particles and antiparticles

Particles are the fundamental building blocks of matter, like electrons and quarks, which make up everything around us. Antiparticles are their mirror counterparts with the same mass but opposite electric charge and quantum properties. When a particle meets its antiparticle, they annihilate each other, releasing energy. For example, an electron’s antiparticle is the positron. This process is central to understanding fundamental physics and is used in technologies like PET scans. Antiparticles are rare naturally but can be generated in laboratories. Their study helps scientists explore the universe’s origins and the fundamental symmetry of nature.
