Standard model since 1970s correctly predicted Quarks, force particles and higgs boson (13 years ago). But not explained are gravity, dark energy or dark matter, the muon g minus 2 (last year), right-handed nutrinos. Search for super symmetry continues.
The standard model considered good but that we will need a new model because there are too many unanswered questions, or, according to others, just needs to be modified slightly.
