A scientific theory is a scientific hypothesis that has undergone numerous checks that confirm its validity as a theory.
What is needed for a theory?
For a theory to exist, it must start as a hypothesis, go through vigorous testing and re-testing, and remain true throughout the testing. If the hypothesis remains true, then it can be identified as a theory. If it does not, the scientist must return to his hypothesis to alter it or completely start over.[1]
Alternate usage
Scientists also speak about tentative theories that may have had little or no testing. For them, a theory is just a connected set of hypotheses that is worthy of scientific consideration. For example, they may discuss String Theory or a theory of extraterrestial intelligence, even though these theories have no supporting evidence.[Citation Needed]
