Fundamental Particles and Forces in the Standard Model of Physics

The video explores the fundamental particles that make up matter, as described by the Standard Model. It begins with the concept of breaking down objects to their smallest components, leading to the discovery of fundamental particles like electrons, protons, and neutrons. The video explains how these particles interact through forces such as electromagnetism and the strong force. It also covers high-energy particles, the weak force, and the role of particle accelerators. Neutrinos and antimatter are discussed, along with the Higgs boson and ongoing mysteries in physics, such as dark matter and gravity.
