the prediction of the Big Bang and the cosmic microwave background,.the prediction of electroweak unification and the Higgs boson,.
the structure of the Standard Model, with the strong nuclear force, the weak nuclear force, and the electromagnetic force,.the prediction of additional “generations” of both quarks and leptons,.the prediction of quarks as constituents of the proton and neutron,.the prediction of the neutrino: a subatomic, energy-and-momentum-carrying particle participating in nuclear reactions,.the prediction of positrons: the antimatter counterpart of electrons,.While experiments and observations have revealed a number of hitherto unsolved puzzles - puzzles like dark matter, dark energy, cosmic inflation, baryogenesis, massive neutrinos, the strong CP problem, and numerous others - theorists have failed to make significant progress on all of these issues over the past 25+ years.
Higgs boson mass how to#
We figured out what the fundamental forces and interactions governing physics were, what the fundamental constituents of matter were, how they assembled to form the world we observe and inhabit, and how to predict what the results of any experiment performed with those quanta would be.Ĭombined, the Standard Model of elementary particles and the standard model of cosmology represent the culmination of 20th century physics. After all, the 20th century was a century of theoretical triumphs: we were able, on both subatomic and cosmic scales, to at last make sense of the Universe that surrounded and comprised us. Is all of modern theoretical physics pointless? If you listen to a disillusioned high-energy physicist, you might conclude that it is.
