The Standard Model is a theoretical framework in particle physics that describes the fundamental particles and forces that govern the universe. It includes particles like quarks, leptons, and bosons, which interact through the electromagnetic, weak, and strong forces, while gravity is not included in this model. Developed throughout the 20th century, the Standard Model has been confirmed by numerous experiments, including those conducted at the Large Hadron Collider. Despite its success, it does not explain everything, such as dark matter and gravity, leading physicists to seek a more comprehensive theory.
