then why do they have different pages and different explanations.
Even do not find similarities between the two which strengthens that law and causality are the same.
Law Manipulation Page
Causality Manipulation Page
I don't understand why you say that causality is a law, because you don't even explain anything about it. but the fact that they both have different explanations and pages should make them not the same thing, because if they were the same we wouldn't need to have more than one page in our wiki just for the same thing.
well maybe if you have a good reason you can start a thread about it about deleting one of the pages and merging them.
