    Good luck finding any nontrivial law that applies to each and every instance of a human construct. “Money can be exchanged for goods and services” until you show up at a store with 10 kilograms of 1-cent coins. A single violation (or even many) don’t mean the underlying law (or rule or principle or guideline or whatever ‘less strict’ version you want to call it) is bad.

    Newton’s gravity is wrong. There’s no arguing about that. But still every middle-schooler around the world learns it because it is ‘good enough’ in all but extraordinarily special cases.

      You must be new to science. Congrats on starting the journey! To help with your learning, you should know Newton gave 3 laws which hold up surprisingly well. Check them out!

      Something else important is that gravity exists as a constant and can be found based on how much mass is involved. For example, on earth, it is a set acceleration of 9.8 m/s2.

      As a counter point, economics is allergic to labeling the axis on graphs except to show vague ideas like supply and demand. It is a field of study based on salesmanship and social inertia, not real science.
