In law and ethics, universal law or universal principle refers as concepts of legal legitimacyactions, whereby those principles and rules for governing human beings conduct which are most universal in their acceptability, their applicability, translation, and philosophical basis, are therefore considered to be most legitimate. They are universal and absolute. From this disquisition, we can easily define the fundamental theoretical criteria, which a natural law must fulfill in order to be called "Universal Law". These are:
1. The law must hold true for anorganic and organic matter. 2. The law must be presented in a mathematical way, e.g. as a mathematical equation
"for all known physical laws are mathematical equations."
3. The law must be empirically verified without exception by all natural phenomena. 4. The law must integrate all known physical laws;
"for instance, one has to prove that all known distinct physical laws as mentioned
can be derived from this "Universal Law".
In this case, all known physical laws are mathematical applications of one single law of
Nature.
Alternatively, one has to show that all known fundamental constants in physics are
interrelated and can be derived from each other. In this way, one can integrate for the
first time gravitation with the other three fundamental forces and ultimately
unify physics."
that's why i said to Erik that he can't make purpose a universal law
