If asymptotic safety is right — and it’s looking like the Standard Model might be stable up to energies far beyond the reach of accelerators the size of the entire Earth — there might not be anything at all accessible to humanity as far as experimental particle physics is concerned. And a Higgs mass of 126 GeV might be just the thing to seal that deal.
