What is the difference between a theory and scientific law?
A theory is a proposed idea as an explaination to a problem. A scientific law is a tested and experimentally proven idea that can be considered as truth; until experimentally disproven. Newton's law of gravity was law, proven by experimental observations, right up until Einstein developed special relativity and it was experimentally proven. Thus disproving Newton's "law". String theory is an idea that is quite appealing to physicists, but there is no experimental proof to its validity, so it remains as just a theory.
