This blog had noted a rule such as cosmic rays may break. The assumption had been that ambient light imposes a speedlimit upon relativistic protons, 5 × 1019. Since some rays show up with more energy than allowed by this mass and velocity, those rays must not be protonic. Iron ions, for instance.
So here's another rule, which rays of all masses follow. This is an energy limit of 15 tera-electronvolts (trillion 1012; TeV). Implicitly rather a steep dropoff than an absolute limit.
- or "TV", in our article. The Swiss - specifically the Geneva Francophobes - here piggybacked upon a project "meant" for dark-matter. The DAMPE space-telescope. Maybe they just used that name so as to get the funds.
