Through the reoccurrence and repetition of the thoery
The best statement would be scientific laws describe phenomenon that can be observed in nature. Sometimes, laws are related to principle defining and predicting a certain happening without explaining its nature. It is different with ‘hypothesis’ or ‘theory’ as it aims to answer only the ‘what’ (observation only) of a happening instead of ‘why’ (explanation), however, it is tested empirically. Laws are already established by nature, while theories needed to be proven or tested and has the possibility to be rejected and accepted.
