SUMMARY

Proton decay is a theoretical prediction stemming from grand unification theories (GUTs), suggesting that protons may eventually decay into other particles, although no confirmed events have been observed. Current evidence indicates that protons have a lifespan exceeding 10^33 years. In certain radionuclides with a deficiency of neutrons, protons can decay via positron emission, represented by the equation p^+ = n + e^+ + ν_e, where e^+ is the positron and ν_e is the associated neutrino. This decay process occurs within atomic nuclei, influenced by strong nuclear forces.

PREREQUISITES
  • Understanding of grand unification theories (GUTs)
  • Familiarity with particle physics terminology
  • Knowledge of weak force interactions
  • Basic concepts of nuclear structure and forces
NEXT STEPS
  • Research the implications of grand unification theories (GUTs) on particle physics
  • Explore the concept of neutrinos and their role in particle decay
  • Study the differences between positron emission and beta decay
  • Investigate current experimental efforts to detect proton decay
USEFUL FOR

Physicists, students of particle physics, and researchers interested in the fundamental forces and particles of the universe will benefit from this discussion on proton decay.

Kakorot
Do proton's decay?
and if so, what do they turn into?
and can they decay when they are in a nucleus?
I read a theory on how the universe will end up being a sea of electrons, and what protons become when they decay.

Proton decay is a prediction of certain grand unification theories [GUT's]. No confirmed events have been detected and evidence to date indicates a lifespan of greater than 10E33 years... a very long time. See here for more details:

In some radionuclides with a difficiency of neutrons, a proton will decay by positron emission (weak force) according to:

p^+ = n + e^+ +\nu_e, where e^ is the positron and \nu_e is an electron-associated neutrino. Note that it is a neutrino and not an anti-neutrino as in beta-decay. Also, this is in an atomic nucleus where the protons and neutrons are affected by the strong nuclear forces.
