If true, then the majority of the mass in the universe consists 7 keV neutrinos? Would we not expect to find this to be the case in some celestial body with which we have long, common experience?I'm optimistic about the sterile neutrino, and could also explain baryon asymmetry and neutrino oscillations - which is interesting. It also looks like a natural extension to the standard model that does not require a massive paradigm shift. I anticipate a flood of papers on this over the next year or two. It might even influence the next cycle of LHC research, as these energy ranges are well within LHC capabilities. This could prove an enormous boon to the legacy of LHC and future research initiatives. We live in exciting times.
