Why Are Antiparticles Created?

Antiparticles are formed naturally in space and on the various suns or stars in the Universe as a result of high-energy particle collisions. High-energy cosmic rays from space strike atoms in the atmosphere and create antiparticles. They quickly collide with matter articles and annihilate.

Why do antiparticles exist?

For each basic particle of matter, there exists an antiparticle with the same mass, but the opposite electric charge. ... When a particle and its antiparticle come together, they both disappear, quite literally in a flash, as the annihilation process transforms their mass into energy.

What is the purpose of antimatter?

Antimatter is used in medicine.

These are injected into the bloodstream, where they are naturally broken down, releasing positrons that meet electrons in the body and annihilate. The annihilations produce gamma rays that are used to construct images.
