[QUOTE="ohwilleke, post: 6893145, member: 19562"] I think that part of the issue is the focus on the composite boson model, which reads to a casual observer a lot like the Technicolor composite Higgs boson model which fell apart to a great extent when a seemingly fundamental Higgs boson with properties and decays consistent with a Standard Model Higgs boson was discovered starting in 2012 and with each new data release constrained to be more similar to the SM Higgs. Whether this criticism is fair or not as applied to this series of papers is another question. Likewise predictions that were close based upon supersymmetry models and SU(5) unifications gathered less attention because the LHC, direct dark matter detection experiments, and non-detection of proton decay at longer and longer mean lifetimes for a proton, have weakened the most plausible parameters spaces for supersymmetry and SU(5) unifications. In contrast, asymptotic safety gravity didn't have to contend with unfavorable results from collider physics. There isn't much affirmative evidence to single it out relative to other theoretical models in quantum gravity, but there really isn't anything to rule it out either. The focus on the renormalization group evolution in both the work of Shaposhnikov and Wetterich, and in the work of Kahana and Kahana, certainly makes a lot of sense. We can calculate beta function formulas for the top quark and Higgs boson exactly, without knowing exact measured values of the physical constants that need to be plugged in, from the Standard Model. By 1993, we knew lots of the physical constants at satisfactory levels of precision and we had a reasonable ballpark range for the physical constants we knew with less precision, allowing for a much more focused inquiry. We also knew already back in 1993 the theoretical relationship in electroweak theory of the W boson, Z boson, top quark, and Higgs boson masses. Both pairs of scientists were building on this foundation of what was already known to make the final leap into the unknown and conjectural points. Asymptotic gravity and the NJL model also both have solid foundations outside electroweak theory, affording a patina of respectability and plausibility to the leap to use these methods in the basically electroweak sector matters of estimating the Higgs and top masses.
