| The smallest subjects that we have actually detected are the {{w|elementary particles}}. In the {{w|Standard Model}} of particle physics, they are considered point masses (i.e. to have zero width). They may be made of smaller {{w|String theory|strings}} but if so these have still not been detected.

| We think we have a fairly good estimate of how many elementary particles that are known. There could be some uncertainty though, so it is not at the very top.

|Elementary particle physics is concerned with the study of subatomic particles (the smallest things that we know of), of which there are 17, not including antimatter. Most notably, until recently it was uncertain whether the {{w|Higgs boson}} was one of the elementary particles, but scientists have a "pretty good estimate" because the mathematical models don't predict the existence of many other particles.
