| Antiparticle Story1 #722585 The theory describing the infinitely small states that each particle is associated with a "mirror" particle, called antiparticle. This has been confirmed by experiments. A particle and its antiparticle share many properties. In particular, they have the same mass but have opposite charges. If enough energy is available, particle-antiparticle pairs can be produced. But the antiparticle will annihilate if it crosses matter. |
