i'm getting quite confused about this antimatter stuff. ive heard that for every particle there is a corresponding antiparticle somewhere out there in the universe. but it also said somewhere else about the big bang theory, that the universe only exists because for some unexplained reason there is far more matter than antimatter. which one is correct? and what is antimatter? i think of particles and matter as blobs, so is an antiparticle also a blob? i read some analogy to explain antimatter as thinking of a sheet of metal and stamping circles out of it. the circles are matter. The spaces left in the sheet of metal are antimatter. but that doesnt really make sense. If anyone can help clarify all this stuff than thank you very much.
