Question

Which term refers to a universal fact sometimes based on mathematical equations?

Answer 1

Scientific law. For example, Law of Universal Gravitation.

Answer 2

Answer:

Scientific Law.

Explanation:

A law is a mathematical description of a phenomenon, specifically a natural one, in this case. The difference with a theory, for example, is that it is not yet proven to be a universal fact, which a law is. Take for example the Laws of Thermodynamics or the Universal Law of Gravitation, both of these have been proven to be universal by mathematical equations.
