What is Proton decay?
<!-- {{complex}} The idea which describes the strong, weak and electromagnetic fundamental forces states that [[Proton | protons]] are stable, i.e., that the laws of physics do not allow a [[Proton | proton]] to decay, without external cause, into an antimatter counterpart of the electron and photons because of conservation of the baryon number. However, it has recently been suggested that the greater amount of matter over antimatter in the universe is the result of a very slight imbalance in the ratio that occurred very early in its formation. --> '''Proton decay''' is a [[theory]] that a [[proton]] could decay into two small [[particle]]s, a [[pion]] and a [[positron]]. This would be a new type of [[radioactive decay]]. So far, proton decay has not been observed, but some [[physicist]]s believe it. Most current theories say that protons do not decay. {{physics-stub}} [[Category:Nuclear physics]]
