Lqg in higher dimensions that I think I recall seeing in a paper by Lee Smolin, but I don't know how widely accepted that was. Anyway Carlo Rovelli recently remarked that the failure to see signs of Susy at LHC was GOOD NEWS for Lqg. I think that means that simply means that a Susy signal would have been bad news. So we can be happen one has not been seen so far. http://twitter.com/#!/carlorovelli/status/107757207243862016 The question is WHY? At first I thought this must mean that the recently (2007-2010) developed new formulation of Loop Gravity presented some obstacle to supersymmetry, at least at some level. So then obviously seeing Susy could be a setback for the program. But I have not gotten any indication that this is right. So I must retract on that! Apparently if there were some indication that nature is supersymmetric the Loop program could make a smooth transition. This was what Lee Smolin's recent post here would seem to imply. Not a serious setback at all. However then why would a Susy signal at LHC have been bad news for the Loop program?
