In science, the word theory refers to solid fact. Like the theory of gravity. In our colloquial terms, it refers to an idea that hasn't been tested. The misunderstanding between science and everyday talk is part of the reason why a lot of people brush off evolution - they think that "theory" means its an idea but not fact.
