Yeah, theory is the next best thing to fact in science. A theory is something that there is very strong evidence in favor of. Newer ideas which are unproven or less rigorously tested are referred to as hypotheses.

The colloquial term "theory" corresponds better with the scientific term "hypothesis" than the scientific term "theory".
