A theory is an explanation of an idea that is broad in scope and supported by a large body of evidence. It is not simply an idea, but rather a tested and confirmed explanation for observations and phenomena. The key difference between a theory and a hypothesis is that a hypothesis is an idea that has yet to be tested, while a theory is supported by multiple lines of evidence.
