What is antimatter?
Antimatter consists of antiparticles corresponding to ordinary particles but with some opposite quantum properties.
How it works and what the evidence shows
Core idea A positron is the electron’s antiparticle and has positive charge. When particle and antiparticle meet, annihilation can transfer their energy into other particles. Evidence and research Laboratories produce antiparticles and confine tiny amounts in electromagnetic traps. Measurements test symmetries between matter and antimatter.
Uses and limitations
Why it matters Why the observable universe contains so much matter remains under study. Antimatter experiments probe fundamental laws and the early universe. Common misunderstandings Antimatter is not a limitless practical energy source. Producing and storing it is extremely difficult and available amounts are far too small for fictional uses.
