the antimatter

Antimatter is in some invisible characteristics the opposite of ordinary matter. Antimatter is made up of antiparticles just like ordinary matter is made up of ordinary particles. Antimatter looks and acts just like ordinary matter, but if an ordinary particle and its antiparticle meet then they both turn into energy (according to the famous equation of Einstein (E = mc^2)), and energy can be turned into pairs of an ordinary particle and the corresponding antiparticle.
