Elementary Particle

An elementary particle is the smallest possible element of the Universe. It is not composed of other objects. It cannot be divided or broken in two.

When a particle appears, it is never alone. At the same time as it appears, a particle of opposite charge appears, for example a Positron. On the other hand, some particles are themselves their own antiparticle, for example Photons are also antiphotons. This is the Antimatter.

Properties

• One cannot say at the same time where an elementary particle is and where it goes: Heisenberg Uncertainty Principle.
• They can jump: Quantum Jump.
• They take all paths, possible or not, imaginable or not, as soon as no one observes them.
