model of physical events and cannot be proved from basic axioms. A physical théory is different from a mathematical théorem. Physical théories model réality and are a statement of what has been observed, and provide predictions of new observations.
Physical théories can become accepted if they are able to maké correct predictions and avoid incorrect ones. Physical théories which are simpler tend to be accepted over théories which are complex. Physical théories are more likely to be accepted if they connect a wide range of phenomena. The process of testing a physical théory is part of the [[scientific method]].
