Almost all of the things in physics are known only as observations, and as "laws" which fit with observations and allow us to predict the results of the similar observations. Then we intentionally try to find some observation that makes us refining the rules. Like Lorentz's formulas are the refinement of some Newtonian "laws." That's how science works.
