This means that there must be some way to do experiments that could counter the theory's predictions, thus disproving the current theory.

<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.
