A law is a universal truth. Regardless of the situation the law will always occur.

For example, in Geology we have 4 laws.

1)The Law of Superposition

2)The Law of Original Horizontality

3)The Law of Uniformatarianism

4)The Law of Cross-Cutting

No matter where you are in the universe these laws will always prove true. Superposition states that if you have two rocks. The rock on top is ALWAYS younger than the rock on the bottom.

A theory means it could become a law but we have no evidence to back it up. An example in Geology is the Core-Dynamo theory. This is the idea our planets magnetic fields are formed in the core. Harrison Schmidt an Apollo astronaut proved the theory true when he collected this rock [https://en.wikipedia.org/wiki/Troctolite_76535](https://en.wikipedia.org/wiki/Troctolite_76535) from the lunar surface. But we only have one example. We have to drill to our own core to prove it to be universal.
