Introduction to Standard Model
In particle physics, the Standard Model (English: Standard Model, SM) is a set of theories that describe the three basic forces of strong, weak, and electromagnetic forces and the basic particles that make up all matter. It belongs to the category of quantum field theory and is compatible with quantum mechanics and special relativity. So far, the results of almost all experiments on the above three forces are in line with the predictions of this theory. But the standard model is not a universal theory, mainly because it does not describe gravity.
