Browsing: Antiparticles

Antiparticles are subatomic particles that are counterparts to the particles that make up regular matter, but with opposite electrical charge or other quantum properties. For every fundamental particle, such as an electron, proton, or neutron, there exists a corresponding antiparticle. For example, the antiparticle of the electron is called the positron, which has the same mass as an electron but a positive charge. When a particle meets its antiparticle, they annihilate each other, releasing energy in the form of photons (light) or other particles. Antiparticles play a crucial role in particle physics and are key to understanding the symmetry and fundamental forces of the universe. While antimatter is rare in the observable universe, it is actively studied in laboratories and plays a role in medical imaging techniques like positron emission tomography (PET). Understanding antiparticles could provide insights into the origin of the universe and the imbalance between matter and antimatter.
