What is the difference between a scientific theory and a scientific law? Is there a fundamental difference or is a scientific law just a scientific theory that is extremely well accepted and supported. If that is the case, why is the Theory of Evolution not a scientific law, considering how much evidence there is supporting it? Also, I believe I have read that there is a Theory of Gravity as well as a Law of Gravity. Is this true? If it is, does that mean there is a fundamental difference between the two? Thanks for any help.
