Several questions still remain unresolved with respect to the standard model:
- Why are there three pairs of quarks when it appears that only one pair is needed to make matter?
- What gives particles (also atoms and matter) mass?
- Why is the top quark (which is 35 times bigger than the bottom quark) so massive compared to the others?
These are but a few questions that are being pursued in the world of particle physics.
