What is antimatter?
Q: What is antimatter?
A: Antimatter is a material made up of antiparticles with the same mass as particles of ordinary matter but opposite charges and properties.
Q: What is the relationship between particles and antiparticles?
A: Particles and antiparticles have opposite charges and properties, and encounters between them lead to both being destroyed.
Q: What types of particles and energy are produced when a particle and an antiparticle are destroyed?
A: The destruction of a particle and an antiparticle produces high-energy photons (gamma rays), neutrinos, and lower-mass particle-antiparticle pairs.
Q: What is meant by the term lepton number?
A: Lepton number refers to the number of leptons in a particle or antiparticle.
Q: What is meant by the term baryon number?
A: Baryon number refers to the number of baryons in a particle or antiparticle.
Q: How does antimatter differ from ordinary matter?
A: Antimatter is composed of antiparticles, which have the same mass as particles of ordinary matter but opposite charges and properties.
Q: What is the significance of encounters between particles and antiparticles?
A: Encounters between particles and antiparticles result in their mutual destruction and the production of high-energy photons, neutrinos, and lower-mass particle-antiparticle pairs.
