| '''Annihilation''' is defined as "total destruction" or "complete obliteration" of an object; having its [[root]] in the [[Latin]] nihil (nothing). A [[literal]] [[translation]] is "to make into nothing". | | '''Annihilation''' is defined as "total destruction" or "complete obliteration" of an object; having its [[root]] in the [[Latin]] nihil (nothing).

− | In [[physics]], the [[word]] is used to denote the [[process]] that occurs when a [http://en.wikipedia.org/wiki/Subatomic_particle subatomic particle] collides with its respective [http://en.wikipedia.org/wiki/Antiparticle antiparticle]. Since [[energy]] and [[momentum]] must be conserved, the [[particles]] are not actually made into nothing, but rather into new particles. Antiparticles have exactly opposite additive [http://en.wikipedia.org/wiki/Quantum_number quantum numbers] from particles, so the sums of all quantum numbers of the [[original]] pair are zero. Hence, any set of particles may be produced whose total quantum numbers are also zero as long as conservation of energy and conservation of momentum are obeyed. | + | In [[physics]], the [[word]] is used to denote the [[process]] that occurs when a [https://en.wikipedia.org/wiki/Subatomic_particle subatomic particle] collides with its respective [https://en.wikipedia.org/wiki/Antiparticle antiparticle].
