| has definition The view of quantum mechanics holding that a physical system simultaneously exists in all of its possible states prior to and after a measurement of the system. In the many-worlds interpretation, each of these simultaneous existences is part of a separate universe. Every time we make a measurement of a physical system and find it to be in a particular one of its possible states, our universe branches off to one of the universes in which the system is in that particular state at that moment. The system, however, continues to exist in its other possible states, in parallel universes. | |

| quantum mechanics | has applicability microscopic scales of atoms and subnuclear particles but not restricted to this | |
| has constraint certain quantities (e.g. energy, angular momentum, light) can only exist in certain discrete amounts, called quanta. | |
| has implication physical systems must be described in terms of probabilities. | |
| has equation Any physical system, such as an atom, may be viewed as existing as a combination of its possible states, each of which has a certain probability. | |
