deleted "tested" because next paragraph contradicts this!
<ref>"A theory not only explains known facts; it also allows scientists to make predictions of what they should observe if a [[theory]] is true. Scientific theories are testable. New evidence should be compatible with a theory. If it isn't, the theory is refined or rejected." [http://www.amnh.org/exhibitions/darwin/evolution/theory.php] </ref>

Generally accepted scientific theories have been tested and survived over time, have evolved when appropriate, and modified toward consistency with newly discovered data, have not been shown to be false and can make predictions about natural phenomena. <ref>http://www.thefreedictionary.com/theory </ref> Scientific theories can sometimes be used as the basis for industrial and technical developments.

A scientific theory does not necessarily have to have strong experimental support or accepted by the scientific community. Scientists often refer to untested theories and competing theories. Theories can be extremely well-confirmed, such as conservation of energy, or speculative, such as [[String Theory]].
