Particle physics

Particle physics is the study of how the smallest pieces of matter and energy interact with each other. Particles are like really tiny bits of stuff - so small that you can't see them. There are different types of particles, like protons, electrons, and neutrons, which make up the atoms that everything is made of. Particle physicists try to understand how these particles work together and how they create things like light, electricity, and gravity. They use special machines called particle accelerators to study these particles. By looking at how the particles behave, scientists can gain a better understanding of how our world works.
