In this Universe, there are very few fundamental properties that cannot be derived from something simpler. The rules governing biological systems are rooted in chemical interactions, bonds, and applied voltages. The rules of chemistry can be derived from more fundamental physical laws that govern all particles. And if you strip down the components of any physical system, you’ll eventually arrive at the simplest descriptions of reality we know of: the particles and interactions that make up all of our known reality. While all the particles that exist have their own specific, unique properties, there are only a few that define them, such as mass, electric charge, color charge, and weak hypercharge. Yet why the particles have the properties they do is not fully understood; the values of the fundamental constants behind the Universe cannot be derived from anything presently known.
