Antimatter consists of particles that are counterparts to the particles of ordinary matter, but with opposite charge and quantum properties. When antimatter meets matter, they annihilate each other, releasing energy.
5 Must Know Facts For Your Next Test
Antiparticles have the same mass as their corresponding particles but opposite charges; for example, the positron is the antiparticle of the electron.
Antimatter can be produced in high-energy processes such as cosmic ray interactions or particle accelerators.
When a particle and its corresponding antiparticle collide, they annihilate to produce photons or other particle-antiparticle pairs.
The existence of antimatter was first theorized by Paul Dirac in 1928 and confirmed experimentally in 1932 with the discovery of the positron by Carl Anderson.
Conservation laws, such as conservation of charge and conservation of baryon number, apply to reactions involving antimatter just as they do for matter.
